Why Whey Protein?March 2023 March 2023 Share Link Close share Copy link Whey protein is a complete protein that contains all the essential amino acids. But why should you add it to your diet? When you follow a healthy lifestyle, counting calories and watching your sugar and salt intake have probably become second nature. But a lot of people do not realise the importance of ensuring that your body gets the protein it needs to flourish. Protein is essential to grow and repair various cells. An easy way to ensure that your body receives the protein required to thrive is to add whey protein to your diet. What is whey protein? First things first: what is whey protein? Milk consists of two proteins, namely casein and whey. The milk processing results in a remaining liquid called whey when making yogurt or cheese. Therefore, if you ever see a watery liquid on top of yoghurt, do not throw it away, as it is a nutritious source. Whey protein and amino acids It is a complete protein that contains all the essential amino acids. But what are amino acids, and why is it important? Amino acids are molecules that combine to create proteins. These molecules contain 20 organic compounds, which we categorize as non-essential or essential amino acids. Your body produces non-essential amino acids, so you don't need to add them to your diet. However, your body cannot produce essential amino acids (EAAs), so you must add them to your diet. From a fitness point of view, amino acids can help to repair damaged muscle and build new muscle, while from a health and wellness perspective, amino acids can help to regulate the immune system, assist with calcium absorption, encourage skin elasticity, and assist with the synthesis of neurotransmitters and hormones. Why add whey protein to your diet? Contrary to what many people believe, whey protein isn’t just for athletes and fitness enthusiasts. Many rely on whey protein to help meet their daily protein needs, lose or gain weight, or recover from an injury or surgery. You can therefore add this to your diet, even if you do not exercise daily. The benefits of adding whey protein to your diet are listed below: It can help with weight loss An increase in protein intake can positively affect weight loss, as it reduces your level of the hunger hormone known as ghrelin. It also helps you feel fuller for longer, reducing cravings and preventing you from snacking. Whey protein is very digestible and gets absorbed from your gut quicker than other protein sources. It can promote muscle growth Protein is the building block of muscles; eating adequate amounts of protein helps you maintain your muscle mass and promotes muscle growth during strength training. It is rich in the branch-chain amino acids known as leucine, the most growth-promoting (anabolic) of the amino acids. Leucine also helps to prevent muscle breakdown and encourages muscle recovery. It can promote healthy skin, nails & hair Since protein is one of the key building blocks of skin tissue and supplies the body with the essential amino acids required to make keratin, it is evident that it will help with healthy skin, nails and hair. The different types of whey protein There are three types of whey protein, namely concentrate, isolate, and hydrolysate. These types have different protein, lactose and fat contents. Whey protein concentrate Concentrate is the least processed form of whey protein and therefore keeps the health-promoting nutrients that are naturally present. This form comprises low levels of fat and carbohydrates. The percentage of protein in concentrate depends on how concentrated it is. Whey protein isolate Is further processed to remove most of the carbohydrates, lactose and fat, and usually contains at least 90 percent protein. Whey protein hydrolysate Hydrolysate is viewed as the ‘pre-digested’ form as it has already undergone partial hydrolysis (a process required for the body to absorb protein). Hydrolysate is the easiest for the body to digest, resulting in a sharp rise in blood insulin levels, which can encourage lean muscle growth.
