slows the pancreas's release of lipase enzyme.
consists of tight protein-binding molecules that replace the fat molecules usually present in potato chips.
contains a fat-like substance that the body's enzymes can't break down and therefore cannot be absorbed.
is first subjected to radiation exposure to desaturate the bonds within the fat molecules, which reduces the kcalorie content.

Unfortunately, I was not able to open the attachment; therefore, I was unable to answer one question. Otherwise, I have provided the answers as well as a brief explanation for the remaining questions.

1.) There are three main type of micronutrients: proteins, fats, and carbohydrates. These are nutrients that provide energy and calories. Therefore, the answer is Protein.

2) The answer is 755 kilocalories which tells you the amount of energy stored in foods. A kcalorie is equal to 1000 calories. 20g fat x9= 180, (25g x4) + (110g carbohydrates x4) = 540 When food contains alcohol, add seven kilocalories per gram of alcohol (7g x 5)= 35.
180+ 540+ 35= 755

3) The Recommended Dietary Allowances because they represent the average daily amount of a nutrient considered adequate to meet the known nutrient needs of practically all healthy people.

4.) Historical information, ...
