    A deep dive into Australia's nut industry

    To celebrate Nut Day on 22 October, this episode of The Healthy Handful takes a behind-the scenes look at Australia's diverse and growing nut industry - from the regions where different nuts thrive, to how they're harvested, processed and brought to consumers. Host Belinda Neville is joined by Clare Hamilton-Bate, Secretariat of the Australian Nut Industry Council and former CEO of the Australian Macadamia Society, for a fascinating look at the people, places and processes behind Australia's nuts. The episode dives into the size and diversity of the Australian nut industry, the different regions and growing conditions that suit different nuts, and Australia's role in the global nut market through both exports and imports. Clare also shares insights into sustainability in nut production, including how growers are working to use resources more efficiently and improve environmental outcomes. Key takeaways Australia is the seventh-largest tree nut producing country in the world, with a farm-gate value of around $1.6 billion. There are seven commercial tree nut industries in Australia - almonds, macadamias, walnuts, pistachios, pecans, chestnuts and hazelnuts. Plus peanuts, which are technically a legume. Nuts are grown across many parts of Australia, from almonds in inland regions to macadamias along the east coast. Australia produces nuts for both the domestic and international markets, while also importing nuts to meet consumer demand. Sustainability is an important focus for growers, including water efficiency, soil health, resource use and reducing waste.

    Nut consumption and the risk of hypertension - RESEARCH REVIEW SERIES

    High blood pressure, or hypertension, is one of the world's most common health concerns, affecting more than 1.4 billion people globally. In Australia, around 39% of adults are estimated to have hypertension - equivalent to approximately 7.2 million people. Hypertension is also a major contributor to the global burden of disease, accounting for around 7.8% of total disability-adjusted life years. In this Research Review Series of The Healthy Handful, we take a deep dive into a new systematic literature review and meta-analysis by Metoudi et al., published in the British Journal of Nutrition. This review provides the most recent assessment of the evidence examining whether nut consumption can influence blood pressure.

    Food for thought - Eating for brain health

    Dementia is one of Australia's greatest health challenges, with a profound impact not only on those living with the condition, but also on families, carers and the broader healthcare system. While age remains the greatest risk factor, growing evidence shows that lifestyle - including what we eat - can play an important role in supporting brain health and reducing dementia risk.  In this episode of The Healthy Handful, host Belinda Neville speaks with Professor Catherine Itsiopoulos - one of Australia's leading experts in nutrition and the Mediterranean diet - about the relationship between diet, brain health and dementia prevention.  Together, they explore why healthy dietary patterns matter for maintaining cognitive function, the evidence supporting the Mediterranean diet, and how foods such as nuts, extra virgin olive oil, vegetables, legumes, whole grains and fish work together to nourish the brain.   Catherine also discusses how diets rich in highly-processed foods, saturated fats and added sugars may contribute to inflammation, vascular damage and cognitive decline over time.  Key takeaways: Cognitive decline and the risk of dementia can be reduced by at least a third through modifiable risk factors. The Mediterranean dietary pattern is one of the best-studied eating patterns for promoting brain health and reducing the risk of cognitive decline. Nuts are an important component of the Mediterranean diet, providing healthy fats, antioxidants and other nutrients that support brain health. Diets rich in highly-processed foods and low in nutrient-rich whole foods may increase inflammation and negatively affect long-term cognitive health.

    Improving the HSR for nuts

    The Health Star Rating (HSR) system is a valuable front-of-pack nutrition labelling tool designed to help consumers compare packaged foods and make healthier choices. But how accurately does the HSR reflect the healthfulness of core foods? And how well does it align with dietary guidance and nutrition evidence? In this re-released episode, Associate Professor Sara Grafenauer shares insights from her 2025 research, which explored three evidence-based modelling scenarios to apply to the HSR algorithm. The research examined how the current system scores nuts and nut-containing foods, identified areas where some nuts may be disadvantaged because of their naturally occurring energy and saturated fat content, and evaluated potential changes to improve alignment with current dietary guidance and nutrition evidence. Sara highlights potential unintended consequences of the current system, discusses the findings from the modelling scenarios, and explains how thoughtful refinements to the algorithm could strengthen public trust and confidence in the system, while better recognising the nutritional value of whole foods. Key take-outs: ·  The current HSR algorithm may not always reflect the overall health value of some nuts, despite their well-established role in healthy dietary patterns. ·  Simple, evidence-based refinements to the algorithm could improve alignment with contemporary nutrition science and dietary guidelines. ·  As the HSR system evolves, ensuring it accurately represents nutrient-dense whole foods will help maintain consumer trust and confidence in front-of-pack nutrition labelling. ·  Mandatory HSR should reinforce, not complicate, advice to eat recommended core foods.

    Diet and the gut microbiome

    In this episode, we speak with gut microbiome researcher, Dr Matthew Snelson to unpack the fascinating and rapidly-evolving science of the microbes that live within our digestive system. Together, we explore how the gut microbiome develops - from early life through adulthood - and the dietary factors that shape its composition. Dr Snelson explains what current research tells us about dietary patterns that support a diverse and resilient microbiome, highlighting key nutrients and food groups that appear to promote beneficial microbial changes.  Finally, Matthew walks us through insights from a recent review paper examining the relationship between nut consumption and gut microbiome composition, discussing how nuts may influence microbial diversity and the production of beneficial metabolites. This conversation offers a clear, evidence-based look at how everyday food choices can shape the ecosystem inside our gut - and what that can mean for overall health. Key take-outs: The gut microbiome develops across the lifespan - our microbial community begins forming early in life and continues to evolve over time. Diet is one of the strongest modulators of the microbiome - dietary patterns rich in plant foods and fibre help support a more diverse and resilient microbial ecosystem. Nuts may support gut health - emerging research suggests that regular nut consumption can influence gut microbiome composition and may increase beneficial microbial activity. Everyday food choices matter - small, consistent dietary habits can shape the gut microbiome over time, with potential implications for overall metabolic and digestive health. Access episode webpage: https://www.nutsforlife.com.au/resource/episode-58-diet-and-the-gut-microbiome/  About today's guest Dr Matthew Snelson is an Advanced Accredited Practicing Dietitian and Vice Chancellor's Research Fellow in the Nutrition & Health Innovation Research Institute at Edith Cowan University. He is interested in how dietary interventions can influence the prevention and management of chronic diseases - such as hypertension, heart failure, diabetes, and kidney disease - through modulation of gut homeostasis.
