The Claim
A single acute dose of beetroot juice containing 6.1 mmol of inorganic nitrate does not improve submaximal aerobic endurance in older adults with heart failure with preserved ejection fraction (HFpEF), despite increasing plasma nitrite levels, suggesting that chronic nitrate exposure is required for functional benefits in this population.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
Drinking one glass of beetroot juice won’t help older adults with a certain type of heart failure exercise better, even though it raises a chemical in their blood — they might need to drink it every day for a while before they see any benefit.

What the research says
1 studyThe study found that drinking beetroot juice once didn’t help older heart patients exercise longer, but drinking it every day for a week did — which is exactly what the claim said.
