Can peptides keep you young and buff?

Unless you're in certain corners of the internet, you won't be aware of the peptide craze promising to grow your muscles and slow ageing. That's because your average GP won't be printing a prescription for these injectable drugs, like BPC-157 or melanotan. Norman and Tegan discuss why there's so much fan fare over unproven peptides with some potentially nasty side effects.

Can flossing benefit more than your teeth?

Your dentist might be nagging you to floss to avoid cavities, but does flossing have more to given than pearly whites? Interdental cleaning has been recommended for a while, but for many people it’s a habit hard to maintain. Norman and Tegan pick through the history of flossing, and whether it can improve your heart and brain health too. Terms and conditions of our World Science Festival Brisbane ticket giveaway!

Doing nothing: the benefits of boredom

With endless entertainment at your fingertips on your phone, how often do you really sit and do absolutely nothing? It turns out that even when you’re staring into the middle distance, your brain is firing away with activity.

Should we all be taking fish oil?

How many times a week are you eating fish? What about oily fish, like salmon and tuna? Our dietary guidelines recommend the regular consumption of fish to potentially reduce the risk of cardiovascular disease, dementia and even macular degeneration. Norman and Tegan dig into the oily history of fish, and whether supplements can have the same effect.

Should you wait to swim after eating?

It’s so common to tell kids to wait an hour after eating to swim that many of us never question it. But what are the actual consequences of jumping straight back in the pool after you’ve had your lunch? Norman and Tegan tackle whether this advice is grounded in evidence, and discuss what you should actually avoid.

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.

Diet vs exercise: which is more important?

A few weeks into the new year you might be reassessing your resolutions and wondering where to put your energy. Is it possible to choose between diet or exercise? Or are the two inherently intertwined? Norman and Tegan try to untangle the untangleable, pitting diet and exercise against one another in different arenas.

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.
