Want this question answered?
The biological value (BV) of a protein is a measure of how much of the protein is retained and used in the body. A protein which has a high proportion of essential amino acids ie ones which we cannot synthesise ourselves, will have a high biological value (eg 0.9 - 1.0). A protein with a low content of essential amino acids will have a correspondingly low BV.
The protein RDA assumes that dietary protein is from a mix of low- and high-quality sources.
Proteins with a low biological value are proteins which do not significantly result in growth by the individual that eats them. This is usually because the amino acids in the protein are not all present in the right amount. Foods with proteins that have low biological value include almost all plants. For example, cereal grains are low in the amino acid lysine, and so have low biological value by itself. Legumes are low in methionine. The plant with the highest biological value protein is quinoa.
The biological value (BV) of a protein is a measure of how efficiently the body can use the protein for growth and maintenance. Proteins with high biological value contain all the essential amino acids in the right proportions and are easily digestible, while proteins with low biological value may lack some of the essential amino acids or be harder to digest. The differential between the low and high biological value can vary depending on the protein source. For example, animal-based proteins such as meat, fish, eggs, and dairy have high biological value due to their complete amino acid profile and easy digestibility. In contrast, plant-based proteins such as legumes, grains, and vegetables may have a lower biological value due to their incomplete amino acid profile and lower digestibility. The differential between the low and high biological value can be important for individuals who need to consume sufficient amounts of protein for optimal health and fitness, such as athletes or people with certain medical conditions. Consuming a variety of protein sources can help ensure a balance of high and low biological value proteins in the diet.
well ....Low biological Value is where you are missing a serten amino acid in your diet :) there are 22 amino acids and only 6 of them are important :D thankyou for taking in mt answers :) x
Animal sources tend to be higher biological value protein than plant sources, as animals' needs are closer to those of humans than the protein requirements of a plant. Eggs and milk contain high biological protein because they are the only sources of nutrition for the relevant young animals so they must contain all of the proteins necessary. Meat, fish and other animal sources are good srouces of protein, as are soya beans, nuts, cheese and then vegetables such as potatoes, peas adn also hummus.
Yes, protein sources can replaced your daily diet to some degree with low purine protein sources such as milk, cheese eggs, and nuts.
The key to a good low carb meal is two fold: choose good carbs, and low fat sources of protein. Good carbs include whole wheat pasta, grains and vegetables. Good protein sources include beans, eggs, chicken and pork.
meat, bread, and fish are great sources of protein... WOW thanks but the question was asking for sources of WHEY protein???
If you are a female, information on low carb high protein diets can be found at http://women.webmd.com/guide/high-protein-low-carbohydrate-diets, and if you are a male, this information can be found at http://men.webmd.com/features/low-carb-high-protein-menu. These websites are highly trusted, factually correct sources for all things health-related.
That is not an easy requirement, since most foods that are low in carbohydrates do contain some cholesterol. However, I can recommend raw celery, and mushrooms (but not sauteed mushrooms, that would add cholesterol).
