Cancer Diet During Chemotherapy

It is recommended that a Cancer patient eats light on the day of chemotherapy. Avoid eating fatty, or spicy foods during the days of chemotherapy.

Diet Before Chemotherapy

Chemo diet before the procedure can include light, bland food such as:

  • Yogurt
  • Fresh fruits 
  • Cottage cheese
  • Poached eggs and toast
  • Toasted bagel 
  • Cereal & milk (if lactose intolerant)
  • Chicken rice soup with saltine crackers

It is advised to bring a small, flat snack during the chemotherapy session. You can also try breakfast with low-acid juices such as apple, grape, and fruit honey, liquid yogurt, fruits, and crackers. Bring a water bottle filled with your favorite drink. Avoid acidic food that can irritate the digestive system. Dr. Sachin Marda, Sr. Consultant Oncologist & Robotic Surgeon (Cancer Specialist) at Yashoda Hospitals, Hyderabad says, “Fruits and vegetables are rich in cancer-fighting antioxidants. In fact, a diet high in fiber is linked with a lower incidence of colon cancer. Switch to organic produce to dodge harmful chemicals and pesticides.”

Post Chemotherapy Diet

Chemotherapy can have certain side effects. Below are some tips to cope with the side-effects of Chemotherapy. 

Keep food tasty: Chemotherapy can affect your taste buds especially some food and drinks can taste metallic or unpleasant. The two most common things that become unpleasant during chemotherapy are water and meat. If plain water is difficult to drink, try drinking flavored mineral water or lemon water. If some meats are difficult to eat, try other sources of proteins such as eggs, low-fat milk, beans and fish which helps in fighting Cancer with food.

Fight constipation: Some people get diarrhea with chemotherapy, while others suffer from constipation. Staying hydrated is important to avoid constipation. If you are not used to high amounts of fiber, ensure to increase your fiber in diet slowly. 

Control weight gain: Some Cancer patients are more likely to gain weight during treatment. It is suggested to consume low-fat meals, snacks, and lots of vegetables.

Improve appetite: Most people who have had chemotherapy will find themselves hungry. Since carbohydrates are generally well digested, it is recommended to drink hot cereal, peanut butter, or other nut butter, try snacks like pita bread with hummus. Other foods to consider include yogurt and mixed soups.

Reduce diarrhea: If you have diarrhea, avoid fatty & fried foods, caffeine, sugary drinks & fruit juices, salads, raw foods, and sugary spirits. Cancer foods that are well tolerated after chemotherapy are oats, fruits without the skin, sweet potatoes and squash. 

Easy to follow tips: Post chemotherapy 

  • Eat small meals and snacks throughout the day 
  • Eat low fat foods
  • Try cold foods as these give off less odor & aroma and are especially important if you feel nauseous. Hot foods can have more odor, therefore causing an aversion to certain foods.
  • Drink fluids frequently to prevent dehydration. It also helps remove some of the byproducts of chemotherapy. Try other sources of fluids such as, Apple and grape juice, Fruit nectars, Low-salt broth, Clear soups, Gelatin, Herbal teas, such as ginger and mint and weak black teas
  • Take your anti-nausea medication as prescribed by the healthcare professional.
