Hypertension: Foods to Eat & Avoid
High blood pressure is eased by reducing sodium and increasing potassium-rich foods.
Key principles
- Cut added salt/sodium
- Increase potassium
- Limit processed foods
Foods to eat
- Potassium — Promotes the excretion of excess sodium in urine and mitigates tension in the walls of the blood vessels, resulting in lowered blood pressure. Incorporate potassium-rich natural foods like leafy greens, bananas, and lentils to help manage hypertension, while minimizing processed foods high in sodium. [ICMR-NIN, WHO, PubMed]
- Amla — Rich in Vitamin C and antioxidants that strengthen blood vessels, reduce oxidative stress, and improve endothelial health. Include fresh or dried amla in your daily routine to support arterial elasticity. [ICMR-NIN, PubMed]
- Oats — Contains beta-glucan soluble fiber, which has been clinically shown to reduce systolic and diastolic blood pressure. Choose whole oats as a regular breakfast option to support heart health. [ICMR-NIN, USDA, PubMed]
- Curd — Bioactive peptides generated during dairy fermentation, alongside potassium and calcium, support blood vessel elasticity and blood pressure regulation. Incorporate low-fat, unsweetened curd as part of a low-sodium, mineral-rich diet to support cardiovascular health. [ICMR-NIN, PubMed]
- Garlic — Allicin and its derivatives stimulate the production of nitric oxide, which promotes vasodilation and helps lower systemic vascular resistance. Incorporate crushed or chopped garlic into daily cooking as a flavorful ingredient that supports a heart-healthy, low-sodium diet. [PubMed, WHO]
- Banana — The high potassium-to-sodium ratio helps the body excrete excess sodium and reduces tension in blood vessel walls, aiding in blood pressure regulation. Enjoy bananas as a convenient, naturally low-sodium snack to support daily potassium intake goals. [ICMR-NIN, USDA, WHO]
- Cabbage — Naturally low in sodium and high in potassium, aiding in blood vessel relaxation and blood pressure regulation. Include cabbage in your daily diet as a low-sodium vegetable to support overall blood pressure management goals. [ICMR-NIN, WHO]
- Potassium Chloride — Replacing sodium chloride with potassium chloride reduces sodium-induced fluid retention and promotes blood vessel relaxation, directly helping to lower elevated blood pressure. Use as a partial or full table salt substitute to help manage blood pressure, ideally as part of a balanced diet. [ICMR-NIN, WHO, PubMed]
- Spinach — Dietary inorganic nitrates in spinach convert into nitric oxide in the body, promoting vasodilation. Its high potassium content also helps balance excess sodium in the bloodstream. Consume spinach as part of a balanced, low-sodium diet to naturally support healthy vascular function and blood pressure management. [ICMR-NIN, USDA, WHO, PubMed]
- Pomegranate — Antioxidants in pomegranates act as natural ACE inhibitors, helping to relax blood vessels, complemented by dietary potassium. Consuming fresh pomegranate arils or moderate amounts of 100% pure unsweetened juice can support healthy blood pressure levels. [USDA, PubMed]
- Olive Oil — Polyphenols stimulate the production of nitric oxide, promoting vasodilation and reducing systolic and diastolic blood pressure. Include extra virgin olive oil regularly in salads or light cooking as part of a low-sodium, heart-healthy dietary regimen. [PubMed]
- Beetroot — Dietary inorganic nitrates in beetroot convert to nitric oxide, which dilates blood vessels, reduces vascular resistance, and helps lower blood pressure. Incorporate beetroot into a balanced diet to support blood pressure management, but avoid relying solely on it as a treatment. [PubMed]
- Broccoli — Naturally low in sodium and contains potassium, which helps regulate blood pressure by easing tension in blood vessel walls. Include fresh broccoli in a low-sodium diet to naturally support blood pressure management. [USDA, WHO]
- Hibiscus — Compounds in hibiscus act similarly to mild natural ACE inhibitors and promote nitric oxide production, aiding vasodilation and blood pressure reduction. Incorporate a cup of unsweetened hibiscus tea into your daily routine to support vascular health, but monitor your levels closely if you take blood pressure medications. [PubMed]
- Flaxseed — The synergistic effect of ALA, lignans, and fiber contributes to improved endothelial function, blood vessel elasticity, and reduced systemic inflammation, helping lower blood pressure. Can be safely used as a supportive dietary component alongside standard antihypertensive strategies. [PubMed]
- Skimmed Milk — Rich in potassium, calcium, and magnesium, which are key dietary minerals that collectively promote vasodilation and help manage blood pressure. Consume regularly as part of a low-sodium, nutrient-rich diet to support healthy blood pressure levels. [ICMR-NIN, ICMR-NIN, WHO]
- Fish Oil — Promotes endothelial nitric oxide synthesis, enhancing vasodilation and arterial elasticity to assist in blood pressure management. [PubMed]

People managing hypertension should track sodium from all sources, including MSG-containing seasonings and processed foods, to stay within safe daily sodium targets. [WHO, PubMed]
- Sodium Nitrate — Provides a direct source of dietary sodium, which promotes water retention and increases systemic vascular resistance. People with hypertension should avoid foods containing sodium nitrate to help manage and lower blood pressure levels. [WHO]
- Anchovies — While fresh anchovies support vascular health, salted dried anchovies are loaded with sodium, which promotes fluid retention and raises blood pressure. Choose fresh anchovies over dried, salted varieties. If using dried anchovies, soak and rinse them thoroughly to reduce sodium content. [ICMR-NIN, WHO]
