A study published in the American Journal of Hypertension looked at how olive oil might affect blood pressure in young women with mild high blood pressure. Spanish researchers compared a diet of polyphenol-rich olive oil to a diet that didn't contain any polyphenols and their effects on blood pressure over a period of four months. The results: The polyphenol-rich olive oil was linked with drops in systolic and diastolic blood pressure—especially among women with higher blood pressure to start.
7. Cut down on sodium intake: Processed and packaged food needs to go out of your kitchen, if you want healthy levels of blood pressure. This is because processed food is loaded with added preservatives to increase their shelf life. Also, prepare your food with lesser salt as high intake of salt is linked to risks of high blood pressure and stroke.
A study published in the American Journal of Clinical Nutrition looked at how eating whole grains affected blood pressure in middle-aged people. British researchers compared a diet of whole wheat (or whole wheat plus oats) to a diet of refined grains. They found that eating three servings of whole grains was linked with a reduction in systolic blood pressure. Exactly why isn't clear, athough other research has pointed to beneficial effects of whole grains on cholesterol.
In one study it was reported that those who consumed ACV daily per protocol showed an increase in calcium uptake. This increase in calcium uptake decreases the release of renin. Consequently, this lowered blood pressure by decreasing the activity of the renin-angiotensin system. Because of this, the scientist in this study believed that it would benefit people greatly to include ACV in their diet.
For a study in Nutrition Journal, Australian researchers looked at the effects of beet juice on blood pressure among healthy men and women. Participants drank either beet plus apple juice or plain apple juice, then had their blood pressure monitored over 24 hours. The results: The researchers observed a reduction in systolic blood pressure six hours after participants drank beet juice, especially among the men. Beets naturally contain nitrates, which ease blood pressure.
