Eating four or more servings of potatoes a week is associated with a significantly increased risk of hypertension, according to three studies, which followed over 187,000 doctors and nurses for more than 20 years.
The results showed that eating baked, boiled or mashed potatoes at least four times a week appeared to increase the risk of hypertension by 11%, while eating French fries increased the risk by 17% compared to those who ate less than one serving of these per month. These statistical associations remained, even after adjusting for total dietary intakes of sodium, potassium, magnesium, calcium, fibre and dietary fats, and after taking people’s weight and age into account.
Certainly you don't want to eat four or more servings a week.
