Your mums are probably really good people. We’re sure they’re your best friend and made your ascension into adulthood possible but here’s a truth bomb: unless they’re actually doctors, they probably told you a bunch of lies growing up.

And we’re not talking about the white lies like the existence of Santa Claus or Mummy and Daddy splitting up not being your fault, we mean those lies about good health that your mum pedalled back in the day.

Unfortunately the media loves sensationalism and it becomes hard to separate the quagmire of hysteria for the aquifer of fact, especially when it involves the state of health of our nation. Here are five medical myths we all believe debunked by Stanford medical professor, David Chan.

1. The Salt Myth

The low salt diet is “one of the most poorly documented recommendations that the US department of agriculture promoted”. In short, the link between heart disease and above-average salt intake is pretty tenuous to say the least.

2. The Milk Myth

Remember when your parents transitioned you away from whole milk (the blue one)? Well, they probably didn’t need to. Children who drink whole milk instead of skimmed milk have lower obesity levels because they are less hungry all the time and therefore eat less.

3 . The Frozen Myth

Iceland actually aren’t the crooks we thought they were. It turns out that frozen fruit and veg isn’t less healthy than fresh. Prolonged shipping and shelf life at the supermarkets causes fresh produce to degrade. Great news for dieters on a budget!

4. The Carbs Myth

The food pyramid of the 1970s instructed western food eaters to eat more carbs which hiked up hunger and peaked blood sugars accordingly because of increased insulin levels. For some reason everyone was confused when we all got diabetes. Saturated fats lower these hunger pangs and reduce obesity when consumed as part of a balanced diet.

5. The Multi-Vitamin Myth

An alarming amount of studies find that taking multi-vitamins does not improve overall health unless you’re taking them for specific ailments like macular degeneration or any type of deficiency. “Most vitamin studies show a higher cancer rate, not lower”. Yikes.
