Another advantage of drinking green tea and black tea every day is that it can reduce the chance of heart disease. Antioxidants contained in green tea, black tea and oolong tea can prevent the oxidation of low-density lipoprotein (bad) cholesterol, increase high-density lipoprotein (good) cholesterol and improve vascular function.

Here are some tips for drinking tea:
Drink tea several times a day to absorb antioxidants and other beneficial plant elements. It is best to drink three cups of green tea every day.
-Soak the tea leaves for three to five minutes before drinking, and let the tea leaves precipitate catechins.
The most effective way to absorb catechins and flavonoids is to drink freshly brewed tea, decaffeinated, bottled and instant tea (that is, instant three-in-one black tea and the like), which all contain less beneficial substances.
Tea will hinder the absorption of iron in fruits and vegetables, so adding lemon, milk or avoiding drinking tea during meals (only between meals) can offset this problem.
Supplementary explanation:
Studies also show that drinking green tea is more beneficial than oolong tea and black tea. Because black tea is fermented and dried, the bioactive substance-tea polyphenols in fresh tea is oxidized, which makes black tea lose most of the beneficial tea polyphenols and greatly reduces its nutritional value. However, the method of making green tea is to steam the tea leaves a little and then dry them. The steaming process can prevent the oxidation of tea polyphenols and make the chemical composition of the finished product very similar to that of new tea.
