Managing Treatment Side-effects with Diet

Chemotherapy can result in side effects that hinder the individual’s dietary intake and may affect treatment outcomes. These side effects can be managed by making modifications to the diet.

• Loss of appetite can be managed by eating small, frequent meals. Nutritious snacks should be made a part of the meals. Therefore, instead of three large meals, five or six small meals help improve appetite. Eating every few hours without waiting for hunger to set in helps reset appetite. Beverages such as tea and coffee should not be consumed with meals.
• Nausea is a very common side effect reported by cancer patients undergoing treatment. Foods that help with nausea during chemo include ginger, peppermint, lemon, and citrus fruits. Ginger ale, lemon juice, lemon tea, iced tea, sparkling water, and fruit juices help prevent nausea.
• Diarrhea can lead to loss of water and sodium from the body. Replenishing the body with adequate fluid intake like water, soups, fruit juices, and energy drinks is essential. Foods high in soluble fiber such as oats, lentils, chia seeds, and more can be consumed as well.
• Constipation may be experienced by some individuals. Including a diet rich in fiber that includes vegetables, fruits, whole grains, beans, and nuts helps treat constipation. Adequate water intake is pivotal along with consuming fiber.
• Loss of taste can make it difficult to eat foods. When foods taste metallic, using utensils made of plastic or wood can be helpful. Trying foods with strong flavors like lime, sucking on flavored candies, experimenting with new spices, and using fresh ingredients help tackle loss of taste.
• Mouth sores can be treated by using mouth rinses and eating foods at room temperature. Foods that are very hot, spicy, acidic, and dry are best to be avoided. Moist, bland foods such as oatmeal, custards, and puddings can be consumed(7^✔ ✔Trusted Source
