They taste great, but the fat that provides the lovely texture in some of these foods can clog up your arteries and can cause heart disease.

But now you can pig out on fatty cold meats and stay healthy.

Until recently, the by-product from cheese-making, called whey, was fed to pigs, even though food technologists knew it was as nutritious as the cheese.

Then it was discovered that, with treatment, this whey just happens to look and feel like the little bits of fat in cold meats.

So CSIRO scientists decided to try and substitute the fat in the cold meats with the healthy, fat free, whey product.

"The part of the cheese whey that we use to make the fat replacer is the protein. What we discovered was this protein can form a gel which although it contains 90 per cent water, actually has the appearance and texture of solid fat."

Cold meats like these are enormously popular around the world, and it's the little bits of fat that make them look and taste right. So if they can be replaced with this high protein substitute made from whey, that looks and tastes the same, it could have a huge overseas market.

So far the strasburg is selling like cold meat, but a new product on the market is literally sell like hot dogs.

A bit of lateral thinking from science making taste healthy.
