OBJECTIVES: To determine the effect of daily intake of macadamia nuts on macronutrient intake and nutrient displacement in overweight and obese adults in a randomized crossover study. METHODS: This randomized cross-over study was comprised of two phases, each lasting eight weeks. Participants (n = 35) were randomly assigned first to either the intervention (15% of calorie needs from macadamia nuts) or control (habitual diet) phase, with a two-week washout followed by the other phase. A total of six 24-hour recalls, two at baseline and two during each phase were conducted. Period adjustment t-test was used to determine the differences in macronutrient intake between the two phases. The displacement of nutrients was done by subtracting the observed intake of a particular nutrient from its’ expected intake. RESULTS: Compared to the control phase, there were marginal increases in the consumption of total energy (mean diff = 145 kcal), total fiber (mean diff = 2 g) and a significant increase in the consumption of total fat (mean diff = 35 g, P |
