It"s important to note that there is no requirement at all for animal protein in the diet. There is plenty of protein in beans, grains and vegetables, as well as the concentrated protein in seitan ("wheat meat") and soy products, such as soymilk, tofu, tempeh and various meat substitutes, all of which are found in any natural food store or in the health-food section of grocery stores.
Decades ago, nutritionists thought that only meat provided "complete" protein - meaning all essential amino acids - while plant foods had to be carefully combined to provide all the necessary amino acids. The fact is, a varied plant-based diet provides complete protein without any special combining.
－－－－－－－－－－－引起我们重视的事情是，饮食中完全没有必要加入动物性蛋白质。在豆类、谷类、蔬菜和seitan的浓缩蛋白质（大麦做的肉)、大豆制品（豆奶、豆腐、印尼豆豉及各种肉类替代品)中已含有足够蛋白质，这些食物都能在天然食品店或杂货店的健康食品区找到。
几十年前，营养学家认为只有肉类才能提供“齐全”的蛋白质，即提供所有必需的氨基酸，而吃素食则要绞尽脑汁地进行搭配才能提供人体所需的氨基酸。事实是各类丰富的素食食谱并不需要任何特别的搭配就能提供齐全的蛋白质。

－－－－－－－－－－－seitan是面筋。下面有说怎么做面筋。我平时做面筋就用此法-先和成面团再用水洗。我在健康食品店里见到有卖wheat gluten的，有时间买来试验一下。

Wheat gluten, also called seitan (pronounced SAY-tahn), wheat meat, wheat-meat, wheatmeat, gluten meat, or simply gluten) is a foodstuff made from wheat gluten. It is made by washing dough made from wheat flour in water until the starch is rinsed away, leaving only the gluten, which can then be cooked and processed in various ways.
－－－－－－－－－－－回楼主：不客气。如果还有资料我可以帮忙的尽管说。
－－－－－－－－－－－中国人现在的膳食情况是蛋白质摄入过多，引起多种疾病

素食主要是取食物精气（得天地日月辅育而成)，西方人分析的蛋白质仅属形，可见
