@nealkshah: A single glass of beet juice can DROP your top blood pressure number by up to 10 points in just 3 hrs. But one common bathroom habit CANCELS it completely. That habit is antibacterial mouthwash, and here is the strange reason why. The nitrates in beets do not lower your blood pressure on their own. First, friendly bacteria living on your tongue have to convert them, step by step, into nitric oxide, the gas that relaxes and widens your arteries. Swish with an antiseptic rinse and you kill those bacteria, turning your beet juice into expensive red water. With regular use, that mouthwash may even nudge your baseline blood pressure up a few points. The drop from beets is real, with studies in the American Heart Association journal Hypertension showing roughly a 4 to 10 point fall in the top number, starting within an hour and lasting up to a day. It matters most after 50, when arteries naturally stiffen. A few honest warnings: skip it if you get kidney stones, since beets are high in oxalates, and never mix it with nitrate heart medications or drugs like sildenafil. Whole beets and leafy greens like arugula give you the same benefit with fiber and far less sugar than bottled juice. Never start, stop, or change a medication without your doctor. Have you tried beet juice? Tell me in the comments. #BloodPressure #BeetJuice #HeartHealth
