What Hypertension Is
Hypertension means blood pressure is consistently higher than recommended. Over time, high blood pressure can increase the risk of heart disease, stroke, kidney disease, and other complications.
Blood pressure is influenced by genetics, age, body size, medications, sleep, physical activity, alcohol, sodium intake, and other factors. Nutrition is important, but it does not replace prescribed treatment.
What Research Tells Us About Nutrition
The DASH eating pattern is one of the best-studied dietary approaches for lowering blood pressure. It emphasizes vegetables, fruit, whole grains, low-fat dairy or suitable alternatives, fish, poultry, beans, nuts, seeds, and vegetable oils.
Reducing sodium can lower blood pressure, and the effect is often greater when a lower-sodium intake is combined with a DASH-style pattern. Potassium-rich foods can be helpful for many people, but intentionally increasing potassium is not appropriate for everyone.
Foods and Nutrients Discussed in the Evidence
A DASH-style pattern emphasizes minimally processed foods, lower sodium, and nutrient-rich plant foods.
Vegetables and fruit
Produce contributes potassium, magnesium, fiber, and other nutrients.
Whole grains
Whole grains add fiber and can replace refined grains.
Beans, peas, and nuts
These foods contribute plant protein, magnesium, potassium, and fiber.
Unsaturated fats
Vegetable oils, nuts, seeds, avocado, and fish fit DASH-style patterns.
Lower-sodium choices
Fresh or minimally processed foods often make sodium easier to manage.
Everyday Meal Ideas

When Individualized Help Matters
If you have chronic kidney disease, have been told to limit potassium, or take medications that can raise potassium, do not intentionally increase high-potassium foods without guidance.
Pregnancy-related hypertension, very high readings, or symptoms such as chest pain, shortness of breath, confusion, or neurologic symptoms require prompt medical care.
