The best way, is to feed that person and remove his hunger and lust, however if unsure as to who is lusting for your food, then there are some Totke, which are practiced in most parts of India for removing Nazar Dosh from food. One such Totka, which is simple to practice and believed to remove Nazar Dosh from food, is explained by me in this post.
If it is suspected that the Food is affected by Nazar Dosh, and then a little portion of each of food items has to be taken on a large Banana leaf or a Patravali, known is South India as Vistaraku, which is a disposable serving plate made from large died leaves of trees like Banyan. A pinch of Gulal Powder has to be put on each of the food items and then the Patravali or Banana leaf has to be kept on the road. This is said to exorcise the Evil or Malefic Eye from the food and it can be safely served to the family members or guests.
