Sun Chips can be considered better than regular potato chips, here's an oz by oz comparison
1 oz regular potato chips: 150 cal, 10g fat, 1g fiber
1 oz SunChips: 140 cal, 6g fat, 2g fiber
If you only had those two options, then yes, SunChips are better. But consider this:
1 oz baked potato crisps (Lays): 110 cal, 1.5g fat, 2g fiber
Much better here! They also have baked tortilla chips!
Hope that helps!
