Our skin can turn 7-dehydrocholesterol into vitamin D with just a little help from sunshine. With the winter pall setting in, you're probably not getting much sun, but no biggie - you can also get vitamin D from your food. You may be wondering though - how much sunshine is enough?

In Australia’s most recent nutrition survey, 29 per cent of people reported having taken at least one dietary supplement. However, a new review of 180 studies found little or no protective effects from taking dietary supplements, and actually found some harm.
We all need vitamins, but that doesn't mean you need to take a vitamin. This week, science gave us another brick for the giant "vitamin pills are useless for most of us" sign that's been under construction for a while. (It's a metaphor, but I imagine it as something like the Hollywood sign, except nobody looks at it because they're all busy shopping for vitamins in the valley below.)
This is the season when we send our kids off to school with shiny new backpacks, and every year, they bring home the same thing: The first round of back-to-school colds. In our house, with a two-year-old intent on drooling on everyone he touches and a six-year-old still perfecting her personal hygiene practices, pathogens are passed out like hugs, and it's only a matter of time before the whole family is sick.
Today's kids have thousands of apps and educational programmes that tell them how to eat healthily. When I was growing up, we learned the Food Pyramid. We categorised grub into four food groups and that was pretty much it. But look back a bit farther, and dietary advice gets a little weirder: in the early 1950s, there were seven food groups, and one was just for butter.
Gwyneth Paltrow used to be best known as an actress, but in the last decade she's built an even bigger reputation as a health guru. Her newsletter venture, Goop, peddles an enviable lifestyle -- travel, fashion, anything that looks gorgeous in photographs -- but with a central message of living a clean, healthy life.
There are many brands of kids' “vitamin gummies” on the market. They are promoted as deliciously flavoured and a great way for growing bodies (and fussy eaters) to get the nutrients they need. In our opinion, these products are unhealthy, poorly regulated and exploitative. Their high sugar content may appeal to young children, but they’re not a good introduction to a healthy diet.
You most certainly know someone taking fish oil pills - those fishy, translucent gold capsules - for their purported heart benefits. But evidence continues to mount that fish oil might be snake oil.
At the very least, it doesn't pack nearly the punch we once thought. Instead, it's probably just worth eating actual fish, which is loaded with plenty of healthy vitamins and minerals.
According to the World Health Organisation, iron deficiency – a condition where your body doesn’t have enough of the mineral iron – is a global public health problem of “epidemic proportions”. This week Australian Prescriber published an update on the problem of iron deficiency in Australia.
Around 12-15% of women who are pregnant or of reproductive age and 8% of preschool children in Australia are estimated to have iron deficiency anaemia. Iron deficiency without clinical anaemia is even more widespread. Luckily, better dietary choices can be part of the solution. Here's what you need to know.
Iron deficiency is the world's most common nutritional disorder. As many as two billion people have anaemia, mainly from not getting enough iron in their diet, according to the World Health Organisation (WHO). So, other than eating more iron-rich foods, another good way to increase iron intake is to cook foods in a cast iron pan.
We all swear by something that we know probably doesn't work. Maybe it's vitamin C when everyone at work has a cold, or #bootea while we diet, or compression socks while we run. "Even if it doesn't work, what's the harm?" we tell ourselves. The truth is, it's not harmless, and we're only fooling ourselves.
There's nothing quite like waking up after an incredibly lucid dream. Whether you were flying through the heavens, starring in your own action movie or making out with your secret crush, the lingering memory can put a spring in your step for the rest of the day. Unfortunately, most dreams are meandering, colourless and entirely forgettable -- which is why you need these hallucinatory dream hacks.
Dear Lifehacker, I want to eat a healthy, balanced diet, but does that actually include a multivitamin? If I eat well, shouldn't I get the nutrients I need by default? I assume a multivitamin won't hurt me, but I don't want to bother if it isn't necessary. So should I take a daily multivitamin or not? Thanks, Vexed By Vitamins
Australia's complementary and alternative medicine (CAM) industry is worth about A$4 billion annually. Around two thirds of Australians use CAM -- which includes therapies such as chiropractic and naturopathy, traditional Chinese medicine, vitamins, minerals, nutritional supplements, as well as homoeopathic and aromatherapy products -- and there appears to be no sign of this declining. In many cases, the evidence for CAMs having significant beneficial effects is scant. And recent studies have even found that some supplements can be harmful.
We've pointed out many times that the scientific evidence for the benefits of taking multivitamins is slim and that a healthy diet should get you the same benefits. That said, we were interested to note one recent study which does suggest that taking a daily multivitamin had a modest but measurable correlation with lower cancer rates.
