Food Sensitivities and Food Allergies: How False Perceptions Can Disrupt Nourishment and Exacerbate Eating Disorders
By Thrive Waco Registered Dietitians Courtney Anderson M.S., RD, LD, CLC, and Sheridan Faye Glaske, M.S., RDN, LD
The diet industry has put its twist on the topic of food allergies in an effort to leverage yet another misleading strategy for unhealthy weight loss, and subsequently encouraging dangerous elimination diets unsupported by clinical evidence. With this latest tactic by diet culture , more and more individuals are misled and mistakenly believe they are food allergic. Research suggests that nearly 19% of U.S. adults believe they have a food allergy, but only 11% percent of U.S. adults are actually diagnosed with one. While food allergies are real and can be dangerous, the implications of eliminating foods from one’s diet without professional guidance can also be detrimental. For individuals struggling with eating disorders , the fad of food allergies can be especially disruptive to their relationship with food, providing them with a fashionable, yet extremely hazardous, excuse to neglect to nourish their bodies.
FOOD ALLERGIES: POTENTIALLY LIFE-THREATENING REACTIONS
A food allergy occurs when the body’s immune system mistakenly attacks a usually harmless protein found in food.
The most common food allergies include:
- Peanuts
- Tree nuts
- Wheat
- Soy
- Eggs
- Milk
- Fish
- Shellfish
Symptoms of food allergies include:
- Hives
- Itching
- Swelling
- Wheezing
- Dizziness
- Trouble breathing and swallowing
Food allergies are serious and if symptoms are severe enough, anaphylaxis can occur, which can be life-threatening.
FOOD SENSITIVITIES: TRENDY, BUT DISRUPTIVE TO NOURISHMENT
As the topic of food allergies has garnered more mainstream attention, the practice of self-diagnosing food sensitivities — a milder food intolerance — has also become popular. While specific foods can in fact cause digestive upset for some, the self-diagnosis of food sensitivities isn’t supported by consistent clinical findings and is not recommended by experts.
In extreme cases, the false perception of food sensitivities may encourage affected individuals to unnecessarily eliminate a wide variety of foods from their diet. When a person experiencing gastrointestinal issues mistakenly attributes their symptoms to a food sensitivity, they may overlook the underlying causes of their digestive struggles. To make matters worse, their limited dietary intake may begin to negatively affect their well-being.
FOOD ALLERGIES, FOOD SENSITIVITIES, AND EATING DISORDERS
For those struggling with eating disorders, falsely believing they have food allergies or food sensitivities can be arguably more dangerous than food allergies themselves.
Individuals with eating disorders commonly experience digestive issues , especially when suffering from malnutrition and starvation .
These uncomfortable gastrointestinal symptoms include:
- Constipation
- Diarrhea
- Bloating
- Acid reflux
- Nausea
Attributing their gastrointestinal symptoms to food allergies or sensitivities may provide them with what they believe to be a simpler and perceivably more socially acceptable explanation. However, this is risky for many reasons. Before exploring any food allergies or sensitivities, a person struggling with an eating disorder should undergo dietary assessment, nutritional rehabilitation, and weight restoration guided by an experienced and multidisciplinary treatment team that takes all aspects of well-being into consideration. Most often, once an individual eats a wide variety of foods adequately and consistently for a sustained period, any digestive symptoms diminish and eventually disappear.
TREATING TRUE FOOD ALLERGIES AND SENSITIVITIES
Using different tests to identify food allergies and their severity, only qualified allergists can accurately diagnose food allergies. Although trendy, at-home tests aren’t effective or accurate ways to identify food allergies and sensitivities.
Treating true food allergies requires individuals to abstain from eating the food to which they’re allergic. However, when this is the case for those with eating disorders, close planning and monitoring by a registered dietitian is necessary to ensure the avoidance doesn’t lead to any nutrient deficiencies.
It’s important to distinguish between a food allergy and a mild sensitivity. For those with sensitivities to foods such as dairy, dietitians often encourage eating small doses of lactose-containing foods. By treating food sensitivities this way, it’s possible to decrease one’s symptoms, prevent complete intolerance, and avoid any unnecessary elimination of nutrients.
