Gluten-Free Foods: Are They Actually Healthy?

Not too long ago, if you didn’t have a gluten intolerance or had celiac disease, the idea of a gluten-free diet probably drew up a blank for most people. Now, ‘gluten-free’ is taking over restaurant menus and supermarket isles as it is perceived as a healthy alternative diet. Is it just today’s trend or is there really something to it?

Gluten is a natural protein found in some grains like wheat, barley and rye. It acts as a binding agent-it’s what gives dough its elasticity and grain-based products their shape, texture and strength.1 Think of when a baker is rolling dough for bread, or a pizza-maker throws the pizza dough into the air: without gluten, the dough would rip apart.

What does gluten do to the body?

You find gluten in common foods like pizza, bread, pasta and cereals, but gluten provides no essential nutrients for our body.2 In fact, it is the only protein that is indigestible. 

For those of us who don’t suffer from intolerances or celiac disease, gluten passes through our system virtually unnoticed. For people with celiac disease however, eating gluten triggers an immune reaction, which causes inflammation and damage to the intestines and other parts of the body.2 If people with celiac disease keep consuming gluten-rich foods, their digestive system can become so damaged it stops absorbing nutrients from food all together.3 

Gluten-free diet: is gluten free healthy?

So, for people with gluten-intolerance or celiac disease cutting back or eliminating gluten-rich foods from their diet is crucial. But what about the rest of the human population?

When it comes to the health benefits of a gluten-free diet, opinions are divided. According to a survey by the Consumer Reports National Research Center published in 2014, gluten-free diets tend to be more nutritious, containing more vitamins and minerals.6 Studies by Harvard Health School say it’s just the other way around: gluten-free foods are usually less fortified with folic acid and minerals such as iron than conventional foods. It has also been observed that gluten-free food products often contain less fiber, more sugar and more fat, leading to more weight gain and higher chances of obesity-often the result of increased additives used to make up for taste and texture 2,4

Basically, just because a product is labeled ‘free from gluten’, it doesn’t make it healthier by definition. Make sure to always check the food label for nutritional content, additives, and hidden sugars if health is your priority. 

How are products “gluten-free”?

We see a lot of “gluten free” products in the supermarket today and each of these products must comply with certain regulations. So, when can we consider a product truly free from gluten?

Industrial process for removing gluten* 

Many “gluten free” products have been industrially processed to remove gluten or have been produced with alternative ingredients. Wheat consists mainly of fiber, starch and gluten protein. To extract gluten from wheat, it is milled into flour. This is turned into dough, so that the starch can be washed out, since starch dissolves in water but gluten doesn’t. By applying this process, the gluten protein is separated from the starch solution, which can be drained off and dried.7

*This method must be industrially done and does not work at home.

When is a product considered “gluten-free”?

All in all, a food can be labeled gluten-free when the product contains no more than 20 parts per million (ppm) of gluten. This is in part because current technologies are unable to reliably measure gluten presence below 20ppm, but also because such a small amount of gluten shouldn’t have any negative impact on people suffering from celiac disease.4

Why can the same food sometimes be gluten-free and sometimes not?

Part of labelling a product as “gluten free” depends on where the food is made. Even though some foods are naturally gluten-free, they can’t always get the gluten-free label because they have been “contaminated” as they were processed in a facility that also processes gluten products.4 For example, oats are naturally free from gluten but often don’t get the gluten-free label because they are grown nearby or are processed in the same facilities as other grains that do contain gluten like spelt, farina and wheat berries.1

So, is going gluten free good for you?

For those who are sensitive to gluten or gluten intolerant, the increased availability of gluten-free products is definitely a good thing. If you don’t have celiac disease or intolerance, there’s no reason to avoid gluten. In fact, like with many other food labels, food manufacturers are very generously using such labels in their marketing, which generally also translates into a higher product price.

So it is up to you if you’d like to try out the gluten-free life. Would you try to live gluten-free?
