Research resources on health, diet fitness and ageing

We created this page to provide unbiased research, not just opinions on popular topics. It is an ongoing project.

  1. Should humans drink coffee?

Studies that says YES:

  1.  A meta analysis of twenty studies of coffee consumption and total mortality, including 129,538 cases of deaths among the 973,904 participants. The findings indicate that coffee consumption is associated with a reduced risk of total mortality
  2. Genetic polymorphism that affects caffeine metabolism was studied here. Coffee drinking was inversely associated with mortality, including among those drinking 8 or more cups per day and those with genetic polymorphisms indicating slower or faster caffeine metabolism. These findings suggest the importance of noncaffeine constituents in the coffee-mortality association and provide further reassurance that coffee drinking can be a part of a healthy diet.
  3. Results in this study suggested that both regular and decaffeinated coffee consumption have effects on aging and age-related diseases such as cancer by decreasing mTOR
  4. The findings here do not support the hypothesis from some researchers that coffee consumption increases the long-term risk of coronary heart disease. Habitual moderate coffee drinking was associated with a lower risk of CHD in women.

Studies that says maybe not:

  1. Narrative reviews have concluded that there is a small association between coffee consumption and an increased risk of urinary tract cancer, possibly due to confounding by smoking.
  2. The results from this meta-analysis of observational studies demonstrate that coffee consumption would increase the laryngeal cancer risk, while tea intake was not associated with risk of laryngeal carcinoma.

Conclusion:

Decide for yourself by reading through the above. But overall, it seems to be good, even very good for humans. Drinking coffee with sugar, cream or milk is not discussed here.
