Experts pointed out that green tea is the richest in antioxidants because it doesn't undergo fermentation. Instead, its leaves are briefly heated, then rolled and dried, which preserves the catechins and flavonoids that fight free radicals, promote healthy blood vessels, and improve blood lipid levels. However, these compounds can increase stomach acidity, so it's advisable not to drink it on an empty stomach and to limit consumption to a maximum of four cups per day to avoid straining the liver and kidneys.
White tea , on the other hand , is described by experts as "the gentlest and most beneficial," as it is prepared from young buds and leaves with minimal heat treatment. It contains less caffeine and more antioxidants, making it a suitable choice for pregnant women. However, it may slightly lower blood pressure, so it is not recommended for those with low blood pressure, and it should not be given to children under six years old due to its high concentration of active plant compounds.
Black tea is a potent stimulant thanks to its deep fermentation process, which produces theaflavins and thearubigins, compounds that support blood vessel walls and lipid metabolism. However, it is rich in tannins, which can cause heartburn and hinder iron absorption, so it is best consumed after meals. Those with anemia, anxiety, or insomnia should limit their consumption. Adding milk can mitigate its negative effects, although this partially reduces its antioxidant benefits.
Regarding Pu-er tea (of the "Shu" and "Shin" varieties), experts confirmed that it is the most beneficial for the digestive system and gives a deep feeling of warmth. However, its high caffeine and purine content makes it unsuitable for pregnant women, gout patients, kidney stones, high blood pressure, and stomach disorders. It is also strictly prohibited for children under the age of ten.
The experts concluded their recommendations by emphasizing that the choice of tea should take into account individual health characteristics. When chosen correctly, tea can gently and effectively support heart health, immunity, and the digestive system, but it can pose a risk to those with certain health conditions such as high blood pressure, gastritis, or during pregnancy.
