Current guidelines for nut consumption are achievable and sustainable: a hazelnut intervention
1Department of Human Nutrition, University of Otago, Dunedin, New Zealand.
Regular consumption of whole or sliced hazelnuts is highly acceptable and sustainable for long-term health benefits, supporting their role in reducing cardiovascular disease (CVD).
Area of Science:
- Nutrition Science
- Dietary Habits
- Cardiovascular Health
Background:
- Nuts possess hypocholesterolemic properties beneficial for health.
- Regular and sufficient nut consumption is crucial for realizing these health benefits.
- Assessing the acceptability of regular nut intake is important for dietary guidelines.
Purpose of the Study:
- To evaluate the long-term effects of consuming hazelnuts in different forms on 'desire to consume' and 'overall liking'.
- To determine the sustainability of regular hazelnut consumption as a dietary behavior.
Main Methods:
- A randomized cross-over study involving 48 participants.
- Four-week dietary phases of consuming 30 g/day of whole, sliced, or ground hazelnuts.
- Measurements of 'overall liking' (pre/post-exposure and daily) and 'desire to consume' (during exposure) using a visual analogue scale.
Main Results:
- Whole and sliced hazelnuts received significantly higher ratings for 'overall liking' and 'desire to consume' compared to ground hazelnuts.
- Ratings for both 'overall liking' and 'desire to consume' remained stable throughout the consumption period for all forms.
- Participants demonstrated sustained liking and desire to continue eating hazelnuts.
Conclusions:
- Regular consumption of whole and sliced hazelnuts is well-accepted and sustainable.
- Hazelnut consumption can be a viable dietary strategy to support cardiovascular disease reduction.
- Findings support public health recommendations for regular nut intake.
