How many cups of coffee should you drink a day, according to ‘science’

Studies that are now in the news show that people who drink two to three cups of coffee a day live longer than those who don’t drink coffee. So should we all have a couple of drinks? Not necessarily. Let’s see where these numbers come from.

Maybe 2-3 cups for longevity

this Recent research The average age is 58 years old, and just over half of the participants are female. About 95% CaucasianResearchers were able to follow participants for an average of 12 years after they answered questions about their coffee intake.

When looking at all-cause mortality, people who drank two to three cups of coffee a day had the lowest risk, even if they drank ground, instant, or decaffeinated coffee.For cardiovascular disease, those who drank one cup a day had the lowest risk, but for arrhythmia (irregular heartbeat), the sweet spot appeared to be four to five cups. coffee without No It helps reduce risk.

However, the study has a number of limitations if you are trying to figure out how much coffee you drink using this study. There is a possibility. People don’t randomly decide how much coffee to drink.Income, social class and perceived health risks, to name just a few, may contribute to that choice (British people also tend to drink a lot instant coffee and espresso, it turns out). The researchers also took people’s self-reported data at face value and assumed they drank the same amount of coffee over the years, rather than continually reassessing it.

3-4 scoops for other health benefits

a Review published in BMJ It looked at dozens of previous studies on coffee and concluded that coffee drinkers have a lower risk of cardiovascular disease, including stroke, some cancers, and some liver and gastrointestinal disorders. The amount of coffee associated with was often in the range of 3-4 cups per day.

author of the analysis Said what people shouldn’t do start I wouldn’t drink coffee for these results, but if you’re already drinking coffee, it “can be part of a healthy diet.”

Part of the reason it’s so hard to figure out what’s going on with coffee is that coffee has hundreds of different bioactive compounds, and caffeine is just one of them. It can also vary depending on which beans you start with and how you prepare your coffee.

But another reason is that these studies don’t randomly assign people to drink coffee or not.They’re usually just surveying people about how much coffee they drink already to drink. If your doctor tells you to limit caffeine because of your blood pressure, for example, you will appear in studies as a non-coffee drinker. It may have associated risk factors, which are not always reflected in research.

“Robust randomizationControlled trials are needed to understand whether the observed associations are causal. [i.e., caused by coffee]’” concludes the author.

4 cups or less to be safe

of U.S. Dietary Guidelines Regarding coffee consumption in non-pregnant adults, “FDA lists 400 milligrams of caffeine per day for healthy adults as an amount generally not associated with dangerous adverse effects.” 200 milligrams is Recommended limits during pregnancy.)

In other words, coffee is not so important to health that everyone is encouraged to drink it. Instead, they specify an amount that is basically okay.

So how much coffee is that? Most freshly brewed coffee has about 100 milligrams per 8 fl oz. This varies considerably by brand and brewing style. For example, a 14 ounce Dunkin’ brewed coffee has 210 milligrams. A 16 ounce McDonald’s coffee has 145 caffeine. caffeine informant.

One thing before ordering: THis guidelines also point out that sweetened coffee drinks are one common source of sugar in the diet. Added sugar should be kept to less than 10% of his total calories, or about 50 grams. Starbucks iced coffee is 20 grams. Caramel FRappuccino is 54. Black coffee, on the other hand, is basically zero.
