Sweet almonds are edible, but the bitter form of the oil is commonly used as a seasoning in food. Almonds are high in protein, vitamin E, calcium, magnesium, potassium, and iron, which are beneficial to the body. Almond is a native product of the Middle East but has been planted in Europe and the US for a long time. Almonds have magnesium and potassium. When sufficient magnesium is present in the body, it flows into the bloodstream, transporting oxygen and nutrients more quickly, preventing an increase in heart rate. Almonds have much more magnesium than barley or even spinach.
