Can My Symptoms Actually Be a Food Intolerance?

Food intolerance or sensitivities can effect you in so many ways. They’re a lot more common than most people think. I'm not talking about immediate allergic reactions that involve an immune response which can be serious and life-threatening.  If you have any allergies, you should steer clear of any traces of foods you are allergic to and speak with your doctor or pharmacist about emergency medication, if necessary. What I'm talking about is an intolerance; meaning that you do not tolerate a specific food very well and it causes immediate or chronic symptoms anywhere in the body. Symptoms can take hours or even days to show themselves and can be located just about anywhere in the body. This is what makes them so tricky to identify.

Symptoms of food intolerances

There are some common food intolerances that have immediate and painful gastrointestinal symptoms, such as lactose intolerance or Celiac disease. These can cause stomach pain, gas, bloating, and/or diarrhea.  Symptoms can start immediately after eating lactose or gluten. Other symptoms may not be linked to foods in an obvious way. Symptoms like:
  • Chronic muscle or joint pain
  • Sweating or increased heart rate or blood pressure
  • Headaches or migraines
  • Exhaustion after a good night's sleep
  • Autoimmune conditions like Hashimoto's or rheumatoid arthritis
  • Rashes or eczema
  • Inability to concentrate or feeling like your brain is "foggy"
  • Shortness of breath
If your body has trouble digesting specific foods, it can affect your hormones, metabolism, or cause inflammation and result in any of the symptoms listed above. These can affect any part of the body, not just your gastrointestinal system.  

How to prevent food intoleranceGF DF badge

The main thing you can do is to figure out which foods or drinks you may be reacting to and stop ingesting them. The best way to identify your food or drink triggers is to eliminate them for three full weeks and monitor your symptoms. If things get better, then you need to decide whether it's worth it to stop ingesting them or if you want to slowly introduce them back one at a time while still looking out to see if/when symptoms return.  

Start Here: Two common food intolerances

Here are two of the most common triggers of food intolerance:
  • Lactose (in dairy - eliminate altogether, or look for a "lactose-free" label - try nut or coconut milk instead).
  • Gluten (in wheat, rye, and other common grains - look for a "gluten-free" label - try gluten-free grains like rice, quinoa & oats).
This is by no means a complete list, but it's a good place to start. Lactose intolerance is thought to affect up to 75% of people, while non-celiac gluten sensitivity can affect up to 13% of people. If you can eliminate all traces of lactose and gluten for three weeks, it can confirm whether either or both of these are a source of your symptoms. Yes, dairy and grains are a part of many government-recommended food guidelines. However, you can get all of the nutrients you need if you focus on replacing them with nutrient-dense foods. A reliable way to monitor how you feel after eating certain foods is to track it (check out the food diary/journal download below).  After every meal or snack, write down the foods you ate and any symptoms so you can more easily spot trends. Click here to download a free copy of my Weekly Diet Diary/Food Journal to help you monitor your symptoms. As mentioned earlier, symptoms may not start immediately following a meal. You may find, for example, that you wake up with a headache the morning after eating bananas. You might be surprised what links you can find when you track your food and symptoms! When in doubt, ask the server in a restaurant about hidden ingredients, read labels on sauces/packaged foods, or consider cooking at home from scratch (its the best way to monitor how you are feeling). IMPORTANT NOTE: When you eliminate something, make sure it's not hiding in other foods or the whole point of eliminating it for a few weeks is lost. Restaurant food, packaged foods, and sauces or dressings are notorious for adding ingredients that you'd never think are there. You know that sugar hides in almost everything, but did you also know that wheat is often added to processed meats and soy sauce? Even lactose can even be found in some medications or supplements! It's really important to read the ingredient labels. If you are unsure of any ingredients.   What if it doesn’t work? If eliminating these two common food intolerances doesn’t work, then you can go one step further to eliminate all dairy (even lactose-free) and all grains (even gluten-free) for three weeks. You may need to see a qualified healthcare practitioner for help, and that's ok. I don't want you to continue suffering if you don't need to!     Recipe (dairy-free milk): Homemade Nut/Seed Milk Makes 3 cupsalmond milk
