Is it just me, or are diet aids getting more and more weird?
We've had "Le Whiff" - chocolate you inhale. And now, the latest upcoming craze is crystals.
Tiny crystals that you sprinkle on your food. Doesn't sound too appetising, does it?
The crystals, called Sensa granules, enhance the smell of food, meaning that it tastes better (smell can count for up to 90% of what we experience as the "taste" of a food). They were developed by the neurologist Dr Alan Hirsch (from the Smell and Taste Treatment and Research Foundation in Chicago) back in 2008.
The Sensa website claims that:
By enhancing smell, Sensa Tastants were designed to help speed up the process and trigger your "I feel full" signal, so you eat less and feel more satisfied.
Sensa is currently on sale in America, costing $59 for a month's supply of the crystals. Other countries are expected to start selling them soon. Dieters are enticed by the promise they can carry on eating exactly what they already eat, without counting calories or exercising: the only change is that they sprinkle Sensa crystals on every meal and snack.
Some experts, however, are sceptical about the use of Sensa as a diet aid. Dominic Dwyer (a neuropsychologist at Cardiff University in the UK) said the idea behind Sensa was sound, but warned:
A mouthwatering smell from food can simply make us eat more. This stuff would have to be very carefully used.
What do you think? Would you pay $59 a month to sprinkle tiny crystals on your food? Would you be satisfied with less food if it tasted really good?
