You Should Avoid a Vegetarian Diet
Meat is a High Density Food.
Organ meats, meats, fish and shellfish, are among the most nutrient-dense foods you can eat.
Even when eating meat and animal fat, people have trouble getting a full range of vitamins and minerals, that's why we should try to eat animals from "nose to tail."
In our society, people are often reluctant to eat organ meats. Those are super foods, and frequently they are cheap to buy.
Protein Deficiency in Vegetarians
The quality of protein in many vegetarian diets is poor. In vegan diets it's commonly disastrously poor. Soy protein, nuts and seeds, deliver poor levels of the amino acids taurine, cysteine, carnitine and methionine. This makes if difficult for the body to rebuild itself well. (Dr L. Wilson will add, that these amino acids are essential to the liver to enable it to detoxify heavy metals from the body. I'm not sure of that as science.)
Vitamin Deficiency in Vegetarians
B12 deficiency is especially common in vegetarians, causing fatigue, lethargy, weakness, memory loss, plus neurological and psychiatric problems.
68% of vegetarians and 83% of vegans are B12 deficient, compared to just 5% of omnivores.
The two fat-soluble vitamins: A and D, are commonly lacking. Fat-soluble vitamins play numerous and critical roles in human health.
Vitamin A promotes healthy immune function, fertility, eyesight and skin.
It's nearly impossible to get enough vitamin A from plant foods without juicing or taking supplements.
Vitamin D regulates calcium metabolism, regulates immune function, reduces inflammation and protects against some forms of cancer.
Vitamin D levels are 58% lower in vegetarians and 74% lower in vegans than in omnivores.
Well Known Vegetarian Diets
Nathan Pritikin advocated that 80% of your diet should be carbohydrates. Senator George McGovern lost weight following the Pritikin Diet.
Dean Ornish developed his diet based on Pritikin's key ideas. He was very strict about it.
Ornish Diet: No red meat, no liver, butter, cream or eggs.
Mostly fruits, vegetables and grains.
Dean Ornish was called "the healer of hearts." The Anti Coronary Club picked up Ornish's key ideas.
People found it very difficult to keep to the Ornish Diet.
One research study found that people on the Ornish diet developed wider arteries. This was considered a success.
It's also said that the blood supply to the heart increased from 10% to 15%
