Fat Comparison: Olestra And The Human Body

224 Words1 Pages
Olestra, known under the brand name Olean is a fat substitute. It can be found in snack foods like potato chips, corn chips, cheese puffs, crackers, doughnuts, French fries, fried chicken, margarines and cheeses and many more. It is a sugar-based compound that is not digested or absorbed by the human body. Normal fats are three fatty acids bonded to a glycerol molecule (Martini el al., 2018, p.50). Olestra, however, uses a sucrose (table sugar) molecule joined at esters bonds to form eight fatty acids, instead. The olestra molecule is much larger than natural fats and cannot be broken down by normal digestive processes neither in the small not in the large intestine. It cannot be absorbed across the intestinal wall nor can it be metabolized
