A meat diet is only unhealthy if one consumes excessive meat , thats why we need to eat foods in consideration , plus our bodies body requires 32 branched-chain amino acids(BCAA) , our body can produce all BCAA's except 8 of them ,which we can aquire only by eating meat, BCAA are smaller molecules of protein , therby which if you don't consume all amino acids means you probably have protein deficiency, plus vegan diets mostly contains a variety of vegetables and since thats the case , they'll need to think of other ways to make their foods tasty , once such way is deep frying , as u can see in most hawker centres , stalls usually sell 3or more fried vegan products , and even if it is not deep fried , you still need heavy seasoning and sauces to enhance the taste of the food. If you think you can get most of your protein sources from soy , you are wrong instead soy product are rumoured to have estrogen producing results ( female hormones) which means if you consume in excess and your estrogen's ratio overpowers your testorone hormones( male hormones) your body will start to lean towards the female way of growing , much fried and soy foods will cause storage of fat in the chest and buttocks area , thus causing vegans to be unhappy about their body and may turn to comfort foods in order to feel better . Comfort foods = foods eaten in large amounts or junk foods like ice cream and/or chocolates , candies ,etc. If this is the case , then a vegan diet is certainly not more healthy or as healthy as a diet containing meat.
