If you’re a fan of diet soda or a meticulous ingredients reader, you may have noticed the warning “contains phenylalanine” on every can or bottle of diet soda you’ve ever had. For most of us, that warning doesn’t hold much significance. But for a small percentage of the population living with a rare genetic disorder called phenylketonuria (PKU), it’s a matter of life and death.

Phenylalanine is an essential amino acid that our bodies need for various functions, such as protein synthesis and the production of important substances like adrenaline and dopamine. While it can be found in natural food sources like meat and fish, it is also present in artificial sweeteners like aspartame, which is commonly used in diet soda.

For individuals with PKU, their bodies cannot properly process phenylalanine due to a lack of the enzyme phenylalanine hydroxylase (PAH). As a result, high levels of phenylalanine can accumulate in the body, leading to severe health effects such as intellectual disability, seizures, and tremors if left untreated.

The primary treatment for PKU involves adhering to a strict low-phenylalanine diet, which means avoiding foods like meat, fish, eggs, and even diet soda. However, recent advancements in research have shown promise in finding alternative treatment options for PKU.

Scientists have discovered that certain plants possess an enzyme called PAL, which can break down phenylalanine into harmless byproducts that can be easily eliminated from the body. In 2018, PAL became available as a daily injection to help manage phenylalanine levels, allowing individuals with PKU to potentially transition to a more typical diet.

In addition to PAL, researchers are also exploring gene therapy experiments to treat PKU. Preliminary studies using mouse models have shown promising results, with genetically edited viruses being used to introduce the PAH-producing gene into the liver. While more research is needed to determine the safety and efficacy of these therapies in humans, the progress is encouraging.

If you’re wondering whether you could have PKU and need to be mindful of phenylalanine warnings, chances are you would already know if you have the condition. PKU tests have been routinely administered to newborns in many countries since the mid-1970s.

So, the next time you see a warning on a product that may not affect you personally, remember that it could be crucial for someone else’s health and well-being. Phenylalanine warnings on soda cans and other products are a brand’s way of being transparent and responsible to the consumer.
