What Kind of Oat Bran is Used in the Dukan Diet?
Dr Dukan recommends a very specific oat bran for his Dukan diet – M2bisB6 grade bran, which has been milled to just the right size and then sifted to remove the flour and as soon as possible, this special grade of oat bran will be made available in the US for purchase from his website.
But what oat bran does Dr Dukan recommend when his ideal oat bran isn’t available. His site www.dukandiet.com recommends that “you use other US brands of oat bran” The only other stipulation is that “the contents of the box say 100% oat bran (and not steel cut or rolled oats)”.
My take on this information is that you can use any brand of oat bran whilst following the Dukan Diet although Dr Dukan would of course prefer you to use his “exceptional type of oat bran” as this will provide the optimum results. If you were like me and you thought oat bran was oat bran let me explain why this isn’t the case.
The first variable in oat bran is the milling or grinding of the grain. There are three main grinds fine(3), medium(2) and coarse(1) and two ways of carrying out these grinds, simple and bis. This means that the oat can be ground into 6 different sizes and Dr Dukan considers medium(2) bis to provide the optimum size. Size matters because over grinding reduces effectiveness of the oat bran and insufficent grinding doesn’t produce optimum viscosity.
The second variable is the sifting or sieving of the ground oats. This sifting separates the flour from the bran and insufficent sifting leaves too much flour in the bran which reduces the effectiveness of the bran to help asborb fat, reduce cholesterol and combat constipation. Dr Dukan recommends 6 siftings to produce a very pure oat bran.
So Dr Dukan recommends oat bran which has been milled medium bis and sifted 6 times, or that is M2bis-B6 grade. Dr Dukan or Regime Dukan (the Dukan Diet in French) has recently registered the trademark M2bisB6 for their use and it is registered to them until 2 December 2020.
