# Nutrition in Non-Hodgkin lymphoma
Malnutrition and treatment outcomes
Malnutrition is common in people with non-Hodgkin lymphoma, especially during and after treatment. Research shows that nutritional status at the time before intensive treatments (such as stem cell transplantation) is linked to how the disease progresses.
ResearchediPositive results in clinical studies, not yet standard treatment
People with better nutritional status before undergoing stem cell transplantation have better chances of long-term disease-free survival.
This is related to how well the body can cope with the condition and the treatment. When the body has sufficient reserves, it can recover better from intensive therapies.
Weight loss and muscle loss
Many patients lose weight, especially as a result of the cancer itself or side effects of treatment. This weight loss is not merely cosmetic: it is often accompanied by loss of muscle tissue, which affects strength and recovery prospects.
ProveniIncluded in official guidelines, or approved by EMA or FDA
When muscle loss occurs, this worsens overall health and can make the body less resilient. Preventing or limiting muscle loss is therefore one of the points of focus during treatment.
Weight loss can have various causes: reduced appetite due to illness or medication, pain when swallowing, nausea, or changes in taste. A dietitian can help adapt eating habits to what works well at that time.
Gastrointestinal problems and nutrition
Chemotherapy, radiation, and certain other treatments can affect the gastrointestinal tract. This sometimes leads to nausea, diarrhea, constipation, or pain in the mucous membranes. These side effects can make eating difficult and prevent nutrient absorption.
ResearchediPositive results in clinical studies, not yet standard treatment
Gastrointestinal problems during cancer therapy have a direct impact on how well the body can absorb and use nutrition. This can cause nutritional deficiencies that require extra attention.
Eating regularly in smaller amounts, drinking enough, and keeping food easy to chew and digest are common adjustments. Depending on the treatment, certain foods may be better tolerated than others.
Inflammatory markers and nutrition
Blood values that indicate inflammation are measured regularly in non-Hodgkin lymphoma.
ResearchediPositive results in clinical studies, not yet standard treatment
Research suggests that certain eating patterns and nutritional indicators are linked to these signs of inflammation and possibly to prognosis, but this has not yet been translated into clear recommendations for individual patients.
This area of research is growing, but currently there are no specific 'anti-inflammatory diets' that are routinely prescribed. The significance of inflammatory markers in relation to nutrition is not yet clear enough for personal advice.
Drug interactions
Certain foods can interact with medications used for non-Hodgkin lymphoma. This can include, for example:
- Foods that affect certain enzymes in the liver (for example grapefruit with some medications)
- Food that changes the absorption of medications
ProveniIncluded in official guidelines, or approved by EMA or FDA
These kinds of interactions are real and can be important. Which interactions are relevant for you depends on your specific treatment. This is something to discuss with your healthcare provider or dietitian, because food does not need to be avoided — the point is knowing how best to combine it with your medications.
Proteins and muscle support
Proteins are important for maintaining muscle mass and tissue repair. During and after treatment, protein needs are sometimes increased, especially if muscle loss occurs.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Adequate protein intake helps the body deal better with treatment and recovery. This can be through regular food (meat, fish, dairy, nuts, legumes) or through nutritional supplements, depending on what you can eat and tolerate.
The exact amount of protein needed varies from person to person and situation to situation. A dietitian can provide personal advice on this.
Nutritional supplements and vitamins
Many patients want to use supplements. However, there is insufficient evidence for most nutritional supplements and vitamins whether they really help with non-Hodgkin lymphoma itself.
UnproveniNo scientific evidence that it works
Although healthy eating and sufficient vitamins and minerals are important for general well-being, there is no evidence that extra supplementation beyond normal intake improves disease outcomes.
Some supplements can also interact with treatments or even be harmful. It is important to discuss this with your doctor or dietitian before adding anything.
Antioxidants and 'detox' food
Internet and other sources sometimes suggest that certain foods rich in antioxidants (such as certain berries, herbs or tea) can 'fight' cancer or 'detoxify' the body.
UnproveniNo scientific evidence that it works
Although antioxidants occur naturally in food and can be part of a healthy diet, there are no proven effects of specific 'detox' food on non-Hodgkin lymphoma. The idea of 'detoxifying' the body through food is not scientifically grounded.
Healthy, varied food is, however, always wise, both for general well-being and to support the body during difficult treatments.
Alcohol use
There is less clear research available on alcohol and non-Hodgkin lymphoma than on many other topics.
UnproveniNo scientific evidence that it works
It has not been demonstrated that moderate alcohol use worsens the disease, but neither that it is safe. This is something to discuss with your healthcare provider, especially since certain medications do not mix well with alcohol.
Nutrition after intensive treatment
After intensive treatments such as chemotherapy or stem cell transplantation, the body may need weeks to months to fully recover. Appetite and digestion do not always normalize immediately.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Nutritional support during the recovery phase is important, both to restore weight and muscle mass and for the body's general recovery. This may require continued attention for some time.
A dietitian can help with a recovery plan that aligns with how your body is recovering.
Practical adjustments
The following adjustments are commonly used, although this is not a fixed protocol:
- **Small, regular meals** instead of three large ones, when experiencing nausea or fatigue
- **Adequate hydration** to prevent dehydration, especially with diarrhea
- **Soft, easily digestible food** when the stomach is sensitive
- **Follow your food preference**: eat what appeals to you at that moment, even if it's 'unconventional'
- **Hygiene** when immune defenses are low due to treatment
These are not strict rules, but signals of what many patients find helpful. Your own instinct and what your body can handle are just as important.
Collaboration with a dietitian
The best place for personalized nutritional advice is a dietitian familiar with cancer treatment. They can take into account your specific disease stage, treatment, side effects and personal wishes.
