De som spiser mye frukt og grønnsaker har betydelig lavere risiko for astma og astmalignende pusteplager. Både voksne og barn som spiste mye frukt og grønnsaker hadde 46 prosent lavere risiko for astma, sammenlignet med dem som spiste lite. Dette viser en studiesammenfatning (metaanalyse) der forskerne analyserte resultatene fra totalt 42 studier, publisert i tidskriftet Nutrition Reviews.

«Twelve cohorts, 4 population-based case-control studies, and 26 cross-sectional studies published between January 1990 and July 2013 were identified.

For the meta-analysis of adults and children, the relative risk (RR) and confidence intervals (CI) when comparing the highest intake group with the lowest intake group were 0.78 (95%CI, 0.70-0.87) for fruit and 0.86 (95%CI, 0.75-0.98) for vegetables.

High intake of fruit and vegetables (RR = 0.76; 95%CI, 0.68-0.86 and RR = 0.83; 95%CI, 0.72-0.96) reduced the risk of childhood wheezing.

Total intake of fruit and vegetables had a negative association with risk of asthma in adults and children (RR = 0.54; 95%CI, 0.41-0.69).

Consuming fruit and vegetables during pregnancy had no association with the risk of asthma in offspring.

High intake of fruit and vegetables may reduce the risk of asthma and wheezing in adults and children.»
