Food allergy vs food intolerance: why allergy free doesn’t equal ‘eat what you want’

According to foodallergy.org, up to 15 million Americans have food allergies, including 5.9 million children under age 18. Food allergies have greatly changed celebrations and lunches at schools as well as food handling in other public places over the past few years. This may make you extra thankful that you don’t have food allergies. But just because you haven’t had an allergic reaction doesn’t mean you should eat whatever you want. In fact, considering food allergy vs food intolerance, you may need to be more mindful of what you eat.

Defining food allergy vs food intolerance

When you experience a food allergy, your immune system sees the food as an enemy and launches an attack on it with an antibody. This can result in hives, an itchy throat, difficulty breathing or in severe cases, anaphylaxis.

A food intolerance occurs in your digestive system when you can’t properly digested the food, due either to lack of enzymes or a sensitivity to additives and chemicals in the food. Symptoms can take longer to surface and can be more subtle, such as congestion, headaches, stomach pain, joint pain or irritability, just to name a few.

Understanding why food tolerance could be more dangerous than a food allergy

Because your body reacts to a food allergen immediately, it’s difficult to ignore or mistake the symptoms as something else.

But your symptoms can be subtle or ambiguous with a food intolerance, which means:

  • you could suffer from a food tolerance for years before realizing it, overworking and weakening your body, slowly but steadily.
  • if damage has set in over many years, that damage is harder to undo.
  • your damaged immune system can make you more vulnerable to other sicknesses, and it can cause loads of other issues – even asthma, hyperactivity or skin issues – to be more extreme.

So with a food intolerance, you could generally be feeling OK, with a little nagging chronic symptom – like outdoor allergies or headaches – and simply chalking it up to allergies or weather patterns. But if you linked those outdoor allergy symptoms or headaches to a food, you could find relief from those symptoms and give your body time to heal by avoiding that food for a while, or permanently if needed.

How can you diagnose a potential food intolerance?

Of course, you can get the typical IgE test for food allergies. Or if you request, the physician might do the IgG test, which is more accurate for determining food intolerances, in addition to allergies. But these tests are not as reliable as it is to simply listen to your body.

If you suspect a food intolerance, don’t be discouraged or afraid you’ll lose the foodie love of your life forever. Instead:

  1. Eliminate the suspect food(s) for 3 weeks.
  2. Add one food back in to your diet at a time, eating a reasonable amount of it in small doses over 1-2 days. Wait 3 days before reintroducing another new food. Record any symptoms in a food journal.
  3. If you don’t notice any symptoms, try adding the food back into your rotation moderately. If you do have symptoms, avoid that food and find a replacement for it if needed. Just search online for recipes or foods without your culprit. Also research alternate names for that culprit and make sure it’s not in any of your other cosmetic products (like yellow 5 = tartrazine).

Below is a list of common symptom-causing foods I compiled from various resources for my book, Digested – eating healthier made easier 3 ways. Some of the symptoms may surprise you!

food allergy vs food tolerance

In food allergy vs food intolerance, the allergy is actually easier to detect. But if you have chronic symptoms of any sort, take a closer look at the foods you’re eating. You could potentially reverse your symptoms – get relief for now – and give your body a break so that you may feel even more amazing after it’s had time to heal.
