Professor Liu Zhonghua believes that rice is the staple food for Chinese people. Focusing on food health through rice is a good approach, and research on the health benefits of tea is currently a global hotspot. Based on research findings from various countries, using tea water, especially dark tea water (with Fu Brick Tea being the most typical), to cook rice can prevent at least five diseases:
1. Prevention and Treatment of Cardiovascular Diseases
Tea polyphenols are the main substances in tea, accounting for 70% to 80% of the water-soluble extracts in tea water. Modern science has proven that tea polyphenols can enhance vascular toughness, especially preventing microvascular rupture. Moreover, tea polyphenols lower cholesterol and inhibit atherosclerosis. Middle-aged and elderly people who consistently eat rice cooked with tea water can soften blood vessels, reduce blood lipids, and prevent cardiovascular diseases.
2. Prevention of Stroke
One cause of stroke is the generation of lipid peroxides in the body, which leads to loss of elasticity in blood vessel walls. The tannic acid in tea water can inhibit the formation of lipid peroxides, effectively preventing stroke.
3. Anti-Cancer Effects
Tea polyphenols can block the synthesis of nitrosamines in the human body. Amines and nitrites are widely present in food and can easily form carcinogenic nitrosamines at 37 degrees Celsius and under appropriate acidity. Therefore, tea water can prevent the formation of nitrosamines, thereby helping to prevent tumors.
4. Prevention and Treatment of Digestive Tract Diseases
Currently, many scientists are studying the components and health benefits of the "golden flower" in Fu Brick Tea. Experts agree that the "golden flower fungus" in Fu Brick Tea contains microorganisms that provide special protection and regulation for the gastrointestinal tract. Imports of Fu Brick Tea to Japan and South Korea have doubled in recent years. They believe that Fu Brick Tea is the best auxiliary medicine for all digestive tract diseases and is particularly effective for certain gastrointestinal functional disorders. In Japan, many people use Fu Brick Tea water to cook rice and wash their faces, but they do not want the Chinese to know because they cannot produce Fu Brick Tea themselves.
5. Prevention of Dental Diseases
Tea contains fluoride, an essential substance for tooth dentin. Fluoride enhances tooth toughness and acid resistance, effectively preventing dental caries.

Some experts specifically point out that Fu Brick Tea containing the "golden flower" (scientifically named "Eurotium cristatum") may lead to a significant scientific discovery. Using Fu Brick Tea water to cook rice and consuming it long-term may yield unexpected effects.
