Rabbi Yoel Schwartz (Jerusalem Court for Bnei Noah)

The consumption of food should be mainly for health value. It is worthwhile though that a person should enjoy the food he eats since then the food is digested properly. There is also a spiritual value. If there is plenty of food on the table and it tastes good, a person feels and recognizes the grace of G-d. Food should be consumed to be healthy and not just for enjoyment. Therefore a person must ensure his good health in everything that is connected with his diet. This includes a naturalist.
