Well, this is a tricky question as the rate of DNA repair is dependent on many factors: the cell type, the age of the cell, the extracellular environment or even the part of the DNA damaged.
However, we know Plant-based diets have been associated with decreased DNA damage overall, slowed cancer growth, and possibly even slowed aging. This may be due to the high amounts of antioxidants in plant foods.
Also certain spices may be particularly beneficial in protecting against DNA damage such as turmeric, black pepper, ginger and rosemary.
Anyway, the science we want that will absolutely prove the absolute superiority of plant-based, spices, meditation and stress management don't exist yet.
What we know is that there are DNA repair enzymes that are produced in the liver.
These DNA repair enzymes require a sulfur substrate to function. Cruciferous vegetables provide this sulfur and help up regulate the production of these enzymes: cauliflower, cabbage, kale, garden cress, broccoli, Brussels sprouts and similar green leaf vegetables.
Based on Chinese Medicine's theories, chronification of any medical condition (e.g stress, pain, migraine, etc) increases the chances of causing damaging effects in your essence (or DNA) which might develop to genetic risks of their siblings.
