This cross-sectional study is based on data from questionnaires. Anthropometric measurements were collected by trained professionals. 54720 Danish men and women aged 50-64 years participated. Intake of wholegrain products was associated with intake of fish, red meat, poultry, processed meat, dairy products, fruits, vegetables, cakes and refined-grain products. The strongest positive associations were seen for intake of vegetables and processed meat, whereas the strongest negative associations were seen for intake of red meat and refined-grain products. Wholegrain intake was also positively associated with cycling, taking dietary supplements and high school education, and negatively associated with intake of alcohol, BMI and smoking.
