Excessive consumption of coarse grains reduces human immunity
Eating coarse grains has become a fashion of carbonization.
Many people like to eat coarse grains because they think it is nutritious, tastes good, and is good for teeth and facial muscles.
However, although coarse grains are good, they should not be eaten too much.
Because it contains too much dietary fiber, it will hinder the body’s absorption of other nutrients, which will reduce the body’s immunity.
Coarse grains are relative to the fine grains such as polished rice, white noodles, etc., which mainly include corn, millet, purple rice, sorghum, oats, buckwheat, wheat bran, and various dried beans such as soybeans, green beans, and red beansMung beans and so on.
Due to the simplicity of processing, coarse grains retain many nutrients not found in fine grains.
For example, it contains less carbohydrates than fine grains, contains additive fiber length, and incorporates B vitamins.
At the same time, many coarse grains also have medicinal value: buckwheat contains other grains without its chlorophyll and rutin, which can treat hypertension; corn can accelerate intestinal peristalsis, avoid colon cancer, and can effectively treat hyperlipidemia,Arteriosclerosis, gallstones, etc.
Therefore, people with hypertension, hyperlipidemia, diabetes, and constipation should eat coarse grains.
Due to the cellulose and phytic acid contained in coarse grains, more than 50 grams of cellulose are added every day, and long-term consumption will cause human protein supplementation to be blocked, a small amount of metabolism will be reduced, causing damage to bones, heart, blood and other organ functions, reducingThe human immune system even affects fertility.
In addition, buckwheat, oats, and corn have a high content of phytic acid. Phytic acid can hinder the absorption of calcium, iron, zinc, and phosphorus, and affect the internal metabolic balance of minerals.
Therefore, the replacement of these minerals should be increased when eating coarse grains.
Too much fiber is harmful to adolescent girls.
Because, hypertension in food will be transformed into fiber replacement initialization in coarse grains.
Decreased absorption of plasma will lead to reduced female hormone synthesis and affect the development of reproductive organs such as the uterus.
Therefore, the fiber absorption of adolescent girls can exceed 20 grams per day.
Due to the weakened function of hypertension in the elderly, eating more coarse grains will cause abdominal distension, digestion and absorption are weakened, and over time, it will lead to malnutrition.
In addition, iron and zinc deficiency will cause anemia and premature brain failure in the elderly.
The best daily cellulose adsorption of the elderly is not more than 25?
In addition, “eating coarse and eating miscellaneous” depends on different groups of people.
As an example, a 35-year-old person, excessive consumption of coarse grains will affect the absorption of proteins, inorganic salts and certain trace elements by the body’s functions, and even affect the human reproductive ability.
Especially for men of this age, the diet should be rich in zinc, selenium, vitamin B and C, and long-term consumption of excessive high-fiber foods, the body’s protein supplementation is blocked, a small amount of intake is greatly reduced, and trace amountsThe lack of elements has led to the slow development of heart, bone and other organ functions and hematopoietic functions, reducing the body’s immune capacity.
At the age of 45, the metabolism rate of the body begins to slow, so you should eat less sweet, less nutritious food, and you should eat all kinds of coarse, miscellaneous grains, soybeans, dried fruits and fresh fruits.
At present, the United Nations has formulated the highest guidelines for fiber foods. It has established that healthy people should include 30?
Recommended standard for 50 grams of fiber.
Studies have found that 6 points of coarse grains and 4 points of fine grains are the most suitable for daily diet.
Therefore, coarse and fine grains are most reasonable to eat.
Eating coarse grains should also pay attention to methods.
From the nutritional point of view, it is better to eat corn, millet, and soybean separately if they are mixed in a ratio of 11: 1: 2, and the nutritional value is higher, because this can make proteins play complementary roles.
The Laba porridge, Babao porridge, and assorted vegetables that we often eat in our daily lives are good coarse grain mixed food.
