Dongzhi diet health

1, increase the intake of warm food.

In the cold winter, people often feel uncomfortable because of the cold, and some people are particularly afraid of the cold because of the weak yang in their bodies. Therefore, in winter, it is necessary to use cold-proof food to keep warm and recuperate, so as to warm and nourish the whole body tissues, enhance physical fitness, promote metabolism, improve cold-proof ability, maintain the functional activities of body tissues, resist exogenous pathogens and reduce the occurrence of diseases.

Chinese medicine believes that warm foods should be eaten in winter, such as mutton, dog meat, turtle, sparrow, shrimp, pigeon, quail, sea cucumber, medlar, leek, walnut and glutinous rice.

2. Increase the intake of dietary fiber.

For example: red dates and walnuts.

Walnut contains 40% to 50% fat, most of which are unsaturated fatty acids, which has the functions of lowering cholesterol and preventing arteriosclerosis and hypertension. Walnut is also rich in phospholipids and vitamin E, which can enhance cell activity, promote hematopoietic function and stimulate appetite. All these are of great benefit to enhance the body's immunity and resist the cold.

Jujube is sweet and warm, and enters the spleen and stomach. It is recorded in the ancient book "Pearl Capsule" that jujube can "warm the stomach", contain high calories and rich dietary fiber, and have a strong effect of invigorating qi to protect the human body from cold and winter.

3. Increase the intake of amino acids.

The cold climate increases the excretion of creatine in human urine and accelerates the metabolism of fat, while methyl is needed for the synthesis of creatine and fatty acids and the heat released by oxidation in human body.

So eat more food containing methionine in winter.

4. Increase the intake of vitamins

The cold climate has strengthened the oxidation and heat production of human body, and the vitamin metabolism of human body has also changed obviously. Increase vitamin A, and enhance the cold tolerance of human body. Increasing the intake of vitamin C can improve the adaptability of human body to severe cold, which has a good protective effect on blood vessels.

Vitamin A mainly comes from animal liver, carrots, dark green vegetables and other foods, and vitamin C mainly comes from fresh fruits and vegetables and other foods.
