Diabetes Risk: Cereal Good, Veggies Not?

Okay, I have to admit. This article made me say, “Henh?” According to new research cereal fiber and magnesium can reduce the risk of type 2 diabetes, but, fruits and vegetables don’t. Yeah, I don’t get it either. Reuters reports:
The findings stem from an analysis performed by Dr. Matthias B. Schulze and colleagues from the German Institute of Human Nutrition Potsdam-Rehbruecke, Nuthetal. The study involved over 25,000 adults, between 35 and 65 years of age, who were followed from 1994 to 2005 for diabetes. A food-frequency questionnaire was used to assess the participants for the amounts of dietary fiber and magnesium.


During follow-up, 844 subjects developed type 2 diabetes, the report indicates. Compared with the subjects with the lowest cereal fiber intake, those with the highest intake had a 28-percent reduction in diabetes risk.

Fruit and vegetable fiber intake, by contrast, did not affect the risk. Magnesium intake also showed no effect in this study.
Obviously this flies in the face of a lot of the things we discuss here on DiseaseProof. So for rebuttal, I decided to call in heavy reinforcements. Here’s what Dr. Fuhrman had to say about this study:
The reason for the findings is a huge variance in the amount of whole grain fibers consumed from none to a significant amount. This does make a big difference, especially since people who do not consume whole grains generally live on sugar and white flour. But since the level of vegetable consumption in the highest quintile was still relatively low by our standards there was not really a representative group with a high consumption of green vegetables.


So all this means is that whole grains are better than refined grains and that that change in a person's diet has a major implication for diabetic causation and treatment. It does not mean that green vegetables, beans, nuts and seeds are not likewise protective because the population tested still did not eat much of these foods.
