What does it mean?
Per serving, each bar has just under 100 calories, which is a great snack size. Per 100g it is low in saturated fat (looking for less then 1.5g/100g), it is high fibre and low sodium.
Although the product is high is total fat, we can see in the ingredients list that some of this is coming from sunflower seeds. It is high in sugar, which can be identified in the ingredients list as 'Rice Bran Syrup,' but given the other positive aspects of this product this could be a better choice them other snack bars for an 'extra' to include in the lunchbox.
I can't comment on the taste as I didn't actually buy them - simply because there are better things that could go in a lunchbox.
