Back in the 1980s, when it came to healthy eating, the bottom line in nutrition was always that people should “eat a wide variety of foods.” This idea came to mind while reading the recent study by Bahrami et al that looked for correlation between dietary diversity scores and risk of colorectal cancer.1
Bahrami recruited patients newly diagnosed with colorectal cancer (n=129), or colorectal adenoma (n=130) along with 240 controls. Food frequency questionnaires were used to gather information about usual diet prior to diagnosis and from that information Dietary Diversity Score (DDS) was calculated for each participant.
