Why do young people’s brains show symptoms of premature aging early? Doctors have even encountered 20-year-olds in outpatient clinics who have shrunken brains as if they were 80 years old. In imaging examinations, premature aging brains look shrunken, with shallow grooves and wide gaps, like shriveled walnut kernels. Patients often suffer from memory loss and lethargy. If not intervened, various diseases such as dementia and neurological abnormalities will occur. The reason for this situation is closely related to a dietary shortcoming, that is to say-eating!
In recent years, we have some misunderstandings about fats and oils. There are two prominent phenomena:
1. We are afraid of fats and dare not eat them, which leads to insufficient intake of fats, that is, not enough food. It lays hidden dangers for brain atrophy. Director Xia said that in fact, the fastest period of human development was between 20,000 and 10,000 years ago, because the proportion of fat in the diet during that period reached 40%! So the human brain has advanced by leaps and bounds.
2. The types and proportions are out of balance, which means eating the wrong food. The fatty acids in oils and fats are essential nutrients for the human body. Only by eating the right proportion and type of fatty acids can the brain appear young. Otherwise, it may age prematurely and even cause a series of health risks in the long run.
So how to correct the "not enough" and "not eating right" in the diet?
As a neurosurgery expert and nutrition expert, Director Xia Meng also has her own daily tips for eating fat, which she will share with you today:
First, fatty foods eaten every day account for 30% of the total energy of the day. If you exercise a lot, the amount of oil you eat must increase.
Second, animal fat can also be consumed in moderation. There are two sources of vegetable fat, one is various vegetable oils for cooking, and the other is nuts that many people ignore.
Third, 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 workers.
Fourth, monounsaturated fatty acids, which are high-oleic acid types, are added to vegetable oils.
