In this article, a contemporary rabbi mines classic rabbinic sources and later ethical writings to argue that Judaism offers insights into healthy eating and healthy living. Reprinted with permission from A Book of Life (Schocken Books).
Judaism postulates that we can approach food and eating in a spiritual way.
A midrash compares the creation of human beings to the striking of coins. As coins are struck, each is produced in the same image. When God creates people, each is created in God’s image, yet each one is unique.
This midrash is a basic affirmation of every body. No body can be more Godlike than any other. One could even say that this body is the one that has been given to me by God. In a sense, this is similar to saying that some people are overweight because of a genetic disposition, not because they cannot control their eating. For superficial reasons, plastic surgery can make some difference. When it comes to how tall or short you are, however, these things cannot be significantly changed at all. Thinking of your body as a gift from God is good beginning, though clearly for those born with disabilities there are difficult burdens that accompany that gift.
Still, this gift, this body, is give into our care and–like Hillel, who considered it a mitzvah (precept) to bathe in the bathhouse–we are responsible for striving for a healthy body because our body is the image of God. According to some rabbinic authorities, an understanding of the verse v’nishmartem m’od l’nafshoteikhem–“for your own sake, therefore, be most careful” (Deuteronomy 4:15)–is broader than avoiding harmful situations. It also implies not doing things that are clearly detrimental to our health. For these authorities, alcoholism, cigarette smoking, and overeating fall into this category.
“‘He who does good to his own self is a person of mercy’ (Proverbs 11:17)–as may be inferred from what Hillel the Elder once said. After bidding farewell to his disciples, he kept walking along with them. His disciples asked him, ‘Master, where are you going?’ he replied, ‘To do a good turn to a guest in my house.’ They said, ‘Every day you seem to have a guest.’ He replied, ‘Is not my poor soul a guest in my body, here today and tomorrow here no longer?'” (Leviticus Rabba 34:4).
