Vegan and Vegetarian Diets – Disadvantages and Dangers

vegan and vegetarian diets – disadvantages and dangers

Vegetarian and vegan diets have many disadvantages and even might be dangerous, especially if are being followed for a long period of time.

  • Vegetarian and Vegan diets cause a deficiency in levels of vitamin B12. This becomes important when you realize that vitamin B12 deficiency results in a condition called hyperhomocysteinemia, which is extremally oxidative. This explains the rise in stroke risk amongst vegetarians and vegans.
  • Vegans suffer from protein malabsorption and amino acid deficiencies, which can be health-threatening. This also explains the fact, that most of the vegans are underweight and can’t develop muscle mass (without using supplements).
  • Vegetarian diets produce massive imbalances in the ratio of omega-6 to omega-3 fatty acids in the body. This constant supply of pro-inflammatory agents may be what ruins the immune system in their bodies.
  • Vegetarians and Vegans have much higher levels of advanced glycation end products which are a risk factor for kidney disease and atherosclerosis, and also Alzheimer’s disease. This may explain why large epidemiological studies noted an accelerated cognitive decline in vegetarians.
  • Vegetarians and Vegans usually have a deficiency in these minerals: zinc, iron, selenium, calcium, and iodine. This explains their increased risk of bone fracture.
  • Vegetarian and Vegan diets don’t even protect against any type of cancer. It’s a widely spread myth. If you maintain healthy body fat levels, you’re just as “defended” from cancer.

Each of this disadvantages can be solved by eating some animal source protein. Even if you want to lower cholesterol levels (which is a complicated and misunderstood topic, that I will explain in one of the next articles), it’s more effective to add animal protein to your diet than vegetable proteins, which aminogram is incomplete.
