Can Food Allergies Cause Sleep Apnea?

can food allergies cause sleep apnea?An undiagnosed sensitivity to certain foods you enjoy during daytime meals may aggravate your sleep apnea at night. An estimated 25 million Americans experience sleep apnea. Approximately 32 million Americans also suffer from food allergies.2 Naturally, what we eat may be impacting how we sleep. Here’s a closer look at the relationship between the two and which specific foods to avoid that may worsen symptoms. 


Can Food Allergies Cause Sleep Problems?

Food allergies can cause someone’s immune system to have a reaction that results in inflammation in the body and tissue swelling. These reactions could result in loss of sleep or a poor night’s sleep.

Sleep Apnea and Food Allergies

If someone is experiencing sleep apnea symptoms, food allergies can worsen and/or trigger them. These symptoms can include:

  • loud snoring
  • daytime sleepiness
  • waking up frequently

How Food Allergies Trigger Sleep Apnea 

Food allergies are triggered by the body’s immune reaction to particular foods. Inflammation results and tissues swell, which leads to increased mucus production. Both the inflammation and swelling in the tissue block the airway which cuts off the flow of oxygen to the brain. In response, the body tells the brain to wake up. The sudden jolt often leaves the person gasping for air. Simplified, increased mucous translates to more apneas as you sleep. 

What to do if You Think Food is Affecting Your Sleep?

If you think you are allergic to certain foods and they are affecting your sleep, first try cutting those certain foods out of your diet and see if that helps. You can also talk to your doctor and they will help you pinpoint which foods may not be the best for you. 

Testing Your Sleep Quality and the Foods You Eat

If you are unsure if you have a food intolerance, start first by avoiding certain foods known to aggravate sleep disorders and see if your night improves. Also, keep a food diary and record what you eat. This will be useful to evaluate the impact of those foods on your sleep. 

Common Foods That Impact Sleep

Some common foods intensify sleep disorder symptoms. These include:

  • Bananas. While bananas are rich in potassium and other nutrients, they also contribute to mucus production. More mucus leads to congestion as you sleep. Try avoiding bananas for a period of time and see if you experience improvements in your sleep quality.
  • Dairy Intolerance. Much like bananas, high-fat dairy—ie, whole milk and high-fat cheeses—increases mucous. Even if you only have a mild intolerance to dairy, it may still be contributing to a night of restless sleep. 
  • High-Fat Meats. In addition, foods like steak or hamburgers may intensify your sleep apnea symptoms. High-fat meats like beef increase inflammation which can narrow airways and aggravate apneas.3

Common Foods that Improve Sleep

Here are some of the foods that can help you improve your sleep and fight sleep disorders:

  • Fatty Fish. Fatty fish might help improve sleep as it provides a healthy dose of Vitamin D and Omega-3 Fatty acids. Both these vitamins and minerals are directly involved with the production of serotonin which helps improve sleep.
  • Nuts. Nuts like almonds, walnuts, and pistachios are good for the improvement of your night’s sleep. Although the amounts vary, the high quantity of minerals including both magnesium and zinc help in the production of melatonin that improves sleep.
  • Rice or Carbohydrate-Rich Food. Studies show that the intake of high amounts of carbohydrates can help people sleep well. Some studies show that the consumption of rice helps in a better sleep cycle compared to other heavy food items.
