Specific Recommendations:

News & Research:

  • Drinking coffee could lead to a longer life, scientist say - Science Daily, 7/10/17 - "Drinking coffee was associated with a lower risk of death due to heart disease, cancer, stroke, diabetes, and respiratory and kidney disease for African-Americans, Japanese-Americans, Latinos and whites ... People who consumed a cup of coffee a day were 12 percent less likely to die compared to those who didn't drink coffee. This association was even stronger for those who drank two to three cups a day -- 18 percent reduced chance of death"
  • Quercetin, not caffeine, is a major neuroprotective component in coffee - Neurobiol Aging. 2016 Jul 5;46:113-123 - "Epidemiologic studies indicate that coffee consumption reduces the risk of Parkinson's disease and Alzheimer's disease ... quercetin reduced oxidative/nitrative damage to DNA, as well as to the lipids and proteins of SH-SY5Y cells. There was a resultant increase in [GSH]i in SH-SY5Y cells. The data indicate that quercetin is the major neuroprotective component in coffee against Parkinson's disease and Alzheimer's disease" - See quercetin at Amazon.com.
  • Coffee consumption linked to decreased risk of colorectal cancer - Science Daily, 4/1/16 - "The data showed that even moderate coffee consumption, between one to two servings a day, was associated with a 26 percent reduction in the odds of developing colorectal cancer after adjusting for known risk factors. Moreover, the risk of developing colorectal cancer continued to decrease to up to 50 percent when participants drank more than 2.5 servings of coffee each day. The indication of decreased risk was seen across all types of coffee, both caffeinated and decaffeinated"
  • Coffee Consumption and the Risk of Cirrhosis - Medscape, 3/24/16 - "The pooled RR of cirrhosis for a daily increase in coffee consumption of two cups was 0.56"
  • Association of Coffee Consumption With Overall and Cause-specific Mortality in a Large US Prospective Cohort Study - Medscape, 12/29/15 - "Following adjustment for smoking and other potential confounders, coffee drinkers, as compared with nondrinkers, had lower hazard ratios for overall mortality (<1 cup/day: hazard ratio (HR) = 0.99 (95% confidence interval (CI): 0.92, 1.07); 1 cup/day: HR = 0.94 (95% CI: 0.87, 1.02); 2–3 cups/day: HR = 0.82 (95% CI: 0.77, 0.88); 4–5 cups/day: HR = 0.79 (95% CI: 0.72, 0.86); ≥6 cups/day: HR = 0.84 (95% CI: 0.75, 0.95)). Similar findings were observed for decaffeinated coffee and coffee additives. Inverse associations were observed for deaths from heart disease, chronic respiratory diseases, diabetes, pneumonia and influenza, and intentional self-harm, but not cancer. Coffee may reduce mortality risk by favorably affecting inflammation, lung function, insulin sensitivity, and depression"
  • Study Finds More Evidence Coffee Can Be a Life-Saver - NBC, 11/16/15 - "Non-smokers who drank coffee were between 8 and 15 percent less likely to die, depending on how much they drank ... People should also be aware of the amount of added sugar to coffee drinks which can become a problem ... The dark drink is the No. 1 source in the American diet of antioxidants - those chemical compounds that fight the damage to your DNA caused by day-to-day living ... The chlorogenic acid, lignans, quinides, trigonelline, and magnesium in coffee reduce insulin resistance and systematic inflammation"
  • Regular, Moderate Coffee Drinking Tied to Better Brain Health in Seniors - WebMD, 7/3`/`5 - "looked at the coffee consumption of 1,445 Italians aged 65 to 84. The participants' mental health was also tracked for a median of three-and-a-half years ... people who consistently drank about one or two cups of coffee per day had a lower rate of mild cognitive impairment (MCI) than those who never or rarely drank the brew ... The beneficial association was not found among people whose habitual coffee intake exceeded two cups per day"
  • Caffeine intake associated with reduced levels of erectile dysfunction - Science Daily, 5/20/15 - "Men who drink the equivalent caffeine level of two to three cups of coffee a day are less likely to have erectile dysfunction (ED) ... men who consumed between 85 and 170 milligrams of caffeine a day were 42 percent less likely to report ED, while those who drank between 171 and 303 milligrams of caffeine a day were 39 percent less likely to report ED compared to those who drank zero to seven milligrams a day ... Even though we saw a reduction in the prevalence of ED with men who were obese, overweight and hypertensive, that was not true of men with diabetes. Diabetes is one of the strongest risk factors for ED"
  • Is Your Coffee Maker Brewing Java Germs? - cbslocal.com, 5/8/15 - See the three minute video.
  • Coffee protects against breast cancer recurrence, detailed findings confirm - Science Daily, 4/21/15 - "unlike in the previous study, we have combined information about the patients' lifestyle and clinical data from 1090 breast cancer patients with studies on breast cancer cells. The study shows that among the over 500 women treated with tamoxifen, those who had drunk at least two cups of coffee a day had only half the risk of recurrence of those who drank less coffee or none at all ... Just two cups a day is sufficient to make a difference"
  • Love Coffee? Your Heart May, Too - WebMD, 3/3/15 - "drinking three to five cups a day was associated with less calcium build-up in the arteries ... Coffee contains more than 1,000 chemicals, including antioxidants that may be contributing to the health benefits"

CGA was not only effective in preventing weight gain, but it also helped maintain normal blood sugar levels and healthy liver composition ... CGA is a powerful antioxidant that reduces inflammation" - See chlorogenic acid at Amazon.com.
  • Coffee Consumption and Mortality - Medscape, 10/30/14 - "There was strong evidence of nonlinear associations between coffee consumption and mortality for all causes and CVD (P for nonlinearity < 0.001). The largest risk reductions were observed for 4 cups/day for all-cause mortality (16%, 95% confidence interval: 13, 18) and 3 cups/day for CVD mortality (21%, 95% confidence interval: 16, 26)"
  • Drinking decaf or regular coffee maybe good for the liver - Science Daily, 10/9/14 - "researchers used data from the U.S. National Health and Nutrition Examination Survey (NHANES, 1999-2010). The study population included 27,793 participants, 20 years of age or older, who provided coffee intake in a 24-hour period ... Participants who reported drinking three or more cups of coffee per day had lower levels of ALT, AST, ALP and GGT compared to those not consuming any coffee. Researchers also found low levels of these liver enzymes in participants drinking only decaffeinated coffee"
  • Impact of Coffee on Liver Diseases - Medscape, 8/14/14 - "Coffee consumption was associated with improved serum gamma glutamyltransferase, aspartate aminotransferase and alanine aminotransferase values in a dose dependent manner in individuals at risk for liver disease. In chronic liver disease patients who consume coffee, a decreased risk of progression to cirrhosis, a lowered mortality rate in cirrhosis patients, and a lowered rate of HCC development were observed. In chronic hepatitis C patients, coffee was associated with improved virologic responses to antiviral therapy. Moreover, coffee consumption was inversely related to the severity of steatohepatitis in patients with non-alcoholic fatty liver disease. Therefore, in patients with chronic liver disease, daily coffee consumption should be encouraged"
  • Coffee May Keep Your Ears From Ringing - WebMD, 8/8/14 - "Women who consumed less than 150 milligrams (mg) a day of caffeine (found in about one-and-a-half 8-ounce cups of coffee) were 15 percent more likely to develop tinnitus than those who consumed 450 mg to 599 mg a day of caffeine, the investigators found ... We know that caffeine stimulates the central nervous system, and previous research has demonstrated that caffeine has a direct effect on the inner ear in both bench science and animal studies"
  • 5 Reasons to Drink Coffee Before Your Workout - ABC News, 6/26/14 - "Improved circulation ... Less pain ... Better memory ... Muscle preservation ... Muscle preservation ... More muscle fuel"
  • Drink Up: More Coffee Could Lower Diabetes Risk - NBC News, 4/24/14 - "Researchers examined 20 years worth of data on diet, lifestyle, medical conditions and chronic diseases from three large U.S.-based observational studies and found that participants who said they increased their coffee consumption by more than a cup a day over a four year period had an 11 percent lower risk of Type 2 diabetes in the subsequent four years compared with those who made no changes in coffee consumption ... Coffee contains a multitude of compounds, such as flavonoids and magnesium, that may have a role, but it is really guess work" - [Science Daily]
  • Can Coffee Treat Liver Disease? - Medscape, 4/14/14 - "Current studies suggest that caffeine binds to adenosine receptors and reduces the development of hepatic fibrosis from liver injury by limiting stellate cell activation and the secretion of connective-tissue growth factors and collagen.[4] The diterpenes cafestol and kahweol present in coffee can increase cholesterol formation, but cafestol and kahweol are retained on paper filters during coffee brewing ... Alcohol (ethanol) consumption and cigarette smoking can increase gamma-glutamyl transferase (GGT) levels.[6] Coffee appears to reduce circulating levels of GGT ... Alcoholics who also drank coffee had a significant reduction in the risk for alcoholic cirrhosis ... Whether the effect of coffee on liver disease is related to caffeine or some other agent in coffee is not clear. However, many studies have failed to show a significant effect of other caffeine-containing drinks, such as green or black tea, on reducing fibrosis or inhibiting the development of HCC"
  • Study Links Coffee to Lower Liver Cancer Risk - WebMD, 4/9/14 - "the study started in the 1990s, researchers asked nearly 180,000 adults of different racial and ethnic backgrounds about their coffee drinking and other lifestyle habits ... tracked for as long as 18 years ... People who said they drank one to three cups of coffee a day had a 29 percent reduced risk of liver cancer compared to those who drank six cups or less each week. And more was apparently better: People who regularly had more than four cups of coffee a day had a 42 percent reduced risk ... coffee has close to 100 active compounds including antioxidants, polyphenols and caffeine. It's also known to affect liver enzymes"
  • Caffeine against Alzheimer's disease? Positive effect on tau deposits demonstrated - Science Daily, 4/7/14 - "Tau deposits, along with beta-amyloid plaques, are among the characteristic features of Alzheimer's disease. These protein deposits disrupt the communication of the nerve cells in the brain and contribute to their degeneration ... Caffeine, an adenosine receptor antagonist, blocks various receptors in the brain which are activated by adenosine"
  • It's All Coming Back to Me Now: Researchers Find Caffeine Enhances Memory - Science Daily, 1/12/14 - "The Johns Hopkins researchers conducted a double-blind trial; which participants who did not regularly eat or drink caffeinated products received either a placebo or a 200-milligram caffeine tablet five minutes after studying a series of images. Salivary samples were taken from the participants before they took the tablets to measure their caffeine levels. Samples were taken again one, three and 24 hours afterwards ... members of the caffeine group were able to correctly identify the new images as "similar" to previously viewed images versus erroneously citing them as the same ... By administering caffeine after the experiment, we rule out all of these effects and make sure that if there is an enhancement, it's due to memory and nothing else"
  • Coffee Consumption and Chronic Liver Disease - Medscape, 1/6/14 - "Sixteen studies were identified. Overall, compared with no coffee consumption, the risk for HCC was reduced by 28% with low-level consumption, and by 36% with high-level consumption (3 or more cups/day). It is likely that this favorable effect is the result of reduced cirrhosis evident in coffee drinkers, as well as improvement in the metabolic syndrome, because diabetes is another known risk factor for HCC ... There are differences in coffee bean composition as well as extractions used in preparation, but these findings seem to be specifically related to brewed, roasted, regular (not decaffeinated) coffee. Of interest, the beneficial effects have not been evident in nonfiltered, boiled (Turkish), or French press preparations ... Reportedly, there are more than 1500 chemical components of coffee, which are subject to agricultural and preparation-related influences. Although caffeine is the major active ingredient, many other components have significant antioxidant activity"
  • Coffee May Help Perk Up Your Blood Vessels - Science Daily, 11/20/13 - "A study of 27 healthy adults showed -- for the first time -- that drinking a cup of caffeinated coffee significantly improved blood flow in a finger, which is a measure of how well the inner lining of the body's smaller blood vessels work. Specifically, participants who drank a cup of caffeinated coffee had a 30 percent increase in blood flow over a 75-minute period compared to those who drank decaffeinated coffee"
  • Coffee consumption reduces risk of liver cancer, analysis suggests - Science Daily, 10/22/13 - "Coffee consumption reduces risk of hepatocellular carcinoma (HCC), the most common type of liver cancer, by about 40 percent ... some data indicate that three cups of coffee per day reduce liver cancer risk by more than 50 percent ... The favorable effect of coffee on liver cancer might be mediated by coffee's proven prevention of diabetes, a known risk factor for the disease, or for its beneficial effects on cirrhosis and liver enzymes ... a meta-analysis of articles published from 1996 through September 2012, ultimately studying 16 high-quality studies and a total of 3,153 cases"
  • Four or more cups of coffee a day may keep prostate cancer recurrence and progression away - Science Daily, 8/26/13 - "men who drank four or more cups of coffee per day experienced a 59 percent reduced risk of prostate cancer recurrence and/or progression as compared to those who drank only one or fewer cups per week ... the researchers did not find an associated reduction of prostate cancer recurrence and/or progression. The study also did not draw any conclusions regarding the impact of tea drinking on prostate-specific death ... The population-based study involved 1,001 prostate cancer survivors, aged 35-74 years old at the time of diagnosis between 2002-2005, who were residents of King County, Wash ... biological activities associated with consumption of phytochemical compounds found in coffee include anti-inflammatory and antioxidant effects and modulation of glucose metabolism"
  • Coffee and tea may contribute to a healthy liver - Science Daily, 8/16/13 - "increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD) ... caffeine stimulates the metabolization of lipids stored in liver cells and decreased the fatty liver of mice that were fed a high-fat diet. These findings suggest that consuming the equivalent caffeine intake of four cups of coffee or tea a day may be beneficial in preventing and protecting against the progression of NAFLD in humans"
  • More than 28 cups of coffee a week may endanger health in under 55s - Science Daily, 8/15/13 - "A study of more than 40,000 individuals found a statistically significant 21% increased mortality in those drinking more than 28 cups of coffee a week and death from all causes, with a greater than 50% increased mortality risk in both men and women younger than 55 years of age ... No adverse effects were found in heavy coffee drinkers aged over 55 ... Between 1979 and 1998, nearly 45,000 individuals aged between 20 and 87 years old participated and returned a medical history questionnaire assessing lifestyle habits (including coffee consumption) and personal and family medical history ... Those who consumed higher amounts of coffee (both men and women) were more likely to smoke and had lower levels of cardiorespiratory fitness" - Note:  It doesn't say whether the results were adjusted for the smoking so maybe that was the real cause.
  • The Effect of Coffee Consumption on the Development of HCC - Medscape, 8/12/13 - "a high lifetime coffee consumption (≥20 000 cups) was an independent protective factor against HCC, in each analyses using healthy and risky control groups respectively (HCE group, OR 0.56, 95% CI 0.33–0.95; CLD group, OR 0.55, 95% CI 0.36–0.85). However, the high coffee consumption did not affect the HCC risk in patients with HBV (OR 0.64, 95% CI 0.36–1.14) after adjustment for HBeAg status, serum HBV DNA level and antiviral therapy"
  • Tea and Coffee Lower Blood Pressure - Medscape, 6/18/13 - "After adjustments that included these and other potential confounding variables, both coffee and tea consumption was associated with a significant reduction in systolic and diastolic blood pressure, as well as other variables" - See the table.  For coffee, no coffee was 127.9 for none, 1 - 4 cups was 126.7 and > 4 cups was 125.5 on the systolic.
  • This Is Your Brain on Coffee - NYTimes.com, 6/6/13 - "In one large-scale epidemiological study from last year, researchers primarily at the National Cancer Institute parsed health information from more than 400,000 volunteers, ages 50 to 71, who were free of major diseases at the study’s start in 1995. By 2008, more than 50,000 of the participants had died. But men who reported drinking two or three cups of coffee a day were 10 percent less likely to have died than those who didn’t drink coffee, while women drinking the same amount had 13 percent less risk of dying during the study ... animal experiments show that caffeine may reshape the biochemical environment inside our brains in ways that could stave off dementia ... Close examination of the animals’ brain tissue showed that the caffeine disrupted the action of adenosine, a substance inside cells that usually provides energy, but can become destructive if it leaks out when the cells are injured or under stress ... Participants with little or no caffeine circulating in their bloodstreams were far more likely to have progressed to full-blown Alzheimer’s than those whose blood indicated they’d had about three cups’ worth of caffeine"
  • Coffee may help prevent breast cancer returning, study finds - Science Daily, 4/25/13 - "Patients who took the pill, along with two or more cups of coffee daily, reported less than half the rate of cancer recurrence, compared with their Tamoxifen-taking counterparts who drank one cup or less ... One theory we are working with is that coffee 'activates' Tamoxifen and makes it more efficient"
  • Coffee Consumption and Risk of Liver Cancer - Medscape, 4/22/13 - "searched Medline, EMBASE, ISI Web of Science and the Cochrane library for studies published up to May 2012 ... The summary odds ratio (OR) for high vs no/almost never drinkers was 0.50 (95% confidence interval (CI): 0.42–0.59), with no significant heterogeneity across studies (Q = 16.71; P = 0.337; I2 = 10.2%). The ORs were 0.50 (95% CI: 0.40–0.63) for case–control studies and 0.48 (95% CI: 0.38–0.62) for cohort studies. The OR was 0.38 (95% CI: 0.25–0.56) in males and 0.60 (95% CI: 0.33–1.10) in females. The OR was 0.45 (95% CI: 0.36–0.56) in Asian studies and 0.57 (95% CI: 0.44–0.75) in European studies. The OR was 0.39 (95% CI: 0.28–0.54) with no adjustment for a history of liver disease and 0.54 (95% CI: 0.46–0.66) after adjustment for a history of liver disease"
  • Safety: Caffeine Leads to Fewer Driving Accidents - NYTimes.com, 3/21/13 - "After adjusting for age, driver experience, distance driven, hours of sleep, naps, night driving and other factors, they found that drivers who consumed caffeine were 63 percent less likely to be involved in a crash"
  • Coffee and Green Tea May Help Lower Stroke Risk - WebMD, 3/15/13 - "The study looked at the green tea and coffee drinking habits of more than 82,000 Japanese adults, ages 45 to 74, for an average of 13 years ... People who drank at least 1 cup of coffee daily had about a 20% lower risk of stroke compared to those who rarely drank it ... People who drank 2 to 3 cups of green tea daily had a 14% lower risk of stroke, and those who had at least 4 cups had a 20% lower risk, compared to those who rarely drank it ... People who drank at least 1 cup of coffee or 2 cups of green tea daily had a 32% lower risk of intracerebral hemorrhage, compared to those who rarely drank either beverage. Intracerebral hemorrhage happens when a blood vessel bursts and bleeds inside the brain. About 13% of strokes are due to this condition ... Some chemicals in coffee include chlorogenic acid, which is thought to cut stroke risks by lowering the chances of developing type 2 diabetes" - [Abstract] - Note:  Chlorogenic acid is in fruit extracts such as blueberry extract.  See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com.
  • Coffee and tea during pregnancy affect fetal growth - Science Daily, 3/11/13 - "study on 59,000 women in collaboration with the Norwegian Institute of Public Health ... The correlation between intake of caffeine and fetal growth was established even among women who followed the official recommendation that they limit caffeine consumption to 200 milligrams a day (two cups of coffee)"
  • Caffeine linked to low birth weight babies - Science Daily, 2/18/13 - "small for gestational age at birth (SGA). In this study we found no association between either total caffeine or coffee caffeine and preterm delivery but we did find an association between caffeine and SGA ... caffeine from all sources reduced birth weight. For a child of expected average weight (3.6kg) this equates to 21-28g lost per 100mg caffeine per day. But it was not just caffeine, but the source of caffeine, which affected pregnancy outcomes. Caffeine from all sources increased the length of the pregnancy by 5hr per 100mg caffeine per day, but caffeine intake from coffee was associated with an even longer gestational length -- 8hr extra for every 100mg caffeine per day ... SGA babies are at higher risk of both short term and lifelong health problems and it seems from these results that since even 200-300mg caffeine per day can increase the risk of SGA by almost a third these recommendations need to be re-evaluated"
  • Coffee, Tea, and Fatal Oral/Pharyngeal Cancer - Medscape, 2/1/13 - "Intake of >4 cups/day of caffeinated coffee was associated with a 49% lower risk of oral/pharyngeal cancer death relative to no/occasional coffee intake (relative risk = 0.51, 95% confidence interval: 0.40, 0.64) (1 cup/day = 237 ml). A dose-related decline in relative risk was observed with each single cup/day consumed (P trend < 0.001). The association was not modified by sex, smoking status, or alcohol use. An inverse association for >2 cups/day of decaffeinated coffee intake was suggested (relative risk = 0.61, 95% confidence interval: 0.37, 1.01). No association was found for tea drinking. In this large prospective study, caffeinated coffee intake was inversely associated with oral/pharyngeal cancer mortality. Research is needed to elucidate biologic mechanisms whereby coffee might help to protect against these often fatal cancers"
  • Caffeinated coffee may reduce the risk of oral cancers - Science Daily, 12/10/12 - "Cancer Prevention Study II, a prospective U.S. cohort study begun in 1982 by the American Cancer Society ... 26 years of follow-up ... consuming more than four cups of caffeinated coffee per day was associated with a 49 percent lower risk of oral/pharyngeal cancer death relative to no/occasional coffee intake (RR 0.51, 95% confidence interval [CI] 0.40-0.64). A dose-related decline in relative risk was observed with each single cup per day consumed ... Coffee is one of the most widely consumed beverages in the world, and contains a variety of antioxidants, polyphenols, and other biologically active compounds that may help to protect against development or progression of cancers"
  • Moderate coffee consumption may reduce risk of diabetes by up to 25 percent - Science Daily, 12/4/12 - "Drinking three to four cups of coffee per day may help to prevent type 2 diabetes according to research highlighted in a session report published by the Institute for Scientific Information on Coffee (ISIC), a not-for-profit organization devoted to the study and disclosure of science related to coffee and health ... The report outlines the epidemiological evidence linking coffee consumption to diabetes prevention, highlighting research that shows three to four cups of coffee per day is associated with an approximate 25 per cent lower risk of developing type 2 diabetes, compared to consuming none or less than two cups per day1. Another study also found an inverse dose dependent response effect with each additional cup of coffee reducing the relative risk by 7-8 per cent"
  • Caffeine may block inflammation linked to mild cognitive impairment - Science Daily, 10/8/12 - "Freund's team examined the effects of caffeine on memory formation in two groups of mice -- one group given caffeine, the other receiving none. The two groups were then exposed to hypoxia, simulating what happens in the brain during an interruption of breathing or blood flow, and then allowed to recover ... The caffeine-treated mice recovered their ability to form a new memory 33 percent faster than the non-caffeine-treated mice. In fact, caffeine had the same anti-inflammatory effect as blocking IL-1 signaling. IL-1 is a critical player in the inflammation associated with many neurodegenerative diseases ... caffeine blocks all the activity of adenosine and inhibits caspase-1 and the inflammation that comes with it, limiting damage to the brain and protecting it from further injury"
  • Drinking coffee may reduce risk of most common form of skin cancer - Science Daily, 7/2/12 - "Our data indicate that the more caffeinated coffee you consume, the lower your risk of developing basal cell carcinoma ... Basal cell carcinoma is the form of skin cancer most commonly diagnosed in the United States. Even though it is slow-growing, it causes considerable morbidity and places a burden on health care systems ... Of the 112,897 participants included in the analyses, 22,786 developed basal cell carcinoma during the more than 20 years of follow-up in the two studies. An inverse association was observed between all coffee consumption and risk of basal cell carcinoma. Similarly, an inverse association was seen between intake of caffeine from all dietary sources (coffee, tea, cola and chocolate) and risk of basal cell carcinoma. However, consumption of decaffeinated coffee was not associated with a decreased risk of basal cell carcinoma ... In contrast to the findings for basal cell carcinoma, neither coffee consumption nor caffeine intake were inversely associated with the two other forms of skin cancer, squamous cell carcinoma and melanoma, the most deadly form of the disease"
  • Caffeine boosts power for elderly muscles - Science Daily, 6/29/12 - "For adults in their prime, caffeine helps muscles to produce more force ... With the importance of maintaining a physically active lifestyle to preserve health and functional capacity, the performance-enhancing benefit of caffeine could prove beneficial in the aging population"
  • High blood caffeine levels in older adults linked to avoidance of Alzheimer’s disease - Science Daily, 6/4/12 - "The collaborative study involved 124 people, ages 65 to 88, in Tampa and Miami ... These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee -- about 3 cups a day -- will not convert to Alzheimer's disease -- or at least will experience a substantial delay before converting to Alzheimer's ... The results from this study, along with our earlier studies in Alzheimer's mice, are very consistent in indicating that moderate daily caffeine/coffee intake throughout adulthood should appreciably protect against Alzheimer's disease later in life ... We found that 100 percent of the MCI patients with plasma caffeine levels above the critical level experienced no conversion to Alzheimer's disease during the two-to-four year follow-up period ... In addition to Alzheimer's disease, moderate caffeine/coffee intake appears to reduce the risk of several other diseases of aging, including Parkinson's disease, stroke, Type II diabetes, and breast cancer"
  • Coffee May Be Part of the Recipe for a Longer Life - WebMD, 5/16/12 - "The study, described as the largest of its kind, found that coffee drinkers had a lower risk of death from heart disease, respiratory disease, stroke, accidents and injuries, diabetes, and infections, but not from cancer ... Compared to people who drank no coffee, coffee drinkers who downed three or more cups a day had about a 10% lower risk of death overall and a lower risk of dying from each of a variety of leading killers. Cancer was the only exception .. Among women, coffee drinkers and non-drinkers were equally likely to die of cancer. Among men, there was only a slight connection between heavier coffee drinking and increased risk of dying from cancer ... Although their study can't prove that coffee itself lowers drinkers' risk of dying, Freedman and his colleagues speculate about how it might. Caffeine probably is not a factor, he says, because death rates linked to decaf, preferred by a third of the coffee drinkers, were similar to those associated with caffeinated. But other compounds in coffee, such as antioxidants, might be important, the researchers write"
  • Coffee Bean Extract Linked to Weight Loss - ABC News, 3/27/12 - "Researchers gave up to 1,050 milligrams of green coffee bean extract to 16 overweight adults in their 20s and monitored their diet, exercise regimen, weight, heart rate and blood pressure for 22 weeks. Without changing their diet or exercise, study subjects lost roughly 10.5 percent — an average of 17 pounds – in overall body weight. No harmful side effects were noted ... How green coffee bean extract contributes to weight loss is unclear. But Vinson theorizes a chemical in the unroasted bean called chlorogenic acid could be responsible" - See green coffee bean extract at Amazon.com.
  • Coffee poses no threat to hearts, may reduce diabetes risk: EPIC data - Nutra USA, 3/19/12 - "There was no link between coffee consumption and the incidence of heart disease, nor the risk of cancer" - [Abstract]
  • Exercise and caffeine change your DNA in the same way, study suggests - Science Daily, 3/6/12 - "when healthy but inactive men and women exercise for a matter of minutes, it produces a rather immediate change to their DNA. Perhaps even more tantalizing, the study suggests that the caffeine in your morning coffee might also influence muscle in essentially the same way ... for those who can't exercise, the new findings might point the way to medicines (caffeinated ones, perhaps?) with similar benefits"
  • 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 ...

  • 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 ...

  • 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"

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"

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"
  • Coffee Consumption and Mortality Due to All Causes, Cardiovascular Disease, and Cancer in Japanese Women - J Nutr. 2010 Mar 24 - "In women, the multivariate hazard ratios (HR) (95% CI) for all-cause mortality in participants who drank coffee never, occasionally, 1-2 cups (150-300 mL)/d, and >/=3 cups/d were 1.00, 0.88 (0.73-1.06), 0.82 (0.66-1.02), and 0.75 (0.53-1.05), respectively (P-trend = 0.04). For CVD mortality in women, the multivariate HR (95% CI) were 1.00, 0.56 (0.36-0.86), 0.48 (0.29-0.80), and 0.45 (0.20-1.03), respectively (P-trend = 0.006). Of the specific CVD diseases, there was a strong inverse association between coffee consumption and mortality due to coronary heart disease (CHD) in women (P-trend = 0.02) but not in men. Death due to cancer was not associated with coffee consumption in either men or women, except for colorectal cancer in women. Our results suggest that coffee may have favorable effects on morality due to all causes and to CVD, especially CHD, in women"

  • Acute effects of coffee on endothelial function in healthy subjects - Eur J Clin Nutr. 2010 Feb - "caffeinated (CC) and one cup of decaffeinated (DC) Italian espresso coffee ... Subjects ingested one cup of caffeinated (CC) and one cup of decaffeinated (DC) Italian espresso coffee in random order at 5- to 7-day intervals.Results:Following CC ingestion, FMD decreased progressively and significantly (mean+/-s.e.m.: 0 min, 7.7+/-0.6; 30 min, 6.3+/-0.7; 60 min, 6.0+/-0.8%; ANOVA (analysis of variance), P<0.05), but it did not significantly increase after DC ingestion (0 min, 6.9+/-0.6; 30 min, 8.1+/-0.9; 60 min, 8.5+/-0.9%; P=0.115). Similarly, CC significantly increased both systolic and diastolic blood pressure; this effect was not observed after DC ingestion. Blood glucose concentrations remained unchanged after ingestion of both CC and DC, but insulin (0 min, 15.8+/-0.9; 60 min, 15.0+/-0.8 muU/ml; P<0.05) and C-peptide (0 min, 1.25+/-0.09; 60 min, 1.18+/-0.09 ng/ml; P<0.01) blood concentrations decreased significantly only after CC ingestion.Conclusions:CC acutely induced unfavorable cardiovascular effects, especially on endothelial function. In the fasting state, insulin secretion is also likely reduced after CC ingestion"
