Hate vegetables? You might have super-taster genes!

Do you hate vegetables? You’re not alone. About 20% of the population are “super-tasters”. Super-tasters have more taste buds than other people and are super sensitive to the bitter compounds found in some food and drinks, even at low concentrations. If you have inherited super-taster genes then cruciferous vegetables (flower vegetables in the cabbage family) like bok choy, broccoli, Brussels sprouts, cauliflower, radish, swede, turnip, and watercress will taste disgusting.

We know too much sugar is bad for us, but do different sugars have different health effects

Our recent article published in the Medical Journal of Australia found that Australian and European soft drinks contained higher concentrations of glucose, and less fructose, than soft drinks in the United States. The total glucose concentration of Australian soft drinks was on average 22% higher than in US formulations.

Health Check: can chopping your vegetables boost their nutrients?

Health Check: can chopping your vegetables boost their nutrients?

We all know eating vegetables is a good way to improve health. And for many years the focus has been on just eating more vegetables, be it fresh, frozen or tinned.

But what if there was a quicker and easier way to get more benefit from our vegetables? Can the way we prepare vegetables boost their nutrition? Does tearing or chopping your lettuce makes any difference? And if we chop, does it matter what type of knife we use?

It’s a myth that humans’ sense of smell is inferior to that of other animals – here’s why

Conventional wisdom has it that humans have a poorer sense of smell than most other animals. Sure, we can smell – most of us appreciate the aroma of our morning coffee or a delightful fragrance, and we’re able to detect burning toast or a gas leak. But we have nonetheless long been thought to be relative weaklings in the animal kingdom’s league of olfactory excellence, which puts dogs and rodents near the top.

Food as medicine: your brain really does want you to eat more veggies

As well as our physical health, the quality of our diet matters for our mental and brain health. Observational studies across countries, cultures and age groups show that better-quality diets – those high in vegetables, fruits, other plant foods (such as nuts and legumes), as well as good-quality proteins (such as fish and lean meat) – are consistently associated with reduced depression.

The science of laughter – and why it also has a dark side

When you hear someone laugh behind you, you probably picture them on the phone or with a friend – smiling and experiencing a warm, fuzzy feeling inside. Chances are just the sound of the laughter could make you smile or even laugh along. But imagine that the person laughing is just walking around alone in the street, or sitting behind you at a funeral. Suddenly, it doesn’t seem so inviting.

Why deaf people can have accents, too

Most people have probably encountered someone who appears to use lip-reading to overcome a hearing difficulty. But it is not as simple as that. Speech is “bimodal”, in that we use both sounds and facial movements and gestures to communicate, so deaf or seriously hearing-impaired people often use lip-reading or “speech-reading” – watching facial movement, body language and mannerisms – to understand what people are saying to them.

The brain: a radical rethink is needed to understand it

Understanding the human brain is arguably the greatest challenge of modern science. The leading approach for most of the past 200 years has been to link its functions to different brain regions or even individual neurons (brain cells). But recent research increasingly suggests that we may be taking completely the wrong path if we are to ever understand the human mind.
