With 150,000 new cases each year, breast and prostate cancer are the most common types of tumors in Germany and Austria. Both types of cancer are closely linked to hormonal balance, which is why the same dietary measures can positively affect health. The book includes not only a list of harmful foods but also a list of particularly recommended foods, including certain spices, nuts, as well as fruits and vegetables. The management of sugar and carbohydrates is also addressed in a dedicated chapter, along with the consumption of animal protein. Proper nutrition can alleviate and combat the side effects of cancer treatment, such as nausea, digestive issues, and dry mouth. With the right foods, the immune system is additionally strengthened, providing the weakened body with the necessary energy.
