Top 10 Paleo Foods Rich in Potassium & Potassium Benefits

Potassium is an essential mineral and electrolyte in the body. It is essential, meaning it must be supplied by the diet daily.

Potassium is needed to regulate blood pressure and heart beat rhythms, maintain fluid balance, transport nutrients and help muscles contract and nerves function.

Most people are significantly low in potassium and eating less than the recommended daily amounts set forth by dietary guidelines.

This creates a problem for health.

Below is a list of paleo-approved foods that are rich in potassium along with accompanying potassium-boosting recipes. Give them a try!

What is potassium?

Potassium is an essential mineral meaning it must be supplied by the diet in amounts greater than 100 mg per day (“macro”= big quantities).

Potassium is a mineral located inside the cells.

It is found in all living cells, in both plants and animals, which is why it is most abundant in fresh foods.

About 85% of potassium is absorbed from the diet.

Potassium and sodium regulate fluid balance.

Unlike sodium, which Americans tend to get enough of (or too much of) in the SAD (standard American diet) diet, potassium is found in foods that many people are failing to consume in adequate amounts.

Processed foods like canned soups or frozen meals tend to be low in potassium and high in sodium.

A heart-healthy goal is to eat more naturally fresh foods (to increase potassium) and less processed foods in diet (to decrease sodium).

Potassium is important and the kidneys tightly control its levels.

It is recommended that adults get more than 4,700 mg of potassium per day. On average, we get way less than is recommended.

Diets high in potassium and low in sodium increase chances of high blood pressure and increase risk of death from heart disease. Higher levels of potassium can reduce risk of high blood pressure, stroke, heart disease and death.

This is why it is important for people to monitor their mineral levels with advanced testing.

What are the benefits of potassium?

  • Lower chance for getting kidney stones
  • Lower risk for muscle cramps
  • Helps muscles function properly
  • Promotes quality sleep and relaxation
  • Enhances bone health 

Why is it potassium good for the heart?

  • Helps to lower blood pressure by relaxing blood vessel walls
  • Normalizes heart rhythms by controlling electrical activity of the cardiac muscle
  • Decreases chances of stroke, high blood pressure, heart disease and death 

How much potassium do we need?

The Institute of Medicine (IOM) recommends adults get at least 4,700 mg per day of potassium. 

Who is most at risk for low potassium levels?

  • People taking diuretic medication
  • People who have kidney or adrenal disorders
  • People who take laxatives
  • People who don’t eat enough calories
  • Diabetics
  • People who exercise greater than 2 hours per day
  • People who have been sick (vomiting or diarrhea)
  • Alcoholics
  • Sauna users

Should I supplement?

Yes.

Due to most Americans existing on a Standard American Diet (or SAD), they continue to take in excessive amounts of sodium and low amounts of potassium.

Additionally, there are many at-risk groups for potassium deficiency based on life status, disease risk or medications. There are many reasons why nutritional supplementation is often needed.

Check out scientifically formulated Potassium Boost that we use in our office. It contains 1,200 mg of elemental potassium and 120 mg of elemental magnesium per serving. It helps to maintain healthy blood pressure and heart rhythms. It also supports muscle function, alleviates muscle cramping and enhances bone health.

We get excellent results with our patients using the powder. Most products are small dose capsules.

Note: People with kidney problems, or issues with handling potassium should be cautious about increasing potassium intake. Be sure to talk to your doctor before making any changes to your diet or supplement routine.
