Getting to Know the Basic Concepts of Human Nutrition: The Example of Potassium
Potassium deficiencies are associated with breathlessness, fatigue, insomnia and low blood
sugar. Potassium is essential for healthy heart muscles. Nuts and unrefined grains are good
sources of potassium. Calcium is a natural sedative. Deficiencies can cause fatigue,
nervousness and tension. Dairy products, eggs, almonds, and soyabeans are rich sources of
calcium. Magnesium is known as nature's tranquilliser and is associated with the prevention of
heart attack. Deficiencies may lead to excitability, irritability, apprehension and emotional
disorders. Magnesium is also necessary for absorption of calcium and potassium and is found in
many fruits, vegetables, seeds, dates and prunes.
