When we hear the word “potassium,” most of us immediately think of bananas. But in reality, this metal is found in dozens of plant foods, from potatoes and beans to spinach, tomatoes and papaya. Despite its widespread presence in nature, nutrition experts warn that much of the population is not getting enough.

Loss of potassium in the heat causes premature fatigue, weakness and dizziness. Adequate potassium levels help the body adapt to heat and withstand high temperature. In addition, heat and swimming or exercising in the sun exhaust muscles. Without potassium, the muscles they can’t relax, causing painful summer cramps.

Potassium is now considered one of the nutrients of public health concern, as insufficient intake is associated with an increased risk of certain chronic diseases. The modern diet, which is increasingly based on highly processed foods, seems to be one of the main reasons why many people do not meet their daily needs.

Why is potassium so important?

Potassium is an essential metal and at the same time one of the body’s main electrolytes. Electrolytes are substances that carry electrical charge and participate in dozens of vital body functions.

Every cell in the body needs potassium to function properly. This metal contributes to:

  • In maintaining fluid balance.
  • In normal muscle function.
  • In the transmission of nerve signals.
  • In the proper functioning of the heart.
  • In blood pressure regulation.

Potassium works closely with sodium, creating the electrical impulses that allow muscles to contract and relax. This applies to both skeletal muscles and the body’s most important muscle: the heart.

The hidden problem of modern nutrition

According to experts at the Harvard TH Chan School of Public Health, one of the main reasons why many people do not get enough potassium is a low consumption of fruits, vegetables and legumes.

At the same time, the modern Western diet is characterized by a high consumption of highly processed foods, such as ready meals, salty snacks, processed meats and packaged products.

These foods present a particularly problematic nutritional profile: they contain large amounts of sodium but very low amounts of potassium. In other words, they provide the exact opposite of what the body needs to maintain its cardiovascular balance.

How to increase your potassium intake

Experts agree that the most effective way is to adopt a diet based more on natural and minimally processed foods.

Some simple practical moves are:

  • Add legumes to salads or main meals.
  • Replace some of the processed snacks with fruit.
  • Eat vegetables at every main meal.
  • Choose potatoes or sweet potatoes instead of processed side dishes.
  • Include more yogurt and fish in your weekly diet.
