# Nutrition with HIV and AIDS
Gut health and inflammation
In people with HIV, especially when immune status is still weak, gut tissue can become damaged. This leads to poorer absorption of nutrients and can cause chronic inflammatory reactions. When antiretroviral therapy (ART) works well, the gut barrier usually gradually recovers, but this can take months to years.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Research shows that certain food choices can help restore gut health. Foods that support the gut microbiome (the bacteria in your gut) — such as foods high in fiber, fermented products, and certain types of vegetables — are being studied for their role in reducing chronic inflammation in people undergoing treatment.

Prebiotics (substances that form a growth medium for healthy gut bacteria, such as inulin in onions and garlic) and probiotics (live bacterial cultures) are being studied as a supplement to treatment. The goal is to restore gut flora and thus combat inflammation, but research is still ongoing.
Nutritional intake and absorption
When gut function is disrupted, the body absorbs fewer nutrients. This can result in deficiencies of vitamins, minerals, and proteins, which can cause fatigue and muscle loss. A severely weakened immune system (especially with AIDS-related infections) can also reduce appetite and ability to eat.

Adequate intake of proteins, energy, and micronutrients (vitamin A, D, B12, folate, zinc, selenium) is important for everyone, but especially for people with HIV. The need may be higher than for people without HIV.
It is important to regularly check your nutritional status with your doctor or dietitian, especially if you have symptoms such as weight loss, diarrhea, or decreased appetite.
Drug interactions
Some antiretroviral medications work better on a full stomach, others on an empty stomach. Also, certain foods can change how your medications work. This requires individual attention.

Certain foods and supplements (for example grapefruit, St. John's Wort) can change the concentration of antiretroviral drugs in your blood. This can affect their effectiveness.
Discussing with your doctor or pharmacist which eating habits are important in your situation is essential. This is especially true if you take additional supplements.
Weight change and muscle function
Both unintended weight loss (cachexia) and unintended weight gain occur in people with HIV. This is related to the degree of inflammation, medication use, overall health, and lifestyle. With long-term antiretroviral therapy, weight gain and changes in fat distribution are not uncommon.
ResearchediPositive results in clinical studies, not yet standard treatment
Studies examine how food choices relate to muscle mass, bone density, and cardiometabolic health (heart and glucose metabolism) in people with HIV. Especially in older people with HIV, muscle weakness (frailty) plays a role.
Regular physical activity and adequate protein intake are mentioned in research as supportive, but must always be coordinated with your own situation and healthcare provider.
Insulin resistance and metabolic changes
Some antiretroviral drugs can contribute to insulin resistance and changes in glucose metabolism and fat metabolism. This increases the risk of diabetes and cardiovascular disease in the long term.
ResearchediPositive results in clinical studies, not yet standard treatment
Recent research focuses on the role of certain nutrients (such as betaine) in relation to insulin resistance and cognitive health in people with HIV. This is still an experimental research area; conclusions are not yet definitive.
How you eat can influence your glucose tolerance and metabolic health, but this requires discussion with your doctor and dietitian, not self-experimentation.
Nutrition for cognitive health
Severe HIV infection and certain antiretroviral medications can affect memory, concentration, and other brain functions. Nutrition plays a supportive role in brain function.
ResearchediPositive results in clinical studies, not yet standard treatment
Studies examine how nutrition (especially foods rich in antioxidants and omega-3 fatty acids) may contribute to cognitive health in people with HIV, but research is ongoing.
This is not a reason for self-treatment with supplements or special diets, but it is something to discuss with your care team.
Oral hygiene and eating possibilities
With reduced immune function, mouth and throat infections can develop (such as thrush) which can make eating painful. Medication use can also cause dry mouth.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Good oral hygiene and regular dental check-ups are important to prevent infections that make eating difficult.
If you have difficulty eating due to pain or dry mouth, your dental hygienist or dietitian can help you with adjustments (softer food, more fluids, etc.).
Alcohol and other substances
Alcohol can affect medication use and liver function and intensify inflammatory reactions.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Moderate to no alcohol use is recommended for everyone with HIV, especially if you have hepatitis B or C.
Advised againstiProven ineffective or harmful, or dangerous in combination with your treatment
Heavy drinking habits can further weaken your immune system and disrupt medication function.
Nutrition in poorer settings
In many countries with high HIV prevalence, nutrition and nutritional support are much more difficult to access. This has direct consequences for treatment outcomes.
This tab focuses on medical and biological aspects of nutrition. Social, economic and cultural factors around nutrition are equally important and fall outside this framework.
Personal nutrition choices
Because nutritional needs, medication use, gastrointestinal problems and metabolic health are different for everyone, general nutrition advice is not always useful.
**A registered dietitian** with experience in HIV can help adapt nutrition choices to your specific situation and prevent medication interactions. This conversation belongs in your regular care.
