What is Olestra?
Olestra is a fat substitute created by chemically altering the structure of fats to prevent their absorption in the digestive tract. Approved by the FDA in 1996, it is used primarily in snack foods like chips and crackers to lower their calorie content. As Olestra passes through the body without being absorbed, it can provide the sensory qualities of fat without contributing calories or fat to the diet.

Why People Avoid Olestra
People may avoid Olestra because it can cause digestive discomfort, including abdominal cramping and loose stools. Additionally, because it is not absorbed, it can also inhibit the absorption of fat-soluble vitamins (A, D, E, and K) and other nutrients, potentially leading to deficiencies if consumed in large amounts. Some individuals prefer to avoid synthetic additives altogether.
