Can a person eat the food that is tasted by another?

The Veda says that one should not eat such tasted food (Yaducchistham). But Rama ate the fruits, which were tasted by Shabari. Animals and birds already taste the water and the fruits that we eat. Animals and birds are selfless and so such food is pure. Shabari also was selfless. All human beings are selfish. Similarly money, which is enjoyed by someone else, is also prohibited like food [one should not enjoy someone else’s money]. In the Vedic practice called ‘Vaishwadeva’ the person should not eat the food of some other person. But today the people who follow that practice take foodgrains from another person and cook those grains themselves and eat [thinking that Vaishwadeva means that ‘food cooked by another should not be eaten’]. This is a misinterpretation of Vaishwadeva. Actually, according to it you should not touch the wealth of anyone in this world [food is also a form of wealth]. Their sins will be transferred to you along with their money. The remains of the food eaten by the Lord are the purest form of food.
