Is coffee the healthiest? Choose tea or coffee

A new study lists the health benefits of coffee and tea, which can help reduce diabetes, heart disease and cancer and help prevent obesity.

Studies have shown that people who drink black tea four times a day for six weeks have significantly lower levels of the stress hormone cortisol. But if milk is added to the tea, it loses its anti-cancer effect.

In addition, there may be pesticide residues in tea, even organic tea, also contains a lot of tannic acid, which hinders the absorption of iron in the blood, leading to anemia.

The study also found that drinking too hot tea all the time increases the risk of esophageal cancer. Drinking green tea can reduce women's risk of developing esophageal cancer by about 60%. At the same time, although coffee is not as healthy as tea in people's impression, it also has many benefits. It can also reduce the risk of diabetes, help middle-aged men prevent gout, and reduce the risk of Alzheimer's disease and liver cirrhosis and liver cancer in men.

Scientists believe that the chemicals contained in coffee can be refined into pharmaceuticals to treat heart disease and insomnia. But one study shows that coffee can reduce blood flow to the heart and discolor teeth.

Drinking eight or more cups of coffee a day increases a woman's risk of stillbirth, a Danish study found.

Most of the above studies used black coffee with a small amount of fresh milk and sugar, rather than high-calorie coffee drinks sold in coffee shops.

Duane Mellor, an assistant professor of nutrition at the University of Nottingham in the UK, says coffee and tea are actually better choices than sugary drinks. But he added that some drinks that are high in sugar cannot be called qualified coffee at all. Like a latte with syrup, there is too much sugar, energy and fat.
