A well calculated vegan diet can provide us with all the nutrients our body needs. Both the British Dietetic Association and the American Academy of Nutrition and Dietetics recognize that vegan diets are suitable for every age and stage of life. 
Researches have linked the vegan diet to lower blood pressure and cholesterol and lower rates of heart disease, type 2 diabetes and certain types of cancer. Also, becoming vegan is a great opportunity to learn more about diet and cooking and, ultimately, to improve your eating habits. Getting your nutrients from plants allows more room for healthy choices, such as whole grains, fruits, nuts, seeds, and vegetables, which are high in fiber, vitamins, and minerals.
