FitnessProtein powder: food source of protein
Protein is one of the most important macronutrients that make up life. Our daily protein mainly comes from animal foods and plant foods.
Animal and vegetable proteins
The amino acids contained in animal protein and plant protein are different, which means that their nutritional value is also different.
Animal protein is mainly derived from meat, eggs and milk from poultry, livestock and fish. Its protein composition is mainly casein (78-85%), which can be better absorbed and utilized by adults. More importantly, animal protein has a complete range of essential amino acids in a reasonable proportion, so it is easier to digest, absorb and utilize than ordinary plant protein, and its nutritional value is relatively higher.
Plant-based protein Mainly comes from rice, noodles and beans. The nutritional value of protein is relatively low, but plant-based foods do not contain cholesterol and are more economical.
The following will introduce to you the best representatives of animal protein and plant protein:
Whey and soy protein
whey protein)
A complete protein extracted from fresh milk. Contains a complete group of essential amino acids for the human body, with a high-quality protein content of more than 80%, mainly composed of β-lactoglobulin, α-lactalbumin, bovine serum albumin, immunoglobulins, lactoperoxidase, lysosomes, lactoferrin, etc. It is currently recognized internationally as one of the most nutritionally comprehensive natural proteins and is also our first choice for protein supplements, especially for those who want to gain muscle and fitness.
Soy protein
Among the many plant-based proteins, the one with the highest nutritional value is soy protein (also known as soy protein), and soy foods do not contain cholesterol, which is a characteristic that animal foods do not have. Unprocessed soy protein has its drawbacks: It contains relatively little methionine, an essential amino acid. However, because soybeans have high protein content and do not contain cholesterol, soybean protein powder is widely used by people.
Soy protein isolate contains eight essential amino acids, similar to meat, fish, eggs, and milk, and is a complete protein. Soybeans are very beneficial in terms of heart health, preventing osteoporosis and relieving menopausal symptoms in women. Reduce plasma cholesterol and prevent the occurrence of cardiovascular diseases; replace animal protein and reduce the burden on the kidneys of diabetic patients.
