Looking at the question from the perspective of a pharmacist, health foods should refer to food products with supplemental tonic attributes. Those who have an insufficient nutritional supply after absorbing an ordinary intake of food can replenish themselves with these edibles.
站在藥劑師的觀點，健康食品應該是指食品輔助品，如果一般食物的攝取外，還有營養不足的情況，可以用這些食物補充。
