  • What is whey protein?

    Whey Protein is made from milk and contains all essential amino acids. It is digested quickly and readily available to muscles. This makes it a popular choice for athletes immediately after a hard session when they are most receptive to repair and growth.

  • What is casein protein?

    Casein Protein is made from milk and contains all essential amino acids. Where it differs from whey protein is the rate at which it is digested and absorbed. Casein is absorbed 4 times slower than whey, which makes it an ideal protein to consume before going to bed. This may result in efficient building, repair and maintenance of lean muscle mass.

  • What’s the difference between whey and casein?

    Whey and casein both come from milk and contain all essential amino acids. The key difference is the rate of absorption. Whey proteins provide the highest biological value of any protein as your body absorbs and uses whey protein more effectively than other protein. Casein is digested more slowly and tends to be consumed before bed when athletes are trying to maintain muscle mass.

  • When should I use protein powders?

    Protein powders should be used to provide nutrients that your food diet does not provide. If you consume adequate amounts of protein through your diet, protein powders may not be necessary. Scenarios when protein powders are useful are when access to quality protein is limited, such as during travel, or recovery from heavy exercise is a priority and food sources of protein are limited.

  • Should I follow a high protein diet?

    High protein diets are growing in popularity but are often taken to extreme. A protein rich diet is important, including regular feeding of protein throughout the day, maybe in 4-6 meals. This is especially important in research currently emerging in ageing populations. As ever, it is important to ensure that increased protein does not replace other vital nutrients in the diet. In summary, it is a protein rich diet that is required, NOT a high protein diet per se. Protein itself does not remain a magic bullet on its own.

  • How do you measure the quality of a protein?

    One method is to look at the biological availability of a protein, i.e. the amount of protein absorbed and used from a protein source. Proteins from certain foods are worth more than the same amount from other foods. All proteins are ranked in terms of their biological value. Eggs, cows milk, fish, chicken and beef have the highest biological value.

  • What are amino acids?

    Amino acidsare the building blocks of proteins. There are 20 different amino acids but only 8 of these are essential. These amino acids have to be ingested through food every day. Amino acids are involved in nearly every bodily function.

  • Are animal sources of protein better than plant sources?

    Animal sources of protein are complete proteins. They contain all essential amino acids. Animal sources of protein are generally considered high fat so it’s best to choose lean sources such as fish, turkey and chicken the majority of the time. On the other hand, plant sources of protein are incomplete proteins. They tend to be missing one of more essential amino acid. To achieve a balanced amino acid intake, a variety of sources of plant proteins need to be eaten throughout each day. Plant proteins have the benefit of being high in fibre and low in fat.
