Galactose is a natural sugar that is found at high levels in some foods and at lower or very low levels in
other foods. Galactose is also made at low levels by the human body.

Galactose is present at very high levels in milk. This includes human breast milk, cow’s milk, and other
natural forms of milk. The galactose in milk comes from lactose, or milk sugar, which is broken down by
normal digestion to release glucose and galactose. Galactose is also found at high levels in most dairy
products, including soft cheeses, ice cream, cottage cheese, etc.

Galactose is stable to heating; it is not broken down by boiling or normal cooking processes. Galactose is
not present at high levels in milk substitutes such as soy formula or soy milk, almond milk, or rice milk.
