Abstract
Learning Outcome: The present study examined the amount of vitamin D consumed from milk-based coffee beverages in order to determine the level that beverages are contributing to overall DRI requirements for vitamin D.
Background: Students may not be getting adequate amounts of vitamin D from foods/beverages they choose to consume, including coffee drinks. Unfortunately, vitamin D deficiency remains a medical concern to both children and adults (Hollick, 2007).
Methods: The researcher obtained standardized measures for the amount of milk used in each coffee beverage; 6/8, 10/12, 12/16, 16/20 ounces, respectively. Skim, 1%, 2%, and whole milk were analyzed. A convenience sample of 107 Midwestern university students were recruited. The Beverage Intake Questionnaire (BEVQ-15) was adapted to reflect milk-based coffee beverages. The survey was administered outside one of the university coffee shops. All (n=107) questionnaires were coded, then analyzed using descriptive statistics.
Results: Vitamin D consumed from milk-based coffee beverages (i.e. latte, mocha, cappuccino, flat white, macchiato) contributed to the DRI standard of 600 IU/day. Thirteen IU of vitamin D is found in one ounce of fluid milk. 13% (78 IU) of the DRI is found in an 8 oz. milk-based coffee beverage, 22% (130 IU) of the DRI can be found in 12 oz. beverage, 26% (156 IU) in 16 oz. beverage, and 35% (208 IU) in 20 oz. beverage. Descriptive statistics indicate a range of 14.3 IU to 920.4 IU of vitamin D with a mean of 186.8 IU (31%) of the DRI met through milk-based coffee beverages.
Conclusions: Students consuming milk-based coffee beverages contribute to their overall DRI requirements.
