Meat And Dietary Pattern Study

HS68-Meat And Pattern Study

The objective of this study is to investigate how different types of meat consumed with two different dietary patterns affect risk for disease.

Association studies have suggested that dietary meat intake may have negative impacts on health. However, these association studies have done a poor job separating meat intake from overall dietary pattern, as well as isolating effects of processed meat from minimally processed meat. Meat is a good source of several essential nutrients, including high quality protein, iron, and vitamin B12. This dietary intervention is designed to investigate the effects of minimally processed meat and further proceeded meat, as part of two different dietary patterns (the typical American dietary pattern and Dietary Guidelines dietary pattern) on outcomes related to chronic diseases.
