Prolonged journeys in space help inform research into frailty

Taking a bite out of the dangerous notion that food is medicine

Pseudoscience and quackery love the food-is-medicine philosophy because it helps them sell their nutritional supplements, diet books and therapy sessions

Taking a bite out of the dangerous notion that food is medicineHippocrates supposedly said, “Let food be thy medicine and medicine be thy food.” I disagree. Food is not medicine. I can hear people saying, “But Dylan, you have type 1 diabetes and a PhD in human nutritional sciences. Surely you of all people know that food has a powerful impact on health?” I do. But…

Three nutrition trends to stay away from

Cool the hype around genetics and health care

Fishing for seafood fraud report of questionable value

The methodology used by non-profit Oceana for its report lacks scientific rigour

Fishing for seafood fraud report of questionable valueOceana – an environmental NGO – is known for its splashy reports on fish and seafood fraud. Their cumulative assessment across several Canadian cities showed that 44 per cent of the fish samples assessed were falsely identified.

The red meat merry-go-round

The protein war isn’t about the amount of meat we should eat, but rather about how studies on nutrition should be interpreted. It's messy

The red meat merry-go-roundFor a few years, we’ve been force-fed the notion that red meat and processed meat products threaten our health. But the protein war between the livestock industry and plant-based supporters has taken an interesting twist. In 2015, the World Health Organization went as far as to say that processed meats were carcinogenic, adding them to…

Lab-grown coffee – agriculture’s rising revolutionBean-less coffee could hit the market as early as next year. Our summer was marked by key announcements from major food chains that have decided to switch to plant-based alternatives. Meat – particularly beef – was the target of companies like Beyond Meat and Impossible Foods, who claimed their plant-based products were more ecologically sound.…

The dark side of the Non-GMO Project

Suggesting that food products with the Non-GMO Project label are safer and more nutritious is simply misleading and rests on scrawny scientific evidence

The dark side of the Non-GMO ProjectMost consumers have seen Non-GMO logos on bread and other food products at the grocery store. But the verification program now faces criticism. The Non-GMO Project verified logo is now on over 50,000 food products in North America that bring in more than $30 billion in retail sales. The green leaves and orange butterfly logo first…
