Researchers at Australia's Deakin University have published a paper in the British Journal of Nutrition
showing evidence that human beings can taste fat -- that is, they can distinguish between two flavourless solutions in which one has more fat than the other.
I believe that this is true -- and that fat can offset bitterness the same way that sweet can. For example, raw cacao nibs mixed with cashew nuts taste sweet and chocolatey.
"We know that the human tongue can detect five tastes -- sweet, salty, sour, bitter and umami (a savoury, protein-rich taste contained in foods such as soy sauce and chicken stock)," Russell Keast, from Deakin University, said Monday.
Australian researchers say fat is 'sixth taste'
"Through our study we can conclude that humans have a sixth taste -- fat."
Researchers tested 30 people's ability to taste a range of fatty acids in otherwise plain solutions and found that all were able to determine the taste -- though some required higher concentrations than others.

Despite Trump’s denial of climate change the the ghastly attacks on climate science and mitigation in the new proposed budget, the Carbon Bubble — which overprices hydrocarbons and the industries that rely on them, as though we’ll be burning all of them with impunity — is about to pop.
South American polka dot tree frogs are pretty cool, but Julián Faivovich and Carlos Taboada found out they are even cooler when an ultraviolet flashlight is trained on them. They fluoresce. Many animals can see beyond the spectrum visible to humans, and these frogs adapted with this trait. From the abstract: Fluorescence, the absorption of […]
A small (51 men aged 24 +/- 3 years) study published in Neuron tasked experimental subjects with practicing the ancient Greek mnemonic technique of “memory palaces” and then scanned their brains with functional magnetic resonance imaging, comparing the scans to scans from competitive “memory athletes” and also measuring their performance on memorization tasks.
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
When Apple revealed the new MacBook in 2016, one of the biggest issues raised with the notebook’s new design (aside from ire over the slew of new adapters you’d inevitably have to buy) was the removal of one of its most beloved proprietary features, the magnetic charging cable. Thankfully, third-party peripheral makers have taken up […]
