“I keep getting confused” How many cups of coffee should I drink a day?… ‘This much’ is best

Various claims about the health effects of caffeine in coffee confuse people. Some studies have shown that consuming caffeine can help improve blood vessel health and lower the risk of type 2 diabetes, while others have shown that consuming too much caffeine can increase the risk of stroke.

‘Medical News Today’, a health media outlet, collected and introduced the latest research results on coffee and the heart and also provided guidance on appropriate coffee consumption. Worldwide, approximately one in seven people die from coronary heart disease. For this reason, the cardioprotective effects of coffee are an interesting topic.

On the 9th of last month, a study was published in the journal ‘Rheumatology’ showing that consuming a lot of caffeine found in coffee, tea, cocoa, etc. can help improve blood vessel health. This study attracted attention because it was conducted on patients with lupus, an autoimmune disease with a high risk of stroke, heart attack, and cardiovascular disease.

A study published last September in the journal Endocrinology and Metabolism found that regular, moderate consumption of coffee and caffeine may help prevent conditions such as type 2 diabetes, coronary heart disease, and stroke. Researchers found that consuming about 200 to 300 mg (about 2 to 3 cups of coffee) every day was most effective.

Researchers compared people who consumed about 200 to 300 mg of caffeine per day with people who consumed no caffeine or less than 100 mg per day. The latter reduced the risk of heart disease by 40% and the risk of metabolic disease by 48%.

“Caffeine enhances insulin sensitivity and promotes fat metabolism, which supports overall cardio-metabolic health,” says nutritionist Melanie Murphy Richter. “Coffee and tea are complex beverages containing hundreds of bioactive compounds, and their biological effects likely extend beyond those of caffeine itself,” said cardiologist Dr Chen Chenghan. “Compounds such as flavonoids, alkaloids and polyphenols are known to have antioxidant and anti-inflammatory effects and may also be involved in glucose and lipid metabolism.” “

A study published last August found that people who chronically consume high doses of caffeine at least five days a week may have an increased risk of cardiovascular disease. Researchers defined chronic caffeine consumption as drinking all caffeinated beverages, including coffee, tea, soda, and energy drinks, five days a week for more than one year. This is approximately 400 mg of caffeine, or the equivalent of 4 cups of coffee, 2 energy drinks, or 10 cans of soda.

Researchers found that people who consumed 400 mg per day had higher heart rates and blood pressure over time, and this was even more pronounced for those who consumed 600 mg per day.

“Caffeine can affect the autonomic nervous system, putting healthy people at risk for high blood pressure and other cardiovascular diseases,” said Nenshi Kagatra, a researcher at Zydus Medical Center in India and lead author of the study.

A study published last September found that drinking too much soda, fruit juice and drinks, and coffee may increase the risk of stroke and intracerebral hemorrhage. Researchers found that drinking three to four cups of black tea a day lowered the risk of stroke by 29%. This effect appeared differently depending on where people lived. Drinking four or more cups of coffee every day increased your risk of having a stroke by 37%. Drinking less than four drinks was not associated with an increased risk of stroke.
