吃糖会加速肿瘤生长？假的！

Core Viewpoint - The belief that sugar accelerates tumor growth is prevalent among cancer patients, but there is no scientific evidence supporting this claim. Instead, a balanced diet is crucial for cancer patients to maintain their strength during treatment [2][3]. Group 1: Sugar and Cancer - Sugar intake does provide energy to cancer cells, which metabolize glucose more rapidly than normal cells. However, all cells in the body require glucose, and carbohydrates from food are converted into glucose regardless of sugar consumption [2]. - There is no scientific evidence that directly links sugar consumption to tumor growth. Overly restricting sugar may lead to malnutrition and decreased resistance, which can negatively impact the patient's ability to endure cancer treatments [2]. Group 2: Nutritional Recommendations for Cancer Patients - Cancer patients should focus on "eating well" and "eating enough." "Eating well" means consuming a variety of foods, including proteins, vegetables, fruits, and carbohydrates, to ensure balanced nutrition [3]. - It is recommended that cancer patients prioritize high-quality proteins (such as fish, eggs, and legumes), vitamins, and minerals, while opting for whole grains and starchy foods over refined carbohydrates to stabilize blood sugar and provide dietary fiber [3]. - "Eating enough" refers to ensuring sufficient caloric intake to maintain energy levels, which is essential for better tolerance of treatment side effects and improved treatment outcomes [3].
