In a Canadian snack food industry packed with competing products, one of the old favourites has gained a new lease of life. Sales of beef jerky, the dried chewy meat snack, are growing by about 50% each year, and other meat snacks are also growing fast. Because it is high in protein and contains less fat and carbohydrates than most junk food, it is perceived as a healthier snack - despite being loaded with salt and preservatives, comments the Globe and Mail newspaper. The product is also extremely convenient, as it is handheld and generally requires no refrigeration.
