Patients with prostate cancer can eat beef. Beef is a high-protein food, and as cancer is a consumptive disease, it is generally advised to enhance nutrition in the diet, such as meats, proteins, vegetables, and fruits to maintain a balanced diet with both meat and vegetables. Avoid junk food, such as pickled vegetables from pickled jars, barbecue items, or excessively oily foods with high fat content. Those should be avoided as much as possible, but other foods, including beef, can be consumed.
