Do you like purple-skinned potatoes?

Here's an amusing little study that I had to share.  Do you like purple-skinned potatoes?  A study published in the Journal of Agricultural and Food Chemistry indicated that consuming a small amount of purple potatoes each day can lower blood pressure in people with obesity and hypertension without increasing weight.

Eighteen volunteers, most of whom were overweight with high blood pressure ate two small purple potatoes or no potatoes daily for four weeks then switched to the opposite for another four weeks.  Researchers monitored blood pressure, body weight and other health indicators.  Average diastolic blood pressure dropped by 4.3% and systolic blood pressure by 3.5% when potatoes were consumed.  Hmm.......purple potatoes are high in healthy antioxidants, but I think we need more data.  :)
