The intake of vegetables in the US remains below the recommendation in the Dietary Guidelines for Americans; particularly intake of cruciferous vegetables is often low, due to their bitter taste. The aim of this ongoing study is to examine if added spice mixtures can offset taste aversions and increase the intake of different vegetables including the cruciferous vegetables broccoli and cauliflower. Methods Twenty healthy overweight adults (BMI: 25–30 kg/m2) with a daily intake of less than three servings of vegetables are enrolled, ensuring equality between sexes and between high and low restraint eaters, defined by the Three Factor Eating Questionnaire (TFEQ‐R21). At a total of 10 visits, a random selected vegetable, with or without added spices, is served in quantities sufficient to test intake, and a computer‐based system modified from the Universal Eating Monitor (UEM) is used to measure total food intake (g), meal duration (min) and eating rate (g/min), and to obtain VAS scores to assess sensory and hedonic qualities of the vegetable, and ratings of appetite and mood. Results Method feasibility and preliminary observations have been obtained. Final statistical analysis is pending. Perspective The UEM method can give valuable information on whether simple approaches as addition of spices, potentially can increase vegetable intake as recommended by the Dietary Guidelines for Americans.
