Seniors are often interested in information about longevity. The length of one's life is closely related to a healthy physical state, and some small aspects of our daily lives have a subtle influence on our health. Few people would think that the several "unpalatable" foods mentioned below are actually superstars for extending life.
Coarse-textured foods
Most people prefer refined rice and processed flour, while disliking foods like brown rice and millet. Some seniors, in particular, have a deep impression of the "scratchy" feeling these foods gave them in their youth. In reality, what scratched the throat was precious dietary fiber. It stimulates intestinal peristalsis, aids bowel movements, and alters the types and quantities of intestinal microbes, reducing the formation of carcinogens. Dietary fiber is widely found in foods with a coarse texture, including whole grains like rice, wheat, and miscellaneous beans, such as brown rice, oats, and red beans. To prevent constipation and colon cancer, one should ensure an intake of 20-30 grams of dietary fiber daily. It is recommended to replace traditional congee with mixed grain porridge for breakfast, and white rice with whole wheat buns.
Astringent foods
People's tastes vary greatly, but some flavors truly lack supporters. The presence of tannins, phytic acid, and oxalic acid can make food astringent. This is because they combine with salivary proteins in the mouth to form precipitates, causing saliva to lose its lubricating properties and the epithelial tissue of the tongue to contract, producing a puckering sensation. However, these substances are highly antioxidant and beneficial for preventing diabetes and hyperlipidemia. For example, the skins of olives, purple grapes, and apples, as well as the skins of walnut kernels, have stronger antioxidant effects than their flesh. It is recommended to eat apples and grapes with their skins on, and when eating walnuts, do not remove the brown skin.
Sour foods
Perhaps only the saying "a sour pregnancy means a boy, a spicy one means a girl" can make people interested in sour things, as their taste is still somewhat different from fruits like watermelon and grapes. In fact, the sour taste of these fruits mainly comes from natural organic acids like citric acid and malic acid, which can promote the absorption of minerals such as iron. If you find sour foods unpalatable, you can make them into fruit jelly, add a small amount rock sugar, and freeze them in the refrigerator; the texture will be greatly improved.
Bitter foods
Natural bitter substances in food also have certain health benefits. For example, naringin in grapefruit and pomelo, polyphenols in tea, polyphenols in red wine, and polyphenols in chocolate are all components that help prevent cancer and heart disease. Quinine in bitter gourd can also enhance the human immune system and help control blood sugar. Therefore, when eating fruits, you must eat a variety of them; don't just eat sweet ones, but also include some bitter and sour ones. Don't throw away the pomelo peels you've eaten; you can cut them into strips and make honey pomelo tea. As for bitter gourd, blanch it in hot water, then chill it and eat it with honey.
Pungent foods
Many office workers avoid strongly flavored foods because, while things like onions and garlic may not feel harsh going down, they leave an unpleasant odor in the mouth afterward. In fact, this pungent flavor comes from substances like glucosinolates and allyl disulfides, which can effectively prevent cancer and are widely found in foods like radishes, garlic, and onions. Therefore, do not neglect them in your daily diet. Radishes can be made into pickles or stewed with pork ribs, onions can be used in cold salads, and the ideal way to eat garlic is raw. If you find your breath unpleasant after eating foods like garlic and onions, you can chew a small amount of tea leaves.
Seniors should take responsibility for their own health at home and eat more of the foods introduced above. However, each food has its own appropriate precautions, so it is best to learn more about them in daily life. A long and healthy life cannot remain just a topic of conversation; only real action can lead you to a happy and fulfilling later years.
