my comments on a vegetarianism blog

The vegetarianism blog is here: http://www.lsdesigns.us/apps/blog/show/7636236-what-s-the-beef-with-eating-meat-a-discussion-in-favor-of-vegetarianism

Lard (saturated fat from meat) has been shown to decrease learning ability in rats.*
Eating fats triggers the release of endocannabinoids which make you want to eat more fats.**
Serotonin regulates appetite such that increasing serotonin levels decreases obesity. Insulin promotes the production of serotonin and is secreted in response to eating fats and glycemic loads.***
Mice that cannot secrete serotonin outside the nervous system have diabetically low levels of insulin secretion. Researchers found that serotonin blocks the secretion of insulin by the pancreas. This suggests that the unregulated release of insulin in the absence of serotonin quickly depleted the mice's insulin and nutrients for making insulin.****
Food derived from grain-fed animals is high in omega-6 acids. An intake of omega-6 acids in too high a ratio to omega-3 acids can cause brain damage, heart disease and cancer.***** Flaxseed oil is the best source of some omega-3 acids, but the most potent omega-3 acids are derived from fish or algae.
