Drink Beet Juice to Lower Blood Pressure Hypertension is a global disease that particularly affects people in low-income communities, but a new study by the UK University of Nottingham suggests that beetroot juice may be a practical solution for people with high blood pressure that have little access to diagnostic help or money for medication. Researchers divided 47 people between 50 and 70 years of age in Tanzania into three groups. For 60 days, one group drank nitrate-rich beetroot juice and folic acid; another was given nitrate-rich beetroot juice and a placebo; and the third drank nitrate-depleted beetroot juice. The researchers found that systolic blood pressure dropped by 10.8 millimeters (mm) Hg (mercury) in the nitrate-rich plus folic acid group and 6.1 mm Hg in the nitrate-rich and placebo group. Studies have shown that the high level of nitrates in beets is converted by the digestive system into nitric oxide, which relaxes and widens blood vessels.
Consider Curcumin and Nano-Curcumin for Heart Health Iranian researchers tested 90 patients undergoing elective heart angioplasty, giving one group 500 milligrams (mg) curcumin, the second group 80 mg nano-curcumin, and the third a placebo. After eight weeks, both types of curcumin significantly improved cholesterol, triglyceride and LDL-C levels. They also boosted antioxidant levels, superoxide dismutase and glutathione, and reduced C-reactive protein levels, indicating less inflammation. The nano-curcumin, however, produced even better results in five of those indexes, leading the authors to conclude that the effects of curcumin on the nano formula may be more conducive for cardiac patients due to its high bioavailability. Nano-curcumin is made through a process that encapsulates the herb, allowing it to be metabolized better.

B12 and Prenatal Supplements Gain Official Nod In updated 2020-2025 dietary guidelines, the U.S. Department of Agriculture and the U.S. Department of Health and Human Services have endorsed the specific use of certain supplements, noting that under-consumption of some nutrients among Americans is linked to health concerns. The guidelines advise that infants being fed breast milk exclusively or partially should be given a vitamin D supplement of 400 IU per day beginning soon after birth and perhaps continuing for more than a year. Women that are pregnant or planning to become pregnant should take a daily prenatal vitamin and mineral supplement. Pregnant or lactating women that follow a vegetarian or vegan diet are advised to talk to their healthcare provider about supplementation to ensure that they get adequate amounts of iron, vitamin B12, choline, zinc, iodine and omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The guidelines also state that some older adults may require vitamin B12 supplements, noting concerns over the amount of the vitamin absorbed from food.
