Just because you have a metabolic condition like phenylketonuria (PKU), maple syrup urine disease (MSUD), homocystinuria (HCU), or another inborn error of metabolism disorder doesn’t mean you can’t order restaurant food. Here are helpful tips for navigating common restaurant menus in the U.S. and Canada and finding low protein options that fit your diet.

Remember to always check a dish’s nutrient values and ingredients before ordering, as restaurants may vary in which ingredients they use. And always consult your metabolic healthcare team before making any changes to your diet or condition management.

For those with PKU, these menu tips are consolidated in our PKU Guides on Restaurants, available in English and Spanish on our Learning Center page. Print out and save for handy reference.
