Good nutrition is essential during cancer treatment

cancerA good diet and the right nutrition are important whether you are in good health or not. However, it is even more vital when you are getting cancer treatment. The treatments can be really harsh on the body. For example you may feel weak, lose a lot of weight, or even find your body no longer tolerates certain foods. As a result you need to adapt your diet.

Bespoke diets

The most important thing to keep in mind is that cancer treatments can vary and people respond to them differently. Therefore, it is crucial to tailor the diet to the individual. Look at what the person needs and how the right foods can ensure they have energy, feel better, reduce the risk of infection, and improve their ability to deal with the side effects of treatment.

What should a diet for cancer treatment include?

As we said above the best thing is to ensure each person has a bespoke diet that works for them. However, there are a number of things that most people will likely need. This includes:


Every healthy diet needs proteins because they help with the growth and repair of body tissue. On top of that, they are vital for a healthy immune system. It may be a good idea to choose a diet with more protein if you are getting cancer treatment. This can help with healing.

Fats and oils

During your treatment it is important to ensure you are eating the right foods so you have energy. Healthy fats and oils are really good. You should be looking to get more monounsaturated and polyunsaturated fats. In some cases it may even be necessary to eat more foods that are high fat to account for not eating as much.


While you need fats and oils for energy, your main source will always be carbs. Again you may need to get more of them into your diet to account for how your body reacts to the treatment. Try to stick to healthy carbs though, including fruits, vegetables, and whole grains.

Vitamins and minerals

It is also important to ensure you get the right vitamins and minerals in your diet. If you are eating enough protein and healthy carbs you are on the right track. However, cancer treatment can make this harder to do. If so, it may be a good idea to choose supplements. The key here is to select the right ones. It is a good idea to talk to a GP or nutritionist to ensure that a supplement won’t affect your treatment. Some can also be harmful in very high doses.
