Can a vegan diet slow the pace of ageing?

A study conducted by the Stanford Prevention Research Centre found that a vegan diet can slow the pace of ageing. 

Researchers studies 21 pairs of identical twins with one half of each pair asked to eat an omnivorous diet and the other a vegan diet for a period of eight weeks. For the first four weeks they had their meals prepared for them, then they made their own food for the remaining period of the study. 

The outcome of the research was that ‘significant’ differences in the impact of ageing on the two groups were displayed. However, it was also noted that the vegan group lost more weight, which itself may have been a contributory factor.

It should be noted there are health risks associated with a vegan diet, such as nutrient deficiency, bone health and digestive issues. The full study is available here:-
