..and you trust Twix? by going to THEIR website
Funny how you never provided a source to your claim that a Twix candy bar has the equivalent fat of 12 bacon strips. You didn't even note the size of the slices, either where fat content can differ. But I did.
Analyzing on the nutritional amount laboratories must follow appropriate methods using the Association of Analytical Chemists (AOAC) in Official Methods of Analysis of the AOAC International, 18th edition (2005).
So, where did this "12 strip of bacon" claim of yours came from? Where is your source?
60 grams of fat from 12 strips of bacon is a lot of fat. But if you took the time to look at how much two Twix cookies weigh it's 50 grams. That won't work with the 60 grams of fat. Even with medium uncooked strips of bacon it'd be 40 grams of fat which would make up 80% of the cookies weight. That won't work. Thin slice would be 25 grams which would be 50% of the cookies' total weight but this candy is not a solid chocolate bar.
Using 12 cooked bacon slice at 3.75 grams of fat per slice would equal to about 45 grams of fat. Using your claim would mean that 90% of the calories from the two cookies (one Twix package) would come from fat. In short, your own claim gets shot down thusly.
Natural cacao beans contain between 50 to 58 percent fat by weight so you can't get any more fat out of chocolate than 58%. Dark chocolate contains 65 percent to 85 percent cacao. Fat content gets lighter as more sugar gets added to lessen the bitterness of natural chocolate.
18% of caramel by weight contains fat. So, that doesn't help your claim.
The cookie wafers or bars fat content is assuredly less than the chocolate itself.
One gram of fat is 9 calories. Fat is fat when it comes to calories amount which is still 9 calories per gram of fat. There are 250 calories for the two cookies. 110 calories are from fat or 12.2 grams of fat. 110/250 = 44% of the cookies' calories come from fat. Some put the fat calories at 120/280 which brings it down to 42% of the calories come from fat.
In short, your claim doesn't make sense.
