Of course, french fries should be avoided because of their high content of oil and - especially - acrylamide, a carcinogenic compound that appears during high temperature cooking. But mashed potatoes and boiled potatoes are also singled out.

American researchers at Boston University have indeed demonstrated that, whatever its mode of preparation, this food is less healthy than it is said. Their study, published at the end of May 2016 in the prestigious British Medical Journal , is without appeal:

Eating more than four servings of potatoes a week increases the risk of high blood pressure by 17% , thereby ricocheting the risk of heart disease and stroke.

The tubers, however, contain potassium (420 mg / 100g), a mineral supposed to lower the tension. But it is powerless against the extremely digestible starch potatoes that rapidly increases blood glucose levels. Two hundred grams of boiled potatoes cause a peak of blood glucose equivalent to that induced by the absorption of a can of coca!

As a result, not only is overweight and diabetes in danger, but a chronic inflammatory state is developing. In the long run, it impairs the proper functioning of the blood vessels and increases tension.

Better always associate this starchy with green vegetables. Or replace it with cereals, complete if possible.
