    MSUD Is A Rare Disease

    MSUD is a rare disease, affecting an estimated 1 in 185,000 infants worldwide. The condition gets its name from the distinctive sweet odor of urine and earwax in affected infants. If untreated, MSUD can lead to developmental delays, seizures, coma, and death. A strict diet and careful medical monitoring is essential throughout the lifespan. Foods that have high protein content (most meats, dairy and fish products) must be avoided.

  • Treatment


    Treatment of children with MSUD centers around a carefully controlled diet, the mainstay of which is a “medical food” or formula. Natural foods focus on fruits, and many vegetables. Food that are rich in protein, such as meats, dairy products, and fish are highly restricted.
