Why Nutrition Matters During Cancer

Cancer treatment can sometimes affect your body's usual nutritional intake. Common side effects such as changes in taste, nausea and soreness of the mouth can make it more difficult to eat well.  

Over time, this may have an impact on muscle strength, physical function and how well the body copes with treatment.

What Can Help When Food Intake Isn't Enough?

When diet isn't meeting your needs due to low appetite, side effects, or increased requirements, oral nutritional supplements (ONS) can provide additional energy, protein, and key nutrients.

These nutritional drinks or desserts can support your intake at different stages of care, such as before, during or after treatment, helping to provide extra energy and protein alongside your normal meals.

Mary's Story: Staying Nourished Through Cancer Treatment

Mary, 56, was living with pancreatic cancer and finding it hard to eat well due to pain and significant weight loss. 

Working closely with her care team, her nutrition plan was carefully adapted at each stage, through surgery and chemotherapy, helping her maintain adequate nutrition and stay as strong as possible throughout her treatment journey.

Taking Action: Your Next Steps

Tell your doctor or dietitian about any changes in appetite, weight or digestive symptoms that make it harder to eat. If your food intake isn’t enough, oral nutritional supplements (ONS) can provide additional energy, protein and key nutrients.

Nutritional support may be considered before, during or after surgery or cancer treatment, based on advice from your healthcare professional, to help support your nutritional status.
