What foods should I avoid with HIV?

Last reviewed: September 21, 2026

There is no single special diet required for everyone with HIV. Eat a varied diet suited to your health needs, follow food-safety guidance, and check your medication’s food and supplement instructions. Raw or undercooked animal foods and unpasteurized products can pose infection risks, especially with a weakened immune system. Calcium, iron and antacids can interact with some HIV medicines, and the timing rules differ by product.^[1][2][4][5]

First, the myth: there is no special HIV diet

NIH's fact sheet is unambiguous: "The basics of a healthy diet are the same for everyone, regardless of HIV status." The advice that follows is ordinary — variety across protein, dairy, healthy fats, vegetables, fruits and whole grains; enough calories to maintain a healthy weight; less saturated fat, sodium and added sugar; and prioritizing whole foods^[1]. HIV.gov points to the same national standard, citing the Dietary Guidelines for Americans, 2025–2030 and advising choices that are "less processed; are full of nutrients; and are limited in added sugars, saturated fat, and sodium"^[2].

Nutrition still matters for how you feel. NIH notes a healthy diet "can help the body process HIV medicines effectively, support immune health, and improve overall well-being," and that side effects such as appetite loss, nausea or diarrhea can make staying on a regimen harder^[1]. Before making big dietary changes — including starting supplements — HIV.gov advises talking with your HIV care provider or a registered dietitian^[2].

Food safety: the short, practical list

HIV.gov gives the reason in one line: "Because HIV affects the immune system, foodborne illnesses are likely to be more serious and last longer in people living with HIV than in people with a healthy immune system"^[2]. Its list is short: do not eat raw eggs, meats, or seafood — including sushi, oysters and other shellfish, and raw cookie dough — and do not drink or eat unpasteurized milk, other dairy products, or fruit juices^[2]. NIH's fact sheet names the same three categories: raw eggs or foods containing them; raw or undercooked poultry, meat and seafood; and unpasteurized milk, dairy, and juices^[1].

For people at increased risk of Listeria illness, CDC also advises avoiding unheated deli meats and hot dogs, raw sprouts, refrigerated smoked fish unless cooked in a dish, and unheated queso fresco-type cheeses even when made with pasteurized milk. Safer choices include pasteurized hard cheeses, sprouts cooked until steaming, and deli meats reheated to 165°F or steaming hot. Follow clean, separate, cook and chill practices, including safe water and prompt refrigeration.^[3][2]

If your CD4 count is low, the caution level goes up

People with advanced HIV or low CD4 counts need particular attention to food safety. NIH advises avoiding raw or undercooked meat and shellfish, especially when CD4 is below 200 cells/mm³, to reduce toxoplasmosis risk. Its HIV-specific guidance lists an internal temperature of 165°F–170°F for lamb, beef, venison and pork. Use a food thermometer: color or the absence of pink cannot reliably establish safety. Wash produce and wash hands after handling raw meat or soil.^[12][4]

Cat owners get reassurance rather than fear. The guidelines state that people with HIV "do not need to be advised to part with their cats" — though people with CD4 counts under 200 who are Toxoplasma-seronegative should have someone else change the litter daily, or wear gloves and wash their hands afterward^[4]. For most people with a suppressed viral load and a healthy CD4 count, everyday healthy eating applies, with basic food hygiene as sensible baseline care^[1].

Supplements and antacids: the interactions that actually matter

Some interactions can be managed with timing or food; others require avoiding a combination. NIH’s integrase-inhibitor table gives the following examples. AUC means total drug exposure measured in a pharmacokinetic study; these percentage changes are not treatment-failure rates.

• Dolutegravir (DTG) plus aluminum/magnesium-containing antacids: exposure fell 74% with simultaneous dosing and 26% when DTG was taken two hours before the antacid in the studies summarized by NIH. Take DTG at least two hours before or six hours after antacids containing polyvalent cations.^[5]
• Dolutegravir + calcium or iron: AUC drops 39% with calcium and 54% with iron when taken simultaneously while fasting. Take DTG with the supplement together with food, or separate by 2 hours before / 6 hours after^[5].
• Bictegravir (BIC) plus calcium or iron: exposure fell 33% with calcium carbonate and 63% with iron when taken together while fasting. BIC can be taken with calcium or iron together with food. Do not take BIC simultaneously with, or two hours after, these supplements while fasting. Aluminum/magnesium antacids have a different rule: take BIC at least two hours before or six hours after them.^[5]
• Oral cabotegravir + polyvalent cation antacids: levels are reduced; take the antacid at least 2 hours before or 4 hours after^[5].

The guidelines also warn that many multivitamins contain polyvalent cations and that "the extent and significance of chelation is unknown"^[5] — so mention every vitamin and antacid you take, including the ones that feel too ordinary to bring up. Separately, NIH notes that acid-reducing agents such as proton pump inhibitors, H2 blockers, and antacids can reduce absorption of antiretrovirals that need gastric acidity, specifically atazanavir and rilpivirine^[6].

Grapefruit, and "with food or without?"

Grapefruit can alter drug levels by affecting intestinal enzymes or transporters. The effect depends on the medicine, person and amount consumed. FDA advises checking the medication guide and asking a pharmacist about the exact drug; a warning may also apply to Seville oranges, pomelos or tangelos. Review all medicines, including those for conditions other than HIV, rather than using a blanket rule for every antiretroviral.^[7]

Follow the instructions for the actual product, not a general list of drug ingredients. Biktarvy and Dovato may be taken with or without food, with separate precautions for minerals and antacids. Odefsey requires a meal; Symtuza requires food. Dolutegravir does not universally require a meal, and a high-fat meal is not a universal requirement for rilpivirine. Formulation and coformulated drugs can change the instructions.^{[8][9][10][11]}
