Cereal grains contribute to nutrient deficiencies, autoimmune disease, impaired digestion, and contain opioids which make them addicting. (1)

Switching from refined grains to whole grains causes zinc deficiency. (2)

Diets high in grain fiber deplete vitamin D stores. (3)

Phytic acid from whole grains block zinc and other minerals. (4)(5)

Removing grains, legumes, and processed dairy while increasing protein intake produces greater insulin sensitivity in animals and humans. (6)(7)

Brown rice (not white) prevents protein digestion and lowers nitrogen balance (a marker of muscle retention). (8)

Gluten and other grain proteins dysregulate the junctions between intestinal cells and increase cancer risk. (9)

80% of long term vegans are deficient in vitamin B12, which is needed for proper mental function.(10)

50% of long term vegetarians are deficient in vitamin B12. (11)

B12 deficiency causes dementia, cognitive impairment, depression, and degenerative mental disorders.(12)

Kids who eat a vegan diet can be deficient in B12 and have impaired brain function.  This reverses when they start eating animal products. (13)

Vegetarians and vegans have lower muscle creatine and carnosine levels. (14) (15)

The China Study is a collection of poor research and misinterpreted results. (16, 17, 18, 19, 20,21)

Grass-fed meat is higher than grain-fed meat in omega-3’s, CLA, TVA, vitamins, minerals, carotenoids, and antioxidants. (22, 23, 24, 25, 26, 27)

The longer an animal is fed grains, the fewer nutrients end up in its meat and other products it produces. (27)

Eating grass-fed meat boosts omega-3 levels more than can be explained by the amount of omega-3’s in the meat (grass-fed meat is better than omega-3 supplements). (28)

A lower ratio of omega-6 to omega-3 fatty acids reduces inflammation and protects against disease. (29)

Saturated fat is not associated with cardiovascular disease.  This is supported by almost every high quality observational study ever conducted (not that this really matters, since it’s observational data).  (30) (31)

Saturated fat does not raise cholesterol levels over time. (32)

Saturated fat raises HDL cholesterol, lowers triglycerides, and decreases the oxidation of cholesterol. (33, 34)

A diet high in saturated fat improves blood vessel function (don’t be fooled by the title of this study, read Chris Masterjohn’s take on what this study actually showed). (35, 36)

To get all the micronutrients your body needs from the USDA (DASH) diet, you would have to eat 33,500 calories a day. (37)

Vitamin D affects over 1000 genes in the human body. (38)

Magnesium deficiency exacerbates insulin resistance. (39)

Eliminating artificial colorings and food allergens improves ADHD symptoms. (40)
