BBC NEWS | Health | Beetroot juice 'boosts stamina': "Drinking beetroot juice boosts stamina and could help people exercise for up to 16% longer, a UK study suggests.

A University of Exeter team found nitrate contained in the vegetable leads to a reduction in oxygen uptake - making exercise less tiring.

The small Journal of Applied Physiology study suggests the effect is greater than that which can be achieved by regular training.

Beetroot juice has previously been shown to reduce blood pressure.

The researchers believe their findings could help people with cardiovascular, respiratory or metabolic diseases - and endurance athletes."
