Protein's deficiency, also known as hypoproteinemia, is characterized by decreased plasma protein, decreased colloid osmotic pressure and generalized edema.
Protein is one of the two vital substances in human body, and it is also an important substance for regulating human physiological functions, and it is an essential nutrient element for human body. However, under the overwhelming publicity of commercial advertisements, people pay more and more attention to vitamins and minerals. Who knows,
When your body is in the following situations, you are more likely to lack protein!
1. Low immunity
When you find yourself more susceptible to influenza than the people around you, you may know that this is a sign of low immunity, but what you don't know is that the low immunity is probably due to the lack of protein. Antibodies in human body are important substances to resist diseases, and antibodies are protein with some special structures. When people lack protein due to insufficient dietary intake, the body's antibody synthesis is insufficient, and the body's ability to resist diseases will be greatly reduced.
2. Osteoporosis
The human skeleton consists of two parts. One part is an inorganic substance represented by minerals such as calcium and magnesium, which mainly maintains the hardness of the human skeleton. The other part is organic matter represented by collagen, which mainly maintains the toughness of human bones. When the human body lacks protein, the collagen synthesis is insufficient, which may lead to the decrease of bone toughness and brittleness. In addition, because the minerals in the bones need to attach to the structures erected in protein, if there is no protein in the bones, there is nowhere for inorganic salts to attach, which may lead to osteoporosis.
3. "Fat lines" appear on the body
There are collagen and elastin in our skin, which can increase the elasticity of the skin. Without it, our skin will become brittle and will be torn by external force. Many fat people have some "fat lines" on their calves, waist and buttocks. In fact, it is because they have too much subcutaneous fat and stretch their skin, but the skin lacks collagen and elastin, which leads to the inability to recover after stretching and the appearance of "fat lines". The same is true for some women who have "stretch marks" after pregnancy and childbirth.
Easy fatigue
Many people are more prone to fatigue than others, especially when there are many people and the air is not circulating. This may be because these people have low hemoglobin content in their blood. Human hemoglobin is mainly a carrier for delivering oxygen and discharging carbon dioxide to various tissues and organs of the human body. If hemoglobin is lacking, the human body's ability to obtain oxygen will decline, and if the body does not get enough oxygen, it will be prone to fatigue, drowsiness and depression. Because of its special physiological mechanism, women are more likely to lack hemoglobin than men.
5. Intravascular cholesterol deposition
As we all know, if you eat too much cholesterol in your diet, it will lead to the deposition of cholesterol in your blood vessels, which will lead to a series of cardiovascular and cerebrovascular diseases. But in fact, if the human body lacks protein, it will also cause cholesterol to deposit in blood vessels. This is because cholesterol needs a carrier protein to transport in human blood, and only when this carrier protein keeps a normal level can the normal circulation of cholesterol be guaranteed. Without this carrier protein, the running speed of cholesterol in the blood will be greatly slowed down or even stagnated. As a result, cholesterol is deposited on the blood vessel wall, eventually forming a thrombus.
6. Edema
Many patients with malnutrition will have a symptom, that is edema. It stands to reason that malnourished people should be thin, but why do some people get edema? The reason is that protein in blood plays a very important role in maintaining colloid osmotic pressure in human body. If people lack protein, the osmotic pressure will be unbalanced, and a large amount of water will enter the intercellular space, leading to edema. Therefore, when protein's malnutrition occurs in human body, there will be symptoms of edema.
7. Children's rickets
Many parents say that their children often "can't stand straight". At this time, some people will beat and scold easily, and some people will say that this is "innate and cannot be changed." In fact, if your child can't keep an upright posture often, it may be that his muscles lack protein. Protein in human muscles provides strength support for muscles. If it is lacking, there will be muscle weakness, which shows that the child can't stand straight.
8. Diabetes
Some people may say that the cause of diabetes is hyperglycemia, which is only related to sugar. How can it have anything to do with protein? In fact, diabetes is a metabolic syndrome, which is related to many nutrients. Protein is related to many hormones in the human body. If the human body lacks protein, the amount of insulin (a polypeptide hormone) synthesized in the body will decrease. Insulin is the key hormone to control the increase of blood sugar. Therefore, if the human body lacks protein, it may lead to an increased risk of diabetes.
Protein plays an extremely important role in the structure and function of human body, but the lack of protein in human body has many hazards, only eight of which are listed above. The best way to supplement protein is through daily diet, because protein needs to be converted into small amino acids in our digestive system to be used by people, so oral administration is more effective than external use; And the food we eat every day is rich in protein, so as long as we can make a reasonable diet, we don't have to buy expensive protein powder.
How much protein do we need to add every day? For normal healthy people, if you eat a mixed diet (that is, both vegetarian and vegetarian dishes), the daily required protein quality is your weight (kg) multiplied by1.1; If you are a vegetarian, you need to increase it to 1.5 to 2.0; If it is pure meat, or the proportion of meat is large, it will drop to 0.8.
In addition, we should also pay attention to control the intake of fat when supplementing protein, because generally, foods with high protein content have relatively high fat content. Don't eat too much fat to supplement protein, it's not worth the candle.
