vegan diet benefits digestive system

Arguments

1. Animal products often give people food poisoning. Meat, seafood, eggs and milk provide the ideal breeding grounds for bacteria such as Campylobacter jejuni (associated with poultry products), Escherichia coli 0157:H7 (ground beef), and Listeria monocytogenes (dairy products). Other less common pathogens included Bacillus cereus, Clostridium botulinum, Clostridium perfringens (found in beef), Shigella, and Staphylococcus aureus (found in pork).
2. Diets which contain a large amount of meat and little fibre encourage colon cancer. Meats contain fat which requires the body to produce bile to digest. Meats are a medium for the growth of bacteria which can convert bile into carcinogenic substances. Diets high in fruits and vegetables, especially cruciferous vegetables, discourage the development of colon cancer
3. The accumulation of toxins from the recycling of animals into animal feed
4. Vegetarians have 40% less chance of developing bowel cancer
5. Animal Products are prone to bacterial and viral infection and parasitic infestation, leading to human illness
6. A diet rich in fruit and vegetables provides a complete and healthy diet for humans
7. Phytochemicals
8. Antioxidants
9. Vitamins and Minerals
10. Fibre
11. Bio-Accumulation of environmental toxins and poisons occurs in animals (at the top of the food chain)
12. Vegetarians have lower risk of constipation
13. Vegetarians have lower risk of Peptic Ulcers
14. Vegetarians have lower risk of Diverticulitis
15. Vegan diets high in complex carbohydrates and low in simple sugars (fruit sugars are OK) can help prevent the development of hypoglycaemia and treat the problem once it has occurred. Diets high in fat exacerbate the problem and diets high in protein tend to be associated with high fat.

Objections

1. There is no Vitamin B12 in plant foods
2. There is no Vitamin D in plant foods
3. Non-Haem Iron is less readily absorbed than Haem (Animal Derived) Iron
4. Humans Need Protein to Develop and Repair Tissue and there is lots of protein in animal products
5. Cows milk is a good source of calcium
