My First Food & Nurtition Class

I just finished with my very first class, working towards becoming a Registered Dietitian. The first thing that stood out in my mind was the fact that the Professor kept ranting against a high protein diet and people who do not eat peanut butter. I felt that she was parroting the American Food Corporations talking points and agenda.
There are only 2 diets that helped me regulate my mood and weight-that is a low carb. diet or a vegetarian diet. I can understand simple carbs. but preaching for people to eat processed foods and sugar seemed a little absurd. Plus she is foreign, so I do not know if that had anything to do with her irrational positions.

I have read complaints about people who are vegetarians or whole food dieters, complaining that Dietitians do not understand anything beyond the Food Chart.
The class requires that we purchase a $160.00 book titled, "Nutrition Concepts and Controversies" 11th Ed. by Frances Sizer and Eleanor Whitney.
I look though the book and I noticed that there are advertisements for Kraft foods and even a McDonald egg McMuffin for breakfast! I even noticed a photo of a Little Debbie cup cake, on a food plan, in this book! It is almost like the junk food corporations, sat down and wrote this book themselves.
This seems more about pushing a profit driven agenda for the American food lobbyist than about getting people healthy.
This is my first impression and it's not a very good one thus far.
