• Tiny amounts of alcohol dramatically extend a worm's life, but why? - Science Daily, 1/20/12 - "How little ethanol is that? ... The concentrations correspond to a tablespoon of ethanol in a bathtub full of water or the alcohol in one beer diluted into a hundred gallons of water ... The scientists found that when they raised the ethanol level by a factor of 80, it did not increase the life span of the worms"
• Simple lifestyle changes can add a decade or more healthy years to the average lifespan, Canadian study shows - Science Daily, 10/22/11 - "Achieving these seven simple lifestyle factors gives people a 90 per cent chance of living to the age of 90 or 100, free of not only heart disease and stroke but from a number of other chronic illnesses including cancer ... 1. GET ACTIVE ... 2. KNOW AND CONTROL CHOLESTEROL LEVELS ... 3. FOLLOW A HEALTHY DIET ... 4. KNOW AND CONTROL BLOOD PRESSURE ... 5. ACHIEVE AND MAINTAIN A HEALTHY WEIGHT ... 6. MANAGE DIABETES ... 7. BE TOBACCO FREE"
• Why muscles weaken with age and points to possible therapy - Science Daily, 8/2/11 - "As we grow older, our skeletal muscles tend to wither and weaken, a phenomenon known as sarcopenia. Sarcopenia, which begins to appear at around age 40 and accelerates after 75, is a major cause of disability in the elderly. Exercise can help counter the effects of age-related muscle loss ... Both the aging process and the genetic defect responsible for muscular dystrophy cause an increase in the production of oxygen free radicals, highly reactive and harmful molecules. "Our data suggest that this sets up a vicious cycle, in which the free radicals cause ryanodine receptors to leak calcium into the cell. The calcium poisons mitochondria -- organelles that power the cell -- leading to the release of even more free radicals. This, in turn, causes more calcium leakage. With less calcium available for contraction, the muscles get weaker," ... The study also points to a possible therapy for sarcopenia: an experimental drug called S107 ... "Most investigators in the field of aging have been saying that the way to improve muscle strength is to build muscle mass, using such therapies as testosterone, growth hormone, and insulin-like growth factor-1," says Dr. Marks. "But an increase in muscle mass is not necessarily accompanied by an increase in muscle function"
• U.S. Death Rate Hits Record Low - WebMD, 3/16/11 - "The 15 leading causes of death in 2009 and the decreases in associated death rates were reported as follows: ... 1.Heart disease: 3.7% ... 2.Cancer: 1.1% ... 3.Chronic lower respiratory diseases: 4.1% ... 4.Stroke: 4.2% ... 5.Accidents: 4.1% ..."
• Keys to long life? Not what you might expect - Science Daily, 3/12/11 - ""Don't work too hard, don't stress," doesn't work as advice for good health and long life. Subjects who were the most involved and committed to their jobs did the best. Continually productive men and women lived much longer than their more laid-back comrades ... "One of the findings that really astounds people, including us, is that the Longevity Project participants who were the most cheerful and had the best sense of humor as kids lived shorter lives, on average, than those who were less cheerful and joking. It was the most prudent and persistent individuals who stayed healthiest and lived the longest." ... Part of the explanation lies in health behaviors -- the cheerful, happy-go-lucky kids tended to take more risks with their health across the years, Friedman noted. While an optimistic approach can be helpful in a crisis, "we found that as a general life-orientation, too much of a sense that 'everything will be just fine' can be dangerous because it can lead one to be careless about things that are important to health and long life. Prudence and persistence, however, led to a lot of important benefits for many years"
• Can Exercise Keep You Young? - NYTimes.com, 3/2/11 - "in heartening new research published last week in The Proceedings of the National Academy of Sciences, exercise reduced or eliminated almost every detrimental effect of aging in mice that had been genetically programmed to grow old at an accelerated pace ... mitochondria can accumulate small genetic mutations, which under normal circumstances are corrected by specialized repair systems within the cell. Over time, as we age, the number of mutations begins to outstrip the system’s ability to make repairs, and mitochondria start malfunctioning and dying ... Half of the mice were allowed to run on a wheel for 45 minutes three times a week, beginning at 3 months ... At 8 months, when their sedentary lab mates were bald, frail and dying, the running rats remained youthful. They had full pelts of dark fur, no salt-and-pepper shadings. They also had maintained almost all of their muscle mass and brain volume. Their gonads were normal, as were their hearts. They could balance on narrow rods, the showoffs ... But perhaps most remarkable, although they still harbored the mutation that should have affected mitochondrial repair, they had more mitochondria over all and far fewer with mutations than the sedentary mice had"
• Happiness improves health and lengthens life - Science Daily, 3/1/11 - "We reviewed eight different types of studies ... the general conclusion from each type of study is that your subjective well-being -- that is, feeling positive about your life, not stressed out, not depressed -- contributes to both longevity and better health among healthy populations ... Laboratory experiments on humans have found that positive moods reduce stress-related hormones, increase immune function and promote the speedy recovery of the heart after exertion. In other studies, marital conflicts and high hostility in married couples were associated with slow wound healing and a poorer immune response"
• Fountain of youth from the tap? Environmental lithium uptake promotes longevity, scientists demonstrate in worms - Science Daily, 2/18/11 - "A regular uptake of the trace element lithium can considerably promote longevity ... even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans ... the Jena scientists analyzed the mortality rate in 18 adjacent Japanese municipalities in relation to the amount of lithium contained in tap water from the respective regions. "We found that the mortality rate was considerably lower in those municipalities with more lithium in the drinking water," Ristow explains the key finding. In a second experiment, the Jena scientists examined exactly this range of concentration in the model organism C. elegans. The result was confirmed: "The average longevity of the worms is higher after they have been treated with lithium at this dosage," ... we know already that a higher uptake of lithium through drinking water is associated with an improvement of psychological well-being and with decreased suicide rates" - See lithium products at iHerb.
• Eat fiber, live longer - MSNBC, 2/14/11 - "Most Americans aren't getting enough roughage in their diets. The average American eats only about 15 grams of fiber each day, much less than the current daily recommendation of 25 grams for women and 38 grams for men, or 14 grams per 1,000 calories. For example, a slice of whole wheat bread contains 2 to 4 grams of fiber ... In the new study, the people who met the guidelines were less likely to die during a nine-year follow-up period ... The men and women who ate the highest amount of fiber were 22 percent less likely to die from any cause compared to those who ate the lowest amount"
• Relation Between High-Density Lipoprotein Cholesterol and Survival to Age 85 Years in Men (from the VA Normative Aging Study) - Am J Cardiol. 2011 Feb 4 - "We categorized initial HDL cholesterol into <40 mg/dl (reference group), 40 to 49 mg/dl, or ≥50 mg/dl ... Treating HDL cholesterol as a continuous predictor, we also determined the HR for each 10-mg/dl increment in HDL cholesterol. Fully adjusted HR (95% confidence interval) for survival to 85 years of age for participants with an initial HDL cholesterol level ≥50 mg/dl compared to the reference was 0.72 (0.53 to 0.98). Each 10-mg/dl increment in HDL cholesterol was associated with a 14% (HR 0.86, 0.78 to 0.96) decrease in risk of mortality before 85 years of age. In conclusion, after adjusting for other factors associated with longevity, higher HDL cholesterol levels were significantly associated with survival to 85 years of age" - See Twinlab niacin 1000mg at iHerb (niacin increases HDL).
• Smoking, obesity to blame for lag in U.S. lifespan - MSNBC/Associated Press, 1/25/11 - "The U.S. spends more on health care than any other nation yet has worse life expectancy than many — and a new report blames smoking and obesity ... That may sound surprising, considering that public smoking is being stamped out here while it's common in parts of Europe. And obesity is a growing problem around the world ... But the U.S. led those unhealthy trends, lighting up and fattening up a few decades ahead of other high-income countries. And the long-term consequences are life expectancy a few years shorter than parts of Europe and Japan"
• High alpha-carotene levels associated with longer life - Science Daily, 11/22/10 - "Oxygen-related damage to DNA, proteins and fats may play a role in the development of chronic diseases like heart disease and cancer ... Carotenoids -- including beta-carotene, alpha-carotene and lycopene -- are produced by plants and microorganisms and act as antioxidants, counteracting this damage ... Compared with individuals with blood alpha-carotene levels between 0 and 1 micrograms per deciliter, the risk of death during the study period was 23 percent lower among who had concentrations between 2 and 3 micrograms per deciliter, 27 percent lower with levels between 4 and 5 micrograms per deciliter, 34 percent lower with levels between 6 and 8 micrograms per deciliter and 39 percent lower with levels of 9 micrograms per deciliter or higher" - Note:  There are over 600 carotenoids and some claim that taking large amounts of just one of them can cause a deficiency of the others.  See Nature's Way, Multi-Carotene Anti-oxidant at iHerb.
• Regular exercise reduces large number of health risks including dementia and some cancers, study finds - Science Daily, 11/15/10 - "Regular exercise can reduce around two dozen physical and mental health conditions and slow down how quickly the body ages ... Health conditions covered by the review include: cancer, heart disease, dementia, stroke, type 2 diabetes, depression, obesity and high blood pressure"
• US Hispanics Have Longer Life Expectancy Than White and Black Americans - ABC News, 10/14/10 - "long-term health has a lot to do with diet, and immigrants are far less likely to indulge in the types of fattening foods that have expanded the American waistline. Instead of fast food and processed products, immigrants tend to favor fruit, vegetables, rice and beans ... Experts add that Hispanic immigrants eat far less red meat, instead consuming less-expensive chicken ... Besides a healthy diet, Hispanic immigrants also have the strong social bonds with family and friends that longevity experts say promote a long and happy life -- including drinking and smoking less ... If you lose that family connectedness, then you tend to have more health problems ... The people across the board who live oldest and healthiest are people who are part of social networks" - Should they have added exercise to that? I’ve never seen any statistics but I think Hispanics might have on average more physically demanding jobs. I saw a study several years ago where postal workers that delivered mail door to door lived longer than postal workers in an office. I run or swim and hour and a half a day but when I take on a large project on my house I’m a lot sorer and start losing a pant size per week.
• Amino acid supplement makes mice live longer - Science Daily, 10/5/10 - "leucine, isoleucine, and valine extend the life span of single-celled yeast ... Animals that were given the extra amino acids over a period of months lived longer, with a median life span of 869 days compared to 774 days for untreated control animals, the researchers report. That's an increase of 12 percent ... The findings in older mice suggest that the supplementary mixture may be specifically beneficial for those who are elderly or ill" - See Now Foods, Branched Chain Amino Acids, 240 Capsules at iHerb, it contains the three of these.
• Women's study finds longevity means getting just enough sleep - Science Daily, 9/30/10 - "the secret to a long life may come with just enough sleep. Less than five hours a night is probably not enough; eight hours is probably too much ... sleeping 6.5 to 7.5 hours per night was associated with best survival ... when sleep was measured objectively, the best survival was observed among women who slept 5 to 6.5 hours ... Women who slept less than five hours a night or more than 6.5 hours were less likely to be alive at the 14-year follow-up"
• Some interesting info on telomeres that someone sent:
  • Telomere Length Linked to Outcomes in Aplastic Anemia - nih.gov, 9/27/10 - "Aplastic anemia patients with shorter chromosome tips, or telomeres, have a lower survival rate and are much more likely to relapse after treatment than those with longer telomeres ... the blood cells of some patients with severe aplastic anemia disease have extremely short telomeres ... nearly 60% of the patients responded to immunosuppressive therapy. Of those who responded, the patients with the shortest telomeres were most likely to have a later relapse. The scientists found that the rate of relapse dropped as telomere lengths increased ... The group of patients with the shortest telomeres was also at greater risk for a conversion to bone marrow cancer (24%) than the other 3 groups (3% to 13%). Survival rates differed as well. Only 66% of patients with the shortest telomeres survived at least 6 years, compared to an 84% survival rate for the other 3 groups combined"
  • Happy Healthy Long Life: There's No Way Around It: If You Want to Live Longer You've Just Got to Do It! Get Out There & Exercise! - 2/6/08 - "by the time you're 65, well, there's just not that much left. Which is exactly why not too many of us make it past 80, 90 or 100. Not to get you even more depressed about your rapidly shrinking telomeres, but there have been a number of studies that have shown how stress, especially in caregiver's of chronically ill children and spouses of Alzheimer's patients have accelerated telomere shrinking. One study even suggested that you can accelerate your biological age by as much as 17 years if you're exposed to what you perceive as high psychological stress! ... it looks as if it's a safe bet to start lengthening your telomeres now, by EXERCISING!"
• Coffee may protect against DNA damage: Study - Nutra USA, 9/7/10 - "coffee is one of the richest sources of polyphenols in the Western diet, with one cup of the stuff providing 350 milligrams of phenolics. Of these, the most abundant compounds coffee are chlorogenic acids, making up to 12 per cent of the green coffee bean. The most abundant of these compounds is caffeic acid ... The subjects were assigned to drink either 800 ml coffee or water daily for five days. Various measures of DNA damage were used ... At the end of the study, a reduction in DNA damage, as measured by a reduction in the formation of oxidised purines of 12.3 percent was observed in the coffee drinkers" -  [Abstract]
• Impact of paper filtered coffee on oxidative DNA-damage: Results of a clinical trial - Mutat Res. 2010 Aug 13 - "consumed 800ml coffee or water daily over 5 days ... The extent of DNA-migration attributable to formation of oxidised purines (formamidopyrimidine glycosylase sensitive sites) was decreased after coffee intake by 12.3%"
• Resveratrol May Slow Aging in Humans - Medscape, 8/6/10 - "the popular plant extract has been shown to prolong life and reduce the rate of aging in roundworms, fruit flies, and yeast, apparently because resveratrol affects a gene associated with longevity ... resveratrol suppressed the generation of “free radicals” -- unstable molecules known to cause oxidative stress and release pro-inflammatory substances into the blood, resulting in damage to the blood vessel lining ... resveratrol also showed suppression of the inflammatory protein tumor necrosis factor, or TNF, and other compounds that increase blood vessel inflammation and interfere with insulin action, causing insulin resistance and the risk of developing diabetes" - See Jarrow Resveratrol 100 at iHerb.

• Aging and longevity tied to specific brain region in mice - Science Daily, 7/28/10 - "mice with increased brain SIRT1 have internal mechanisms that make them use energy more efficiently, which helps them move around in search of food even after a long fast. This increased energy-efficiency could help delay aging and extend lifespan ... SIRT1 is at the center of a network that connects metabolism and aging" - Related articles on SIRT1:

  • Sirtuin1 may boost memory and learning ability; Discovery could lead to new drugs to fight Alzheimer's, other neurological diseases - Science Daily, 7/11/10 - "Resveratrol, found in wine, has been touted as a life-span enhancer because it activates a group of enzymes known as sirtuins, which have gained fame in recent years for their ability to slow the aging process. Now MIT researchers report that Sirtuin1 -- a protein that in humans is encoded by the SIRT1 gene -- also promotes memory and brain flexibility ... We have now found that SIRT1 activity also promotes plasticity and memory"
  • Slowing Aging: Anti-aging Pathway Enhances Cell Stress Response - Science Daily, 2/19/09 - "The researchers discovered a new molecular relationship critical to keeping cells healthy across a long span of time: a protein called SIRT1, important for caloric restriction and lifespan and activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it active. HSF1 in turn senses the presence of damaged proteins in the cell and elevates the expression of molecular chaperones to keep a cell's proteins in a folded, functional state. Regulation of this pathway has a direct beneficial effect to cells ... decrease in SIRT1 may help explain why protein misfolding diseases, such as Alzheimer's, Parkinson's, Huntington's and adult-onset diabetes, are diseases of aging"
  • Drug 'tricks body to lose weight' - BBC News, 11/5/08 - "The drug SRT1720 - a chemical cousin of red wine extract resveratrol - targets the protein SIRT1, which is thought to combat ageing ... The French team from the University Louis Pasteur became interested in the SIRT1 protein after earlier studies showing resveratrol countered some effects of a high-calorie diet via SIRT1" - See Jarrow Resveratrol 100 at iHerb.
  • Wine Compound Spurs Diabetes Research - WebMD, 11/29/07 - "In October, Chinese researchers reported that resveratrol curbs insulin resistance in mice. Insulin is a hormone that controls blood sugar. Insulin resistance can lead to type 2 diabetes ... Like resveratrol, the lab-made chemicals activate a gene called SIRT1, making the diabetic mice more sensitive to insulin ... the newly developed chemicals are 1,000 times more potent than resveratrol"
  • Resveratrol regulates human adipocyte number and function in a Sirt1-dependent manner - Am J Clin Nutr. 2010 May 12 - "Taken together, our data suggest that resveratrol influences adipose tissue mass and function in a way that may positively interfere with the development of obesity-related comorbidities. Thus, our findings open up the new perspective that resveratrol-induced intracellular pathways could be a target for prevention or treatment of obesity-associated endocrine and metabolic adverse effects"
  • Resveratrol Modulates Tumor Cell Proliferation and Protein Translation via SIRT1-Dependent AMPK Activation - J Agric Food Chem. 2009 Nov 20 - "Similar to those effects associated with caloric restriction (CR), resveratrol has multiple beneficial activities, such as increased life span and delay in the onset of diseases associated with aging ... Here, we show that resveratrol activated AMPK in both ER-positive and ER-negative breast cancer cells ... Here, we show that resveratrol activated AMPK in both ER-positive and ER-negative breast cancer cells. Once activated, AMPK inhibited 4E-BP1 signaling and mRNA translation via mammalian target of rapamycin (mTOR). Moreover, we also found that AMPK activity mediated by resveratrol in cancer cells was due to inducing the expression of Sirtuin type 1 (SIRT1) via elevation in the cellular NAD(+)/NADH in ER-positive cells. To our knowledge, we demonstrate here for the first time that resveratrol induces the expression of SIRT1 protein in human cancer cells. These observations raise the possibility that SIRT1 functions as a novel upstream regulator for AMPK signaling and may additionally modulate tumor cell proliferation. Targeting SIRT1/AMPK signaling by resveratrol may have potential therapeutic implications for cancer and age-related diseases"
  • Resveratrol inhibits the expression of SREBP1 in cell model of steatosis via Sirt1-FOXO1 signaling pathway - Biochem Biophys Res Commun. 2009 Mar 13;380(3):644-9 - "Our results suggest that resveratrol may attenuate fat deposition by inhibiting SREBP1 expression via Sirt1-FOXO1 pathway and thus may have application for the treatment of NAFLD"
  • Resveratrol protects cardiomyocytes from hypoxia-induced apoptosis through the SIRT1-FoxO1 pathway - Biochem Biophys Res Commun. 2008 Dec 3 - "Loss of cardiomyocytes through apoptosis has been proposed as a cause of ventricular remodeling and heart failure. Ischemia- and hypoxia-induced apoptosis of cardiomyocytes reportedly plays an important role in many cardiac pathologies. We investigated whether resveratrol (Res) has direct cytoprotective effects against ischemia/hypoxia for cardiomyocytes. Exposure of H9c2 embryonic rat heart-derived cells to hypoxia for 24h caused a significant increase in apoptosis, as evaluated by TUNEL and flow cytometry, while treatment with 20muM Res greatly decreased hypoxia-induced apoptosis in these cells. Exposure of the cells to Res (20muM) caused rapid activation of SIRT1, which had a dual effect on FoxO1 function: SIRT1 increased FoxO1's ability to induce cell cycle arrest, but inhibited FoxO1's ability to induce cell death. This effect could be reversed by SIRT1 inhibition. Results of our study indicate that Res inhibits hypoxia-induced apoptosis via the SIRT1-FoxO1 pathway in H9c2 cells. This polyphenol may have potential in preventing cardiovascular disease, especially in coronary artery disease (CAD) patients"
• Calorie restriction: what recent results suggest for the future of ageing research - Eur J Clin Invest. 2010 May;40(5):440-50 - "the search for substances that can reproduce the beneficial physiologic responses of CR without a requisite calorie intake reduction, termed CR mimetics (CRMs), has gained momentum. Material and methods Recent articles describing health and lifespan results of CR in nonhuman primates and short-term human studies are discussed. Additional consideration is given to the rapidly expanding search for CRMs. Results The first results from a long-term, randomized, controlled CR study in nonhuman primates showing statistically significant benefits on longevity have now been reported. Additionally, positive results from short-term, randomized, controlled CR studies in humans are suggestive of potential health and longevity gains, while test of proposed CRMs (including rapamycin, resveratrol, 2-deoxyglucose and metformin) have shown both positive and mixed results in rodents"
• Eat less, live longer? - New Scientist, 6/3/10 - "One piece of evidence for this idea comes from studies in fruit flies and rodents. If these animals are fed special diets with less amino acids - the building blocks of proteins - they can eat as many calories as they want and still live longer ... The protein theory is bad news for people on low-carbohydrate weight-loss plans like the Atkins diet. "I'd be wary of diets that put a heavy emphasis on protein," says Piper. "It's hard to see how that could be healthy." Fontana goes one step further, saying that high-protein diets could risk accelerated ageing and cancer ... There may be another reason for vegans to celebrate. Studies on flies and rodents suggest that cutting intake of one particular amino acid, called methionine, lengthens life to a similar degree as calorie restriction. Proteins in meat and other animal products have high levels of methionine, so a vegan diet would score well by that measure, too"
• 15 best age-erasing superfoods - MSNBC, 5/25/10 - "Yogurt ... Various cultures claim yogurt as their own creation, but the 2,000-year-old food’s health benefits are not disputed: Fermentation spawns hundreds of millions of probiotic organisms that serve as reinforcements to the battalions of beneficial bacteria in your body, which keep your digestive tract healthy and your immune system in top form, and provide protection against cancer.

High phosphate levels may also increase the prevalence and severity of age-related complications, such as chronic kidney disease and cardiovascular calcification, and can also induce severe muscle and skin atrophy"
• Excessive alcohol consumption may lead to increased cancer risk - Science Daily, 4/21/10 - "Researchers have detected a link between alcohol consumption, cancer and aging that starts at the cellular level with telomere shortening ... Telomeres are found at the region of DNA sequences at the end of a chromosome, and are important for the genetic stability of cells. As people age, telomere length shortens progressively ... Since telomere shortening is thought to increase cancer risk, the researchers speculated that those with shorter telomeres due to heavy alcohol consumption would have an increased risk of cancer ... telomere length was dramatically shortened in those who consumed heavy amounts of alcohol; telomere length was nearly half as long as telomere length in the non-abusers (0.41 vs. 0.79 relative units)"

• Calorie restriction: Scientists take important step toward 'fountain of youth' - Science Daily, 12/26/09 - "They found that the normal cells lived longer, and many of the precancerous cells died, when given less glucose. Gene activity was also measured under these same conditions. The reduced glucose caused normal cells to have a higher activity of the gene that dictates the level of telomerase, an enzyme that extends their lifespan and lower activity of a gene (p16) that slows their growth. Epigenetic effects (effects not due to gene mutations) were found to be a major cause in changing the activity of these genes as they reacted to decreased glucose levels" - See my Insulin and Aging page.  Insulin controls glucose levels.  Insulin resistance causes high glucose.

• Melatonin: The Fountain Of Youth? - Science Daily, 6/22/09 - "Melatonin can slow down the effects of aging. A team at laboratoire Arago in Banyuls sur Mer (CNRS / Université Pierre et Marie Curie) has found that a treatment based on melatonin can delay the first signs of aging in a small mammal ... studied the long-term effects of melatonin on the Greater White-toothed shrew, a small nocturnal insectivorous mammal. Under normal conditions, this animal shows the first signs of aging after reaching 12 months, mainly through the loss of circadian rhythm in its activities. By continuously administering melatonin, starting a little before 12 months, the appearance of these first signs was delayed by at least 3 months, which is a considerable period in relation to the lifespan of this shrew ... Melatonin is now known to play several beneficial roles. These include being an antioxidant, an anti-depressant, and helping to remediate sleep problems" - See melatonin products at iHerb.
• Multivitamins linked to younger ‘biological age’: Study - Nutra USA, 5/27/09 - "Compared to non-multivitamin users, the researchers noted that that telomeres were on average 5.1 per cent longer for daily multivitamin users ... Whereas the evidence is not sufficient to conclude that these 2 dietary antioxidants mediated the observed relation, the results are consistent with experimental findings that vitamins C and E protect telomeres in vitro" - [Abstract]
• Multivitamin use and telomere length in women - Am J Clin Nutr. 2009 Jun;89(6):1857-63 - "After age and other potential confounders were adjusted for, multivitamin use was associated with longer telomeres. Compared with nonusers, the relative telomere length of leukocyte DNA was on average 5.1% longer among daily multivitamin users (P for trend = 0.002). In the analysis of micronutrients, higher intakes of vitamins C and E from foods were each associated with longer telomeres, even after adjustment for multivitamin use. Furthermore, intakes of both nutrients were associated with telomere length among women who did not take multivitamins"
• Half A Glass Of Wine A Day May Boost Life Expectancy By Five Years - Science Daily, 4/29/09 - "light long term alcohol consumption of all types—up to 20 g a day— extended life by around two extra years compared with no alcohol at all. Extended life expectancy was slightly less for those who drank more than 20 g ... men who drank only wine, and less than half a glass of it a day, lived around 2.5 years longer than those who drank beer and spirits, and almost five years longer than those who drank no alcohol at all"
• High IQ Linked To Reduced Risk Of Death - Science Daily, 3/13/09 - "a lower IQ was strongly associated with a higher risk of death from causes such as accidents, coronary heart disease and suicide ... the link between IQ and mortality could be partially attributed to the healthier behaviours displayed by those who score higher on IQ tests ... People with higher IQ test scores tend to be less likely to smoke or drink alcohol heavily, they eat better diets, and they are more physically active"
• Not So Sweet: Over-consumption Of Sugar Linked To Aging - Science Daily, 3/9/09 - "We know that lifespan can be extended in animals by restricting calories such as sugar intake ...it's not sugar itself that is important in this process but the ability of cells to sense its presence ... the lifespan of yeast cells increased when glucose was decreased from their diet. They then asked whether the increase in lifespan was due to cells decreasing their ability to produce energy or to the decrease in signal to the cells by the glucose sensor ... cells unable to consume glucose as energy source are still sensitive to the pro-aging effects of glucose. Conversely, obliterating the sensor that measures the levels of glucose significantly increased lifespan"
• Slowing Aging: Anti-aging Pathway Enhances Cell Stress Response - Science Daily, 2/19/09 - "The researchers discovered a new molecular relationship critical to keeping cells healthy across a long span of time: a protein called SIRT1, important for caloric restriction and lifespan and activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it active. HSF1 in turn senses the presence of damaged proteins in the cell and elevates the expression of molecular chaperones to keep a cell's proteins in a folded, functional state. Regulation of this pathway has a direct beneficial effect to cells ... decrease in SIRT1 may help explain why protein misfolding diseases, such as Alzheimer's, Parkinson's, Huntington's and adult-onset diabetes, are diseases of aging" - See Jarrow Resveratrol 100 at iHerb.
• Eating Less May Not Extend Human Life: Caloric Restriction May Benefit Only Obese Mice - Science Daily, 1/26/09 - "For lean mice – and possibly for lean humans, the authors of a new study predict – the anti-aging strategy known as caloric restriction may be a pointless, frustrating and even dangerous exercise ... Today there are a lot of very healthy people who look like skeletons because they bought into this ... Contrary to what is widely believed, caloric restriction does not extend (the) life span of all strains of mice ... caloric restriction begun in older mice – both in DBA and leaner C57 individuals – actually shortened life span"
• Old Gastrointestinal Drug Slows Aging, Researchers Say - Science Daily, 1/6/08 - "Recent animal studies have shown that clioquinol – an 80-year old drug once used to treat diarrhea and other gastrointestinal disorders – can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases ... clioquinol acts directly on a protein called CLK-1, often informally called "clock-1," and might slow down the aging process ... Because clock-1 affects longevity in invertebrates and mice, and because we're talking about three age-dependent neurodegenerative diseases, we hypothesize that clioquinol affects them by slowing down the rate of aging ... clioquinol was withdrawn from the market after being blamed for a devastating outbreak of subacute myelo-optic neuropathy (SMON) in Japan in the 1960s. However, because no rigorous scientific study was conducted at the time, and because clioquinol was used safely by millions before and after the Japanese outbreak, some researchers think its connection to SMON has yet to be proven" - I Googled clioquinol and I don't think it's available anywhere.
• Both Major Theories About Human Cellular Aging Supported By New Research - Science Daily, 12/30/08 - "old age is the final stage of a developmental program AND the result of a lifelong accumulation of unrepaired cellular and molecular damage ... When fatty acids build up, yeast cells explode from within, scattering their contents and spreading inflammation to neighboring cells ... In addition to cell death, the accumulation of fatty acids sets off chemical reactions that ultimately produce a lipid called diacylglycerol, which impairs many of the yeast's stress response-related defenses ... Low-calorie diets, which have been shown to increase lifespan and delay age-related disorders in nonhuman primates and other organisms, altered the way fats were processed in the yeast cells"
• Scientists Find a Possible Cause of Aging - NYTimes.com, 11/26/08 - "A new insight into the reason for aging has been gained by scientists trying to understand how resveratrol, a minor ingredient of red wine, improves the health and lifespan of laboratory mice. They believe that the integrity of chromosomes is compromised as people age, and that resveratrol works by activating a protein known as sirtuin that restores the chromosomes to health ... Dr. Sinclair has been taking large daily doses of resveratrol since he and others discovered five years ago that it activated sirtuin. “I’m still taking it and I feel great,” he said, “but it’s too early to say if I’m young for my age."" - See Jarrow Resveratrol 100 at iHerb.

These consisted of a diet high in fruit and vegetables, supplements of vitamins and fish oils, an exercise regimen and classes in stress management, relaxation techniques and breathing exercises"
• Low Vitamin D Levels Pose Large Threat To Health; Overall 26 Percent Increased Risk Of Death - Science Daily, 8/12/08 - "This translates overall to an estimated 26 percent increased risk of any death, though the number of deaths from heart disease alone was not large enough to meet scientific criteria to resolve that it was due to low vitamin D levels ... Previous results from the same nationwide survey showed that 41 percent of men and 53 percent of women are technically deficient in the nutrient, with vitamin D levels below 28 nanograms per milliliter" - See vitamin D products at iHerb.
• Running Slows the Effects of Aging - WebMD, 8/11/08 - "Older runners have fewer disabilities, remain more active as they get into their 70s and 80s, and are half as likely as non-runners to die early deaths, the study shows ... If you had to pick one thing to make people healthier as they age, it would be aerobic exercise ... The researchers used national death records to learn which participants died and why. Nineteen years into the study, 34% of the non-runners had died, compared with only 15% of the runners" - [Science Daily]
• Low Level of Vitamin D Ups Death Risk - WebMD, 8/11/08 - "Over an average follow-up period of about nine years, 1,806 participants died.

• Resveratrol, Found In Red Wine, Wards Off Effects Of Age On Heart, Bones, Eyes And Muscle - Science Daily, 7/3/08 - "This study, conducted and supported in part by the National Institute on Aging (NIA), part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice. The report confirms previous results suggesting the compound, found naturally in foods like grapes and nuts, may mimic, in mice, some of the effects of dietary or calorie restriction, the most effective and reproducible way found to date to alleviate age-associated disease in mammals" - See Jarrow Resveratrol 100 at iHerb.
• Substance In Red Wine, Resveratrol, Found To Keep Hearts Young - Science Daily, 6/4/08 - "Resveratrol is active in much lower doses than previously thought and mimics a significant fraction of the profile of caloric restriction at the gene expression level ... In animals on a restricted diet, 90 percent of those heart genes experienced altered gene expression profiles, while low doses of resveratrol thwarted age-related change in 92 percent. The new findings, say the study's authors, were associated with prevention of the decline in heart function associated with aging" - See Jarrow Resveratrol 100 at iHerb.
• Low-dose resveratrol may slow ageing: for mice at least - Nutra USA, 6/4/08 - "animals in the calorie-restriction and low-dose resveratrol groups had altered gene expression profiles in 90 and 92 per cent, respectively, in the heart ... In short, a glass of wine or food or supplements that contain even small doses of resveratrol are likely to represent "a robust intervention in the retardation of cardiac ageing,"" - See Jarrow Resveratrol 100 at iHerb.
• Red wine may protect heart from aging’s toll - MSNBC - 6/3/08 - "Resveratrol at low doses can retard some aspects of the aging process, including heart aging, and it may do so by mimicking some of the effects of caloric restriction, which is known to retard aging in several tissues and extend life span" - See resveratrol products at iHerb.

• Lifelong prebiotic supplements may enhance survival: rat study - Nutra USA, 4/24/08 - "In terms of survival, at 18 months of age, all the animals in the prebiotic group were still alive, compared to 76 per cent in the control group. After 24 months, 81 per cent of the rats in the prebiotic group were alive, compared to only 52 per cent of controls" - [Abstract] - See inulin products at iHerb.
• Effects of lifelong intervention with an oligofructose-enriched inulin in rats on general health and lifespan - Br J Nutr. 2008 Apr 11;:1-8 - "a diet with 10 % of an oligofructose-enriched inulin (Synergy1) ... During the whole intervention period, male rats receiving Synergy1 (SYN1-M) displayed lower body weight, cholesterol and plasma triacylglycerolaemia compared with the controls (Cont-M). The survival rate at 24 months of age of SYN1-M rats was 35.3 % greater than that of Cont-M rats. In female rats, the Synergy1 supplementation (SYN1-F) group also reduced body weight, cholesterol and triacylglycerolaemia levels, but results were less consistent over the experiment. The survival rate at 24 months of age in SYN1-F rats was 33.3 % greater compared with that of the control (Cont-F) group. To conclude, lifelong intervention with Synergy1 improved biological markers during ageing and survival rate (lifespan) of rats" - See inulin products at iHerb.

• Lipoic acid significantly restores, in rats, the age-related decline in vasomotion - Br J Pharmacol. 2008 Feb 25 - "In old animals, endothelium-dependent relaxation in aortic rings was decreased, GSH levels and its redox state in aortic endothelia were over 30% lower and nSMase activity and endothelial ceramide levels were three-fold increased, relative to young (2-4 mo) rats. LA treatment of old animals improved relaxation in aortic rings, reversed the changes in endothelial GSH, in nSMase activities and in ceramide levels. Similar effects on GSH levels and nSMase activity in old rats were also induced by treatment with GSH monoethylester. Activation (by phosphorylation) of eNOS was decreased by about 50% in old rats and this age-related decrease was partially reversed by LA treatment" - See Doctor's Best, Best Stabilized R-Lipoic Acid Na-RALA at iHerb.
• Sedentary Lifestyles Associated With Accelerated Aging Process - Science Daily, 1/28/08 - "Telomere length decreased with age, with an average loss of 21 nucleotides (structural units) per year. Men and women who were less physically active in their leisure time had shorter leukocyte telomeres than those who were more active. ... "The mean difference in leukocyte telomere length between the most active [who performed an average of 199 minutes of physical activity per week] and least active [16 minutes of physical activity per week] subjects was 200 nucleotides, which means that the most active subjects had telomeres the same length as sedentary individuals up to 10 years younger, on average."" - I'm must be in fat city on this one.  I must have averaged 60 minutes per day since I've been 18 which comes to 420 minutes per week.  Maybe that's the main reason people claim I look young. Plus I've always taken vitamin D which helps with telomere length also. - Ben
• Sustained Tubulo-interstitial Protection in SHRs by Transient Losartan Treatment: An Effect of Decelerated Aging? - Am J Hypertens. 2008 Jan 10 - "Transient losartan treatment reduces cell-turnover not only acutely but also for a prolonged period after drug withdrawal. This results in the long-term in reduced aging and attenuated tubulo-interstitial damage, suggesting there exists a modulating effect of angiotensin II (ANGII)-antagonism on long-term cell turnover" - Note:  Losartan is an ARB.  I would think that telmisartan (also and ARB and my recommendation for hypertension) would give the same effect.

• Warning Against 'Anti-Aging' Medicine - WebMD, 3/6/02 - Articles like this burn me up. Most people will be six feet under before those studies come in. I feel you need to go with the best scientific information available at the time. Also, Dr. Smith’s comment that "There is as yet no convincing evidence that administration of any specific compound, natural or artificial, can globally slow aging in people, or even in mice or rats" is absolutely false. Take for example the study published in the 2/19/02 Proceedings of the National Academy of Sciences on alpha lipoic acid and acetyl-l-carnitine or the studies with deprenyl and rats? I could go on and on. Some doctors think that the three credits in nutrition they got back in 1985 from text books written in the 70’s allow them to make bold lies without even reading the research.  LEF has references for their articles.  I guess if your a doctor, you can make bold statements like Dr. Smith's without references.  I agree with the following statement by Dr. Klatz: "To become a physician, you have to take the Hippocratic Oath, in which you swear to "do no harm." But there are many ways to interpret that phrase. As all Catholics are aware, there are sins of omission and sins of commission. Cutting off the wrong leg of a diabetic or operating on the wrong side of the head in a patient with a brain tumor as happened recently in two New York hospitals is clearly doing harm. But what about not keeping abreast of the latest diagnostic treatment or advances? Or failing to inform a patient of lifestyle changes or options that could drastically lower risk of disease? Or taking a authoritarian, I-know-better-than-you attitude that effectively cuts off all questions about alternative measures and treatments? All these "sins of omission" may end up doing you harm in terms of accelerated aging, disease, and death." - Ben
