There is a popular saying nowadays: avoid the "Three Whites" (refined white rice, white flour, and white sugar). The Chinese character for dregs, "粕" (pò), is a combination of "白" (bái), meaning white, and "米" (mǐ), meaning rice. It seems our ancestors were telling us: refined white rice is the dregs, and the true essence is actually in the rice bran. A survey conducted by Harvard Medical School on 38,000 women showed that consuming foods high in sugar can cause a rapid spike in blood sugar, thereby increasing the risk of colorectal cancer. And these problem foods are mainly white bread, refined rice, and sugary pastries.
Dietary moderation and consistency are more important
As living standards improve, people are increasingly fond of refined diets, but the processing often leads to a loss of fiber, resulting in insufficient intake. Although the human body cannot digest and absorb fiber, it shortens the time food waste stays in the intestines, promotes the timely excretion of waste and carcinogens, and reduces the probability of colon cancer. Studies have shown that the time it takes for food to pass through the large intestine is closely related to the incidence rate of colorectal cancer. When a diet is primarily meat-based versus high in fiber, the time it takes to pass through the entire digestive tract is about 4 to 5 times longer for the former. This leads to prolonged stagnation of waste in the intestines,加重了肠道负担 (increases the burden on the intestines), and makes it more likely to induce cancer.
For cancer patients, it is even more crucial to master the right "degree" in their diet. Clinically, we observe that during the treatment period, patients and their families generally pay great attention to their diet, with 80-90% being able to control their cravings. After 3-5 years, when they enter the recovery phase, many people let their guard down, or out of ignorance, only seek to satisfy their gluttonous desires, leaving behind many painful lessons.
