Low Protein Diet and children

Article 10 Following a low protein diet

Common Questions

How can I help my child stick to their diet?

As children grow, they become more aware of those around them and notice people’s differences. Children with PKU may feel tempted to eat foods that are too high in protein because they want to be like their friends or not seem different.

In addition, children with PKU may not feel different or unhealthy, so they may question the need to stick to their diet or treatment as they don’t “see” the benefits or effects of diet on their PKU. It is important for parents to be understanding of how children feel, but also be able to reinforce to their child that they are healthy because of following the treatment plan.

Tips to help your child

  • Try new PKU supplement options if supplement intake becomes an issue
  • Involve your child in the process of supplement preparation. i.e. becoming more comfortable with using scales and/or measuring utensils with your guidance
  • Send their PKU supplement to school in coloured sports bottles or try ready to drink supplements
  • Involve your child in meal planning – let them choose their own snacks or help you pack lunch
  • Keep PKU meals similar to family meals so that your child feels a part of and included in the foods his or her family eats
  • Keep low protein treats at school with your child’s teachers so that your child has something to eat while others are celebrating a birthday or other event
  • Include your child in protein counting throughout the day and encourage them to write foods in their diet record
  • Make your child aware of the importance of keeping their protein intake within their daily allowance

What if my child is still hungry at the end of the meal?

Like everyone, meals for children with PKU should be a balanced combination of protein, fats and carbohydrates. The PKU supplement supplies the majority of protein for many children and can help them to feel satisfied after a meal. Having PKU formula at the same time as their Phe allowance also helps to control levels and build body protein. If your child is still hungry at the end of a meal, offer them foods that are very low in protein or have no protein. Ask your dietitian for suitable recommendations and ideas.

What should I do if my child won’t drink their PKU supplement?

While some children may never have a problem taking their PKU supplement others will. Taking the supplement is not negotiable as it is essential for their health, however finding the best options for your child is worth the effort.

The PKU supplement is important for growth and development, balanced nutrition and to keep blood Phe in the acceptable range. Your child should drink all their PKU supplement prescribed, and this should be spread out over the day. Talk to your PKU team if your child does not drink the prescribed amount of PKU supplement. Some trouble-shooting tips for formula drinking are below.

Problem and Suggestion

  • Your child seems overwhelmed by the amount of supplement he or she needs to drink at each sitting.
    • Dividing the amount of supplement your child needs to drink into three to four smaller servings will make it easier to finish. This is also important for good Phe control and for the body to use this protein efficiently.
  • Your child does not want to drink their supplement during a meal.
    • Offer their supplement at the beginning of the mealtime when your child is hungry.
  • Your child does not have an appetite for their PKU supplement.
    • Cut back on other liquids or snacks and offer their supplement first, when they are hungry or thirsty.
  • Your child usually likes their PKU supplement but seems bored with it.
    • Freeze the supplement, then blend it and serve with a spoon. Serving it in a new cup can also be exciting. Explore different flavours or even use more than one supplement at a time for extra variety.
  • Your child doesn’t seem to like the taste of the PKU Supplement.
    • Talk to your PKU team about how to flavour the supplement or try other types or flavours.

Mealtime Tips

  • Keep positive
  • Your child should be allowed to form their own opinions about their diet. Explain to family and friends that they should keep a positive attitude towards your child’s diet. Keep trying new foods that are rejected as it may take a while for some children to accept new tastes.

Offer choice

As your child grows and becomes more independent, they may express their likes and dislikes more strongly. Allow your child to get more involved in small aspects of food preparation and making their own food choices.

Keep family meals similar

It can be difficult for a small child with PKU to understand why they can’t eat the same foods as everyone else. If possible, make your child’s PKU meals similar to the family meal. For example, if the family is having a stir-fry and rice, serve your child stir-fried vegetables with low protein rice.

Create a pleasant mealtime environment

Parents and siblings can be good role models for young children. Eat meals together as often as possible and try to limit distractions such as TV. A relaxed atmosphere during mealtimes can help make this time enjoyable for the family.

Avoid battles over meals

Parents often become anxious when their children don’t eat, and children quickly pick up on this. It can happen especially when you have made a lot of effort to prepare meals for your child with PKU. Some children refuse to eat, knowing it is an effective way to gain attention. It is never a good idea to force-feed a child. Continue to offer new foods and praise your child for trying something different.

Educate your child about PKU ‘friendly’ foods

Your child may want to eat foods that are not appropriate for their PKU diet; educate your child about which foods they can have and support positive food choices. Set a good example by encouraging family members to eat plenty of fruits and vegetables.
