Are you gluten intolerant? A new enzyme pill can offer relief

Researchers have found a new enzyme, AN-PEP, which when consumed as part of a gluten containing food, enable gluten-sensitive patients to ingest small quantities of it without experiencing symptoms such as bloating, diarrhea and abdominal pain.

With more and more people avoiding any wheat-based foods that might have uncomfortable side effects, the market for gluten-free foods has exploded in recent years, but a unique enzyme pill promises to change all of that.

Researchers have found that taking an enzyme tablet while consuming foods containing gluten prevents a significant amount of it from entering the small intestine. This could enable gluten-sensitive patients to ingest small quantities of gluten without experiencing symptoms, such as bloating, diarrhea and abdominal pain.

The encouraging results from the enzyme known as aspergillus niger-derived prolyl endoprotease (AN-PEP) were presented at Digestive Disease Week (DDW) 2017.

“This substance allows gluten-sensitive patients to feel safer, for example, when they are out with friends at a restaurant and can’t be sure whether something is 100% gluten-free,” said lead author Julia König from the University of Örebro, Sweden. “Since even small amounts of gluten can affect gluten-sensitive patients, this supplement can play an important role in addressing the residual gluten that is often the cause of uncomfortable symptoms.”

Gluten intolerance is a disease that deteriorates with time and once it leads to a severe health condition, it is difficult to pull a patient back.

The study found that AN-PEP, in both high and low doses, broke down gluten in both the stomach and the first part of the small intestine, or duodenum. In the stomach, gluten levels in both the high- and low-dose groups were 85% lower than in the placebo group. Once the food reached the duodenum, gluten levels were reduced by 81% in the high dose group and 87% in the low dose group versus placebo.

“Studies show that even when following a gluten-free diet, unintentional gluten intake can still occur, depending on how strict a gluten-free dieter is,” added König. “Our results suggest that this enzyme can potentially reduce the side effects that occur when gluten-sensitive individuals accidentally eat a little gluten. We are not suggesting that AN-PEP will give these individuals the ability to eat pizza or pasta, sources of large amounts of gluten, but it might make them feel better if they mistakenly ingest gluten.”

König noted that her team did not test the enzyme on celiac disease patients, because even small amounts of gluten can cause long-term harm in these individuals. Because of that, she does not recommend celiac patients view this enzyme as a way to start eating any gluten.
