Understanding Whole Grain Consumption among Low-Income Older Adults Using the Theory of Planned Behavior.

Older adults have low whole grain (WG) intake. This qualitative study used the Theory of Planned Behavior (TPB) to identify low-income older adults' WG beliefs. A convenience sample of 25 low-income adults 60 years and older were interviewed using questions developed based on TPB constructs: behavioral, normative, and control beliefs.
