Carbohydrates are one of the main macronutrient categories along with protein and fat. Food sources include whole grains, beans, peas, nuts, seeds, vegetables, and fruits.
Scientists emphasize that many risk factors for breast cancer are controllable. An overall poor diet, one that is high in sugar and fat while also low in fiber and nutrients, is responsible for one-third of all breast cancers and a driver of triple-negative breast cancer. A high intake of refined carbohydrates is associated with increased breast cancer incidence.
According to a study published in the American Journal of Clinical Nutrition, a high fiber diet could lower breast cancer risk. Researchers found that for every ten grams of added fiber daily, which equals about half- to one cup of beans, breast cancer risk decreased by 7 percent. The findings are based on ten studies involving more than 710,000 people over seven to eighteen years. Other high-fiber foods include vegetables, whole grains, and lentils.
A diet rich in complex carbs and low in simple carbohydrates is linked to reduced cases of breast cancer. Carbohydrates in their unrefined form are considered complex as opposed to simple or refined. Complex carbs are rich in natural soluble and insoluble fiber.
High blood sugar, or hyperglycemia, is the result of intake of more sugar than our bodies can metabolize at one time. Sugar in the blood causes damage to cells and when uncontrolled can lead to nerve damage. A high intake of sugar suppresses the immune system and white blood cell production while feeding cancer growth. High blood sugar also provides food for unhealthy microbial growth, such as fungus (candida) and pathogenic bacteria. Sugar also poses a higher risk for pre-menopausal than for postmenopausal breast cancer.
The uptake of sugar in malignant cells can increase the development of cancer and has an epigenetic effect on nonmalignant human breast cells leading to increased growth. Therefore, avoiding dietary sugar and maintaining a high level of protein and fiber intake are primary strategic goals in cancer recovery.
Hyperglycemia is common in cancer patients but can be reversed through diet, nutrients, and simple lifestyle changes. Increase plant foods that are rich in fiber, protein, and water, while reducing simple carbohydrates (especially sugar) and also exercising and getting adequate sleep.
Hyperglycemia has been linked to causing vitamin C deficiency. Optimal levels of ascorbic acid (vitamin C) is important for immune function. Higher levels of blood glucose appear to decrease not only blood levels but also cellular stores of ascorbic acid.
