Its not always an easy task, as cancer medications can cause nausea while radiation treatment can make the mouth sore, affect the taste buds and lead to a loss of appetite. A nutritious diet can help patients maintain a healthy body weight and stamina levels, better tolerate the side-effects of treatment and also recover faster.
Avoid stringent food restrictions Since cancer treatments often cause side-effects like nausea and taste changes leading to a loss of appetite, it is important that patients dont have too many dietary restrictions imposed on them.
Foods to avoid
Deep fried, grilled, barbequed, baked meats since subjecting animal protein to high heat creates carcinogenic byproducts called heterocyclic amines
Excessive intake of salt, sugar, and oily foods
Red meat and processed meats such as bacon, ham, sausages
Preserved foods like pickles, jams, kiam chye (salted mustard green), and century eggs as they contain nitrites which are carcinogenic
Additionally, cancer patients should avoid excessive intake of vitamin supplements, as they act as antioxidants and can interfere with chemotherapy when taken in large doses.
