    International Congress of Nutrition (ICN) Key Findings

    Named one of New Zealand’s Top Women in Food & Drink, Ashley Wilson provides her take on the 2025 International Congress of Nutrition (ICN) in Paris.  We cover:  6:40 The power of connecting 9.00 Ultra-Processed Food Heated Debate12:15 Restructure Trial - Meal Texture/Eating Rate13:30 AI Digital Marketing 17:10 Sweet Tooth Trial - our taste for sweetness 20:00 What the media shows us vs the scientific evidence22:30 Jo Wicks “killer bar” PR vs Eat Lancet25:30 UN High Level Meeting & non-communicable diseases 27:20 GLP-1 & Wegovy released in NZ28:35 Heston Blumenthal, celebrity chef - Scaling down tasting menu 30:10 Wrap up One-liners you don’t want to miss: "We have just had the release of EAT- Lancet 2 which is this global report on planetary health and recommendations on how we should be eating.

We are seeing hardly any global media - just a handful of articles on the launch. In comparison, Jo Wicks is getting all of the media. It is really important we are looking to not just the media but other sources of information such as research or our dietitians - our leads in the profession, for this information, not just this the media. Because it can be really one-sided and can be related to click-bait - what’s going to get the readership.” Ashley's Top LinkedIn Follows: Ellie Hadjilucas - Founder of Nutricomms, Carrie Ruxton - PhD, Marcia Terra - IUFoST.  Support the show

    Fuelling Your Body with Omega-3: The Full Breakdown

    Omega-3 fatty acids are often praised as essential for brain health, heart function, and overall well-being—but how much do we really know about them? In this episode, we explore their benefits, best food sources, and supplementation. Are you getting enough? What’s the difference between EPA, DHA, and ALA? And do plant-based sources measure up? Tune in as we break it all down, separating fact from fiction to help you make informed choices for your health. We cover:  2:45 Deep science dive into omega-3 fatty acids and why they are important9.00 Does the omega-3 and omega-6 ratio matter?13:25 Is canola oil good for you?15:00 Food sources of omega-3 15:15 Best fish sources of EPA and DHA 18:10 Purslane weed containing omega-320:00 Conversion rate of ALA into EPA/DHA22:00 Is frozen crumbed or battered fish goof for you?26:00 Would you recommend those who don’t eat fish of a certain age to supplement with EPA & DHA? 28:00 Should we be concerned about mercury levels in omega-3 supplements and fish?29:00 Pregnancy, fish and mercury31:30 What is the intake of omega-3 in Australia and globally? What is the optimal omega-3 intake? 34:00 Optimal omega-3 for heart disease, dementia, rheumatoid arthritishttps://www.mpi.govt.nz/food-safety-home/safe-levels-of-chemicals-in-food/mercury-levels-fish/ One-liners you don’t want to miss: "18+ years are consuming between 1.2-1.6g/day of ALA & 200-500mg of EPA/DHA/DPA. The nutrient reference values (targets) for ALA for men is 1.3g/day and for women is 0.8g/day. For EPA/DHA/DPA, 160mg/day men and 90mg/day women. Based on this we are meeting them but we need more information for how much we actually need for good health; which is a little bit different to how much people need if they have a health condition like arthritis." “People talk about the ratio of omega -6 to omega -3 being about 10-12:1 in America. And in Australia they say it's sort of somewhere between And 7-5:1. So that is quite a contrasting difference. The types of oils that used in Australia are lower in omega -6 than what we find in America. And that's because in America they rely a lot more on soybean oil as one of their domestic oils.” Support the show

    The Nutrient Gaps You Didn’t Know You Had

    Are you unknowingly missing key nutrients in your diet? Dr Carlene Starck joins us to break down her Priority Nutrients research, revealing the vitamins and minerals Australians and New Zealanders are lacking. From energy to immune health, these hidden micronutrient inadequacies could be holding you back. Tune in to find out what your diet might be missing—and how to fix it! We cover:  3:00 Why this research was undertaken 6.00 Common nutrient inadequacies in Aus/NZ 8.00 Protein intake target - should it be higher? 9:45 Are the Nutrient Reference Values (NRVs) outdated? 11:45 Nutrients that have Suggested Dietary Targets (SDTs) 13:15 Methodological approach of the research 29:10 Key findings from the research31:30 Vitamin D deficiency in Aus/NZ32:30 Calcium targets, absorption and what do we know to be true about calcium and bone health and calcium and fractures. 39:20 Calcium bioavailability - how is this researched? 41:00 How to get vitamin D from food?45:00 How and when to get your vitamin D status assessed 47:30 Omega-3 intake 50:00 Interesting omega-3 findings 51:30 Adult men - the forgotten group? 53:10 Teenagers - 15 inadequate nutrients! 54:00 Findings in females 19-45 years 56:20 How to know if you are not getting enough of certain vitamins and minerals?60:00 How does exercise impact vitamin and mineral needs?62:45 How can someone maintain healthy eating habits while still enjoying what they eat? 65:45 How can your research findings be used in the real world?  One-liners you don’t want to miss: “We know that calcium intake is low, what we didn’t know was just how low and how severe that inadequacy was.”  “It looks like higher intakes of vitamin C are really beneficial of 150-200mg/day. It doesn’t sound very much when you can go and buy vitamin C tablets which are 1000mg/day but the key with that is our body can’t absorb all of that at one time.” “People are only over-consuming in nutrients of concern.” “How we live, where we live, our lifestyles, our overall diet composition, how much exercise we are doing; all of these things really effect magnesium intake.”  “Your body is not going to run out of calcium in terms of your blood levels. But what happens is when you don’t have enough calcium in your blood it will start to leach out of your bones.”  “Vitamin D intake will help to decrease fracture risk. We need sufficient vitamin D to make sure we can adequately absorb calcium.”  “Iron, vitamin D, calcium and the omega-3s, if you are exercising and very active. If you are concerned about priority nutrients those are the four. The other one that is also highlighted is selenium, that’s because it has antioxidant function. Selenium and vitamin E also work together, so getting both of these in.” Reference Starck CS, Cassettari T, Beckett E, Marshall S, Fayet-Moore F. Priority nutrients to address malnutrition and diet-related diseases in Australia and New Zealand. Front Nutr. 2024 Mar 13;11:1370550. doi: 10.3389/fnut.2024.1370550.

    The 10 easiest ways to include legumes in your diet

    It's Pulses Week and this year I’ve teamed up with The Grains & Legumes Nutrition Council and we are keeping it easy!  We cover:  10 easiest ways to include legumes (beans/peas) in your diet FREE e-RECIPE BOOK One-liners you don’t want to miss: “Legumes support a healthy gut, help improve overall health, are full of key nutrients like protein and fibre and reduce risk of chronic disease.” “1 cup of cooked peas provides 8g of protein and because it is a plant protein, also provides fibre, about 8g. In terms of micronutrients, just to name a few - peas contain iron, zinc, vitamin C and vitamin K. “ “Now it doesn’t get much easier than canned legumes. Crack the can, drain the liquid and you have your beans. One of the easiest ones for forming a dish is the four bean mix can. I mean, who doesn’t love a 2 for 1 let alone a 4 for 1.” Support the show

    How healthy is sushi?

    Sushi is a quick, easy, better-for-you takeaway option that is popular by many. It’s time to dig into the nutrition alongside Jiwi chef and 4th place getter on NZ Masterchef, Hana Kirk. We cover:  Behind the scenes Masterchef What is sushi? Differences between sushi in NZ/Aus vs Japan Changing landscape of sushi and diet in Japan What is actually in sushi Sugar in sushi rice Black/brown rice vs white rice How to make sushi Homemade sushi and how long it lasts How much soy sauce to have with sushi  One-liners you don’t want to miss: “Teriyaki chicken sushi is not a thing in Japan.” “Do a temaki sushi (cone-shaped sushi) at parties. It’s so much fun and it’s way quicker and you get to choose your filling for each bite you have which makes it really fun and interactive.” “Traditionally, when you have the traditional sashimi, you only use a little bit of the soy sauce. And you don’t put the soy sauce on the sushi, you are meant to dip your sushi in the soy sauce on a little plate. Even pouring it on in Japan is a bit like…what are you doing…” Support the show
