Are human beings anatomically more similar to natural carnivores or to natural herbivores? Let’s find out….
Intestinal tract length. Carnivorous animals have intestinal tracts that are 3-6x their body length, while herbivores have intestinal tracts 10-12x their body length. Human beings have the same intestinal tract ratio as herbivores.
Stomach acidity. Carnivores’ stomachs are 20x more acidic than the stomachs of herbivores. Human stomach acidity matches that of herbivores.
Saliva. The saliva of carnivores is acidic. The saliva of herbivores is alkaline, which helps pre-digest plant foods. Human saliva is alkaline.
Shape of intestines. Carnivore bowels are smooth, shaped like a pipe, so meat passes through quickly — they don’t have bumps or pockets.
Herbivore bowels are bumpy and pouch-like with lots of pockets, like a windy mountain road, so plant foods pass through slowly for optimal nutrient absorption. Human bowels have the same characteristics as those of herbivores.
Fiber. Carnivores don’t require fiber to help move food through their short and smooth digestive tracts. Herbivores require dietary fiber to move food through their long and bumpy digestive tracts, to prevent the bowels from becoming clogged with rotting food. Humans have the same requirement as herbivores.
Cholesterol. Cholesterol is not a problem for a carnivore’s digestive system. A carnivore such as a cat can handle a high-cholesterol diet without negative health consequences. A human cannot. Humans have zero dietary need for cholesterol because our bodies manufacture all we need.
Cholesterol is only found in animal foods, never in plant foods. A plant-based diet is by definition cholesterol-free.
Claws and teeth. Carnivores have claws, sharp front teeth capable of subduing prey, and no flat molars for chewing. Herbivores have no claws or sharp front teeth capable of subduing prey, but they have flat molars for chewing. Humans have the same characteristics as herbivores.
But aren’t humans anatomically suited to be omnivores?
Nope. We don’t anatomically match up with omnivorous animals anymore than we do with carnivorous ones. Omnivores are more similar to carnivores than they are to herbivores.
人类在解剖学上更类似于天然肉食动物还是草食动物呢?我们一起去弄明白……
肠子的长度.肉食动物肠管的长度是自身体长的3-6倍,而草食动物是10-12倍,人类的比率类似于草食动物.
胃酸.肉食动物胃脏酸性20倍于草食动物,人类胃酸接近于草食动物.
唾液.肉食动物的唾液呈酸性,为了协助预先消化植物性食物,草食动物的唾液呈碱性,人类的唾液呈碱性
肠子的形状.,肉食动物的肠子平滑,形状类似于管子,因此肉食可以迅速地通过-------他们没有凸起或凹陷,草食动物的肠子凹凸不平,像装了诜多口袋,像有风的山路,因此植物性食物会缓缓地通过,是为了最充分地吸收营养..人类的肠子有着与草食动物类似的特征.
纤维素,肉食动物不需要纤维来帮助食物穿过它们又短又光滑的肠管,而草食性动物则需要纤维来帮助食物穿过它们长而凹凸不平的肠管,以防肠子被腐烂的食物堵塞.人类有着与草食动物一样的需要.
胆固醇.对于肉食动物来说,胆固醇不是什么问题,肉食性动物比如一只猫,可以保持高胆固醇的饮食习惯,而不会对健康有害.一个人则不然,人类在饮食上对胆固醇是零需求,因为我们的身体自己会制造所需的全部胆固醇,胆固醇只存在于肉类食物中,在植物类食物中是没有的.以素食为主的饮食习惯是由对胆固醇的零需要来定义的.
爪子和牙齿.肉食动物有爪子,和易于捕捉猎物的尖利的前牙,而没有用于咀嚼的平坦的臼齿,草食动物则没有爪子和尖利的前牙,但是却有用于咀嚼的平坦的臼齿,人类有着与草食动物一样的特征.
但是在解剖学上难道人类与杂食动物不相配?
对,在解剖学上我们不再把与肉食动物作比较那样,同与杂食动物作匹配了,肉食动物与草食动物相比,杂食动物更类似于肉食动物
