How many cups of coffee are you allowed to drink per day?

(Dan Tri) - According to data from the National Coffee Association of America, two-thirds of Americans drink coffee every day. And the debate about how much coffee is enough continues.

Is drinking 2 to 3 cups of coffee a day too much?

A Harvard study, which tracked nearly 50,000 women for 30 years and was published in June, found that drinking coffee daily may help women age healthier. Drinking 1-3 cups a day was also associated with cardiovascular health benefits and reduced mortality rates.

However, research also indicates that consuming large amounts of coffee may increase the risk of dementia. A 2022 paper published in the Journal of the American Heart Association found a link between high coffee consumption and the risk of death from cardiovascular disease in people with hypertension.

The benefits, drawbacks, and appropriate dosage all depend on your individual lifestyle and overall health. And health experts always advise that, like most things, it's important to drink coffee in moderation each day.

You should keep your caffeine intake at 400mg per day or less.

Deepak Chopra, a speaker and advocate for alternative medicine, shared with CNBC Make It that he drinks 2-3 cups of coffee a day before noon. While this might sound like a lot of caffeine for the average person, it's actually still within a healthy range.

"Drinking two to three cups of coffee before noon is safe, as long as they don't exceed 400mg of caffeine," says nutritionist Roxana Ehsani.

Ehsani's advice follows the U.S. Food and Drug Administration's (FDA) recommendation to consume no more than 400mg of caffeine per day, including caffeine found in tea, energy drinks, soda, and chocolate.

Advice from the experts

It's important to consider your individual experience. Some people may benefit from consuming significantly less caffeine than the FDA recommends.

Caffeine tolerance varies from person to person; some people experience anxiety or restlessness after just one or two cups of coffee.

"Within the recommended range of milligrams or a cup of coffee, if you start feeling excessively tired and the caffeine isn't working, then you have to stop. If your heart starts beating extremely fast, you have to stop. Everyone is different," nutritionist Jessica Sylvester told NBC News .

Nutrition expert Nikki Cota of the Mayo Clinic adds that pregnant women should consider cutting back on caffeine. Those with diabetes or cardiovascular disease should be mindful of their sugar intake when drinking coffee.

Experts also have differing opinions on whether teenagers should drink coffee, but according to the American Academy of Pediatrics, avoiding caffeine is the best option for all children.

For others, experts advise that if you drink 2-3 cups of coffee or more, be mindful of how you feel and make sure you're not replacing meals with caffeine. You should drink water or eat before drinking coffee because caffeine reduces appetite.

And if you find that your sleep is affected when you drink coffee in the afternoon, experts recommend that you only have lattes or macchiatos in the morning.

Similarly, Dr. Phung Tuan Giang, Chairman of the Vietnam Institute for Research and Development of Traditional Medicine, stated that coffee seems to be a double-edged sword. It can make us feel more alert, productive, and motivated.

However, for some people, it has the opposite effect, making them feel anxious, restless, and unable to concentrate.

In fact, coffee is also rich in antioxidants and contains small amounts of some micronutrients that our bodies need.

"In moderation, most people can safely enjoy coffee as part of a healthy diet. However, there are some people who should not consume caffeine," Dr. Giang noted.

For example, children are advised to avoid coffee because it can affect their growth and development. Coffee can cause insomnia, so those who have trouble sleeping should limit their consumption, especially avoiding coffee in the evening.

Pregnant women should also limit their caffeine intake to less than 200mg per day. You should also avoid consuming more than 500mg of caffeine per day, which is about 5 regular cups of coffee.

Therefore , experts agree that as long as you don't experience any unpleasant side effects and you drink it in moderation, coffee is a perfectly fine beverage to enjoy…
