Potatoes May Raise Blood Pressure
Potatoes raise blood glucose levels much faster than similar serving sizes of many other foods, and now it seems they may elevate blood pressure, too. Researchers examined questionnaire results from nearly 200,000 adults from three U.S. studies spanning 1984–2012. None had high blood pressure at the beginning. Compared with people who ate less than one serving of potatoes a month, those who ate four or more servings a week of baked, boiled, or mashed potatoes had an 11 percent greater risk for developing high blood pressure. The risk was 17 percent higher for french fries. In contrast, replacing one serving of potatoes a day with a nonstarchy vegetable cut the risk by about 7 percent. This doesn’t prove cause and effect, however.
