Concerning levels of arsenic in chicken and mercury in fish may have adverse effects on the nervous system. The USDA has failed to safeguard the meat supply from drug residues, which may also be neurotoxic. Men who consume large quantities of meat may have an increased risk of getting muscle tremors due to the levels of cooked meat carcinogens known as heterocyclic amines.

Vegetarian’s Myelopathy refers to vitamin B12 deficiency. This can have potentially severe neurological consequences, such as spinal cord degeneration and paralysis. Those eating plant-based diets must ensure a regular, reliable source of vitamin B12. Supplements or fortified foods provide the safest, cheapest source.
