Many people think that polished rice and white flour are the standard of exquisite life, but the life of eating only flour and not coarse grains every day is capitalized as "rough" Knock on the blackboard and draw the key points. What are the disadvantages of eating flour and rice instead of coarse grains for a long time?

First, the nutritional value is low; Easy to cause disease

I wonder if you have noticed that northerners who eat more coarse grains are generally stronger and taller than southerners who like polished rice and white flour for a long time. Why? This has a lot to do with the long-term staple food of polished rice and white flour. Many parents and children think that white rice and white flour are delicious and refreshing, and have high nutritional value. This is a misunderstanding. Nutritionists have done research, and the nutrients such as vitamins, minerals and protein in polished rice and white flour are far lower than those in whole grains such as brown rice and wheat grains.

Aleurone layer is removed from polished white rice and refined flour during processing, while aleurone layer is rich in B vitamins, minerals and protein. The more precise the processing of rice and flour, the lower the aleurone layer content and the less the nutritional components, that is, the lower the nutritional value. Therefore, the petite in your eyes is probably malnutrition.

In addition, the biggest defect of polished rice and polished surface is that most vitamin B 1 is removed during processing. Long-term consumption of polished rice and white flour is prone to vitamin B 1 deficiency, beriberi, symmetrical peripheral neuritis and other symptoms, such as fatigue, palpitation, fullness, constipation, and even stomach edema. What? ! The human body will also be affected by the lack of minerals magnesium and zinc, which will make the muscle layer soft. The low content of magnesium in human body may also lead to premature heart beats and high blood pressure.

Second, the lack of cellulose; Easily lead to obesity.

Some people do not eat brown rice and coarse grains, but only polished rice and white flour. As we all know, the bran of rice and wheat contains a variety of trace elements and plant cellulose needed by human body, such as chromium and manganese, which are the highest in whole grains, beans and nuts. If refined through processing, these two elements will be greatly reduced. Plant cellulose can increase cholesterol excretion and reduce blood cholesterol content. Food is too fine and cellulose is too little, so it is not easy to feel full, which often constitutes overeating and obesity! ! !

Third, it causes acidic constitution; Lead to sub-health

The natural environment pays attention to balance, and the "internal environment" of the human body also needs balance, one of which is "acid-base balance", because all metabolic reactions of the human body must be completed at a suitable pH value. After living a well-off life, there are more and more acidic foods in people's diet, such as meat, poultry, eggs, fish and refined rice noodles. However, alkaline foods that can help regulate the internal environment, such as vegetables, fruits, beans, potatoes, bacteria, algae, etc., are not eaten enough to balance the acidic substances brought by excessive animal foods. In this case, the pH value of staple food is particularly important. Because the staple food is the most eaten in a day, if it is less acidic, it can greatly reduce the burden of acid-base balance of the body. To do this, we should eat more coarse grains or choose whole wheat and brown rice.

Love tips:

People who are used to fine diet should adjust their diet structure in time to help their bodies get more fiber and protein. It has long been suggested abroad that the diet should "return to nature", eat less processed food and eat more natural and unprocessed food. However, it is almost impossible to eat coarse grains or fast food or processed food in restaurants at present. In the case that refined rice flour cannot be avoided for three meals a day, it is best to leave some wheat grains at home.

Among coarse grains, wheat grains are whole wheat grains, which contain all the nutrients of wheat grains. In other words, the wheat grain is the state before the wheat is shelled and ground into flour. Wheat grains are divided into soft and hard, but these two names do not represent their hardness. The difference between them lies in its gluten content. Soft wheat grains have low gluten content and are ground into flour with skin. Hard wheat kernels have high gluten content and are ground into ordinary nutritious flour.

Then the problem is coming. There are many kinds of wheat in the market. How should friends choose?

First look at the face value, oh no, look at the color. Nutritionists choose black wheat because the protein of black wheat is higher than that of ordinary wheat, and it contains iodine, and rye kernels are derived from black wheat. According to experts' evaluation, rye kernel is an ideal nutritional health food, which is suitable for patients with protein deficiency and weak constitution caused by various reasons.

Second, look at the place of origin. It is suggested that friends choose rye kernels in Tekes County, Yili, Xinjiang. In general, Tex is located in the controlled area of inversion layer, which is a typical continental climate in the north temperate zone. There are abundant sunshine resources, and the temperature difference between morning and evening is about 10 degrees Celsius. Black wheat can retain nutrients to the maximum extent during its growth. The natural environment enables rye to grow in excellent air and water quality.

Third, look at the nutritional value. Rye kernel contains a large number of amino acids that cannot be synthesized by human body, in which the content of lysine is 1.5 times that of wheat, and the content of histidine, which is indispensable for children's growth and development, is 1.79 times that of wheat. Eating more rye kernel and its products can promote the healthy development of children. The trace element fluorine contained in rye kernel is an important component of bones and teeth. Regular consumption of rye kernel and its products can prevent dental caries and osteoporosis in the elderly.

Finally, it depends on efficacy and function. Studies have shown that rye kernel has the functions of preventing cancer, delaying aging, lowering blood pressure, reducing blood lipid and preventing diabetes.

In a word, you can't live a healthy life without whole grains. Let's make a healthy family together. Starting today, we should pay attention to whole grains, care for health, balance nutrition and enjoy the nourishment from whole grains. Let's live with Mairen.
