I’ll fix that.
We cook our meat so therefore we weren’t carnivores. Meat consumption HAS contributed to longer life spans. Rabbit food is good for you. So what’s left is the carbs + the booze. Killers. Which goes to prove the good things in life are either illegal or fattening.
At some point we lost the ability to absorb vitamin B12 in the large intestine, where it is produced by gut bacteria, making man dependent on dietary sources of the vitamin (Schjønsby, 1989 Schjønsby, H. 1989. Vitamin B12 absorption and malabsorption. Presumably our ancestors were able to survive losing this ability because they were regularly consuming B12-rich meat.
Hominin skeletal remains from 1.5 million years ago show signs of porotic hyperostosis, which is generally linked to B12 deficiency and is virtually absent in chimpanzees who still obtain B12 from gut bacteria. Earliest porotic hyperostosis on a 1.5-million-year-old hominin, olduvai gorge, tanzania.
This provides some evidence that by at least the early Pleistocene meat had become so essential to proper hominin functioning that its paucity or lack led to deleterious pathological conditions. Earliest porotic hyperostosis on a 1.5-million-year-old hominin, olduvai gorge, tanzania.
Over time our capacity to convert the omega-3 fatty acid alpha-linolenic acid (ALA), found in plants, to the biologically important eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) forms (found primarily in seafood, but also in meat, eggs, and dairy. Dietary sources of omega 3 fatty acids became greatly reduced in comparison to other primates. The shift to energy-dense meat caused our guts, particularly our large intestines, to shrink significantly compared to those of apes. Gut proportions in humans are also adapted to meat eating. Our small intestine (in which most nutrients are extracted) comprises 56% of total gut volume, while the large intestine comprises about 20%these proportions are reversed in apes.
Meat eating, and the concomitant reduction in size of the energy-consuming gut, is believed to have played an essential role in the increase of brain size in the hominin lineage. Because the brain and gut compete for energy, the former was able to increase in size when the latter became smaller.
I had 5 meatballs last night. Made from hambuger, pork, italian sausage. 1/3rd apiece. Is that cutting back?
My grandson is in the lower class for height and weight in his class. My daughter has good intentions, but salad for dinner and not milk for cereal is not for kids.
