Mark Seeley on a wet October and what happens to our blood pressure in winter
ACE inhibitors are often prescribed for high blood pressure. Angiotensin-converting enzyme inhibitors prevent the enzyme from producing angiotensin II in the body, which constricts the blood vessels and raises blood pressure. ACE inhibitors help relax blood vessels, preventing them from narrowing and causing high blood pressure. Researchers have found that asparagus contains an ACE inhibitor identified as 2-hydroxynicotianamine which has been shown to lower blood pressure and help preserve kidney function. Asparagus also provides many anti inflammatory and antioxidant nutrients and is an excellent source of Vitamins K, A, B1, and C, as well as folate, iron, copper, and tryptophan.
