Now I'm totally confused

I live in Germany and am attending a diabetes seminar. I got a monitor and books etc. The weird thing is that the germans say you should eat lots of carbs and very little fat. Now I fecking don't know what to do. I was concentrating on very little carbs and trying to minimise fat and was doing not too bad. My mmol was 101 this morning when we did the check so I thought that was not too bad. I also read on a german site that pretzels are the worst thing you can eat and in the book it says they have not too many calories and fat. Now I do not know which way to go.

Well I have been eating some carbs. I found a low carb bread that has only 6,2g per slice which is not too bad. They say in the book that avovados and olives are bad and most meats etc. I would say that I am doing medium carbs with low fat and it seems to be ok. I would panic at the thoughts of loads of carbs now.
