Low-fat diet is out of date. It does not reduce cardiovascular and cerebrovascular diseases, but increases the risk of diabetes and Alzheimer\’s disease. Is this true?
Fat makes people both love and hate it. Without it in the food, the food will not be fragrant; if it is present, the food will be greasy; without it, the human body will be skinny and weak; if it is present, the body will be fat and will greatly affect the appearance. After seeing this, I think most readers have already figured out: a lack of fat is not enough, and too much fat is not enough.
When looking at the amount of fat in a meal, three conditions must be considered together. One is the total energy provided by the food, the second is the proportion of fat in energy, and the third is whether the source of fat is taken care of. To the balance of meat and vegetable oil. If these three conditions are not taken care of together, simply talking about high-fat diet and low-fat diet will cause certain misunderstandings and even extreme behaviors.
For example, one current weight loss method uses a \”high-fat meal\”. The theory is that if you eat too much starch or sugar, insulin will be quickly stimulated, causing the sugar to turn into fat and be stored in the body. ; If you choose a high-fat meal, you can reduce the amount of sugar converted into fat and accumulated. This theory seems reasonable, but the promotion ignores another key element, which is the combination of energy and food. If energy is not controlled and only \”high fat\” is used, it may have the effect of reducing weight in the short term, but in the long run it will definitely cause further metabolic disorders, hyperlipidemia or hyperglycemia, which is actually not conducive to healthy.
A large number of studies have shown that excessive fat intake can not only induce obesity, but also lead to non-alcoholic fatty liver disease, diabetes, cardiovascular disease, etc. Of course, unless there are special circumstances, there is no special emphasis on low-fat meals.
So there are two keywords that should be considered in the choice of fat. One is \”source\”, such as plant sources (such as grains, soybeans, vegetable oils), animal sources (such as meat, eggs, milk, fish), and the other is \”appropriate amount\”. Therefore, the new dietary guidelines emphasize eating more fruits and vegetables, milk, and soybeans, moderate amounts of fish, poultry, eggs, and lean meat, and less salt and oil. Note that \”less oil\” here refers to not consuming too much cooking oil, so as to ensure a balanced energy supply. Fat sources are diverse, but excessive intake is important.
