The Claim
In middle-aged and older adults with overweight or obesity, daily consumption of 70 mL of red beetroot juice increases circulating nitrate and nitrite concentrations by approximately 2.5-fold compared to placebo or nitrate-free beetroot juice, but does not improve vascular endothelial function as measured by reactive hyperemia index (RHI) or consistently alter postprandial cardiometabolic responses to a high-fat meal.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In middle-aged and older adults with overweight or obesity, drinking 70 mL of red beetroot juice daily raises nitrate and nitrite levels in the blood by about 2.5 times compared to a placebo, but does not improve blood vessel function or consistently change metabolic responses after a high-fat meal.
See the scientific wording
In middle-aged and older adults with overweight or obesity, acute and chronic consumption of 70 mL of red beetroot juice daily increases circulating nitrate and nitrite concentrations by approximately 2.5-fold compared to placebo or nitrate-free beetroot juice, but does not improve vascular endothelial function as measured by reactive hyperemia index (RHI) or consistently alter postprandial cardiometabolic responses to a high-fat meal.
When someone drinks beetroot juice, the nitrate in it gets absorbed, moves into saliva, and is turned into nitrite by bacteria in the mouth. The nitrite is swallowed and becomes nitric oxide in the blood, which relaxes blood vessels and lowers stiffness, but this does not improve how well the inner lining of blood vessels responds to demand.
What the research says
1 studyDrinking 70 mL of beetroot juice every day for a month boosts certain chemicals in the blood, but it doesn’t make blood vessels work better or improve how the body handles a fatty meal in older adults with extra weight.
