High fiber di­ets avert heart dis­ease, di­a­betes – study

Tempo - - News -

– Peo­ple who eat lots of high-fiber and whole grain foods have lower risk of heart dis­ease, stroke, di­a­betes and other chronic dis­eases than peo­ple whose di­ets are low in fiber, a study com­mis­sioned by the World Health Or­ga­ni­za­tion (WHO) says.

For ev­ery 8 gram in­crease in fiber eaten a day, to­tal deaths and in­ci­dences of heart dis­ease, type 2 di­a­betes and bowel can­cer fell by 5 to 27 per­cent, the study said. Pro­tec­tion against stroke and breast can­cer also rose.

A good tar­get for those want­ing to reap health gains would be to eat 25g to 29g of di­etary fiber a day, the anal­y­sis found. But the data, pub­lished in a se­ries of sys­tem­atic re­views and meta-analy­ses in The Lancet med­i­cal jour­nal, also sug­gested higher di­etary fiber in­takes could give even greater pro­tec­tion.

“Our find­ings pro­vide con­vinc­ing ev­i­dence for nu­tri­tion guide­lines to fo­cus on in­creas­ing di­etary fiber and on re­plac­ing re­fined grains with whole grains. This re­duces in­ci­dence risk and mor­tal­ity from a broad range of im­por­tant dis­eases,” said Jim Mann, a pro­fes­sor at the Univer­sity of Otago, New Zealand who coled the re­search.
