Wake up and smell the fat

We often think of the human nose as not being particularly sensitive, at least compared to our canine companions. However, this is not the case and many people can distinguish between hundreds if not thousands of odors at very low concentrations. Moreover, scientists at the Monell Center have shown that we can detect dietary fat in our food from smell alone. The findings by cognitive neuroscientist Johan Lundström and his colleagues identifies one of the first sensory qualities that helps us assess food before we put it in our mouths. The research could point the way to improving the perception of reduced-fat products aimed at those hoping to reduce their total daily calorie intake.
