It's not the ratios you need to be concerned with, it's the amounts. As
a rule of thumb, anyone eating at least 45 grams of protein a day from
sources other than gelatin and watermelon is safe, even if they have
active lifestyles. Except for sweets and greasy foods, all commonly
eaten vegan foods have "complete" proteins. Go to Walton Feed's website.
It has more details.
