The heavy dependence on these resources shows that meat production at this level to sustain the ever growing population is simply not sustainable. The use of land and energy and resources required to sustain a meat-based diet is far more than that for the vegan diet US Department of Agriculture, (2001). The principle defining why the vegan diet is more energy efficient than the meat diet is naturally at each stage of energy exchange between all trophic levels there is a loss of energy as no exchange is 100% …show more content…
Professor A. Jackson (2011) For many years now myths have surrounded the vegan diet suggesting that it is incomplete of essential amino acids, and thus one must consume red meat in order to have a balanced diet. The RDA recommends we consume 0.8 grams of protein for every Kg that a person weighs. Food and Nutrition Board, Institute of Medicine. (2002) Proteins consists of amino acids, these are often referred to as its building blocks. Human beings have a biological requirement for amino acids and cannot synthesise 9 of the 20 most common. These 9 are called the essential amino acids and must be a part of our diet in order to make all the necessary proteins. Red meat has high amounts of these essential amino acids and is traditionally considered a good source of protein for this reason. It is a myth that a varied vegan diet does not also contain these amino acids but it is true that they are in lower amounts in vegan staples. For example grains are low in lysine and legumes are low in methionine two essential amino acids, but they are all present and can be consumed in the necessary volumes in order to have the right amount of amino acids in one’s diet.
