An online survey was sent to 473 Registered Dietitians (74%) and other nutrition professionals (26%) (non‐RDs, health coaches, holistic practitioners, etc.) in Arizona. The purpose was to assess knowledge of the efficacy of functional foods and common medications prescribed to lower cholesterol and control postprandial hyperglycemia in persons with T2DM. Respondents were asked to rank: statins, dried beans, oatmeal, soy protein, and red wine for their effectiveness in lowering LDL cholesterol. Only 65% ranked statins first and 47% ranked oatmeal second. Beans are clinically more effective than oatmeal but were ranked 3rd by 38% with red wine and soy ranking 4th and 5th. Significant differences were observed by training category with RDs having more accurate knowledge than non‐RD nutrition professionals. A similar pattern was observed with responses for T2DM treatments. Overall, 71% ranked metformin 1st, with beans ranked 2nd, cinnamon 3rd, vinegar 4th, and red wine in 5th place for efficacy. Significant differences by professional category were seen for metformin (57% Non‐RDs vs. 76% RDs), beans (31% Non‐RDs vs. 50% RDs), and cinnamon (28% Non‐RDs vs. 38% RDs). Knowledge differences by professional training are not surprising, but it is cause for concern when only 71% and 76% of RDs think statins and metformin are the most effective options. RDs were more knowledgeable than non‐RDs, but large gaps and misperceptions about functional foods vs. medications for controlling hypercholesterolemia and postprandial hyperglycemia warrant greater outreach and education efforts by nutrition educators for clinicians as well as consumers.
