First, eat less fatty food Less food is not the same as not eating. It is generally recommended that the proportion of fat in energy does not exceed 30%. Studies have shown that reducing fat intake can reduce the chances of tumors and atherosclerosis. However, among the fatty foods, polyunsaturated fatty acids are beneficial to health by. In particular, fish fat rich in DHA can effectively reduce the occurrence of atherosclerosis, so it is recommended to eat at least one fish per week to replenish sufficient DHA. Second, eat more mixed food Refined food in the processing process can easily lead to a variety of micronutrients in addition to carbohydrates and proteins, especially fiber and multivitamins. Studies have found that the consumption of refined food is likely to induce diabetes, and more coarse grains can slow down the development of diabetes. Choose healthy protein foods Use beans, fish and poultry instead of red meat animal protein foods, using protein instead of carbohydrates as a source of energy can effectively alleviate the development of diabetes, but more animal protein can easily lead to fat metabolism disorders, so you should choose relatively healthy protein sources. Fourth, eat more fruits and vegetables Fruits and vegetables are an ideal source of natural vitamins, fiber and many minerals. Although many people believe that eating more fruits and vegetables is beneficial to health, most do not have conclusive evidence. For example, the relationship between fruits and vegetables and tumor incidence is not clear, but fruits and vegetables are more desirable as a source of vitamins than vitamin supplements, and plant fiber is also beneficial to the health of the intestinal flora. Five, how to replenish minerals Some people think that drinking pure water can easily lead to mineral loss and only natural mineral water is good for health, in fact, there is no objective basis for this. Among the various nutrients, minerals are a class of substances that can not be regenerated, must rely on the environment to supplement, humans generally rely on two ways to obtain minerals, one is through diet, the use of animal and plant foods to indirectly absorb minerals from the soil, the other method is to directly supplement minerals, such as our most commonly used salt is a way to supplement minerals. With the development of industrialization and urbanization, agricultural production cannot form a mineral cycle, especially the minerals in human excreta cannot be recycled back to the earth, resulting in the gradual depletion of minerals in the land, leading to a gradual decrease in the level of minerals in food, which on the one hand affects agricultural production and on the other hand may bring about a high incidence of chronic diseases related to mineral deficiency. To solve this problem, the current situation of mineral deficiency in soil and food, as well as the trend of mineral changes in normal recipes, should be fully studied to find the pattern of mineral deficiency, and to use natural mineral reservoirs such as seawater as an important means of replenishing minerals in the human body. How to eat to be healthy is a very important issue, and research in this area is now more in-depth. In fact, there is no absolutely healthy diet, especially since there are individual differences, and food that is healthy for one person may be unhealthy for another. Research on individualized nutritional needs has nutrigenetics, or in the future can give us more reasonable advice. However, the general principles mentioned above are worthy of serious consideration, and it is everyone’s responsibility to promote a healthy lifestyle for the health of themselves and the community.
