People often say, "A simple diet leads to a long life," so what exactly is a simple diet?
"Coarse tea" refers to the more mature and older tea leaves, in contrast to new tea. Although "coarse tea" is bitter and astringent, it contains substances like tea polyphenols, tannins, and tea polysaccharides that are very beneficial to the body. Tea polyphenols are natural antioxidants that can inhibit the damage to the human body caused by carcinogens such as free radicals and nitrosamines. Tannins can lower blood lipids and prevent arteriosclerosis. Tea polysaccharides can alleviate and reduce the symptoms of diabetes, and have effects such as lowering blood lipids and blood pressure.
"Light meals" refer to a light diet. For example, consuming more foods rich in plant fiber in your diet can prevent and treat constipation and digestive diseases, help the body expel excess cholesterol, and protect the normal function of the cardiovascular system.
Plant fiber is a substance that cannot be digested and absorbed by the gastrointestinal tract, including cellulose, hemicellulose, lignin, pectin, gum, and some non-cellulose sugars. Although plant fiber cannot be absorbed by the human body, it has a special function in the body and is very beneficial to human health. It is widely found in coarse grains such as brown rice, naked oats, oats, corn, sorghum, and sweet potatoes; fresh vegetables such as celery, rape, tomatoes, cabbage, cucumbers, Chinese cabbage, pickled mustard greens, kale, radishes, and beans; and fruits such as bananas, apples, oranges, and grapes.
The folk saying, "A simple diet leads to a long life," which means "a diet of coarse grains is beneficial to health," has a certain scientific basis. To maintain good health, the correct dietary method is: to have a diet primarily based on plant-based foods, pay attention to mixing grains and beans, and mixing rice and flour, and to appropriately supplement with various animal-based foods, including meat.
