Whey protein and lactoferrin seem to have only one word difference, but they are quite different. I will introduce them to you today.
lactoalbumin
Whey protein, known as the king of egg white, is a kind of protein extracted from milk. It has the characteristics of high nutritional value and easy digestion and absorption, and contains a variety of active ingredients. It is recognized as one of the high-quality protein supplements for human body.
Whey protein refers to protein dissolved and dispersed in whey, accounting for about 18% ~ 20% of milk protein, which is divided into two parts: heat stable whey protein and heat unstable whey protein. When the whey solution is boiled for 20min at pH = 4.6 ~ 4.7, a kind of protein precipitated is heat-unstable whey protein, which mainly includes whey protein and lactoglobulin. Protein, which does not precipitate, is a heat stable protein, accounting for about 19% of whey protein.
Whey protein is a high-quality complete protein, which contains 8 essential amino acids needed by human body, and the ratio is reasonable, which is close to the demand ratio of human body. It is an indispensable essence of human growth, development, anti-aging and other life activities.
Whey protein is easily digested and absorbed. The whey protein in breast milk contains 60% and casein contains 40%, so the baby feces in breast milk are soft and few.
Whey protein contains many active ingredients such as-lactoglobulin,-whey protein, immunoglobulin and lactoferrin.
Effect of Whey Protein on Healthy Growth of Infants
1, enhancing immunity
Taking whey protein concentrate can promote humoral immunity and cellular immunity and stimulate human immune system, so whey protein is a very good protein for enhancing immunity.
2, antibacterial, anti-inflammatory, anti-Helicobacter pylori
Whey protein has many functions such as antibacterial, anti-inflammatory and immunomodulation. In recent years, foreign studies have shown that whey protein has anti-Helicobacter pylori activity in vivo, and has curative effect on gastritis, gastric ulcer and cancer caused by Helicobacter pylori.
Step 3 stabilize blood sugar
Whey protein can improve insulin sensitivity and stabilize postprandial blood sugar, and its blood sugar control effect is better than other common protein sources (meat and beans). It was found that taking whey protein before meals can effectively increase insulin secretion and reduce postprandial blood sugar by about 265,438 0%.
Step 4 increase muscle mass
Most foods add too much fat while providing protein. Whey protein can reduce fat on the basis of supplementing high-quality protein. Therefore, it is a very good nutritional supplement for muscle trainers.
Lactoferrin
Lactoferrin is one of the main components of whey protein, accounting for 10%- 15% of the total milk protein. Generally, it only exists in human milk and mammalian milk. It is one of the important members of the non-specific immune system in the mother and the core immune protein. It has antibacterial, antiviral and immunomodulatory functions, and is known as the first line of defense for health, which is extremely important for the nutritional needs and growth and development of newborn babies.
Lactoferrin is an important non-heme iron-binding glycoprotein in milk and a monomer glycoprotein with bactericidal activity in neutrophil granules. Lactoferrin is not only involved in iron transport, but also has powerful biological functions such as broad-spectrum antibacterial, antioxidant, anticancer and immune system regulation, and is considered as a new antibacterial and anticancer drug.
What effect does lactoferrin have on the baby's body?
1. Promoting the iron absorption of lactoferrin can improve the intestinal bioavailability of iron ions, improve the iron absorption rate, enhance hematopoietic function, and effectively prevent anemia in infants.
2. Antibacterial and antiviral lactoferrin exerts antibacterial and antiviral activities in the intestine by directly acting on pathogens.
3. Promote the continuous maintenance of lactoferrin concentration in the small intestine of intestinal beneficial bacteria, thus promoting the reproduction of beneficial bacteria such as Bifidobacterium and Lactobacillus.
Now you know that lactoferrin is one of the main components of whey protein and plays a vital role in the baby's growth.
Breast milk is the best food for babies. The protein of breast milk is mainly whey protein, followed by casein. Whey protein can form a thin and soft curd in the stomach, which is easy to be absorbed. Its amino acid composition is very close to that of infants, so it can be used by infants to the maximum extent. In human milk protein, the ratio of whey protein to casein is about 8: 2; In protein, the ratio of whey protein to casein is just the opposite, about 2:8.
Therefore, for the healthy growth of the baby, the baby needs to add extra whey protein. Choosing a whey protein suitable for your baby's body is the best gift for your baby's growth.
Many mothers will ask, our baby is still so young, can we eat whey protein?
Studies have shown that oral whey protein is safe and reliable without any side effects. Therefore, adding whey protein to the baby can not only meet the needs of the baby's growth and development, but also protect the baby's health, which is particularly important for the nutritional needs of non-breastfed babies. Therefore, younger babies need more supplements.
Dear mothers, you must remember!
