What is the difference between HBV and LBV protein?

HBV (High Biological Value) Proteins contain all the essential amino acids in the correct porportions. Proteins of HBV are ususally of animal origin. One exeption is soya beans which has HBV proteins.

LBV (Low Biological Value) Proteins are foods that lack one or more essential amino acids. LBV proteins are found mainly in plant food. One exeption is gelatine which is obtained from an animal source.

The two main meat groups (white meat and red meat) are split between HBV and LBV as white meats such as chicken fit better into the HBV range where as lamb and beef have a tendancy to lack in certain amino acids making them LBV (meats). although still HBV red meats are less good for you due to there higher probortion of saturated fats
