&gt;So yes, it is theoretically possible to eat complete and healthy without meat. It&#x27;s also theoretically possible to put 3 chop sticks on top of each other, put them on your head and walk like that to your super market. That doesn&#x27;t mean you can do it, by adding some beans and nuts to your diet. It&#x27;s so complicated that some doctors think they can&#x27;t do it for a long time to themselves.<p>This is such FUD nonsense; pretty deplorable on this forum. There&#x27;s nothing theoretical about eating &quot;complete and healthy without meat&quot; -  people have been living on vegan and vegetarian diets for centuries without ill effects. People have become bodybuilders, MMA fighters while being vegan too, not that the vast majority of humans need to measure their diets by those of elite athletes.<p>As for &quot;so complicated&quot; here is the American Dietetic Association:<p>&gt;It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes.<p>[0]<a href="http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;19562864" rel="nofollow">http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pubmed&#x2F;19562864</a>
