Under Pressure?

"A daily dose of walnuts and walnut oil could help keep your blood
pressure from spiking during stress, according to research published
in the Journal of the American College of Nutrition. Aim for about 1.3
ounces of walnuts (nine whole) and 1 tablespoon of walnut oil per day.
Walnuts are rich in polyunsaturated fatty acids (including alpha-
linolenic acid, an omega-3), which help keep blood vessels supple and
functioning optimally.
Even everyday stress can send your cardiovascular system into over-
drive, raising your risk of heart disease.
Enjoy half of your daily intake of walnuts as a snack."
