Proteins Proteins , the whole world talks about proteins, which are often also called egg whites. One thing is indisputable: the body needs proteins. 0.8 – 1 gram of proteins per body weight is a rule of thumb. This means that a man weighing 80 kg needs on average 80 g of protein or a woman weighing 55 kg needs about 55 g of protein a day. It is up to you how you consume these proteins. Whether he/she takes in proteins via the respective diet or via dietary supplements is something everyone must decide for themselves.
Proteins are indispensable for the human body, because some amino acids contained in proteins cannot be produced by the human body, but must be supplied with food. Everyone is responsible for themselves and nutrition is very individual and depends on various factors. On the one hand, it depends on body size and weight and, on the other hand, on individual needs. An active person, a physically working person or even growing children may need a larger amount of proteins.
In short, proteins are amino acids and an important energy supplier. In addition, proteins are a vital building material that is required for many processes in the body. Among other things, proteins are essential for the growth and renewal of cells. Since the human body cannot produce numerous amino acids (essential amino acids such as leucine, tryptophan, isoleucine, lysine) itself, it is necessary to take them in with food.
Vitamin C is probably one of the best known vitamins and is often associated with citrus fruits, which are often mentioned as a source of the vitamin. Vitamin C is also called ascorbic acid and is involved in various processes in the human body. It is considered an...
Zinc is a vital trace element that the human body needs because zinc is involved in numerous processes in the human body. For example, zinc is involved in the immune system and cell growth. Zinc also supports the metabolism. However, the body cannot produce zinc...
Magnesium is a vital mineral that the human body needs because magnesium is involved in numerous processes. For example, magnesium is important for energy metabolism and muscle contraction. However, the human body cannot produce magnesium itself and must therefore be...
Depending on the protein, the composition of the respective amino acids is different, thus proteins differ greatly. A distinction is also made between vegetable and animal proteins. Another factor is the biological value, which means that the more similar the protein is to human protein, the higher the value.
Proteins are found in meat, eggs, fish, dairy products, legumes, whole grains and nuts. Furthermore, there are many protein powders, protein bars and more and more foods that are advertised with a high protein content.
Which food source an individual takes protein from is up to the individual and should be determined by each person. Opinions about proteins from food supplements vary widely. But one thing is indisputable, a lack of proteins can have negative consequences, among others a lack of proteins can lead to muscle loss. Conversely, many people, especially athletes, take proteins to build muscle. However, without training, it will not be possible to build muscle. Furthermore, people also try to lose weight by taking in extra proteins. This has not been scientifically proven. However, some protein sources, such as meat, also have a fat content that could stand in the way of the goal of weight reduction. So more and more people are turning to protein powders.
See if you are getting enough protein in your diet or not. If necessary, you should adjust your diet. It is up to you to decide whether you need protein from food supplements. According to common opinion, excess proteins are excreted in a healthy person.
