Couldnt find on the website what is in those chips, but if you have a packet with you list them here, i dont proclaim to know alot about labelling, but have a little knowledge.
Incase you dont know - the order in which the ingredients appears on the label will determine if the weight of it is more than the next one listed.
IE, a can of baked beans i have in my cupboard lists the ingredients as follows and in this order.
Navy Beans
Water
Tomato Puree
Sugar
Modified Maize Starch
Salt
Flavours
Paprika Extract
So my point is sometimes you can see immediatley if a product is crap by the..... sugar for example. Many Chocolate products list Sugar as the first ingredient - you may as well go and buy a packet of sugar and eat it. The baked beans above obviously has the Navy beans as the most (which you would expect) and the water is the second most product in the can etc, etc..
