what foods dilate blood vessels
Berries and other fruits that are rich in antioxidants called polyphenols may help to dilate your arteries. An animal study published in 2009 in the Journal of Medicinal Food reported that cranberry juice had relaxing effects on the arteries similar to those of red wine.
Foods With Potassium. Research published in the American Journal of Physiology in 2007 found that high-potassium diets may help dilate blood vessels and reduce your risk of stroke. Although the results are not conclusive and further study is needed, it is important to get adequate potassium in your diet.
Some evidence suggests the antioxidants in tea can help prevent the build-up of fatty deposits in the arteries, act as anti-blood clotting agents and improve blood vessel dilation to allow increased blood flow.
