There is no special 'HIV diet.' NIH states the basics of a healthy diet are the same for everyone, regardless of HIV status. Two real cautions apply: food safety — skip raw eggs, raw or undercooked meat and seafood, and unpasteurized dairy and juice, because foodborne illness can hit harder — and timing calcium, iron, multivitamins, and antacids around your HIV medicine.
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].
CDC's guidance for people with weakened immune systems adds the Listeria list: any cheese made with unpasteurized milk, raw milk, yogurt or ice cream, raw or lightly cooked sprouts, unheated deli meat, cold cuts, hot dogs and dry sausages, and refrigerated smoked fish. The safer swaps are practical rather than restrictive — hard cheeses made with pasteurized milk, sprouts cooked until steaming hot, and deli meats reheated to 165°F[3]. Then the four basics HIV.gov cites: clean, separate, cook to temperature with a thermometer, and chill promptly — plus water safety, since water can carry parasites, bacteria and viruses[2].
If your CD4 count is low, the caution level goes up
Food-safety rules matter most for people with advanced HIV or a low CD4 count. NIH's opportunistic-infection guidelines advise that people with HIV, especially those with CD4 counts below 200 cells/mm³, should not eat raw or undercooked meat — including undercooked lamb, beef, pork, or venison — and should not eat raw shellfish, including oysters, clams, and mussels, to reduce toxoplasmosis risk[4]. The same guideline gives concrete numbers: lamb, beef, venison and pork should reach an internal temperature of 165°F to 170°F, which in practice means meat cooked until no longer pink inside[4]. It also advises washing hands after contact with raw meat, gardening or soil, and washing fruits and vegetables well before eating them raw[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
This is the most actionable part of the page, and it is about timing, not banning anything. NIH's integrase inhibitor interaction tables show that antacids and mineral supplements can meaningfully cut absorption of common HIV medicines:
- Dolutegravir (DTG) + antacids containing polyvalent cations: AUC drops 74% taken together, 26% taken 2 hours before. Guideline instruction: take DTG at least 2 hours before or at least 6 hours after such antacids[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) + calcium or iron: calcium carbonate antacid drops AUC 33% while fasting; iron drops it 63% while fasting. Take BIC and calcium or iron together with food; do not take on an empty stomach[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 is the classic question, and honest reporting beats a blanket ban. A peer-reviewed review explains the mechanism — grapefruit and Seville orange juice inhibit intestinal CYP enzymes, especially CYP3A4, and protease inhibitors have the highest interaction potential because they are extensively CYP-metabolized[7]. But the measured effects vary widely: saquinavir AUC and Cmax rose 50% and 93% with grapefruit juice, amprenavir Cmax fell 22% without a significant AUC change, and indinavir AUC and Cmax were essentially unchanged[7]. The review's own conclusion is that there is "insufficient evidence available to make recommendations about consuming juice or alcohol with antiretroviral drugs"[7]. Practical line: ask your pharmacist about your specific regimen, especially if it includes a protease inhibitor.
Food timing is more actionable. The same review lists medicines to take with or immediately after a meal — including tenofovir disoproxil, etravirine, rilpivirine, dolutegravir, elvitegravir, atazanavir, darunavir, lopinavir, ritonavir and saquinavir — and medicines to take on an empty stomach, including efavirenz and indinavir, with all others taken regardless of food[7]. For rilpivirine specifically, bioavailability improved with a high-fat meal, and pooled data showed higher AUC and Cmax in the fed state[7]. Your pharmacist can confirm exactly where your own regimen falls.
Related questions
Do I need a special HIV diet?
No. NIH states that the basics of a healthy diet are the same for everyone, regardless of HIV status, and HIV.gov points to the general Dietary Guidelines for Americans. The HIV-specific parts are food safety and timing certain supplements and antacids around your medicine.
Can I ever eat sushi again?
HIV.gov advises not eating raw eggs, meats, or seafood, including sushi and raw shellfish. NIH's opportunistic-infection guidelines flag raw shellfish especially for people with CD4 counts below 200. Discuss your own CD4 count and risk tolerance with your provider.
Can I take a calcium or iron supplement with my HIV pill?
Timing matters. NIH advises taking dolutegravir or bictegravir together with calcium or iron and food rather than on an empty stomach, or separating dolutegravir by at least 2 hours before or 6 hours after. Taken together while fasting, iron reduced dolutegravir exposure by 54% and bictegravir exposure by 63%.
Is grapefruit dangerous with HIV medicine?
It depends on the drug. Grapefruit inhibits CYP3A4 and matters most for protease inhibitors, but measured effects ranged from essentially none to large, and the review authors concluded the evidence is insufficient for blanket recommendations. Ask your pharmacist about your specific regimen.
