Studies have shown that a natural way of avoiding salmonella infections is through vegan diets. The E. coli infection is similar to salmonella food poisoning. This infection comes from the digestive organs of animals. However, switching to vegan diets is a surefire way of preventing salmonella.

However, the vegan diet is a relief for obese children.
