– Among individuals who were free of diabetes (either previously diagnosed or newly detected) at the start of the study, daily consumption of fresh fruit was associated with a 12% lower relative risk of developing diabetes, compared to never or rarely consuming fresh fruit.
– In those individuals who already had diabetes prior to the start of the study, consuming fresh fruit more than three days a week was associated with a 17% lower relative risk of dying from any cause and a 13%–28% lower risk of developing diabetes-related complications affecting large blood vessels (e.g., ischaemic heart disease and stroke) and small blood vessels (i.e., kidney diseases, eye diseases, and neuropathy) than those who consumed fruit less than one day per week.
Contrary to the common belief in China and many other low– and middle-income countries, fresh fruit consumption was not associated with an elevated blood glucose level in the present study, even in people with diabetes.
These findings have public health and clinical implications and provide strong evidence in support of current dietary guidelines that fresh fruit consumption should be recommended for all, including those with diabetes
Forskerne bemærker, at “this association (lavere diabetesrisiko med mere frugt) was not significantly modified by sex, age, region, survey season, or a range of other factors including smoking, alcohol consumption, physical activity, BMI, and family history of diabetes.”
Det er dog stadig “blot” et observationsstudie, så det betyder ikke nødvendigvis, at mere frugt er lig mindre risiko for diabetes. Omvendt er der mange årsagsmekanismer, der kan forklare, hvorfor frugt skulle beskytte mod diabetes, og frugt har desuden vist at beskytte mod mange andre sygdomme også. Derfor er det et stort problem, at diabetespatienter ofte tror/får at vide, at de ikke bør spise frugt.
