Interpretation Introduction

Interpretation:

To explain why the high-carbohydrate diets were popular back in 1970.

Concept Introduction:

The dietary pyramid has been changing in the last years, and this is mainly to address common health problems in society. For instance, back in the 1970s, the carbohydrate content in a recommended diet was very high, as it was associated with lots of grains, bread and pasta consumption. There was little known about the effects of complex carbohydrate on the long run, for example, the increase in obesity and diabetes.
