Leafy greens v diabetes?

According to the BBC “A diet rich in green leafy vegetables may reduce the risk of developing diabetes, UK research says. The team calculated that a daily dose of 106g reduced the risk of diabetes by 14% – a UK “portion” is classed as 80g.”

The article quotes one of the study authors, Prof Melanie Davies as saying “This study suggests that green leafy vegetables seem to be particularly important in preventing diabetes.”

What did the report really find?

The team trawled through lots of existing studies on fruit and vegetable consumption v diabetes and eventually came up with 6 that met their inclusion criteria.

The trouble is, these 6 reported results that were all over the shop, and the research team struggled to explain why they were reporting such different results.

They suggested that it might be due to widely different methods used to record food consumption. And while there was a suggestion of a link between leafy greens and diabetes, even then the studies were using different definitions of what counted as a leafy green.

The report states “Summary estimates showed that consuming 1.35 servings a day of green leafy vegetables (highest intake) compared with 0.2 servings (lowest intake) resulted in a 14% reduction in risk (P=0.01) of type 2 diabetes.”

As to the possible protective mechanism of leafy greens, more research is required.
