This is a really interesting topic and even more interesting to read peoples views based on what they have read.
If I described the way I eat it would be primal/paleo I have done alot of reading on the subject and find that this way of eating allows me to keep me weight down effortlessly, have tons of energy and enjoy food, ( So without hijacking the thread I am a butter and olive oil cook ) We eat virtually no processed food, if I look back at my family 2 generations ago they ate fresh produce, meat dairy and lots of fat ( compared to these days ) , cooked everything from scratch, most of my relatives lived to their 80's or 90's, very few of them were over weight and they didn't have heart or sugar problems, if I compare this to the generation above me...they are overweight, have high blood pressure, diabeties etc etc start there day with a pile of pills the doctors insists they take. They have mainly the same genetics but are nowhere as healthy, the only changes are lifestyle and food, so I have stopped reading/researching past my family history as popular opinion changes with every new lot of research, so I try to eat as much as possible like my grandparents and their parents.
I would say the majority of the people on this Thermomix forum are here because they are trying to introduce more "unprocessed" foods into their diet so I think we are all doing better than the average consumer these days.
