It is often said that "a simple diet promotes longevity," but what exactly is a "simple diet"? Nutritionists have found that it is not what most people refer to as various coarse grains and vegetarian dishes. The correct understanding should be a diet that is primarily plant-based, paying attention to mixing grains and beans, and mixing rice and flour, supplemented by various animal foods, and often drinking coarse tea.
"Coarse tea" refers to the coarser, older tea leaves, in contrast to new tea. Although coarse tea is bitter and astringent, the substances it contains, such as tea polyphenols and tannins, are very beneficial to the body. This is because tea polyphenols are natural antioxidants that can inhibit the damage caused by free radicals in the human body and have anti-aging effects. They can also block the damage of carcinogens such as nitrosamines to the body. Tannins, on the other hand, can lower blood lipids, prevent vascular hardening, keep blood vessels unobstructed, and maintain the normal function of the cardiovascular and cerebrovascular systems. In addition, tea polyphenols can alleviate and alleviate the symptoms of diabetes, and have effects such as lowering blood lipids and blood pressure. Therefore, from a health perspective, coarse tea is more suitable for the elderly to drink.
Many people equate "light meals" with coarse grains and vegetarian food. In fact, "light meals" refer to natural foods rich in protein, which include not only a variety of grains and vegetables, but also low-fat chicken, duck, fish, beef, etc.
"Light meals" also has another layer of meaning, which is that the diet should not be too salty. Medical research has shown that a diet that is too salty can easily lead to osteoporosis and high blood pressure, and a long-term diet that is too salty can also lead to stroke and heart disease.
