為滿足基因而吃飯

According to Heber, the varied colors in fruits and vegetables indicate "specific beneficial substances that help to prevent the common diseases that affect many of us as we get older." Damage to DNA leads to changes in our genes as we age that can result in diseases such as heart disease, cancer, and Alzheimer's disease. Substances found in plant foods protect our DNA.
該書的核心概念是要為滿足基因而吃飯。基因是遺傳，表面上看不可改變，但飲食結構與其存在互動關係，如果你有某種不良基因，營養補充不對時，不好的基因就會發展成疾病。 很多病症的出現與人的免疫系統有關，免疫功能增強了，防病、抗病能力也隨之增強，生病的機率也會大大減少。當你學習如何給你的膳食添加一系列顏色時，你就是在保護你的DNA了，它可以預防威脅健康和長壽的常見疾病。
