What we eat affects our health. Unfortunately, it is often only illness that makes us question whether our diet is appropriate. We talk to Aleksandra Kapała, a doctor from the Hospital Nutrition Team at the Oncology Centre - Institute in Warsaw, about how a well-chosen diet can affect our health and whether cancer can be prevented in this way. The 'I'm with you' programme addresses various topics concerning the health of women with cancer; a healthy diet is an important factor in prevention and treatment.
