Colourful vegetables lower asthma risk
Colour is always pleasurable to the eye and so are coloured veggies for the body.

According to a study led by Dr. Isabelle Romieu of the National Institute of Public Health in Cuernavaca, Mexico, it has been found that women consuming plenty of tomatoes, carrots and leafy greens appear less likely to have asthma.

This is as per a report in the medical journal Thorax. Still, it's uncertain whether the foods are the reason, the findings suggest that some vegetables may protect against adulthood asthma.

Carrots, tomato juice and spinach contain nutrients called carotenoids, some of which are converted into vitamin A in the body. Among other jobs, vitamin A helps regulate the immune system and maintain the lining of the respiratory tract.

An analysis of data of nearly 69,000 French women, who were surveyed about diet and other health factors, was done. Overall, 3 percent reported having asthma, with women who ate the most carrots, tomatoes and leafy vegetables being less likely to have the lung disease.

Among the women surveyed, those who reported the highest intake of leafy greens - mostly spinach and lettuce - were 22 percent less likely to say they had asthma than women with the lowest intakes. Similarly, carrot lovers had a 20 percent lower risk of the disease, while tomato fans had an 18 percent lower risk.

However, the researchers point out, they cannot rule out the possibility that higher intakes of carrots, tomatoes and leafy greens are simply a sign of a generally healthier diet - and not a special effect of these foods specifically.

Further probing in this issue is needed to come out with strong evidence.
