Which drink is healthier, tea or coffee?

Some people can't wake up without a cup of coffee in the morning, while others like to start their day with the scent of tea. What are the benefits and risks of tea and coffee, and which is better for health? According to the Daily Mail, a new study shows that tea and coffee have their own advantages in terms of health benefits, but they also have their own risks.

Tea helps prevent type 1 diabetes and reduces the risk of obesity, heart disease and cancer. 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. Drinking green tea can reduce women's risk of developing esophageal cancer by 60%. White tea, made from the buds and leaves of tea trees, contains higher antioxidants that fight aging, inhibit the growth of new fat cells and prevent cancer.

However, there may be pesticide residues in tea, even if it is labeled as organic tea. The tannic acid in tea also hinders the absorption of iron in the blood, which leads to anemia. The study also found that drinking too hot tea increases the risk of esophageal cancer.

At the same time, the study found that although coffee is often considered to be not as healthy as tea, it does have many benefits, such as helping middle-aged men prevent gout, liver damage, liver cancer and delay Alzheimer's disease. Coffee can also increase the efficacy of painkillers, which can improve short-term memory and reaction time in the elderly. Scientists believe that the chemicals in coffee can be used to develop new drugs to treat heart disease and insomnia.

But other studies have shown that coffee reduces blood flow to the heart and discolors teeth. Drinking more than eight cups of coffee a day can significantly increase a woman's risk of stillbirth, a Danish study has found. Whether most of the above studies were based on black coffee with a small amount of sugar and milk, and did not choose the high-calorie coffee sold in coffee shops.

Duane Mellor, an assistant professor of nutrition at the University of Nottingham, opposes drinking coffee disguised as high-sugar drinks. According to a recent online survey, Christmas cups of coffee in most coffee chains contain more sugar than the recommended daily intake. A latte with syrup will have extra sugar, calories and fat and become another drink, says Duane Mellor. The claim that coffee and tea have dehydration effects is also false.

However, Duane Mellor does not advise people to stop drinking coffee or tea because they are a better choice than sugary drinks. "it used to be thought that tea is good for health, but with the discovery of new research, coffee also has many benefits." "it's a tie," Duane Mellor said. "people still choose according to their preferences."
