Whey protein and health
The three most important basic substances of the human body are: vitamins, proteins, and phospholipids
The human body is composed of cells, which are composed of: nucleus, cytoplasm and cell membrane. Only healthy cells have a healthy body. The life span of a cell is generally 120--160 days. Old cells are constantly undergoing apoptosis and are replaced by new cells, which continue again and again, allowing life to continue. The life activities of cells (material metabolism, information transmission) are carried out through the cell membrane, and the basic materials that make up the cell membrane are protein and lecithin. The ratio is: 70% is phospholipids and 30% is protein; during cell regeneration, if there is a lack of high-quality protein, it will cause congenital defects in the cells. In addition, whey protein increases intracellular glutathione levels, thereby stabilizing cells and the internal environment, and achieving the purpose of enhancing cell vitality and defense functions.
Protein plays a very important role in cell movement. It participates in the transportation of oxygen, information transmission, and material metabolism. Therefore, protein is the material basis of life, an important component of all cell and tissue structures, and a life process. The substance that plays a decisive role in it.
Human protein is composed of more than 20 α-amino acids in different combinations, of which 8 are determined for adults and 9 for infants and young children, which cannot be synthesized by the human body and require external supplementation.
1. The role of protein in the human body:
Directly synthesize new tissue, promote growth and development, and promote wound repair;
Catalyst of life activities—synthesis of enzymes;
Synthesis of hemoglobin, which transports oxygen and carbon dioxide;
Constitute antibodies (immunoglobulin) and various hormones (such as insulin) that protect the body against infectious diseases;
Maintain the acid-base balance in the body;
Ensure the normal distribution of water in the body;
genetic informationtransfer;
Transport of various nutrients;
2. Which groups of people need to consume more high-quality protein
People who are losing weight pay great attention to reducing the intake of energy in their meals. If there is insufficient heat energy in the meal, most of the protein in the meal will be converted into glucose to supply heat energy, thus causing a lack of protein in the human body.
People with poor digestion and absorption of the body, such as esophageal cancer, gastric cancer, etc., can cause difficulty in eating. Lack of gastric juice or pancreatic juice can cause protein indigestion and reduced absorption. Other chronic diseases such as: intestinal tuberculosis, ulcerative colitis, etc.
People with synthesis disorders in the body:
The liver plays a primary role in protein synthesis. If you suffer from liver diseases such as cirrhosis, liver cancer, hepatitis, and fatty liver, the liver's ability to synthesize protein will be reduced and hypoproteinemia will easily occur.
Those who decompose too much and suffer too much loss:
Suffering from various infectious diseases, trauma or surgery, hyperthyroidism, etc. can accelerate the decomposition and destruction of tissue proteins.
Pregnant women, wet nurses and convalescent patients;
Office white-collar workers with high mental stress
Sub-healthy, weak and convalescent people, vegetarians
For middle-aged and elderly people, due to the decline in digestive, absorptive and synthetic functions, they cannot meet the needs of the body.
3. Several important benefits of taking whey protein
Whey protein can provide glutathione precursors, thereby improving the antioxidant function of cells throughout the body, allowing the human body to obtain the following benefits:
Enhance immune function
The human immune system is the most complex and miraculous system designed by nature. To maintain the normal function of the immune system, immune cells must have sufficient activation properties, the ability to reproduce and differentiate, and must have the killer weapon to eliminate invaders. Glutathione plays this role. During the immune response process, glutathione ensures the activation of immune cells, their continuous proliferation, differentiation into various combat units, and equipped with anti-virus weapons to eliminate viruses, bacteria, and tumor cells. Whey protein powder provides rich glutathione precursors, so it can quickly enhance the body's immune function.
Regulate blood lipids and benefit the health of the cardiovascular and cerebrovascular systems
50% of the composition of HDL is protein, more than 30% is lecithin, and the rest is cholesterol and triglycerides. It can be seen that the formation of high-density lipoprotein requires not only sufficient lecithin in the blood, but also abundant high-density lipoproteins.Protein also plays a vital role. Due to the excellent bioavailability of whey protein powder, it is easily digested and absorbed by the human body after consumption, providing the body with the raw materials for synthesizing high-density lipoprotein in a timely manner to achieve the purpose of regulating blood lipids and protecting cardiovascular and cerebrovascular systems.
Can remove free radicals from the body
Modern medicine believes that free radicals are the source of all diseases. Human cells rely on the antioxidant network established in the body to resist free radical attacks. One of the most important antioxidants in this system is glutathione. Glutathione is the main force in scavenging free radicals and is praised by scientists as the "master antioxidant." Glutathione is not only directly involved in scavenging free radicals, but also plays a regulatory role in other antioxidants such as vitamins E and C. Maintain (restore) their active state. However, glutathione cannot be supplemented from outside the body and can only be synthesized by cells in the body, and whey protein can provide the raw materials (precursors) for cells to synthesize glutathione. Sufficient glutathione. Therefore, taking whey protein can increase cellular glutathione levels and enhance the capacity of cellular antioxidant systems.
IV. What is whey protein
Whey protein is a complex protein extracted from fresh milk. It contains essential amino acids and many nutrients. It is mainly composed of β-lactalbumin, immunoglobulin, lactoperoxidase, lysosomes, lactoferrin, etc. , each component has a unique biological effect. Easily digestible and lactose-free.
5. How much whey protein does milk contain?
The composition of milk is 87% water and 13% milk solids, of which 37% lactose, 30% fat, 27% milk protein, and 6% ash (minerals). Only 20% of milk protein is whey protein and 80% is casein. That means: Whey protein is only 0.7% present in milk.
6. What is the biological value (BV) of protein?
The biological value of protein is referred to as biological value, which represents the extent to which food protein is retained by the body after absorption. The greater the biological value, the higher the bioavailability of the food protein.
7. What is protein digestibility
Protein digestibility reflects the degree to which protein is broken down by the action of digestive enzymes in the body. The higher the digestibility, the easier it is for the food protein to be digested and absorbed.
8. What is net protein utilization
Net protein utilization (NPU)) is a method that combines protein biological value with digestibility to evaluate protein quality. The higher the net utilization value, the better the quality of the protein. This method can more comprehensively reflect the quality of protein.
9. Why is whey protein the king of protein?
Important indicators for evaluating protein quality are the biological value of protein and net protein utilization. The higher these two indicators, the better the protein quality.
Nutritional value of major proteins
It can be seen from this that the biological value of whey protein is as high as 104, so in the nutritional world, it is called the king of protein.
10. How much protein should be consumed every day
Chinese nutritionWould recommend:
Teenagers during the growth and development period should consume: 80-90 grams of protein and 25-30 grams of fat
Adults should consume: 65-80 grams of protein and 20 grams of fat
Intake of pregnant women and nursing mothers: 90-110 grams of protein, 20 grams of fat
11. If you eat meat and eggs every day, do you need to supplement with whey protein powder?
The human body is constantly consuming protein every day. People can also absorb protein from their diet, especially high-protein foods, but these high-protein foods also bring many disadvantages. From a nutritional point of view, animal proteins such as meat, poultry, fish, and seafood are high-protein foods, but their essential amino acid composition ratio is different from the ratio required by the human body, and cannot be well utilized by the human body, and among them Containing excessive saturated fat, cholesterol, concentrated hormones, antibiotics and other harmful substances that are harmful to the human body can easily cause fat accumulation and increase cholesterol in the human body, leading to the occurrence of cardiovascular diseases. Studies have shown that for every 10 grams of protein consumed, the amounts of various foods required and the amount of fat consumed are as follows:
Food name Dosage (grams) Amount of fat consumed at the same time (grams) Whey protein powder 12.5 0.93 Eggs 70 8.83 Milk 333 10.66 Lean Pork 50 3.1 Lean beef 49.5 1.14 Soybeans 28.5 4.56 Plain tofu 123.5 4.57
It can be seen from this that when we consume a certain amount of protein, taking whey protein powder consumes less total intake than other foods, and at the same time, the fat content is also the least. In this case, supplementing with high-quality protein powder through scientific means is your best choice.
