Biology Forum › Human Biology › Veganism and protein
August 26, 2007 at 3:17 am #8132
It’s certainly not permanent, but just temporarily (until I look into the process better), I’m a vegan. Is drinking soy milk a sufficient supplement? Can I realistically build muscles at the same rate as eating meat? Is it unhealthy to be a vegan?
Thank you for any information.

anything with the word protein does not make it eligible to replace all other sources of protein.
for example vicilin is the major protein in pea ; it contains 7% lysine but no sulphur coniatining amino acids methionine and cystein.
but sunflower seed protein has 23 % methionine + cysteine.
same way there are many examples in which one source of protein has certain amino acids in large quantity but lack totally in other amino acids.
and if the amino acids which is lacking is classified as essential amino acid ( need to be taken from outside as our body cant manufacture it), so it wont be advisable to depend fully on one source.
so uh ave to check out the type of amino acids ( should have all esential amino acids) and its quantity.

Ok. I’ll check back later. Thank you for looking into it.

As the Japanese and Chinese found out thousands of years ago the protein in soy is not available / digestible for the most part in soy unless it is cultured. Holistic nutritionists are recommending doing as has been done before agribusiness took over our diets – soak grains and legumes at for 24 hours before eating so protein etc. is available. (bacterias need to break down outer coatings first). Tofu and tempeh are cultured soys so products from them should be digestible.
I recommend rice and nut milks for best nutrition. Check this out for yourself, don’t listen to all the authorities. See how your digestive system feels after each, (and everything for that matter.)

Lack of protein is not the only problem. You should get vitamin B12 injections regularly.
Or an easier and-in my opinion- better solution: Try to eat meat.

As many ancient, tried and true cuisines (that have supported millions without all the ailments we have) have found, complete proteins can be easily found outside of eating animals.
Although there are enzymes, and B12 that must be carefully accounted for the health and spiritual benefits of not eating animals have been touted for thousands of years. Although easy to eat what is provided for us with our current food supply system, other options are well worth aspiring to.

Look on any animal rights activist site and you’ll find a complete breakdown of what nutrients you need and how to makeup for it. Only thing I’d caution is feeding a vegetarian solution for babies…that usually ends up with malnutrition.

At at times death are this year’s US news agencies reported. But that’s an extreme case.

Thanks for the insight. I just started biology and looked up "vegetarianism" in the text book. It says there are 20 amino acids and the body can’t produce 8 of these. It states that vegetarians should combine 2 or more plant products to achieve all 8. It states supplements are not recommended by most nutritionists but it doesn’t seem to be calling plants a supplement. It seems to suggest plants are an authentic source with real amino acids (and the right ones).
A vegetarian diet is, according to my text book, supposed to be sufficient. Veganism, on the other hand, is nowhere in the book. I know soy milk has calcium. I guess the question really comes down to: Is soy milk a sufficient alternative to milk?
(I’m guessing it’s even healthier.)
