Beetroot Juice, Oral Microbiome, and Blood Pressure in Older Adults
2025-07-27
A new study reveals that the blood pressure-lowering effect of nitrate-rich beetroot juice in older adults may be linked to specific changes in their oral microbiome. Researchers found that after two weeks of consuming concentrated beetroot juice twice daily, older adults experienced a decrease in blood pressure, unlike younger participants. This effect is likely due to the suppression of potentially harmful oral bacteria, impacting the conversion of nitrate to nitric oxide, crucial for vascular health. The study suggests that encouraging older adults to consume more nitrate-rich vegetables could offer significant long-term health benefits.
