Brief summary
Despite the public health recommendation to consume 30g of nuts per day, there is limited data investigating whether the recommended amount of nuts is considered acceptable to the consumer. One study reported that consuming the recommended 30 grams per day of nuts was found to be achievable and acceptable. The study population used in this research was largely European, therefore whether the results can be extrapolated to other ethics groups e.g. Maori, is unknown. In addition to measuring the acceptability of nuts, it is of equal importance to investigate the health properties of nuts. To date, there are five human intervention trials that have investigated the effect of hazelnut supplementation on plasma cholesterol levels. As the study population in the previous studies was largely European, it is of interest to compare the health effects of regular nut consumption in European and other ethnic group, i.e. Maori. The NATINATI study therefore aims to compare the acceptability of hazelnuts and the effects on blood lipids, lipoproteins, apolipoproteins, hs-CRP, glucose and insulin after consuming 30g of hazelnuts per day for four weeks among matched (age within 1 year, sex, BMI for 2 BMI points) Maori and European participants.
Interventions
This will be a single intervention, where participants will be asked to consume 30g of hazelnuts daily for four weeks. The study will be carried out to assess the effects of incorporating hazelnuts into the usual diet on blood lipids and lipoproteins, apolipoproteins, hs-CRP, glucose and insulin among Maori and European participants. This study will also examine the effects of repeated exposure to hazelnuts on participants' acceptance.
