If you’re over the age of 20, chances are you’ve noticed it seems like almost everyone you encounter these days has some form of food sensitivity. Your local restaurant likely has menu items specifically marked gluten or dairy free, and your grocery store has significantly more allergen and food-sensitivity options available, if not an entire section dedicated to these products.
Food Allergy and Sensitivities Are on the Rise
Food allergies and sensitivities are becoming somewhat of an epidemic in the United States. The most concerning aspect of this is the sudden increase in the past three decades of people who have a diagnosed food allergy or sensitivity.Current statistics show that food sensitivities and food allergies are found in more than 20 percent percent of the population of industrialized countries. This is a high number, and it’s likely to be even higher due to a large number of cases gone unreported or undiagnosed.
Are Food Allergies and Sensitivities the Same?
While the terms food “allergy” and “sensitivity” often get used interchangeably, there is a significant difference between the two.Common Food Sensitivity Symptoms
When certain foods are continually consumed over a long, or even short, period of time, the immune system becomes dysregulated and symptoms occur. Many think of food sensitivities mostly affecting the gut and manifesting gastrointestinal symptoms, but in reality, they can also affect the skin, the brain, and have systemic implications.- Acne
- Brain fog
- Congestion or runny nose
- Constipation
- Depression
- Diarrhea or loose stools
- Eczema
- Fatigue
- Flare of autism or autoimmune symptoms
- Gas or bloating
- Headaches or migraines
- Heartburn
- Immune system impairment
- Insomnia
- Inflammatory bowel disease
- Irritable bowel syndrome
- Joint pain or inflammation
- Malabsorption of vitamins and minerals
- Rashes, eczema, or swelling
- Sinus infections
- Weight gain
Why Are Food Allergies, Sensitivities Increasing in Prevalence?
The increase in food allergies and sensitivities isn’t linked to one specific cause, but rather a combination of many things our bodies are fighting against.Glutathione is an antioxidant that fights cell-damaging molecules in our body. It helps us to break down nutrients we consume, repairs DNA, activates important enzymes, and inactivates toxins. If the glutathione in your body has been depleted by too much-repeated use of these types of medications or too many rounds of antibiotics over the course of your life, it’s likely that your body will have a negative response to food in some form.
Furthermore, these medications cause intestinal permeability, which contributes to the development of immune responses to foods.
It’s estimated that the average individual encounters at least 700,000 different toxins (though many believe that number to likely be as high as 2 million) every single day. These toxins are in cleaning products, bottled water, skincare and makeup, perfumes, soaps and detergents, air fresheners, furniture, plastic products, paint, the list could go on.
Our bodies are designed to encounter germs. This is essential for our immune systems to build up a natural defense against harmful bacteria, and to allow good bacteria to populate our gut. When this is removed, whether by the oversanitization of surfaces, or excessive use of hand sanitizer, etc, our immune system becomes hyper-reactive to germs and is unable to neutralize the fight.
Additionally, our digestive tract is unable to properly absorb and process nutrients, often manifesting in food allergies or sensitivities.
Processed foods are essentially any food product that has been changed from its natural state by refining and adding additional ingredients such as preservatives, fillers, gums, additives, etc. These ingredients cause inflammation in the gut, often leading to sensitivities for many individuals.
Why Test Food Sensitivities?
Many individuals live for quite a while with their negative symptoms, trying a variety of things to try and figure out what is causing their issues. Some remove dairy or gluten from their diet, and they start to see improvement but then feel like the symptoms are returning.The Benefits of Stool Testing
The vibrancy of the microbiome is foundational to how the body handles food. There are over 1000 different bacterial strains in the gut that are responsible for various tasks including immune function, managing inflammation, assimilation of nutrients, and ensuring proper barrier function. Furthermore, the microbiome can influence metabolic health, cardiovascular health, liver health, hormone health, among others.Identifying food sensitivities helps us remove inflammation and immediate symptoms quickly, but the stool test tells us why these symptoms are occurring.
- Intestinal permeability (leaky gut)
- Calprotectin
- Pancreatic elastase 1
- Bile acids
- Cholic acid
- Chenodeoxycholic acid
- Deoxycholic acid
- Lithocholic acid
- Acetic acid
- Butyric acid
- Propionic acid
- Valeric acid
- Total SCFAs
- SS-glucuronidase
- Bacterial species involved with SIBO, IBS, IBD
- Fungal species
- Parasites and worms
- Viruses
Common Food Sensitivities
While there are a wide variety of foods that people may have sensitivities to, the most common are:- Gluten
- Conventional dairy
- Eggs
- Corn
- Soy
- Nuts
- Nightshades
Gluten Cross-Reactivity
If you’ve removed gluten from your diet but are still experiencing symptoms, you may be dealing with gluten cross-reactivity. This happens when your body notices a food you are consuming has a similar protein sequence to gluten. Essentially, your body says “Hey! I recognize this, and we know it’s bad,” producing the same immune response as it does with gluten.- Corn
- Rice
- Oats
- Millet
The Elimination Diet
The elimination diet removes foods that are known to drive inflammation and symptoms as well as a careful reintroduction period to rule out food reactions. This plan is designed to remove potentially problematic foods in order to decrease inflammation in the body, rebalance the gut flora, soothe the gut lining, regulate blood sugar, modulate the immune system, resolve nutrient deficiencies, and bring overall healing to the body. My book, “Restorative Kitchen,” is an extensive cookbook and guide for an elimination diet.Rotational Eating
Another strategy to identify food allergies and sensitivities is with rotational eating. Rotational eating is essentially consuming foods from a specific food group that has biological similarities, and then taking a break from eating them for several days (at least 3) before consuming again. This gives time for you to record any symptoms or reactions your body might be having to the food group, while also helping your body to have time to process food groups that might be inflammatory. It’s essentially a “time out” for your immune system to allow it to regulate itself properly, instead of being constantly inundated with inflammation-triggering foods.When you’re doing a rotational eating plan, making an extra concerted effort to eat seasonally will help with this. We aren’t designed to eat the same 20-30 fruits, vegetables, and meats year-round. Shopping at your local farmers market, produce stand, and developing relationships with any local farmers in your area will make eating seasonally much easier. Even when you’re not doing rotational eating, your body will thank you for making the effort to consume food with the seasons.
Dealing with symptoms that seem to constantly come and go and change often can be incredibly frustrating and discouraging. You might feel like you eat “healthy,” but still have sensitivities. Following some of the strategies we discussed today can make a big difference in helping you eliminate food triggers and begin your journey to healing. However, as we mentioned earlier—it’s important to also work with a trusted practitioner who can help you identify the root of the problem.
While walking the road to identify and treat your food allergy or sensitivity symptoms can seem like a long one, when you allow your body to heal, you will be so grateful you did! Health is wealth, friends.
