Navigating a Gluten-Free Diet

Samuel Gee, a British doctor, is regarded as the father of modern celiac disease. In 1887, he referred to the condition as a 'chronic indigestion' likely caused by diet, although his early beliefs about the specific dietary triggers were later disproven [source: Fasano]. Following World War II, Willem-Karel Dicke, a Dutch pediatrician, observed that fewer children died when bread was unavailable during the war, and their mortality rate increased again once bread was reintroduced. This led scientists to identify gluten, a protein found in wheat, barley, and rye, as the primary cause of celiac disease.

For individuals with celiac disease, consuming gluten damages the lining of the small intestine, which prevents the absorption of nutrients. This can lead to various symptoms, including diarrhea, stomach pain, muscle cramps, fatigue, depression, and a skin rash. The only way to manage this condition is by adhering to a strict gluten-free diet. Any deviation can cause further harm to the intestine.

For many people, the prospect of a gluten-free lifestyle feels overwhelming and disheartening. The diet can interfere with social activities; children may miss out on pizza parties and cupcake events at school, while young adults may struggle to find options when dining out with friends. Gluten-free products are often much more expensive than their regular alternatives. Additionally, those on a gluten-free diet may find it challenging, especially for more reserved individuals, who may need to contact manufacturers, question chefs, or inquire about wedding cake ingredients before they can eat.

In certain regions of the world, especially in Europe, gluten-free diets are far more prevalent. For instance, in Finland, it’s possible to walk into a McDonald's and order a gluten-free Big Mac. However, for those seeking a little more direction on where to begin, turn the page for a list of foods that are suitable—and those that are not.

Gluten-free Foods

The first step to adopting a gluten-free diet is to avoid all grains like wheat, rye, and barley, as well as any products derived from them. It’s crucial to check food labels to ensure these grains aren’t included. Unfortunately, wheat flour is commonly used in baking because gluten provides elasticity, giving baked items a light, airy texture. This means that most breads, cereals, pastas, crackers, cookies, and cakes should be avoided.

Yet, gluten can also be found in less obvious places, such as beer, candy, processed meats, soups, sauces, soy sauce, and salad dressings. Gluten is also frequently present in Communion wafers, vitamins, medications, lipstick, Play-Doh, and toothpaste. Always read labels carefully, and if uncertain, contact manufacturers to verify a product’s safety. Even products marked with a "gluten-free" label require scrutiny; the standards for what qualifies as gluten-free are still evolving in some cases.

What foods are safe to eat then? Nutritionists often suggest shopping around the perimeter of the grocery store, where fresh produce, unprocessed meats like beef, pork, poultry, and seafood can be found. Eggs, milk, unprocessed cheese, yogurt, and butter are also good to go. There are also gluten-free options in the center aisles, such as plain potato chips, popcorn, unsweetened nuts, and packaged fruits and vegetables. Not all grains are off-limits either; you can enjoy naturally gluten-free grains like corn, potato flour, quinoa, rice, and soy. Dining out with celiac disease involves coordinating with restaurants to find safe ingredients and possible substitutions. More restaurants catering exclusively to those with celiac disease are popping up.

The rise of gluten-free restaurants and the growing availability of gluten-free labeled products has allowed many individuals who cannot consume gluten to enjoy their favorite foods, like bagels and pastas. However, as this niche market continues to grow, questions arise about whether a gluten-free diet could have benefits beyond just those with celiac disease. Is it something everyone should consider?

Adopting a Gluten-free Diet

Many gluten-free products are available in health stores, leading some to believe that eliminating gluten from their diet is a healthier choice. These individuals may switch to a gluten-free lifestyle, but doctors warn that there is no evidence to support the idea that a gluten-free diet benefits anyone other than those with celiac disease. Those who feel better after going gluten-free often attribute it to a boost in energy, but this may simply be because processed wheat products cause blood sugar spikes followed by crashes, leaving people feeling sluggish. Instead of going fully gluten-free, it may be more beneficial to eliminate processed foods from the diet altogether.

Many individuals experiencing gastrointestinal issues might mistakenly assume they have celiac disease, but doctors advise against starting a gluten-free diet before receiving a proper diagnosis. A gluten-free diet can alter the antibody levels in the blood, which are essential for diagnosing celiac disease. Current guidelines suggest that people should only eliminate gluten once it is absolutely necessary. Additionally, just because a product is labeled gluten-free in a health food store doesn’t mean it’s entirely healthy. Some gluten-free foods can have higher fat and sugar content, which can benefit those with celiac disease who may be malnourished due to years of poor nutrient absorption. Those following a gluten-free diet should also consult with a dietitian to ensure they are receiving adequate nutrients through supplements, as gluten-free foods tend to be low in B vitamins.

As more people adopt a gluten-free diet, there’s growing concern that this might undermine the efforts of those who must follow a gluten-free lifestyle to manage celiac disease. While the increased availability of gluten-free products is a positive development, it could also lead to less stringent practices by manufacturers in preventing cross-contamination.

Cross-contamination poses a significant challenge for those on a gluten-free diet. To illustrate how it works, imagine a mother preparing sandwiches for her two children: one has celiac disease and the other does not. If she uses the same knife to spread jam on both gluten-containing bread and gluten-free bread, there's a risk that gluten particles from the regular bread will contaminate the gluten-free one. In restaurants, chefs should prepare gluten-free dishes in a completely separate area with dedicated utensils. Food packaging should clearly state if a product shares processing equipment with gluten-containing items.
