Vegan Diet; Deficiencies
A strict vegan diet can lead to deficiencies in nutrients such as vitamin B12, proteins and zinc - these can cause fatigue and anaemia. However, this effect can be avoided by the use of concentrated foods such as brewer's yeast, bee pollen, spirulina, blue-green algae, chlorella, or by taking supplements. Another way to avoid prtein deficiency among vegans is to eat the correct plant protein combinations, for instance, by combining grains and legumes at the same meal and in the correct proportions to yield usable protein. Soya products such as miso and tofu are also helpful in creasing protein intake.
