Coffee may have health benefits, but we're still figuring out how much is enough.
According to a study that is now making headlines, those who consume a couple cups of coffee every day live longer than those who don't. So, would it be wise for us to each have a few glasses to drink? Actually, no. We should look into the source of these figures.
Maybe a few cups for longevity
This new study is based on data from the UK Biobank, whose members are typically 95% white, average 58 years old, and lean more toward women than men. After asking participants how much espresso they consume, the experts generally had the ability to follow them for a considerable amount of time.
If we consider death from all causes, those who drank a couple cups of espresso daily had the lowest risk, and this is true whether they drank ground, instant, or decaf. One cup per day drinkers had the lowest risk of cardiovascular disease, but for arrhythmia (sporadic heartbeat), four to five cups seemed to be the ideal amount. Decaf espresso was not associated with a lower risk in the arrhythmia outcomes.
However, if you're trying to use the review to determine how much espresso to drink, it has a lot of limitations. This group of middle-aged English people may not be able to communicate with the rest of the world very effectively, and they despise people who carelessly choose how much coffee to consume. Pay, social class, and health risks that were observed, to name a few, can influence that choice (Brits likewise will generally drink a ton of moment espresso and coffee, it ends up). The experts also had complete faith in what people self-reported, and they anticipated that they would consume the same amount of coffee throughout time rather than periodically reassessing.
For further wellness effects, drink three to four cups.
A study published An the BMJ looked at numerous prior studies on coffee consumption and hypothesized that those who consume coffee have decreased risks of cardiovascular diseases, including strokes, some malignant growths, and some liver and gastrointestinal problems. The amount of espresso associated with lowered risk was frequently three to four cups per day.
Because of these findings, the study's author advised people not to start drinking coffee, but said that if you already do, it "may be beneficial for a sound dietary routine."
The authors conclude, "Strong randomized controlled preliminary studies are expected to understand whether the noticed associations are causal [i.e., caused by coffee]."
Four cups or fewer, to be protected
The U.S. Dietary Guidelines only state the following on adult non-pregnant individuals' use of espresso: "For healthy adults, the FDA has referred to 400 milligrams of caffeine per day as an amount not often associated with hazardous, unfavorable effects." (In pregnancy, 200 mg is the maximum permissible dose.)
Overall, they don't recommend that everyone drink espresso because it isn't very vital to health. On the other hand, it's not so dangerous that there is a clear breaking point. All things considered, they specify a sum that is generally acceptable. (Extremely large doses of caffeine would probably be bad. They can say with confidence that this amount is not particularly large.)
What quantity of espresso is that? For every 8 liquid ounces, the majority of prepared espresso contains close to 100 mg. According to brand and fermentation method, this varies considerably. For instance, a 16-ounce McDonald's espresso has 145 mg, whereas a 14-ounce Dunkin' blended espresso has 210. You can check the amount of caffeine in your number.

However, before you ask: The guidelines also point out the fact that enhanced espresso beverages are one of the typical sources of added sugars in the diet. Under 10% of our total daily calories, or about 50 grams, should be allocated to added sugars. Starbucks' cold espresso has 20 grams, while their caramel Frappuccino has 54. Dark espresso, on the other hand, has virtually none.
