| 2/3/26 | ![]() Should we all be taking fish oil? | How many times a week are you eating fish?

| 1/20/26 | ![]() Is retirement bad for you? | Last year Norman made the shocking statement that people shouldn’t retire because it’ll be bad for their brains.After an influx of requests, we’ve looked at the evidence not only when it comes to brain health, but heart health, metabolic health and mental wellbeing.Norman and Tegan unpack the complex story of what happens to your brain and body when you retire – depending on the job you had.References:How Retirement Was Invented: The earliest schemes for financial support in old age were pegged to life expectancy Towards higher retirement incomes for Australians: a history of the Australian retirement income system since Federation Impact of retirement transition on health, well-being and health behaviours: critical insights from an overview of reviews Effect of retirement on cognitive function: the Whitehall II cohort study Retirement or no Retirement?

Or are the two inherently intertwined?Norman and Tegan try to untangle the untangleable, pitting diet and exercise against one another in different arenas.

| 1/6/26 | ![]() Why you don't need to avoid seed oils | It can be hard to keep up with food fads and diet trends (and spoiler: you don’t need to).But an intriguing assumption that has gained traction recently is that seed oils – think canola, sunflower, grapeseed – are terrible for you.Norman and Tegan unpack how that assumption has spread, and whether there’s any solid evidence to back it up.References:Biomarkers of Dietary Omega-6 Fatty Acids and Incident Cardiovascular Disease and MortalitySerum n-6 polyunsaturated fatty acids and risk of death: the Kuopio Ischaemic Heart Disease Risk Factor StudyOmega-6 fats to prevent and treat heart and circulatory diseasesPolyunsaturated fatty acids intake and risk of all-cause mortality, cardiovascular disease, breast cancer, mental health, and type 2 diabetes: A systematic review and meta-analysis of prospective cohort studiesPerspective on the health effects of unsaturated fatty acids and commonly consumed plant oils high in unsaturated fatIf you’re worried about inflammation, stop stressing about seed oils and focus on the basics | — | ||||||

| 12/23/25 | ![]() Why do some people pee more often? | Do you find yourself complaining that you've got a small bladder, as you run to the toilet for the third time in an hour?There are many reasons a person might pee more than others, including some scary medical conditions.

| 12/16/25 | ![]() Sunscreen spectacular: UV protection, SPF drama, endocrine disruptors | There have been many discussions this year about sunscreen, its effectiveness and its ingredients.While there are some unknowns, what we’re sure of is sunscreen’s ability to protect us from the sun’s ageing and cancer-causing rays.Norman and Tegan slip, slop, slap some questions about sunscreen: SPF scandal, endocrine disruptors and vitamin D concerns.References:How does sunscreen work? - Cancer Council Sunscreen: a brief walk through historyWe tested the SPF claims of 20 sunscreens. 16 failed - CHOICETGA statement on CHOICE SPF sunscreen findings Safety Review of Seven Active Sunscreen Ingredients – July 2025 Daily sunscreen application and betacarotene supplementation in prevention of basal-cell and squamous-cell carcinomas of the skin: a randomised controlled trialMineral vs chemical sunscreens Can your sunscreen expire?

| 11/18/25 | ![]() Should you aim for an alkaline lifestyle? | Humans are slightly alkaline – your blood should be a pH between 7.35 to 7.45.
