Summary: Very little
Insects also provide the same critical class of nutrients as the animal kingdom.
"... all of the great ape groups take in some animal protein ... by consuming insects, insect eggs and the larvae that nest on the plants and fruits they eat."
"... chimpanzees kill and eat monkeys and make a tool to extract termites from their hills (homes), and that they went to considerable effort to obtain these foods ... meat is the only food they share with other chimpanzees."
"... tried to breed the near extinct fruitivorian South American golden marmoset in captivity with no result, but when a little animal protein was added to their diet, they began to breed, which proves that they require a small amount of animal protein to be healthy and reproduce"
"It was the quest for meat that led
Homo sapiens to [develop stone tools and to] colonize the world. They followed the herds of animals. When overpopulation caused the animal food supply to dwindle, many moved on, from tropical Africa to North Africa, Asia, Europe, the Americas and Australia. They walked and adapted to the cold climates and were able to do so because
meat is compact energy, and one kill of a mammoth or other big game could feed many people and lasted for a long period of time; whereas gathering plants and fruits to eat was seasonal. Until the early part of the 20th century there were peoples who lived almost entirely on animal food. For example, the Eskimos of North America and Lapps of Scandinavia lived almost entirely on animal protein and were very healthy."
"However, when we refer to meat, remember that meat entails fats which are necessary for sound health. The protein and minerals in the meat cannot be utilized without the nutrients in the fat."
"Humans only turned to plant foods as major food sources when, due to the ever-increasing human population, herds of animals became scarce. They learned to domesticate some animals and invented agriculture."
"... grains cannot be eaten raw... when humans began eating a diet high in grains, the incidence of tooth decay increased considerably. Tooth decay increased
dramatically when refined grains (wheat and rice) became staple diets ..."
"For normal growth and sound health throughout life, the human species requires eight amino acids which their bodies cannot manufacture, vitamin B12 and some essential minerals. The only viable source of these amino acids and of vitamin B12 is animal protein such as red meat, fish, shell fish, eggs, milk, insects and worms."
"...kwashiorkor is a deficiency disease which impedes the normal development of vital brain cells and stunts growth. People may be getting all they need to eat to satisfy their hunger from grains and other plant foods. They may even become plump on a diet of grains, but their normal growth and development is stunted."
"Unlike humans, the digestive tract of gorillas is equipped to manufacture the essential amino acids and other vital nutrients. The human digestive system is not so equipped and we must rely on animal proteins."
"the prohibition of pigs (pork) by the Jewish religion and cows by the Hindu religion came about due to the ever-increasing pressure of population growth. Pigs eat grain. It takes lots of land to grow grain for wheat which could feed more humans than it could feed pigs that require the grain to become meat on the human dinner-table."
"Likewise, in India where beef was widely eaten at an earlier time in history, the Hindu religion prohibited it because the cow was more valuable for its milk and dung [fuel for cooking fires] than as edible beef."
"In economically diverse societies where animal protein is scarce among the poorer classes and more abundant in the increasingly affluent sectors of society, it is interesting to note the differences in body height that seems to reflect the way people are forced to eat. The less affluent sectors subsist primarily on grains and a few vegetables and lack the height that is found among the more affluent ruling classes" [that can afford meat.]
