Halakhah sa Mga Kawikaan 25:27: Mishneh Torah, Human Dispositions

It is necessary for man to set his heart and all his efforts solely to know the Name, blessed is He! so that his sitting down, his rising up and his speech shall be facing this goal. How may he accomplish it? When he will buy, or sell, or do work for wages, he should not have in his heart the accumulation of money only but he should perform these duties as a means to acquire the necessities of the body, as food, drink, dwelling-place and marriage; likewise when he will eat, drink, or lead a family life, he should not set his heart upon these things for the sole enjoyment thereof, until, as a consequence he will not eat and drink save that which is sweet to the palate, and marry to gratify his sensuality only. But he shall set his heart to eat and drink solely in order to keep his body and limbs in good health. He, therefore, should not eat everything his palate craves for like a dog or an ass, but partake of the things which are wholesome to the body whether bitter or sweet; and he shall not eat food which is bad for the body even though it be sweet to the palate. For example? One whose body was feverish shall not eat meat, nor honey, and drink no wine, as the subject was proverbally expressed by Solomon: "To eat too much honey is not good" (Prov. 25.27); he should rather drink cichorium intybus, even though it is bitter, as a consequence whereof he will eat and drink solely as a remedial means so that he may become healthy and stay healthy, seeing that it is impossible for man to sustain life save by food and drink. Likewise in connubial relation there shall be no coition save when it is of benefit to health, or to sustain species. One should, therefore, not yield to every urge, save when knowing that emission of semen is a helpful means medically or to sustain species.
