Dutching has nothing to do with fat. You can find high-fat and low-fat versions of both dutched and natural cocoa. I'm not sure about health differences.
Hi Luk3, the dutch process make it less acidic along with making it easier to mix with milk and other liquids. We find it tastes better too. The fat content has nothing to do with the dutch processing. The higher fat content found in our cocoa powder will have more of the good nutrients and protective properties along with tasting much better then the lower fat versions.
Hope that helps! If you have any more questions please let us know.
Thanks for the replies. I read somewhere that the fat content is often lowered in non-alkalised cocoa—perhaps not.
