| Popis: | OBJECTIVES: To assess subject perception of their level of various components of satisfaction, and changes in bowel habits, while consuming macadamia nuts during a free-living intervention study. METHODS: This was a randomized, crossover study in which free-living subjects (n = 35) were allocated to an 8 week macadamia nut (15% kcals) intervention and control (usual diet) phases. Eligibility criteria included a BMI of 25–39 kg/m,(2), abdominal obesity, and presence of at least 1 other cardiometabolic risk factor. Subjects attended a biweekly clinic with the study dietitians to receive a supply of pre-weighed daily portions of nuts (mixture of raw and roasted), instructions and reinforcement on ways to incorporate the nuts into their habitual diet. A 14-item macadamia nut satisfaction questionnaire was administered at the end of the study, to assess various factors including perceptions of taste, ease of use, ease of preparation of the nut, and fullness. A 9-item bowel habits questionnaire was administered at the end of both the treatment and control phases, assessing factors including bowel frequency, perceptions of change in digestion, and stool consistency, using the Bristol Stool chart. Subject responses to the satisfaction questionnaire were calculated as proportions. Bowel movement frequency, and stool type were compared between the macadamia nut and control phases using the Wilcoxon signed rank sum test. RESULTS: Most subjects liked the taste (89%) of macadamia nuts, found the nuts easy to use (95%), and incorporate (95%) into their daily diet, and did not feel deprived (86%) while eating macadamia nuts. About half of the subjects felt strongly that macadamia nuts added flavor and variety to their diets, and 80% really liked including macadamia nuts into their habitual diet. In terms of bowel function, no significant difference in bowel movement frequency was noted between the macadamia and control phases. Stool consistency (Bristol stool assessment) was significantly different between the macadamia and control phases (P = 0.049). CONCLUSIONS: Most subjects indicated favorable perceptions towards, and satisfaction with macadamia nuts. Self-reported stool consistency was different between the macadamia and control phases.
