But interestingly also a very high genetic factor with 90% of identical twins both having T2DM (which is greater than that of type 1 which if I remember correctly is 40%)
Sounds like Nature vs nurture to me. Until there is a proposed genetic marker... it's just another item confusing the public about correlation vs causation.
Looked at the first paper. I have significant concerns that, frankly, I didn't finish reading.
1. Small sample size, <20 iirc.
2. No control group at all. (There should have been a group under the same requirements and same diet)
3. They picked 'uncontrolled', and from my own experience that term is synonymous with "unmanaged." Which, translates to "patient is not compliant with treatment." As such, feeding them exclusively a vague "diabetic diet" coupled with the 5 day hospital stay- well its enough to cloud the results enough that no conclusions can be made.
4. Cont. Because people rarely intentionally make themselves feel like crap- which you will with uncontrolled type II. The hospital stay, its exposure to allegedly* diabetic friendly foods, and subsequent time for the subjects to realize "I feel better, I like this!" Basically invalidates the entire paper.
* allegedly, because I just got out of a hospital with a fantastic cafeteria. But, the "diabetic menu" had way to many items with high glycemic indexes, and nothing to maintain a steady sugar level until the next meal.
Finally:
''HbA1c was lower four weeks after the oatmeal intervention.''
