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• 9:45 Are the Nutrient Reference Values (NRVs) outdated?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 research
• 31:30 Vitamin D deficiency in Aus/NZ
• 32:30 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.”

• 7:15 Description of the evidence-base on the effect of the menstrual cycle phase on energy intake
• 9:10 Phases of the menstrual cycle
• 11:05 The effect of the menstrual cycle phase on energy intake

• 17:00 Any other interesting pieces of research since the 2023 narrative review
• 18:35 What else could be driving the increase/decrease of energy across the menstrual cycle?
• 19:10 Effect of the menstrual cycle phase on exercise performance and physiology

• 32:00 Training across the menstrual cycle
• 35:00 How will this field of research progress over the next 5, 10, 15, 20 years!

One-liners you don’t want to miss:

"That second half I guess you could say, of the menstrual cycle after ovulation, energy intake is higher and there seems to be a little bit more of a consistent pattern, that energy intakes higher in that luteal phase than in the follicular phase of the menstrual cycle.”

“Try and have the unprocessed foods - fruits and vegetables, so basically increasing your micronutrient intake (your minerals and vitamins) could help alleviate some of those symptoms that might get around menstruation.”

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.”

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

• How to make sushi
• Homemade sushi and how long it lasts

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…”
