Recently a series of 'healthy' fruit cups came into our house to be packed in lunches. These healthy snacks feature cut fruit packed in water with no sugar added.

The idea of packing fruit in water without sugar sounds great, but the reality is a different matter. During the design and testing of this product those responsible for it clearly forgot an important lesson in high school science.

Diffusion: The transport of molecules from an area of higher concentration to an area of lower concentration by random molecular motion.

This is what sets these fruit cups apart from everything else. While the fruit and water start out normally, during the time spent on the shelf, the sugar molecules randomly make their way out of the fruit into the water. This also happens with the flavour of the fruit.

The net result is some lightly sweetened water with fruit flavours and some nearly tasteless fruit. The fruit manages to maintain its original texture, which is rather remarkable considering the harsh flavour transition it has just undertook.

What we have here is a line of products that will taste nothing like you expect them to, and have caused feelings of nausea and hunger on my walk home. As good as eating healthy is, trust me, this isn't worth it.
