Eating leafy greens such as rocket and lettuce can help head off a heart attack say researchers at the University of Pittsburgh. The leaves contain nutrients which help prevent and repair damage to the heart and circulatory system.
Greens increase levels of nitric oxide, a molecule crucial to cardiovascular health. Low levels are associated with an increased risk of heart disease but treatments such as bypass surgery and angioplasty can add to the damage by disrupting the chemical pathway our bodies use to harness nitric oxide.
However researchers found the body can get around this damage by creating an alternative source from the nitrates in leafy greens.
Low levels of nitric oxide are also a risk factor for diabetes so their findings may also explain why a diet rich in fruit and veg has also been linked to a reduced risk of blood sugar problems.
