What fat substitute got approved by the FDA?

The FDA approved the fat substitute called "olestra," which is a synthetic fat that adds flavor and texture to food without adding calories. Olestra is not absorbed by the body, allowing it to pass through the digestive system without contributing to fat intake. It is often used in snack foods, such as chips, to provide a lower-calorie option. However, its use has been associated with gastrointestinal side effects in some individuals.
