Brief summary
The primary aim of this study is to examine the feasibility of investigating whether Australian children aged 8-13 years will consume 30g almonds on 5 days per week for 8 weeks. The secondary aim is to compare the effects of consuming almonds on cognitive function compared to a nut-free control phase. Additionally, this study aims to examine the effect of sleep quality and quantity on cognitive performance in primary school aged children. This study is an 18-week randomized, controlled cross-over feasibility study. Forty free-living healthy children aged 8-13 years (without known nut allergies) will be randomized (using a random number generator) to start in either the almond or the control phase for 8 weeks. Following a washout period for 2 weeks, children will then cross-over to the alternate condition for another 8 weeks. Children will undergo cognitive performance testing using computerized tasks five times - screening (for familiarization), and then before and after each phase. The study will be conducted by the Alliance for Research in Exercise, Nutrition and Activity (ARENA), University of South Australia. Participants will consume 30g of raw, unsalted almonds for 5 days a week. In the control phase participants will be given 250ml bottled water as an attention control. Participants will be provided with individual packets of almonds (5 days x 8 weeks = 40 packets). During the control phase participants will be asked not to consume nuts or nut products. In the almond phase participants will be asked not to consume nuts or nut products other than the almonds provided.
Interventions
This study is an 18-week randomized, controlled cross-over feasibility study. During the intervention phase (8 weeks) participants will consume 30g of almonds, 5 days a week. There will be a control phase (8 weeks) with participants consuming 250ml bottled water, 5 days a week. A washout period of 2 weeks will occur between phases.
Following a washout period of 2 weeks, children will then cross-over to the alternate condition for another 8 weeks.

Participants will be provided with individual packets of almonds. Test foods can be eaten at any time of the day as decided by the participant, and they may choose to consume them all in one sitting or throughout the day. Participants will be asked to complete a checklist to record consumption of test foods as well as to keep empty packaging to determine compliance. In the almond phase participants will be asked not to consume nuts or nut products other than the almonds provided.
