Nutrient intakes, vascular and cognitive function were assessed at baseline and at the end of each 12-week phase. Differences between the ends of each phase were compared by general linear repeated measures ANOVA controlling for baseline. Pearson's correlation analyses determined relationships between differences in cerebrovascular reactivity (CVR) and cognitive function. Results: Intakes of bioactive nutrients increased during the peanut phase. CVR was 5% greater in the left middle cerebral artery (MCA) and 7% greater in the right MCA. Small artery elasticity was 10% greater after peanut consumption; large artery elasticity and blood pressure did not differ between phases. Measures of short-term memory, verbal fluency, and processing speed were also higher following the peanut phase; other cognitive measures did not change. Differences in CVR in the left MCA correlated with differences in delayed memory and recognition. Discussion: Regular peanut consumption improved cerebrovascular and cognitive function; increased intakes of bioactive nutrients may have mediated these improvements.]]> Wed 17 Nov 2021 16:31:08 AEDT ]]> Effect of 12 weeks high oleic peanut consumption on cardio-metabolic risk factors and body composition https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22884 vs. a nut free diet on adiposity and cardio-metabolic risk markers. In a randomised cross-over design, 61 healthy subjects (65 ± 7 years, body mass index (BMI) 31 ± 4 kg/m²) alternated either high oleic peanuts (15%-20% of energy) or a nut free diet for 12 weeks. Body composition and mass, waist circumference, C-reactive protein (CRP), lipids, glucose and insulin were assessed at baseline and after each phase. Repeated measures analysis of variance (ANOVA) compared the two diets. Consistent with other nut studies, there were no differences in lipids, CRP, glucose and insulin with peanut consumption. In contrast, some reports have demonstrated benefits, likely due to differences in the study cohort. Energy intake was 10% higher (853 kJ, p < 0.05), following peanut consumption vs. control, attributed to a 30% increase in fat intake (p < 0.001), predominantly monounsaturated (increase 22 g, p < 0.05). Despite greater energy intake during the peanut phase, there were no differences in body composition, and less than predicted increase (0.5 kg) in body weight for this additional energy intake, possibly due to incomplete nutrient absorption and energy utilisation.]]> Wed 11 Apr 2018 11:43:58 AEST ]]> The addition of peanuts to habitual diets is associated with lower consumption of savory non-core snacks by men and sweet non-core snacks by women https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31420 P < .001], 9% for women [P < .001]) during the peanut phase. Body weight was 0.5 ± 0.2 kg (P = .010) greater during the peanut phase. Snacking occasions increased during the peanut phase (53% for men [P = .001] , 14% for women [P = .01]). Servings of other snack foods did not change during the peanut phase (P = .6) compared with control. However, sex-specific analysis revealed that men and women consumed less savory (P < .001) and sweet (P = .01) non-core snacks, respectively, during the peanut phase. Despite increased energy intake and snacking frequency, peanuts may improve the diet through sex-specific reductions of non-core foods; for optimal energy balance, peanuts should be substituted rather than added to the diet.]]> Sat 24 Mar 2018 08:43:54 AEDT ]]> Lower energy intake following consumption of Hi-oleic and regular peanuts compared with iso-energetic consumption of potato crisps https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20809 Sat 24 Mar 2018 08:05:58 AEDT ]]> Nut consumption for vascular health and cognitive function https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20512 Sat 24 Mar 2018 07:59:05 AEDT ]]>
