In this potassium-rich foods chart, you will find natural fruits and vegetables and plant-based foods that are good sources of this all-important mineral. They also have the advantage of being low in sodium, a benefit that protects against arterial hypertension instead of meat derivatives, preserves, and salt-preserved foods.
People with a healthy diet consisting of meals on the following potassium-rich food chart should naturally get plenty of this vital mineral. Failure to get adequate amounts of potassium can result in heart disease, stroke, cancer, digestive disorders, infertility, arthritis, and high blood pressure. Your physician may recommend supplements and an improved diet consisting of meals high in potassium.

Chemical composition of potassium: mineral element.
Sources of potassium: Potassium is widely distributed throughout all foods, both plant and animal-based, although plant-based foods predominate.
Potassium absorption: Potassium is absorbed quickly in the small intestine. Typically, 90% of potassium in foods is absorbed.
Potassium function: Potassium is the third most abundant mineral in the body after calcium and phosphorus and is the ion in the highest concentration within the cells. It is involved mainly in the following processes:
- Acid-base balance,
- Muscular relaxation,
- Secretion of insulin in the pancreas.
Deficiency symptoms: muscle weakness and cardiac rhythm disorders. When there is a sodium-potassium imbalance with predominant sodium, arterial hypertension is the result. A potassium deficiency is more likely to arise in the following situations:
- The use of a variety of different medicines, such as diuretics.
- Physically demanding careers.
- Sweating profusely while exercising in hot climates.
- Conditions that affect the digestive absorption of the mineral, such as Crohn’s disease.
- Eating disorders.
- Smoking
- Alcohol and drug abuse.
Increased need:
- Excess sodium: when a great deal of sodium is taken in due to a diet rich in meat derivatives, preserves, and salt-preserved foods, the need for potassium increases. This is because there must be a sodium-potassium balance in the blood, all body fluids, and, by extension, foods.
- Loss through body fluids rich in potassium: intense vomiting or diarrhea, polyuria (excess urine production).
Potassium loss during the processing of foods: Only that dissolved in the cooking water.

How Much Potassium Per Day
The amount of potassium daily depends on various factors, including how healthy you are, ethnicity, and activity level. However, this mineral has no RDI, so health officials from the World Health Organization (WHO) and other countries such as Spain, Mexico, Belgium, and the UK recommend ingesting at least 3500 mg daily with high potassium foods.
On the other hand, countries such as Canada, South Korea, Bulgaria, and the USA recommend ingesting at least 4700 mg per day via meals on the potassium-rich foods chart. However, consuming more than 4700 mg daily has no added health benefits.
However, there are quite a few groups of individuals that can benefit immensely from meeting the higher recommendation, such as:
- African Americans: According to studies, consuming 4700 mg of potassium daily can eliminate salt sensitivity, a common condition among African Americans.
- Athletes: These people are susceptible to significant potassium loss through excessive sweating.
- High-risk groups: People suffering from kidney stones, osteoporosis, stroke, or high blood pressure can benefit immensely from consuming 4700 mg of potassium daily.
Frequently Asked Question
I know potassium-rich foods help with blood pressure, but how does it work?
Potassium has several essential roles in blood pressure regulation:
1. Relaxes blood vessel walls: It helps counter the blood vessel-constricting effects of sodium, leading to widened vessels and lower pressure.
2. Excretes excess sodium: Potassium encourages your kidneys to flush out more sodium through urine, reducing fluid volume in the bloodstream.
3. Supports cellular function: Adequate potassium is crucial for healthy muscle cells lining blood vessels, allowing them to respond appropriately to signals that regulate blood pressure.
I’ve heard that potassium-rich foods might help with bone health. Can you explain that?
Yes, there’s growing evidence that potassium supports bone health in a few ways:
1. Neutralizes acid: High-protein and sodium-heavy diets can increase acidity in the body. Potassium helps offset this acid, preventing the body from pulling calcium (needed for bones) to neutralize it.
2. May improve calcium absorption: Some studies suggest potassium-rich foods might support better calcium retention and use by the body.
3. Reduces risk of osteoporosis: Several studies have linked higher potassium intake with better bone density and decreased risk of osteoporosis, especially in postmenopausal women.
Do potassium-rich foods have any benefits for muscle function beyond preventing cramps?
Absolutely! Potassium is fundamental for all muscle functions:
1. Nerve signaling: The electrical signals that tell your muscles to contract rely heavily on potassium flow in and out of cells.
2. Energy use: Potassium regulates how muscles use glycogen (stored energy), making it crucial for sustained performance and recovery.
3. Reduces muscle breakdown: Insufficient potassium can increase muscle breakdown during strenuous activity.
Besides blood pressure management, are there any indirect benefits of potassium on heart health?
Yes, potassium’s positive influence on heart health extends beyond just blood pressure control:
1. Reduces stroke risk: Numerous studies associate potassium-rich diets with a lower risk of stroke.
2. May protect against arrhythmias: Adequate potassium levels play a role in maintaining a regular heartbeat.
3. Supports overall cardiovascular health: Potassium works with other minerals for optimized heart function.
Where can I find the best sources of potassium beyond bananas?
While bananas are a good source, here are some other potassium powerhouses:
1. Fruits & Vegetables: Avocados, sweet potatoes, spinach, leafy greens, beans, lentils, dried fruits (apricots, figs), cantaloupe, and winter squash.
2. Dairy products: Yogurt, milk (particularly low-fat options
3. Nuts and Seeds: Almonds, sunflower seeds
4. Fish: Salmon, some types of tuna
