Beets
Researchers found that people with high blood pressure saw significant improvements from drinking beetroot juice. The study authors found that the nitrates in the juice brought down the participants’ blood pressure within just 24 hours.
You can juice your own beets or simply cook and eat the whole root. Beetroot is delicious when roasted or when added to stir-fries and stews.
Remember to use caution when handling beets. Their deep red color could stain your hands and clothes.
