Natural food products company Amish Naturals has launched a snack line of granola bars, including two fibre-rich varieties.

The new line, available nationwide next month, is a bid by the US company to enter into the US$1.8bn snack bar market.

"Our entry is an inherent extension of the Amish Naturals' Hi-Fiber Initiative and our mission to provide natural, premium food products that not only taste great, but are truly good for you," said president and CEO of Amish Naturals, David Skinner.

The granola bars will be available from next month in four flavours: dark chocolate, peanut butter, fibre-rich peanut butter and fibre-rich fruit and nut.
