Free fructose

Definition

Simple sugar naturally occurring in fruits and honey or added as an additive in processed products as corn syrup rich in fructose.

How it works

Fructose is metabolized differently by the liver than glucose, but excessive consumption is linked to hepatic fat accumulation and metabolic disorders. Natural sources have fiber slowing absorption, while processed sources lack it. Fructose doesn't activate satiety hormones as effectively, leading to overconsumption.

Role

Provides rapid energy but may contribute to excessive liver fat accumulation.

Examples

• Sodas, commercial fruit juices, candies, industrial pastries, syrups, honey, fresh fruits

Recommendations

Drastically limit free fructose in processed foods and choose natural fruits with fiber.

Key takeaway

Natural fructose is beneficial when consumed with fruit fibers, but added free fructose in processed foods should be minimized.
