Bloated? Anxious? Here Are 5 Signs You Might Have A Food Sensitivity

Hey guys!

One of the most useful things I learned in my 90 Day Journey was how some foods just don’t agree well with my body. I can’t believe how much of a difference it made to just PAY ATTENTION.

For example, I get the worst breakouts when I eat dairy. And when I eat bread or some certain types of grains…ugh I just feel bloated and my digestion gets all out of whack.

Everything I learned made me want to learn even more. What are some signs that could mean your body is sensitive to certain foods? Things that maybe you’ve just been dealing with for YEARS without ever knowing that you could feel a lot better if you just adjusted your diet a bit?

Dietitian Breanna Woods helped me figure some of this out for you!

Tummy troubles

Any kind of sign that your gut isn’t happy could mean that something you’re eating just isn’t agreeing with you.

I’m talking about things like:

  • Bloating
  • Diarrhea
  • Constipation
  • Nausea
  • Stomach ache

For me, this is when I started to realize that grains might be a problem for me.

Some people notice this with dairy too. Actually, A LOT of people. Dairy sensitivity/lactose intolerance is sooo common. It’s estimated that 65% of the world has some level of intolerance!!

Another common food that might make you bloated, gassy, and all that fun stuff is sugar substitutes. A lot of the sugar-free foods you see contain sugar alcohols, which a lot of people have trouble digesting.


If you’re prone to headaches or migraines, it might be worth looking into a food sensitivity.

Migraines especially are known to have “trigger foods” like caffeine, sugar, salt, artificial sweeteners, and fermented foods like wine and aged cheese. If you tend to have migraines, a food journal might help you pinpoint the food(s) bothering you.


There are soooo many reasons why you could be dealing with fatigue. A food sensitivity is one cause that a lot of people don’t know about!

Runny Nose

If you’re constantly getting a random runny or stuffy nose… or you have stuffiness that just never goes away, it could be something you’re eating. Certain natural chemicals in foods and some food additives (like amines, salicylates, and sulfites) can trigger these symptoms if you’re sensitive to them.


Feeling anxious lately? Or maybe you’re having a hard time falling asleep.

If you drink coffee, soda, or energy drinks, it could be the caffeine. Even if you don’t drink a lot, you could be a little caffeine-sensitive.

Food Sensitivity vs. Food Allergies

There is a difference!!!

Food allergies are serious and actually trigger your immune system. Symptoms happen almost immediately and usually involve things like swelling, rash, difficulty breathing, and really scary stuff.

If you ever think you might have an allergy, you need to get it checked out with your doctor.

Food sensitivities aren’t life threatening and they can take awhile to show symptoms. Sometimes even days! That’s why people don’t even realize they have one! The only real way to test for a sensitivity is to try elimination. So for example, if you notice you’ve been bloated more than usual and suspect that dairy is the culprit, you’d eliminate dairy for a few weeks and see if you feel better. Then, you’d slowly add it back in to see if the bloat comes back.

Do any of these food sensitivity symptoms surprise you?!
