# Nutrition and dietary patterns in myelodysplastic syndrome
Nutrition plays a supportive role in myelodysplastic syndrome (MDS). The disease itself and its treatments can affect appetite, digestion and nutrient intake. Therefore, attention to nutrition is part of careful management of this condition. Below is an overview of dietary patterns and substances relevant to MDS treatment.
Protein-rich nutrition
ResearchediPositive results in clinical studies, not yet standard treatment
Protein-rich nutrition supports the maintenance of muscle mass and the body's capacity for recovery. In MDS patients undergoing intensive chemotherapy, adequate protein intake becomes important, as these treatments place considerable demands on the body.
Research from 2025 on medical nutrition therapy in patients with acute myeloid leukaemia (a related disease) showed that targeted protein intake was associated with better body composition and better clinical outcomes during intensive treatment. The same logic applies to MDS patients, although treatments and disease courses may differ.
In MDS, however, nutrient intake can be complicated by nausea, changes in taste perception and fatigue — all consequences of the disease or treatment. It is not just about the amount of protein, but also how easy it is to take in and how well the body can process it.
Nutrition with vitamins and minerals (folic acid, B12, iron, copper)
ProveniIncluded in official guidelines, or approved by EMA or FDA
Certain deficiencies — particularly of folic acid, vitamin B12, iron and copper — can occur in MDS and may worsen symptoms.
**Folic acid and B12:**
A case report from 2024 showed that severe folic acid deficiency can resemble MDS or acute myeloid leukaemia. This underscores the importance of healthy folic acid and B12 levels. These vitamins are essential for blood cell formation. Green leafy vegetables, grains and certain meat and dairy products contain these substances.
**Copper:**
Copper deficiency can also cause blood system problems that resemble MDS. This can occur after certain procedures (for example gastric bypass) or through certain dietary supplements. Copper-rich foods include nuts, seeds, shellfish and crustaceans, and wholegrain bread.
**Iron:**
Many MDS patients require regular blood transfusions, which leads to iron accumulation in the body. This is actually a problem that needs to be managed. Conversely, some patients may have iron deficiency. This should be discussed with your healthcare provider.
Current literature (2025) emphasises that nutritional deficiencies are common in people with haematological diseases and may be missed if not actively screened for.
Nutrition with eating problems from treatment
ResearchediPositive results in clinical studies, not yet standard treatment
Some MDS medications — particularly so-called hypomethylating agents — cause gastrointestinal complaints and can change hunger and nausea. A pharmacological analysis from 2024 catalogued these side effects and their nutritional consequences.
In this case, meals may be better taken in small portions, several times a day. Food that is easy to digest and not too spicy is often better tolerated. This should be part of patient-specific guidance from a dietitian, especially if nausea or taste changes occur.
A study from 2025 also highlighted that mealtimes for older adults with MDS are more than just food — the social aspect and the opportunity to eat together with carers contributes to wellbeing.
Nutrition and fatigue

Fatigue is a frequent symptom in MDS. Research from 2025 among Chinese MDS patients looked at factors related to fatigue. Although nutrition is not the only answer, a balanced dietary pattern plays a role in maintaining energy.
Regular, well-spaced meals and adequate calories help maintain energy. For some patients, portable food or snacks may be necessary, especially since a full plate may be less appealing.
Nutrition with antioxidants
ExperimentaliOngoing in study setting, outcome still unknown
Metabolomics research (investigation of metabolic substances) from MDS in 2025 suggested that certain metabolic processes related to antioxidants may be disrupted. This raises questions about the role of antioxidant-rich foods (such as baobab berries, dark green vegetables, and certain nuts).
Although this field is under investigation, there is no clear proven benefit of a specific antioxidant-driven diet for MDS patients yet. This remains experimental for now and belongs in scientific research, not in daily dietary choices without guidance.
Probiotics
ExperimentaliOngoing in study setting, outcome still unknown
Because many MDS patients receive antibiotic or chemotherapy treatment, which damages the gut flora, research has examined whether probiotics can help. A review from 2025 mentioned probiotics and other nutritional probiotics as potential supportive therapies for transfusion-dependent diseases.
However, effectiveness has not yet been definitively demonstrated. This remains experimental for now and should only be considered under the guidance of a healthcare provider.
Certain supplements (such as Garcinia cambogia): caution
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
A case from 2025 documented that a popular dietary supplement based on Garcinia cambogia led to anemia and liver disorders. These types of supplements can interact with blood and liver disorders already present in MDS, and can cause drug interactions.
Self-selected supplements, even natural ones, pose a risk and should always be discussed with your doctor — certainly not used independently.

**Nutrition and myelodysplastic syndrome: tailored approach**
Dietary choices in MDS are not one-size-fits-all. They depend on the stage of the disease, the chosen treatment, the patient's specific symptoms, and any existing deficiencies or special circumstances.
Many treatment centers work with specialized dietitians who are well-informed about MDS and the effects of treatment. They can take into account gastrointestinal complaints, loss of appetite, fatigue, and the need to adjust certain substances while keeping food interactions with medicines in mind.
This makes nutrition something that cannot be done on your own following a step-by-step plan, but something that requires good discussion with your healthcare provider and possibly a dietitian.
