IT’S PROVEN: 3 TO 4 CUPS OF COFFEE A DAY CAN EXTEND YOUR SHELF LIFE
Tea ( green tea or black tea ) or coffee , these drinks are the daily companions of many people in the world, as much for their benefits, their effects, as for their potential taste. This consumption may not be eternal. Let’s enjoy and respect these plants as much as possible, since, especially for coffee, a risk of shortage due to climate change is likely to arrive by 2050, according to many experts gathered during the first World Forum of Coffee Producing Countries in 2017.
To remain positive, and while waiting to find solutions to stop climate change (hope for this outcome), a meta-analysis, published on November 22, 2017 in the journal BMJ , reveals that the consumption of three or four cups per day confers the greater benefit to health, except during pregnancy and for women at risk of fracture. Drinking coffee is more likely to benefit health than harm, and this for a series of obvious health outcomes.
I LIKE YOUR COFFEE COLOR
As can be seen, studies are published regularly on coffee. It is therefore commendable to ask whether these studies are still objective and not only initiated by companies related to the coffee and coffee products business.
This new study is a meta-analysis, which allows for a wider range of results. She collects evidence from more than 200 studies and finds that drinking three to four cups of coffee a day is associated with a lower risk of death and heart disease compared to not drinking coffee. Coffee consumption is also associated with a lower risk of certain cancers, diabetes, liver disease and dementia.
However, researchers say that drinking coffee during pregnancy may be associated with injury, and may be related to a very small increased risk of fracture in women.
The studies analyzed in this meta-analysis used mainly observational data, sometimes providing lower quality evidence, so that no definitive conclusions can be drawn about the cause and effect, but their results support other recent studies. on the coffee intake. As such, researchers say that, (excluding pregnancy and women at risk of fracture), drinking coffee seems safe in consumer habits and they suggest that coffee could be tested safely in randomized trials .
To better understand the effects of coffee consumption on health, a team of public health specialists at the University of Southampton , with staff from the University of Edinburgh in the UK, conducted a general review of 201 data-gathering studies, observational research and 17 studies that aggregated data from clinical trials in all countries and all settings.
3 CUPS OF COFFEE A DAY IS ENOUGH
Coffee consumption is consistently associated with a lower risk of all-cause death and heart disease, with the greatest reduction in the relative risk of death being three cups per day compared to non-coffee drinkers. Increasing consumption to more than three cups a day isn’t associated with damage, but the beneficial effect is less pronounced.
Coffee is also associated with a lower risk of several cancers, including prostate, endometrial, skin and liver, as well as type 2 diabetes , gallstones and gout. The greatest benefit has been observed for liver diseases, such as cirrhosis of the liver.
Finally, there seem to be beneficial associations between coffee consumption and Parkinson’s disease, depression and Alzheimer’s disease . There was less evidence on the effects of drinking decaffeinated coffee, but it had similar benefits for a number of outcomes.
Many of the studies may have been adjusted for factors that may be associated with both health outcome and coffee consumption, such as smoking. It was not complete and varied from one study to another. The authors can not, therefore, exclude the effect of such factors on apparently harmful or beneficial associations. The authors conclude that drinking coffee seems safe in drinking patterns, except during pregnancy and in women at increased risk of fracture. And they call for robust randomized controlled trials to understand if the key associations observed are causal.
While these results are motivating, as long as we can not be sure that coffee is generally ” good for you ,” doctors or other health professionals should not recommend drinking coffee to prevent illness.
As this study shows, some people may be at greater risk for adverse effects. There is substantial uncertainty about the effects of higher levels of consumption. Finally, coffee is often consumed with products rich in refined sugars and unhealthy fats, and these can contribute independently to adverse health effects. But what idea to drink coffee with sugar?
However, the researchers indicate that even with these warnings, moderate coffee consumption seems remarkably safe, and it can be incorporated as part of a healthy and balanced diet by the majority of the adult population.
