What are the cancer-fighting foods? And is there anything to note on a cancer patient's diet? Here are some insights from Chubb's team.

8 Best Cancer-fighting Foods2

4. Cranberry:

Eat plenty of calories and protein such as chicken, fish, pork, beef, mutton, egg, dairy, cheese, legumes, nut, or nut butter, as well as legume products during treatment, especially for those who had surgery or wound.

2. Do eat enough calories

To ensure ample nutrient intake, eat whenever you want! A diet of 6 - 8 small meals daily is suggested. Feel free to add more calorie loading, such as full-fat milk, fruit smoothies, ice cream or sweet soup, but avoid choosing food with high fat content, too spicy or too sweet.

3. Do keep hydrated

It is crucial to keep hydrated during treatment. Apart from water, soup and liquid food is also a viable option, especially when experiencing chapped lips during treatment. Fruits with high water content like watermelon are good choices. Avoid citrus fruits including oranges and kiwi fruit as it may provoke mucosa or wounds.

4. Do take dietary supplements as needed

During chemotherapy or radiotherapy, patient may experience dysphagia, where dietary supplements come handy.

5. Don't cook in high heat
