News & Research:

• A Healthy Lifestyle Halves The Risk Of Premature Death In Women - Science Daily, 9/16/08 - "Over half of deaths in women from chronic diseases such as cancer and heart disease could be avoided if they never smoke, keep their weight in check, take exercise and eat a healthy diet low in red meat and trans-fats"
• Clean living 'slows cell ageing' - BBC News, 9/15/08 - "Among 24 men asked to adopt healthy lifestyle changes for a US study in The Lancet Oncology, levels of telomerase increased by 29% on average ... Telomerase repairs and lengthens telomeres, which cap and protect the ends of chromosomes housing DNA ... 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. The researchers found a 26% increased risk of death from any cause for the quartile of participants with the lowest vitamin D levels compared to those with the highest levels" - See vitamin D products at iHerb.
• 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.
• Dietary lipoic acid supplementation can mimic or block the effect of dietary restriction on life span -Mech Ageing Dev. 2008 Apr 22;129(6):341-348 - "Ad libitum feeding a diet supplemented with lipoic acid can therefore act as mimetic of DR to extend survival" - See Doctor's Best, Best Stabilized R-Lipoic Acid Na-RALA 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.
• Serum Dehydroepiandrosterone Sulfate Levels Predict Longevity in Men: 27-Year Follow-Up Study in a Community-Based Cohort (Tanushimaru Study) - J Am Geriatr Soc. 2008 Apr 18 - "in men after adjustments for age, systolic blood pressure, and fasting plasma glucose showed significantly (log-rank stat =10.6; P<.001) greater longevity in the highest group (200 mug/dL) than in the moderate (130-199 mug/dL) or lowest groups (129 mug/dL)" - See DHEA 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.
• Four Health Behaviors Can Add 14 Extra Years Of Life - Science Daily, 1/8/08 - "People who adopt four healthy behaviours -- not smoking; taking exercise; moderate alcohol intake; and eating five servings of fruit and vegetables a day -- live on average an additional fourteen years of life compared with people who adopt none of these behaviours"
• Herbal Extract Found To Increase Lifespan - Science Daily, 12/5/07 - "Flies that ate a diet rich with Rhodiola rosea, an herbal supplement long used for its purported stress-relief effects, lived on an average of 10 percent longer than fly groups that didn’t eat the herb ... Although this study does not present clinical evidence that Rhodiola can extend human life, the finding that it does extend the lifespan of a model organism, combined with its known health benefits in humans, make this herb a promising candidate for further anti-aging research ... Rhodiola rosea ... has been used by Scandinavians and Russians for centuries for its anti-stress qualities ... patients taking a Rhodiola extract called SHR-5 reported fewer symptoms of depression than did those who took a placebo" - See Rhodiola Rosea products at iHerb.
• Fit Beats Fat for a Longer Life - WebMD, 12/4/07 - "Fitness was found to be a strong predictor of longevity in the study, which involved adults ages 60 and older, while obesity had little influence on death risk"
• Could Hydrogen Sulfide Hold The Key To A Long Life? - Science Daily, 12/4/07
• Fat Hormone May Contribute To Longevity - Science Daily, 11/21/07 - "long-lived Snell dwarf mice burn less glucose and more fatty acids during periods of fasting, and as a result produce fewer free radicals ... The key to this switch may be adiponectin, a hormone produced by fat cells that helps lower glucose production and stimulates cells to use fat for energy instead. The researchers found that Snell mice had three times as much adiponectin in their blood as control mice" - See my adiponectin page for ways to increase it.  Something that was also in today's abstracts was pioglitazone, which increased adiponectin 156%.
• Drug Commonly Used To Treat Bipolar Disorder Dramatically Increases Lifespan In Worms - Science Daily, 10/30/07 - "Nematode worms treated with lithium show a 46 percent increase in lifespan, raising the tantalizing question of whether humans taking the mood affecting drug are also taking an anti-aging medication" - See lithium products at OffshoreRX.com  or iHerb.
• Can Fat Be Fit?  -- Scientific American, 9/07
• Avoiding Sweets May Spell A Longer Life, Study In Worms Suggests - Science Daily, 10/2/07 - "A new study in Cell Metabolism reveals that worms live to an older age when they are unable to process the simple sugar glucose"
• Loneliness Can Speed Aging - WebMD, 8/20/07 - "lonely people live in a heightened sense of arousal, which could have long-term effects on heart disease and other health problems"
• Vitamin Extends Life In Yeast, Scientists Find - Science Daily, 5/3/07 - "providing a newly discovered vitamin activates the yeast anti-aging gene product Sir2, which resembles sirtuins found in humans. The new work builds on Brenner's prior discovery of the vitamin, termed NR (nicotinamide riboside), a natural product found in milk. Like the B3 vitamin, niacin, NR is a precursor to a versatile cellular factor that is vital for all life"

• Cell Mutations That Lead To Apoptosis May Contribute To Aging In Mammals - Science Daily, 7/15/05 - "mutations in the mitochondria caused by obesity and lack of exercise -- not oxidative stress from free radicals -- may be a key factor in the aging process"
• Obesity, Smoking Linked to Faster Aging - WebMD, 6/13/05 - "Telomeres are the tips of the chromosomes, which contain DNA. They gradually shorten over a lifetime ... The difference in telomere length between being lean and being obese corresponds to 8.8 years of aging ... Obesity and smoking are important risk factors for many age-related diseases. Both are states of heightened oxidative stress … and inflammation"
• Anti-aging Enzyme's Secrets Revealed - Science Daily, 4/1/05
• Mountain Life Spells Longer Life - Science Daily, 3/29/05 - "as blood lipids and blood pressure were higher among the mountain residents, other 'protective' factors must be at play ... living at moderately high altitude produces long term physiological changes in the body to enable it to cope with lower levels of oxygen, and that this, combined with the exertion required to walk uphill regularly on rugged terrain, could give the heart a better work-out"
• Live long, the Okinawan way - Maui News, 1/14/05
• System That Regulates Blood Pressure May Also Affect Aging - Science Daily, 11/22/04
• Social & Environmental Factors Play Important Role In How People Age, Two Studies Find - Science Daily, 9/14/04 - "those who scored high on positive affect were significantly less likely to become frail. Each unit increase in baseline positive affect score was associated with a three percent decreased risk of frailty"
• Healthy Aging Requires Healthy Attitudes - WebMD, 9/13/04 - "the patients who exhibited more positive emotions were significantly less likely to become frail. For example, every point increase in a senior's positive effect score at the start of the study was associated with a 3% decreased risk of frailty"
• Why do the Japanese live so long? - Guardian Unlimited, 6/10/04 - "People in Japan eat a third fewer calories than the typical North American. What they eat is also important: more seafood and, hence, healthy fish oils ... the Japanese are less sedentary than westerners, and Japan a less stressed society"
• Insulin Plays Central Role In Aging, Brown Scientists Discover - Science Daily, 6/4/04 - "insulin regulates its own production and that it directly regulates tissue aging. The principle: Keep insulin levels low and cells are stronger, staving off infection and age-related diseases such as cancer, dementia and stroke"
• Insulin plays central role in ageing, explains benefits of calorie reduction - Nutra USA, 6/3/04 - "if insulin levels remain low, cells are stronger and can ward off infection and age-related diseases such as cancer, dementia and stroke"
• Drosophila dFOXO controls lifespan and regulates insulin signalling in brain and fat body - Nature. 2004 Jun 3;429(6991):562-6
• DNA damage could be a start to aging, study suggests - USA Today, 5/26/04 - "the results are also consistent with the theory that so-called "free radicals" play a role in aging"
• Social Connections Build Healthier Lives - WebMD, 4/30/04 - "the prevalence of ill health was highest among those who rarely or never attended church and lowest among those that attended church regularly. Members of civic groups or those who volunteered regularly were also more likely to be completely healthy and less likely to report complete ill health than others"
• How to Age Well - WebMD, 10/27/03 - "What made them different than the other half? One thing stands out. Those who stayed healthy had perfectly healthy hearts. They didn't even have "subclinical" heart problems, the ones so minor they can only be detected by testing ... For men, having subclinical heart disease was like being 6.5 years older. For women, it was like being 5.5 years older ... refrain from smoking, lower their blood lipids, watch blood pressure, and avoid obesity through diet and exercise"
• Longevity May Run in Your Blood - WebMD, 10/14/03 - "the HDL and LDL particle sizes were significantly larger in the exceptionally old adults compared with both control groups, regardless of their cholesterol levels ... this trait was also associated with lower rates of high blood pressure, heart disease, and other health problems that account for a large number of deaths among the elderly"
• Does Growing Old Cause Cancer? - WebMD, 9/25/03
• The Serious Search for an Anti-Aging Pill - Scientific America, 8/03 - "Regrettably, however, 2DG has a fatal flaw preventing it from being the "magic pill" we were hoping for. Though safe at certain low levels, it apparently becomes toxic for some animals when the amount delivered is raised just a bit or given over long periods ... Treatment with antidiabetic medications that enhance cellular sensitivity to insulin might be helpful as well, as long as the amounts given do not cause blood glucose levels to fall too low ... Drugs that replicate only selected effects of caloric restriction could have a role to play as well. In theory, antioxidant vitamins might fit that bill"
• Children of Centenarians Have Delays in Age-Related Diseases - Doctor's Guide, 5/20/03 - "Fewer offspring of centenarians took prescription medicines, and they have lower weight and body mass compared to controls"
• Reaching 100 Is Largely a Matter of Genes - WebMD, 4/8/03
• Survival to 90 Years Linked to Low Weight in Young Adulthood and Exercise - Doctor's Guide, 4/8/03 - "baseline height and weight were not associated with mortality. However, a higher weight at age 21 was associated with increased odds of dying before reaching 90 years (OR=1.04 per 5 lb increase, P 0.0001). Those who exercised were 24-31% less likely to die by the age of 90 (OR=0.76, P 0.0001 for less than 1 hour per day, OR=0.69, P 0.0001 for 1 hour or more per day). Similarly, being in the mid tertile of BMI at baseline (22-24 for men, 20-23 for women) was associated with decreased odds of dying before age 90 (OR=0.70, P 0.0001)"
• The Fight for the Fountain of Youth - WebMD, 2/10/03
• A Prescription for Longevity - Physician's Weekly, 1/27/03 - "Okinawans have no genetic predisposition to longevity but rather benefit from the consumption of vegetables, tofu, seaweed; the pursuit of rigorous activity; and a low stress lifestyle. The authors claim if Americans could adopt the habits of Okinawans, "80 percent of the nation¹s coronary care units, one-third of the cancer wards, and a lot of nursing homes would be shut down.""
• Less Body Fat = Longer Life - WebMD, 1/23/03 - "Of the 250 mice in Bluher's study, half were specially bred to lack a response to the hormone insulin specifically in their fat cells -- he calls them "FIRKO mice." These mice were unable to store body fat. The normal mice were able to gain weight and body fat as usual ... The normal mice lived normal mouse-length lives -- 30 months. But at 30 months, 80% of the FIRKO mice were still alive ... His study suggests that increased metabolism is the secret to the FIRKO mouse's leanness and longevity"
• Longevity Runs In Families: Study Looks At Genetics, Environment - Intelihealth, 11/25/02 - "Female children of the centenarians weighed, on average, 146 pounds, while the female children of the control group weighed 158, on average.

• 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
• Cancer-Fighting Protein May Play Role In Aging, Mouse Study Suggests - Intelihealth, 1/3/02
• Optimism May Lower Heart Disease Risk In Older Men - Intelihealth, 12/13/01 - "The researchers found that the most highly optimistic men were less likely to develop heart disease than the most pessimistic men. In fact, each increase in the level of optimism was associated with an approximately 25% decreased risk of chest pain and heart disease"
• Secrets to Aging Gracefully - WebMD, 12/10/01 - "the happiest respondents had minor physical disabilities. They had regular social activities, could still think and reason well, and had an overall feeling of well-being -- and those were important to staying happy. In many cases, they were able to keep up socially because they had spent a lot of time cultivating relationships with friends and family when they were younger, and such investments in their time paid big dividends in terms of avoiding depression and staying vital later in life"
• Vegetarian diet on solid ground, experts say - USA Today, 12/7/01 - "McDougall points to a recent study in the Archives of Internal Medicine that looked at Seventh-Day Adventists in California, a group made up mostly of vegetarians. The 12-year of study of 34,192 people found that on average, group members lived 10 years longer than the general population ...
