Coffee is a highly complex agricultural product packed with all sorts of beneficial compounds.
These studies also show that benefits are present in the same level for regular and decaf. as well as water type and temperature) or brew ratio (grams of coffee to water).Īndrew Salisbury, CEO of Purity Coffee, says, “Coffee is good for you, and we now know coffee is much more than just a caffeine delivery system.
In both this and other research on coffee, further work needs to be done to create a standard for roast curve (how heat is applied to the coffee and how fast the coffee is roasted), roast level (how light or dark the beans are), brew method (espresso, filter, French-press, etc. The earlier European study state, though, that results did not vary by country where coffee preparation and drinking habits may differ. The Yamakawa research acknowledges that it did not standardize its ‘cup of coffee.’ In other words, some subjects may have been brewing a weak filter coffee and others a strong espresso-type extraction. Interestingly, both the Japanese and European studies reported relationships between coffee drinking and lower mortality from digestive diseases. In 2015, a study with 133,000 subjects showed 3-5 cups a day reduced risk of all-cause mortality by 15% in 10 European countries and half a million subjects, research showed a decrease around 12%, and in 2017 a study among non-white populations showed 2-3 cups decreased all cause mortality by 18%. They all show the association of coffee and lower risk of mortality from all causes over a similar period of time. This study has similar findings of other large population studies throughout several countries that have been published over the past 4 years. Subjects who drank 2-3 cups of coffee a day showed highest results at 19% lower risk. The “Takayama study”, by Michiyo Yamakawa and others, tracked over 31,500 people for more than 14 years, and showed that even one cup of coffee was associated with a 16% lower risk of all-cause mortality and mortality from cardiovascular, infectious and digestive diseases. Even one cup of coffee a day can help you live longer, according to a new Japanese study on coffee and mortality.
