Quoted TextFor wild people around the world there were no seedless grapes. The eggplant didn’t exist. Corn was a grass with two rows of kernels concealed inside very hard fruit cases. And watermelon (its ancestor) was a small, seeded, extremely bitter fruit about the size of a lemon. The point is that these foods aren’t ancestral foods and represent an agricultural food — foods that have been genetically modified through breeding and subsequently possess altered nutrition.
Quoted TextUnderstand that your genome, the exact sequences of nucleotides, is almost identical to people living 50,000 years ago. But clearly something has changed, and that is the expression of genes.
The food you eat has a profound effect on genetic expression (the turning on and off of genes that code for proteins). In fact, as much as 30% of the expression of your genome is affected by the plants you eat (through tiny structures called micro RNAs).
If we add up the sum total of food’s effect on our genome, it is even more substantial. Therefore, it seems prudent to consume foods that have a long history of positively impacting the functioning of our genetic machinery.
Quoted TextWhen you purchase cultivated plants, seek out forms that more closely resemble their wild ancestors (e.g., blueberries, raspberries, blackberries, cranberries, seeded grapes, ground‐cherries, mulberries, mustard greens, whole grains from more ancient species, yucca root).
Avoid large, super‐sweet, seedless forms (forms that couldn’t even exist without our care because they have lost the ability to defend themselves from herbivores).
Follow the seasonality of foods more closely. If you live in a region that receives a lot of snow, your plant foods should be very different that time of year than what you consume during the growing season.
Learn to appreciate stronger flavors, including bitters and resins. These indicate the phytochemistry of the plant is intact and the medicine is still present (i.e., it has not been bred out).
