Atherosclerosis is one of the leading causes of death in the Western world, and the heart is particularly vulnerable. According to a study from the University of Birmingham, Alabama (USA), foods that are rich in potassium such as bananas, potatoes, avocado, and almonds protect against this disease, which takes years to develop. Beware that too much salt and the use of diuretics may deplete the body’s potassium stores.

In a matter of four months only, large doses of vitamin D were able to reduce arterial stiffness in young, overweight but otherwise healthy Afro-Americans, according to a study from Georgia, the United States. The study also showed that those participants, who only took the officially recommended quantities of vitamin D, had increased arterial stiffness. This suggests that the official vitamin D recommendations are too low to prevent stiff arteries and atherosclerosis. Another thing is that dark-skinned people living at northern latitudes, overweight individuals, older people diabetics, and those who overuse sun screen are at increased risk of synthesizing too little vitamin D.
