Oncologists have been moving away from the notoriously unpopular neutropenic diet. It requires nearly all food to be cooked to high temperatures — or, as some have described it, “boiled to death” — to reduce the risk of food-borne illnesses. But since evidence in recent years suggested the diet didn’t actually help ward off infections, doctors started leaning away from a strict neutropenic diet.
Now, a new study published last week in the Journal of Clinical Oncology is giving some physicians pause about fresh fruits and vegetables for patients whose treatment involves heavy suppression of the immune system, particularly neutrophils, white blood cells that are key to preventing infection. Contrary to research in the past, the trial found that certain blood cancer patients who were allowed a less restrictive or liberalized diet had 11% more infections than patients who were prescribed the neutropenic diet.
