Hello!

My name is Lauren Roberts and I'm your new online health reporter, taking the reins of the weekly health newsletter.

First up, let's talk about multivitamins. This week a study found taking a daily supplement slowed two markers of biological aging.

But what does that mean?

Researchers analysed something called epigenetic clocks — tools which measure tiny changes our DNA — finding people who took daily vitamins had slightly slower aging in two out of the five clocks.

Before you rush to stock up on supplements, let's take a look at the fine print.

The science behind epigenetic clocks is fascinating, but it's not really clear what exactly they measure and how this may, or may not, impact anyone's life span.

Experts say healthy people who eat a varied diet, simply don't need a daily vitamin. 

The best advice for those keen to look after their bodies? Eat well, exercise, reduce stress and avoid alcohol.

And speaking of things to safeguard your health: Experts are urging you to roll up your sleeves and get your flu jab when it becomes available in April.

The advice comes as a new, fast-moving strain of influenza dubbed "Super-K" is circulating in Australia.

But the good news about Super-K? Vaccine experts factored it in when they designed this year's flu jab, and say it will likely provide pretty good coverage.

And this week on the Health Report: Are Aussie schoolchildren eating too much salt?

The short answer is yes.

Dr Norman Swan and Dr Preeya Alexander discuss a study where nearly three quarters of the kids exceed the maximum limit for sodium for good health.

Yikes. Tune into the episode to hear some tips and tricks to reduce your family's salt intake and why it matters.

A study published this week claims taking a daily multivitamin may help slow markers of biological aging. But does the evidence match the headlines?

Experts say they are feeling "nervous" as Australia approaches this year's flu season, with a new, fast-moving strain of influenza dubbed "Super-K" circulating as vaccine uptake dwindles.

Outdated medical devices are being used to perform a common obstetrics procedure on Australian women that can cause a condition known as Asherman's syndrome.

The way ADHD is diagnosed and managed is changing across the country. Here's the reason for the change and how it will work in each state and territory.

The study — which surveyed almost 4,000 south-east Queensland children — found average mole count plummeted from 87 in 1992 to 46 in 2016 — a 47 per cent reduction.

The number of GP home visits has declined by 85 per cent in Australia over the past three decades, which doctors say is driving vulnerable people into residential care and hospital prematurely.
