Looks like too many fries could be causing a lot of adults to suffer from hypertension.  At least that’s what researchers at Brigham and Women’s Hospital and the Harvard T.H. Chan School of Public Health are saying.

According to their research, a large quantity of potatoes and fries will increase your risk of hypertension, at least in adults.  These findings were published online in the British Medical Journal.

Author Lea Borgi, MD, says “In our observational study participants who did not have high blood pressure at baseline, and consumed four or more servings a week of potatoes (boiled, baked or mashed) later had a higher risk of developing hypertension compared to those who consumed one or less than one serving a month.”

“Additionally, we found that if a participant replaced one serving of boiled, baked or mashed potato per day with a non–starchy vegetable, it was associated with a lower risk of hypertension.”

Researchers followed women and men who did not have high blood pressure at the beginning of the study.  The study was split between 62,175 women in the Nurses’ Health Study, 88,475 women in Nurses’ Health Study II and 36,803 men in the Health Professionals Follow-Up Study.

Participants had either less than one serving a month OR 4 or more servings a week.  Participants who had 4 or mores servings a week had an increased risk of hypertension – and it mattered how the potatoes were served as well.  Participants registered an 11% increased risk for boiled, baked or mashed potatoes.  The risk jumped up to 17% for fries.

For potato chip lovers there is a slightly tarnished silver lining.  The researchers did not find any association with consuming potato chips and a higher risk of developing hypertension.

That doesn’t mean it’s good practice to eat a whole bag of potato chips, but at least you can indulge once in awhile.
