客曰∶万病皆从口入，如何食反能治病耶？盖草木药石，得五行之偏气，如人之得疾。因五脏有偏胜，
则气血有偏倾。故用偏气之药物，治五脏偏胜之气血，使得归其正。然中病则已，不可过焉，过则药又反
能生病也。是故饮食，人赖以养者，贪嗜之，所以有万病皆从口入之说，亦犹是耳，且五谷得五行之正气
，尚有是说。盖饮养阳气，食养阴
气，《内经》言之详矣。五谷为养，五果为助，血气调和，长有天命。何况今人忽而不讲，惟知药可治
病，不知饮食起居之间，能自省察，得以却疾延年也，古人食治之方，良有深意，卫生者鉴之。

Guest asked: "All diseases enter through the mouth," so how can food and drink instead cure diseases? Generally, herbal medicines and minerals possess biased Qi of the Five Elements, similar to how humans contract illnesses. Because the Zang-Fu organs have excesses or deficiencies, the Qi and Blood also become imbalanced. Therefore, drugs with biased properties are used to treat the Qi and Blood imbalances caused by the excesses/deficiencies of the Zang-Fu organs, restoring them to normality. However, once the disease is cured, one should stop; overuse will cause the medicine itself to induce illness. Thus, diet is what sustains human life. If one indulges in gluttony and cravings, it leads to the saying that "all diseases enter through the mouth." This is the same principle. Moreover, grains obtain the upright Qi of the Five Elements, yet even they have such considerations. Drinks nourish Yang Qi, and foods nourish Yin Qi, as elaborated in the *Huangdi Neijing* (Yellow Emperor's Inner Canon). Grains serve as the primary nourishment, fruits assist, harmonizing Qi and Blood to ensure longevity. Why do modern people neglect this and fail to study it? They only know that medicine can cure diseases, not realizing that within daily diet and lifestyle, self-reflection and moderation can eliminate illness and prolong life. The ancient prescriptions for dietary therapy indeed hold profound significance; those who value health preservation should take note.
