Beetroot juice changed oral bacteria in older adults, lowering blood pressure. The results highlight dietary nitrate as a potential tool for healthier ageing. The ability of nitrate-rich beetroot juice to lower blood pressure in older adults may be linked to measurable shifts in the community of bacteria living in the mouth, according to the largest […]



Summary

A study found that beetroot juice consumption in older adults altered their oral bacteria, leading to lower blood pressure. This effect is attributed to dietary nitrate in the juice, which appears to influence the oral microbiome. The changed bacteria likely contribute to the conversion of nitrate into nitrite, a compound known to widen blood vessels. This suggests that incorporating nitrate-rich foods like beetroot into the diet could be a simple and effective way to promote healthy aging and manage blood pressure.
