Potassium is Vital for Human Health
Potassium is essential for human health. We ingest it in our food, and a balanced diet will generally provide healthy humans with sufficient potassium. Potatoes are an important source of potassium, as they are a common side dish on many dinner tables, several times a week. Other foods with particularly high potassium contents are vegetable and fruit juices, bananas, pulses, avocados, fennel, kale, spinach and mushrooms. Red (muscle) meat, muesli and whole wheat bread are also great sources of potassium. Vegetables should not be cooked longer than necessary. Otherwise their potassium content will leach into the water and will be poured down the drain.
Where and How Potassium Works
98 % of our body’s potassium content is stored within our cells. It is vital for transferring impulses from nerve to muscle cells. Potassium also plays an important role in maintaining normal blood pressure. It also influences the release of hormones (e.g. insulin) and is required for protein building and for carbohydrate utilisation. Together with sodium, potassium is tremendously important for the regulation of the cells’ membrane potential. A lack of potassium may cause fatigue, tiredness, muscle weakness and constipation. Pronounced deficiencies may even cause disturbances of consciousness and cardiac irregularities.
