My favourite junk food snack is a kit Kat bar. I like the chocolaty flavor on the outside and the crispy wafer it the inside. I also like the ways you can eat a kit Kat bar. You can either break it up and eat the whole thing at once. Some additives in a kit Kat bar are polyglycerol polyrincoleate (PGPR) and soy lecithin. PGPR and an emulsifier that reduces the need for the amount of coca butter and slows down the frictions of particles in the chocolate. Soy Lecithin is also a emulsifier but some believe it carries potential health dangers. The ingredients in a kit Kat bar are Milk chocolate (sugar, modified milk ingredients, cocoa butter, cocoa mass, whey powder, lactose, soy lecithin, polyglycerol polyricnoleate, natural flavor), wheat flour, sugar, modified palm oil, cocoa, sodium bicarbonate, soya lecithin, yeast, Natural Flavor). when I’m at a store I’ll will usually get on bar or if I’m really craving so e chocolate I will get the package with two kit Kat bars. Their are 510 calories in one serving (one whole bar) of a kit Kat bar. This foods isn’t the healthiest because it has a lot of calories in just one serving and it also has 26g of fat in it as well.
