An official survey by the Chinese Nutrition Society found that food fat intake and body fat content are both high, especially among urban populations, so it seems good to live on low-fat foods. However, fat is undoubtedly useful to the body, and a healthy body needs to retain 20-30% of fat, slightly lower for men and higher for women. Lipids in food are the raw material for the synthesis of many physiologically active substances in the body, such as steroid hormones. It’s really hard to imagine not consuming any fat-containing foods at all… skinny bones + dry, rough skin? Do you really want that? What’s annoying is the excessive deposition of fat in the body, which is not only unsightly but also unhealthy. From a health point of view, we can’t allow our body fat content to exceed 25% (men) to 30% (women) of our body weight. There are specialized body fat measuring devices that can help us get information about our fat content. You can ask for it at a major hospital. The other “20-30%” in relation to fat is the percentage of total food energy it accounts for. A low-fat diet is one in which fat provides no more than 20% of the energy. Such a diet is more suitable for those who suffer from hyperlipidemia, cholecystitis, acute pancreatitis, diarrhea and so on. Even if you are losing weight fat, we advocate a low-calorie balanced diet, not simply low-fat ah. If you want to control your weight and improve your body shape, don’t just go with the fat. You know, sweets, fruits, drinks, coffee mate, ice cream, potato chips create a low-fat, high-carbohydrate diet structure is more problematic. Food fat also has good and bad, can do meat and vegetable mix is good, we really should refuse is high fat, high sugar, high calorie diet structure, not contain fat food ah.
