Unibic Butter Cookies
Unibic's butter cookie, and the outlier of this entire file: its declaration puts butter at 20% - forty times the 0.5% Britannia Good Day Butter declares - and replaces sugar with maltitol and a sweetener. The pack panel gives 490 kcal, 6.3 g protein, 65 g carbohydrate of which just 0.5 g sugars, and 22.8 g fat of which 14.6 g saturated, with 85 mg sodium per 100 g. At 0.5 g sugar it has the lowest sugar of any cookie here by two orders of magnitude, and the highest saturated fat. Those two facts are the same fact, and both belong on the comparison page.
