Prostate cancer is curable, but certain lifestyle changes can aid the treatment process. So, it helps to make better food choices when dealing with the disease. This is especially important if one is undergoing procedures such as chemotherapy or immunotherapy that use powerful chemical agents to destroy cancer cells. These prostate cancer treatments often lead to side effects like nausea, heartburn, and headache, which can worsen with the intake of the following foods:  Processed meat Processed meats such as hot dogs, sausages, beef jerky, pepperoni, and bacon contain high levels of sodium and saturated fats. Similarly, deli meats such as roast beef and turkey are also rich in sodium and unhealthy fats, which can lead to heartburn, indigestion, and elevated blood sugar. The high sodium and saturated fat content can disrupt the recovery process for those dealing with prostate cancer. One should opt for lean sources of protein like fatty fish, poultry, and plant-based alternatives (tofu or beans). Red meat Adding protein to meals is crucial when undergoing treatments for prostate cancer, as the nutrient can improve muscle strength and manage fatigue. While meat can be a rich source of protein, one should avoid excessive intake of red meat like pork, lamb, and beef.
