Inside BENEO’s new pulse plant: pioneering sustainable protein from faba beans
A recent study reveals that beetroot juice supplements may help enhance exercise capacity in patients with heart failure.
The study examined the impact of dietary nitrate in the form of beetroot juice supplements on the exercise capacity of eight heart failure patients with reduced ejection fraction, a condition in which the heart muscle doesn’t contract effectively and can’t get enough oxygen-rich blood to the body.
Researchers found that the beetroot supplement resulted in significant increases in exercise duration, peak power and peak oxygen uptake while exercising.
The data suggests that dietary supplementation may be a valuable addition to treatment for exercise intolerance among heart failure patients with reduced ejection fraction.
Multi-center trials are needed to confirm the proof-of-concept findings and to determine whether longer-term dietary nitrate treatment improves physical activity levels, quality of life and perhaps even survival in patients with heart failure with reduced ejection fraction.
