There is a saying circulating in the community that "eating sugar can accelerate tumor growth". In outpatient clinics, many doctors often encounter cancer patients who are "afraid to eat": experiencing various side effects of treatment while eating a "rabbit meal", which is truly pitiful. But does eating sugar really 'feed' cancer cells and promote their growth? In fact, the sugar intake by the human body does provide energy for cancer cells. Because cancer cells are metabolically active, they consume glucose at a faster rate than normal cells. But all cells in the human body require glucose for energy supply, and regardless of whether sugar is ingested or not, the body will convert carbohydrates (such as rice, fruits, etc.) into glucose. At present, there is no scientific evidence to suggest that "eating sugar directly promotes tumor growth", and blindly banning sugar may lead to malnutrition and decreased resistance in patients, which is not conducive to their tolerance to various anti-tumor treatments. Properly limiting refined sugar intake, such as white sugar, candy, sugary drinks, etc., can reduce obesity, diabetes and cardiovascular and cerebrovascular diseases. But for cancer patients, there is often a significant decrease in food intake and weight loss due to the disease itself or treatment side effects. In this case, there is no need to deliberately "avoid food". On the contrary, cancer patients should 'eat well' and 'eat enough'. Eating well "refers to consuming a variety of different types of food (meat, vegetables, fruits, staple foods, etc.). Cancer patients consume more energy and are more prone to malnutrition, so it is important to ensure a balanced diet. It is recommended that patients optimize their dietary structure and prioritize supplementing high-quality protein (fish, eggs, beans), vitamins, and minerals; Choosing high-quality carbohydrates and replacing refined rice and flour with whole grains and potatoes can stabilize blood sugar levels and provide dietary fiber. Eating enough "refers to the patient's daily intake of sufficient energy from food, which keeps the body in a good state and better tolerates various adverse reactions caused by anti-tumor treatment, resulting in better treatment outcomes. In addition, patients can seek medical treatment at a regular hospital's nutrition department during the treatment period. Please have a doctor develop a personalized diet for you and follow the doctor's advice to supplement appropriate nutritional supplements as needed. (New Society)
