Potassium on a vegan diet

Potassium is the mineral the modern diet is short on, and plant-based eating is where it is easiest to get. Fruit, vegetables, beans and potatoes are all loaded with it.

What potassium does

Potassium works in every cell, and getting enough is part of why fruit-and-vegetable-rich diets help blood pressure.

Primary source 01 / 02

Potassium is present in all body tissues and is required for normal cell function because of its role in maintaining intracellular fluid volume and transmembrane electrochemical gradients

A plant-diet strength

Most people fall short of the recommended potassium intake, and the fix is the food a plant-based diet already centres on.

Many fruits and vegetables are excellent sources, as are some legumes (e.g., soybeans) and potatoes.

A vegan diet built on fruit, vegetables, beans and potatoes is naturally high in potassium, which is one of the quiet reasons plant-based eating tends to help blood pressure. This is a nutrient where the plant diet has the advantage rather than a gap to manage.

  • Magnesium on a vegan diet Magnesium is one of the easier minerals to get on a plant diet, because its best sources are exactly the foods a good vegan diet is built on.
  • Plant-based diets and blood pressure Plant-based eating lowers blood pressure by a few millimetres of mercury, small for one person but the kind of shift that moves population risk.
  • Calcium and bone health on a vegan diet This is the page where being on veganism's side means telling you the uncomfortable finding: vegans break more bones in the data, and calcium is the lever that moves it.

Frequently asked

Do vegans get enough potassium?

Usually easily. Fruits, vegetables, legumes and potatoes are all excellent sources of potassium, so plant-based diets tend to be rich in it. Most people, vegan or not, would benefit from eating more of these foods.

What are good vegan sources of potassium?

Many fruits and vegetables, plus legumes like soybeans and potatoes, according to the NIH. These are central to a whole-food plant diet.
