Studies have found that vegans and vegetarians have longer life expectancies on average when compared to meat-eaters. It is also seen that they grow old with relatively lesser health problems. For instance, people on a strict vegan diet are like to have better gut profiles with low amounts of gut bacteria and a high amount of protective species. Vegans also tend to have normal blood pressure and lower risks of heart diseases, diabetes, and cancer.
 
This is mostly because vegans include more fruits, vegetarians, beans, pulses, nuts, seeds, and whole grains in their daily diet to get the right amount of proteins and vitamins needed for their bodies. This means that vegans pay more attention to their overall health by maintaining a healthy and well-balanced diet. Besides, they also stay away from processed foods and meat products, which are often found to have carcinogen that causes cancer and many other health issues.
