Coffee/Caffeine

News & Research:

• Why Coffee May Reduce Diabetes Risk - WebMD, 1/13/12 - "The Chinese researchers looked at three major active compounds in coffee and their effect on stopping the toxic accumulation of the protein: ... Caffeine ... Caffeic acid or CA ... Chlorogenic acid or CGA ... All three had an effect. However, caffeic acid was best" - Note:  I've always thought that artichoke extract which is 6% chlorogenic acid would do the same thing:
  • Chlorogenic acid - Wikipedia, the free encyclopedia - "Chlorogenic acid is a hydroxycinnamic acid, a member of a family of naturally occurring organic compounds. These are esters of polyphenolic caffeic acid and cyclitol (-)-quinic acid"
• Caffeine study shows sport performance increase - Science Daily, 12/14/11 - "Mayur Ranchordas, a senior lecturer and performance nutritionist at Sheffield Hallam University, carried out studies on footballers using caffeine and carbohydrates combined in a drink ... There is already plenty of research that shows that caffeine and carbohydrate improve endurance, but this study shows that there is also a positive effect on skill and performance ... We found that the combination of carbohydrate and caffeine allowed players to sustain higher work intensity for the sprints, as well as improving shooting accuracy and dribbling during simulated soccer activity"
• Coffee consumption associated with decreased risk for basal cell carcinoma - Science Daily, 10/24/11 - "Data were taken from the Nurses' Health Study (Brigham and Women's Hospital) and the Health Professionals Follow-Up Study ... women who consumed more than three cups of coffee per day had a 20 percent reduction in risk for BCC, and men who consumed more than three cups per day had a nine percent risk reduction compared with people who consumed less than one cup per month"
• Increased caffeinated coffee consumption associated with decreased risk of depression in women, study finds - Science Daily, 9/26/11 - "During the 10-year follow-up period from 1996 to 2006, researchers identified 2,607 incident (new-onset) cases of depression. When compared with women who consumed one cup of caffeinated coffee or less per week, those who consumed two to three cups per day had a 15 percent decrease in relative risk for depression, and those consuming four cups or more per day had a 20 percent decrease in relative risk. Compared with women in the lowest (less than 100 milligrams [mg] per day) categories of caffeine consumption, those in the highest category (550 mg per day or more) had a 20 percent decrease in relative risk of depression. No association was found between intake of decaffeinated coffee and depression risk"
• Harvard study supports coffee’s anti-diabetes potential - Nutra USA, 9/21/11 - "Five cups of coffee per day for two months were associated with significant metabolic benefits and live function ... the metabolic benefits were more pronounced in caffeinated coffee, a result that supports the hypothesis that caffeine is responsible for some of the apparent benefits ... Coffee is also a rich source of polyphenols ... one cup of the stuff could provide 350 milligrams of phenolics ... Of these, the most abundant compounds in coffee are chlorogenic acids, making up to 12 per cent of the green coffee bean. The most abundant of these compounds is caffeic acid ... recruited 45 healthy, overweight coffee drinking 40 year olds ... volunteers were asked to drink five cups of coffee per day of instant caffeinated coffee, decaffeinated coffee, or water for eight weeks ... coffee consumption was associated with a 60% reduction in blood levels of a compound called interleukin-6, which can promote inflammation, compared with the water group ... In addition, levels of adiponectin – a hormone released from fat cells that plays an important role in the regulation of insulin sensitivity and energy – also decreased in the caffeinated, but not decaffeinated group" - [Abstract]
• Caffeine consumption linked to female infertility, study suggests - Science Daily, 7/20/11 - "By studying tubes from mice, Ward and his team discovered that caffeine stops the actions of specialized pacemaker cells in the wall of the tubes. These cells coordinate tube contractions so that when they are inhibited, eggs can't move down the tubes. In fact these muscle contractions play a bigger role than the beating cilia in moving the egg towards the womb ... This provides an intriguing explanation as to why women with high caffeine consumption often take longer to conceive than women who do not consume caffeine"
• The Body Odd - Coffee buzz protects brain from Alzheimer's - MSNBC, 6/29/11 - "the equivalent of four to five cups of caffeinated coffee every few days led to much improved memories in the Alzheimer’s mice ... Earlier research by Arendash and his colleagues showed that caffeine could at least partially block the production of beta amyloid, the sticky protein that clogs the brains of Alzheimer’s patients. They also found that a substance called granulocyte-colony stimulating factor, or GCSF, sparked the production of new axons, the communication cables that link nerve cells together, as well as new nerve cells themselves"
• Mystery ingredient in coffee boosts protection against Alzheimer's disease - Science Daily, 6/21/11 - "A yet unidentified component of coffee interacts with the beverage's caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer's disease. A new Alzheimer's mouse study by researchers at the University of South Florida found that this interaction boosts blood levels of a critical growth factor that seems to fight off the Alzheimer's disease process ... The new study does not diminish the importance of caffeine to protect against Alzheimer's. Rather it shows that caffeinated coffee induces an increase in blood levels of a growth factor called GCSF (granulocyte colony stimulating factor). GCSF is a substance greatly decreased in patients with Alzheimer's disease and demonstrated to improve memory in Alzheimer's mice ... The boost in GCSF levels is important, because the researchers also reported that long-term treatment with coffee (but not decaffeinated coffee) enhances memory in Alzheimer's mice. Higher blood GCSF levels due to coffee intake were associated with better memory ... First, GCSF recruits stem cells from bone marrow to enter the brain and remove the harmful beta-amyloid protein that initiates the disease. GCSF also creates new connections between brain cells and increases the birth of new neurons in the brain ... An increasing body of scientific literature indicates that moderate consumption of coffee decreases the risk of several diseases of aging, including Parkinson's disease, Type II diabetes and stroke"
• Why caffeine can reduce fertility in women - Science Daily, 5/23/11 - "Caffeine reduces muscle activity in the fallopian tubes that carry eggs from the ovaries to the womb"
• Coffee may reduce risk of lethal prostate cancer in men - Science Daily, 5/17/11 - "The researchers chose to study coffee because it contains many beneficial compounds that act as antioxidants, reduce inflammation, and regulate insulin, all of which may influence prostate cancer. Coffee has been associated in prior studies with a lower risk of Parkinson's disease, type 2 diabetes, gallstone disease, and liver cancer or cirrhosis ... Men who consumed the most coffee (six or more cups daily) had nearly a 20% lower risk of developing any form of prostate cancer ... Men who drank the most coffee had a 60% lower risk of developing lethal prostate cancer ... Even drinking one to three cups of coffee per day was associated with a 30% lower risk of lethal prostate cancer"
• Coffee reduces breast cancer risk, study suggests - Science Daily, 5/10/11 - "Researchers from Sweden compared lifestyle factors and coffee consumption between women with breast cancer and age-matched women without. They found that coffee drinkers had a lower incidence of breast cancer than women who rarely drank coffee. However they also found that several lifestyle factors affected breast cancer rates, such as age at menopause, exercise, weight, education, and a family history of breast cancer. Once they had adjusted their data to account for these other factors they found that the protective effect of coffee on breast cancer was only measurable for ER-negative breast cancer"
• New evidence that caffeine is a healthful antioxidant in coffee - Science Daily, 5/4/11 - "caffeine in coffee, tea, and other foods seems to protect against conditions such as Alzheimer's disease and heart disease on the most fundamental levels ... coffee is one of the richest sources of healthful antioxidants in the average person's diet. Some of the newest research points to caffeine (also present in tea, cocoa, and other foods) as the source of powerful antioxidant effects that may help protect people from Alzheimer's and other diseases ... In an effort to bolster scientific knowledge about caffeine, they present detailed theoretical calculations on caffeine's interactions with free radicals. Their theoretical conclusions show "excellent" consistency with the results that other scientists have report from animal and other experiments, bolstering the likelihood that caffeine is, indeed, a source of healthful antioxidant activity in coffee"
• Coffee doesn't increase high blood pressure risk - MSNBC, 4/21/11 - "followed them for up to 33 years ... But the chance of being diagnosed with the condition was no different between people who said they chugged more than five cups of coffee per day and those who drank very little"
• Espresso makers: Coffee in capsules contains more furan than the rest - Science Daily, 4/13/11 - "Coffee made in espresso makers, above all that made from capsules, contains more furan -- a toxic, carcinogenic compound -- than that made in traditional drip coffee makers, although the levels are still within safe health limits ... The reason for these higher levels is due to the fact that hermetically-sealed capsules prevent furan, which is highly volatile, from being released, while the coffee makers used to brew this coffee use hot water at higher pressures"
• Got a craving for fast food? Skip the coffee, study suggests - Science Daily, 4/1/11 - "a healthy person's blood sugar levels spike after eating a high-fat meal, but that the spike doubles after having both a fatty meal and caffeinated coffee -- jumping to levels similar to those of people at risk for diabetes ... saturated fat interferes with the body's ability to clear sugars from the blood and, when combined with caffeinated coffee, the impact can be even worse"
• Coffee drinking linked to reduced stroke risk in women - Science Daily, 3/10/11 - "Drinking more than a cup of coffee a day was associated with a 22 percent to 25 percent lower risk of stroke, compared with those who drank less ... The food frequency questionnaire made no distinction between regular and decaffeinated coffee but decaffeinated coffee consumption in the Swedish population is low ... Potential ways that coffee drinking might reduce the risk of stroke include weakening subclinical inflammation, reducing oxidative stress and improving insulin sensitivity"
• Why coffee protects against diabetes - Science Daily, 1/12/11 - "A protein called sex hormone-binding globulin (SHBG) regulates the biological activity of the body's sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG"

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]
• Olympic gold? A new effect of caffeine boosts performance - Science Daily, 6/29/10 - "high doses of caffeine directly increase muscle power and endurance during relatively low-intensity activities ... a caffeine dosage of 70 µM enhanced power output by ~6% during both types of activity.

• Coffee may protect against head and neck cancers - Science Daily, 6/22/10 - "participants who were regular coffee drinkers, that is, those who drank an estimated four or more cups a day, compared with those who were non-drinkers, had a 39 percent decreased risk of oral cavity and pharynx cancers combined"
• Coffee cuts risk of head, neck cancers - MSNBC, 6/22/10 - "Overall, the risk of developing head and neck cancers was 12 percent lower in people who drank coffee compared with those who didn't ... And the more coffee consumed, the lower the cancer risk. In those who gulped more than four cups a day, for instance, the risk was reduced by more than a third ... Besides caffeine, coffee contains more than a thousand chemicals ... the compounds cafestol and kahweol may be protective against carcinogens that would normally damage our genes"
• Women who choose boiled coffee run lower risk of breast cancer, Swedish study finds - Science Daily, 6/16/10 - "A major difference between boiled and filtered coffee is that the boiled version contains up to 80 times as much coffee-specific fatty acids ... Among women who drank boiled coffee more than four times a day there was a lowered risk of breast cancer compared with women who drank coffee less than once a day. Among women who drank filtered coffee there was an increased risk for early breast cancer (under 49 years old) and a decreased risk for late breast cancer (over 55 years old). Boiled-coffee drinkers, but not filtered-coffee drinkers, also had an increased risk of pancreatic cancer and lung cancer among men"
• New evidence that drinking coffee may reduce the risk of diabetes - Science Daily, 6/9/10 - "The scientists fed either water or coffee to a group of laboratory mice commonly used to study diabetes. Coffee consumption prevented the development of high-blood sugar and also improved insulin sensitivity in the mice, thereby reducing the risk of diabetes. Coffee also caused a cascade of other beneficial changes in the fatty liver and inflammatory adipocytokines related to a reduced diabetes risk. Additional lab studies showed that caffeine may be "one of the most effective anti-diabetic compounds in coffee,""

Abstracts:

• A Prospective Cohort Study of Coffee Consumption and Risk of Endometrial Cancer over a 26-Year Follow-Up - Cancer Epidemiol Biomarkers Prev. 2011 Nov 22 - "Coffee has been reported to lower levels of estrogen and insulin, two hormones implicated in endometrial carcinogenesis, but prospective data on the relation between coffee consumption and risk of endometrial cancer are limited ... Fewer than 4 cups of coffee per day were not associated with endometrial cancer risk. However, women who consumed 4 or more cups of coffee had 25% lower risk of endometrial cancer than those who consumed less than 1 cup per day (multivariable RR = 0.75; 95% CI = 0.57-0.97; P(trend) = 0.02). We found the similar association with caffeinated coffee consumption (RR for ≥4 vs. <1 cup/d = 0.70; 95% CI = 0.51-0.95). For decaffeinated coffee consumption, a suggestive inverse association was found among women who consumed 2 or more cups per day versus <1 cup/mo. Tea consumption was not associated with endometrial cancer risk"
• The effect of coffee on blood pressure and cardiovascular disease in hypertensive individuals: a systematic review and meta-analysis - Am J Clin Nutr. 2011 Aug 31 - "In 5 trials, the administration of 200-300 mg caffeine produced a mean increase of 8.1 mm Hg (95% CI: 5.7, 10.6 mm Hg) in systolic BP and of 5.7 mm Hg (95% CI: 4.1, 7.4 mm Hg) in diastolic BP. The increase in BP was observed in the first hour after caffeine intake and lasted ≥3 h. In 3 studies of the longer-term effect (2 wk) of coffee, no increase in BP was observed after coffee was compared with a caffeine-free diet or was compared with decaffeinated coffee. Last, 7 cohort studies found no evidence of an association between habitual coffee consumption and a higher risk of CVD ... In hypertensive individuals, caffeine intake produces an acute increase in BP for ≥3 h. However, current evidence does not support an association between longer-term coffee consumption and increased BP or between habitual coffee consumption and an increased risk of CVD in hypertensive subjects"
• Coffee Consumption and Prostate Cancer Risk and Progression in the Health Professionals Follow-up Study - J Natl Cancer Inst. 2011 May 17 - "Coffee contains many biologically active compounds, including caffeine and phenolic acids, that have potent antioxidant activity and can affect glucose metabolism and sex hormone levels ... The average intake of coffee in 1986 was 1.9 cups per day. Men who consumed six or more cups per day had a lower adjusted relative risk for overall prostate cancer compared with nondrinkers (RR = 0.82, 95% confidence interval [CI] = 0.68 to 0.98, P(trend) = .10). The association was stronger for lethal prostate cancer (consumers of more than six cups of coffee per day: RR = 0.40, 95% CI = 0.22 to 0.75, P(trend) = .03). Coffee consumption was not associated with the risk of nonadvanced or low-grade cancers and was only weakly inversely associated with high-grade cancer. The inverse association with lethal cancer was similar for regular and decaffeinated coffee (each one cup per day increment: RR = 0.94, 95% CI = 0.88 to 1.01, P = .08 for regular coffee and RR = 0.91, 95% CI = 0.83 to 1.00, P = .05 for decaffeinated coffee). The age-adjusted incidence rates for men who had the highest (≥6 cups per day) and lowest (no coffee) coffee consumption were 425 and 519 total prostate cancers, respectively, per 100 000 person-years and 34 and 79 lethal prostate cancers, respectively, per 100 000 person-years"

The RRs of CVD mortality across the same categories of coffee intake were 1, 0.99 (0.75, 1.31), 1.03 (0.80, 1.35), 0.97 (0.78, 1.21), and 1.25 (0.85, 1.84), respectively (P for trend = 0.76). Similarly, caffeine intake was not associated with total or CVD mortality. Finally, we observed no association of the most recent coffee and caffeine intakes with total and CVD mortality in the subsequent 2 y ... Consumption of filtered caffeinated coffee was not associated with CVD or all-cause mortality in women with CVD"
• Green tea and coffee consumption and its association with thyroid cancer risk: a population-based cohort study in Japan - Cancer Causes Control. 2011 May 12 - "Green tea consumption was not found to be associated with thyroid cancer risk in general. However, when women were stratified by menopausal status, the multivariable HR for ≥5 cups/day versus <1 cup/day was 1.66 (95% confidence interval (CI) = 0.85-3.23, trend p = 0.04) in premenopausal women, and was 0.47 (95% CI = 0.23-0.96, trend p = 0.06) in postmenopausal women. We found no association between coffee consumption and thyroid cancer risk in either sex"
• Higher Daily Coffee Intake Not Linked to Hypertension Risk - Medscape, 4/13/11 - "Habitual drinking of 3 cups/day or more of coffee is not associated with an increased risk for hypertension compared with less than 1 cup/day, but this risk was slightly elevated with light to moderate consumption of 1 to 3 cups/day"
• Cumulative Coffee Consumption and Reduced Risk of Oral and Oropharyngeal Cancer - Nutr Cancer. 2011 Mar 31:1 - "Tobacco smoking, alcohol drinking, and higher intake of bacon and deep-fried foods were directly related to disease; the inverse was observed to family income and salad intake. Coffee consumption and tobacco smoking were partially correlated (Spearman correlation coefficient 0.14 among cases, 0.31 among controls). When adjusted for all covariates, a cumulative coffee consumption higher than 18.0 daily liters × year during lifetime was indicated to be protective against disease (adjusted odds ratio 0.39, 95% confidence interval 0.16-0.94, P = 0.037). This observation may have pharmacological implications for clinical medication of these cancers and is relevant to programs aimed at reducing the burden of disease"

• Coffee consumption is inversely associated with type 2 diabetes in Chinese - Eur J Clin Invest. 2011 Jan 12 - "The prevalence of T2DM was 14·0% and 10·4% in men and women ... coffee intake was inversely associated with T2DM. Habitual coffee drinkers had 38-46% lower risk of T2DM than nondrinkers. Compared to nondrinkers, the adjusted odds ratios (ORs) for T2DM according to subjects with habitual coffee consumption (<1,1-6, ≥ 7 times per week) were 0·77 (0·52-1·13), 0·46 (0·28-0·76) and 0·37 (0·16-0·83), respectively. The decreasing ORs indicate a dose-response effect of coffee consumption on the likelihood of having T2DM (P < 0·001). A similar relationship was also evident in newly diagnosed T2DM (P < 0·05). The adjusted mean fasting glucose levels gradually decreased as the frequency of coffee consumption increased"

Tea consumption appeared to increase risk (OR: 1.93; 95% CI: 1.08-3.45), but after including the variables sugar/honey and cream/milk added to tea in the model, the risk estimate was attenuated and no longer statistically significant (OR: 1.77; 95% CI: 0.96-3.28 for those consuming more than one cup/day of tea compared to nonusers). There was a suggestion of a decreased risk associated with green tea, but the confidence interval included one (adjusted OR for one or more cups/week vs. none: 0.75; 95% CI: 0.48-1.18). We found an association with adding sugar/honey to tea, with those adding two or more teaspoons/cup having an OR of 2.66 (95% CI: 1.42-4.98; p for trend <0.01) after adjusting for relevant confounders. For sugar/honey added to coffee the corresponding OR was 1.43 (95% CI: 0.81-2.55). Our results indicate that sugars and milk/cream added to coffee and tea should be considered in future studies evaluating coffee and tea and endometrial cancer risk"
