Chemotherapy drugs damage the body, particularly the bone marrow which is where red blood cells are produced. Tree tomato also referred to as blood fruit is a rich source of iron which helps the body produce sufficient red blood cells. Other blood boosters include foods rich in calcium, iron, folate and vitamin B12 – foods like red meat, organ meat like kidney and liver, dark leafy green vegetables like spinach and kale, dried fruits like prunes and raisins, beans, legumes and egg yolks. Here are some foods to eat to boost blood levels.

Foods to avoid when undergoing chemotherapy


Your liver helps metabolize all the potential toxins in your bloodstream, a function that is exceedingly important while undergoing chemotherapy. For this reason, it’s best to be kind to your liver during this time.


Dieticians suggest people undergoing chemotherapy avoid taking dietary supplements including vitamins, minerals, herbals, and botanicals. The reason for this is there are potential drug-nutrient interactions that can interfere with the effectiveness of chemo treatment. Consult your doctor before taking supplements.

Sugar and bad fats

Avoid common sugar as well as glucose and high fructose syrup found in ice cream, fruit juice, cakes, chocolates, biscuits, puddings, and soft drinks. Avoid cow’s dairy, coconut oil, fried foods, processed meats and other processed foods.

Soy products

When it comes to soy products, consult your doctor about whether you can take them given your specific type of cancer.

A good rule of thumb is to eat foods that are hydrating, are lean protein, vegetables and nausea-reducing foods while undergoing chemotherapy.

***It is important to consult your doctor on what you should or should not eat as doctors may recommend that some foods not be eaten while somebody is undergoing specific cancer treatments.
