Japanese pharmaceuticals group Kanebo said earlier this week that it has discovered that raspberry aroma can aid weight loss, and that as a result it will launch a new range of slimming products in May.

Shiseido, the cosmetics group recently announced plans to launch a new skin cream with certain fragrances including grapefruit which it alleges can aid weight loss.
