So, what exactly causes premature brain aging?
Have you been tricked by these fat-eating misunderstandings?
Eat not enough Fear of fat and dare not eat
Have you ever been wary of "high-fat food", if you think that eating only "low-fat" and "non-fried" foods for a long time is a healthy eating Xi, in fact, you have fallen into the misunderstanding of "afraid of eating oil". In fact, it is the excessive intake of starch that really causes fat accumulation on the stomach, and it is insulin rather than high-fat foods that allow fat to accumulate on the stomach. Xia Meng, chief physician of the Department of Neuronutrition of Sanbo Brain Hospital of Capital Medical University, introduced that among the Alzheimer's disease patients who are treated, many patients like to eat fine rice noodles, and excessive intake of starch will lead to blood sugar instability, which is closely related to Alzheimer's, in addition, too little fat intake can also cause glossopharyngeal neuralgia or herpes zoster and other neuralgia diseases.
Eating the wrong amount of fatty acids is out of balance
Fatty acids in oils and fats are essential nutrients for the human body, and can be divided into monounsaturated fatty acids, saturated fatty acids and polyunsaturated fatty acids according to the saturation of fatty acids. Director Xia pointed out that the daily diet needs to increase the proportion of monounsaturated fatty acids, and at the same time ensure the appropriate intake of saturated fatty acids and polyunsaturated fatty acids.
The meat we usually eat mainly contains saturated fatty acids, fish, nuts, and vegetable oils contain more polyunsaturated fatty acids, because polyunsaturated fatty acids are easy to oxidize, although moderate intake is beneficial to the body, but if we consume too much, it will produce inflammatory factors due to oxidation, causing damage to our blood vessels.
Monounsaturated fatty acids can be good antioxidants, which is also of great help in maintaining our blood lipid health and reducing the risk of cardiovascular and cerebrovascular diseases. Therefore, the daily diet can increase the proportion of polyunsaturated acids, Director Xia introduced that in addition to the olive oil we are familiar with, high oleic peanut oil and tea seed oil on the market can supplement the monounsaturated fatty acids required by the human body. If you can replace some carbohydrates with some fats, especially monounsaturated fatty acids, it is helpful for sugar control, fat control and physical health.

So how to correct this "not eating enough" and "eating wrong" in the diet?
1. The fatty foods eaten every day account for 30% of the total energy of the day. If you exercise a lot, you need to increase the amount of oil you eat.
2. Animal fat can also be eaten in moderation. There are two sources of vegetable fat, one is a variety of vegetable oils for cooking, and the other is nuts that many people will ignore.
3. Animal oil should come from fish, lean meat, eggs, whole milk, and offal as much as possible. Fatty meat is also edible, especially for manual laborers.
4. Vegetable oil can use oil with high oleic acid content.
