    People with this condition must avoid all milk, milk-containing products (including dry milk), and other foods that contain galactose for life. It is essential to read product labels and be an informed consumer.

    Infants can be fed with:

    • Soy formula
    • Meat-based formula or Nutramigen (a protein hydrolysate formula)

    Calcium supplements are recommended.

    • Death (if there is galactose in the diet)
    • Delayed speech development
    • Irregular menstrual periods, reduced function of ovaries leading to ovarian failure
