Hello, there is basically no scientific basis. Modern science shows that no food can satisfy all the nutrients the human body needs, so it must be matched with different foods. Obviously, the protein content of sweet potato meal is not enough, and cancer patients can eat sweet potato meal, but the nutrition is not enough, so it is not recommended to eat more. Cancer patients suggest a ketogenic diet, that is, eat more fat, with a certain amount of high-quality protein, and try to eat less starch food, because starch food can be directly converted into sugar in the body, which is easy to become.
