"It's never too late"

"As a teenager, I just wanted to be like everyone else. It started with throwing away my protein substitute and before I knew it, I was no longer following the diet. I didn't notice the consequences right away, but my grades were deteriorating, I was irritable and constantly tired. When I went back on a diet, it was as if the fog lifted."

Katie, 31, PKU

Here are some common myths about a low-protein diet:

1. "I can manage my PKU by eating only low-protein foods."

The truth is: your body needs a Phe-free protein source. PKU protein substitutes are specially formulated to keep your diet nutritionally balanced. With a strict low-protein diet, you don't get all the essential nutrients.

2. "All protein substitutes and low-protein products taste bad."

The truth is: the science behind PKU protein substitutes has improved tremendously. There are now different flavors, shapes and preparation methods. Discuss with your dietitian which options suit you best.

3. "I have to take a lot of protein substitutes to get enough nutrients."

The truth is: there are several concentrated protein substitutes available, which means you don't have to drink or eat as much volume while still getting all the nutrients you need.

4. "I'm too old to start a protein substitute again."

The truth is: it's never too late! At any age, reintroducing a PKU protein substitute can help to reduce symptoms such as fatigue and difficulty concentrating.
