Food during treatment- what to avoid

My whole treatment was overseen by my loving husband who is a food nazi. I only ate organic, vegetarian mainly 95%, the main thing we focused on was keeping up the probiotic to keep the gut flora healthy. Chemo really knocks out your immune system, so any food that has a bacterial risk is possibly why they talk about eggs. I found all foods with preservatives (most are carcinogenic) all foods with sugar, as cancer feeds on sugar especially processed sugar. So fresh food is the best & added immune support through some foods.
A fabulous regime to follow is an author called Cindy O'Meara - "Change your habits - Change your life" Book & websites are fantastic.
