Cereal Brain, a book written by a neurologist, has a core view that is quite different from our cognition. The food that really harms our health, especially brain health, is not fat, not cholesterol, but grains (gluten, such as flour and bread) and various carbohydrates (such as sugar).

The book puts forward a common disease, gluten allergy, which may lead to various neurodegenerative diseases and other physical problems, such as dementia, ADHD and other neurological disorders. Even without gluten allergy, grains are not human friends.

Although a large number of human chemical reactions and experimental results are quoted in the book, the reason behind it is very simple. The genes and structure of human body have been gradually optimized for tens of thousands of years. In this process, most of the time, the main source of human food is fat and nuts, while carbohydrates have become the staple food of human beings for only a few thousand years. From the physiological structure of the brain, fat and cholesterol are the best friends of the brain, and the real harm is the oxidation reaction and free radicals caused by grains and sugar, which leads to diabetes.

Therefore, the author's suggestion is very simple. The three elements of health include diet, exercise (similarly, human physiological structure is designed for a certain amount of exercise every day) and sleep. On the diet, you need to cut off the following foods:

Gluten-containing cereal bread, all kinds of pasta, cakes, baked goods and cereals.

All kinds of processed carbohydrates, sugar and starch, such as potatoes, sweet potatoes, biscuits, cakes, candy, ice cream, jam, fried food, sugar and honey.

Margarine and soybean oil, corn oil, peanut oil, sunflower oil, wheat germ oil, etc.

Soybean and soybean products.

With such a long list, is life boring from now on? No, there are many delicious foods to eat, including:

Oils and fats: olive oil, coconut oil, butter, nuts and cheese.

Protein: whole eggs, wild fish, shrimp, crabs, and all kinds of meat.

Vegetables: all kinds of green leafy vegetables

Low sugar fruit.

Of course, a moderate amount of rice is acceptable. At the same time, some supplements can also be recommended, including DHA, resveratrol (the so-called red wine is mainly beneficial to health, and the content in red wine is negligible), turmeric, probiotics and vitamin D.
