What is GMP?

You’ve likely seen ‘GMP’ on a Phenyketonuria (PKU) or Tyrosinemia formula label or heard about it through your dietitian. But what exactly is it and why is it getting so popular?GMP can be used as a protein source for PKU and Tyrosinemia formulas. GMP, short for glycomacropeptide, is a peptide – a type of short protein. Peptides typically consist of shorter chains of amino acids, whereas true proteins are larger and more complex structures.

GMP is a byproduct of the cheesemaking process. Cheese is made from milk and contains intact protein. Milk consists of two types of proteins: casein and whey. During the cheese making process, the whey is separated from the casein; the casein part is what is used for cheese, the whey part is used for other purposes. GMP is found in the whey portion and must be filtered out to be used as an ingredient in formulas.

Contrary to other proteins, pure GMP does not contain phenylalanine (PHE), tyrosine (TYR) and a couple of other amino acids. That’s why it is a suitable protein source for PKU and Tyrosinemia formulas. However, through the process of isolating GMP from the whey part of the milk, some very small amounts of PHE and TYR cannot be filtered from the actual GMP and are part of the GMP ingredient used in PKU and Tyrosinemia formulas.

GMP by itself lacks certain amino acids that are important for growth and development. These amino acids must be added to the formulas so that PKU and TYR formulas are appropriate for individuals with PKU or Tyrosinemia. That’s why you see GMP and free amino acids listed as ingredients on your PKU and Tyrosinemia formula label.

You may have noticed slight variations in the PHE content when comparing GMP formulas (for example, between 10‐18 mg PHE per 10 g protein equivalent). Healthcare professionals have told us, that the differences are so small that they are clinically not relevant, and studies support this. This means that if a GMP‐based product is appropriate for someone with PKU or Tyrosinemia, the slight differences in PHE content are not important.

GMP is still a growing concept, but several studies support that GMP‐based products are safe and appropriate for most individuals with PKU or Tyrosinemia. GMP‐based products have a milder taste, and that milder taste is often preferred over amino acid‐based products. Finding a formula you or your child like is very important as that can certainly help with diet adherence. In addition, a small number of studies also report that patients feel fuller when consuming a GMP‐based formula.

A small number of clinical studies are also looking into other benefits of GMP‐based products in metabolics. However, the results of these studies are inconclusive. More research is needed to provide definite answers.

For some people with PKU or Tyrosinemia, the amount of PHE in GMP‐based formulas may be too high. Rest assured that formulas that are based 100% on amino acids (with no GMP) provide you or your child with all the nutrients needed for proper growth and development, including important vitamins and minerals for bone health. But of course, your dietitian can advise you on which formula is best for you or your child.

10 Low Protein Lunch Tips for Back-to-School

Back to School: Attention Moms & Dads

Written in collaboration with Katie Maguire, PKU Adult and 2nd grade school teacher

I don’t know about you, but it was stressful for my parents sending me off to school in September knowing that I would be making many food choices on my own without them present.

ALL children should be able to make healthy food choices. Children with PKU, MSUD, TYR or other metabolic disorders are no different.

Learning healthy choices can begin at a young age when you grocery shop and prep food in the kitchen together.

10 Low Protein Lunch Tips for Back-to-School

 

  • Pack lunch in fun, creative containers in all different sizes.

  • Use an insulated lunch tote with ice packs to keep food and formula cool.

  • Make lunch colorful with a small amount of different veggies, such as baby carrots, cherry tomatoes, cucumbers, yellow peppers, etc.

  • Prepare, weigh and measure food ahead of time to speed up mornings.

  • Give your child a low protein “surprise” snack like homemade cookies or a cupcake.

  • Write a special ‘good job’ note or include a sticker 2-3 times a week.

  • Send formula in a fun re-usable drink container or sports bottle.

  • Plan ahead with a 5-day menu to ease grocery shopping and food prep.

  • Try a ready-to-drink formula if unable to mix formula at school.

  • Involve your child in shopping, prepping and weighing their own lunch.

Making the Most of Your Meal

Satisfaction from food or a meal is something everyone wants. Although many foods may be restricted or limited on a low protein diet, you do not have to compromise taste. Selecting the  foods you eat involves a variety of factors. We choose foods based on taste and smell, in addition to texture, sight and culture.

To make the most of your meal, begin by identifying what you crave, like spicy, sweet, crunchy or salty. This will make your meal more satisfying.Here are some tips to help you make the most of your meal.

  • Spicy: Add seasonings that can add a kick. For example, add cracked pepper, crushed red pepper or hot sauce to steamed vegetables to give a familiar item a new twist.

  • Sweet & Tangy:  Satisfy your sweet and tangy craving with grilled pineapple topped with BBQ sauce on a low protein bun. You can also add mandarin oranges and Italian dressing to a garden salad for added flavor and tang.

  • Crunchy: With a little creativity you can add a snap to any dish. Make your own salad iStock_000015639017Mediumcroutons with low protein bread. Season them in a variety of ways by using garlic powder, cayenne pepper or Italian herbs depending on your personal desire for savory or spice. Another great way to add crunch is to include raw vegetables, like cucumbers or carrots slices to a salad or sandwich.

  • Salty: Salt is among the most popular taste craving. Although highly desired, salt is an ingredient to be used in moderation. A little bit goes a long way. To satisfy your craving for salt, try slicing fresh potatoes very thin and sprinkling with garlic and a touch of sea salt. Bake them until crisp for a satisfying addition to your meal or snack.  

  • Smooth and Creamy: Create your own creamy low protein dip with your favorite seasonings for a flavorful way to enjoy Low Protein Crackers or fresh cut vegetables. You can also include a sweet treat at the end of your meal to help satisfy your need for something smooth and creamy.
