Getting diarrhea every time you eat egg salad is often caused by having an egg allergy or an egg intolerance.
When you have an egg intolerance or egg allergy it causes you to have a sensitivity to egg whites or egg yolks, which causes digestive issues such as diarrhea.
Egg allergies also often include throat swelling or hives, but egg intolerance's often just result in and cause cramps, diarrhea, and bloating within a few hours of eating eggs or egg salad.
The high fat ingredients or even the other ingredients like celery, spices like mustard or onions can also trigger sensitivities or even irritate your gut, especially if you have irritable bowel syndrome.
Egg salad also contains a lot of mayonnaise, and high fat and creamy foods can also be difficult to digest and can result in diarrhea.
If your body doesn't produce enough digestive enzymes, such as pepsin, it cannot properly break down the egg proteins, which lead to digestive issues.
Egg salad gives you gas because the eggs in the egg salad contains high sulfur content.
The egg yolk in the egg salad contains a high amount of sulfur, which your gut bacteria ferment into hydrogen sulfide gas.
The combination of high sulfur and protein rich egg whites and high fat egg yolks can slow digestion, which allows for more fermentation time.
Also the addition of onion, garlic or mayonnaise can also trigger bloating or in some cases, which can also indicate a food sensitivity.
The main culprit for the gas from egg salad is the sulfur content in eggs.
Eggs are rich in sulfur containing amino acids, also known as methionine.
And when the sulfur containing amino acids are broken down, they produce hydrogen sulfide, which causes the smelly and sulfurous gas.
The fat in the egg yolks in egg salad also slows down digestion, which can also lead to increased fermentation and gas in your gut.
For some people they may have digestive issues and digestive intolerances as well, which can also lead to the gas in people who eat eggs and egg salads.
Some people have a mild and non allergic intolerance to egg protein, which cause the body to struggle with digestion and result in bloating and gas.
Ingredients that are often paired with egg salad like garlic, onions, celery or mayonnaise can also cause gas and indigestion in people, especially in people that are sensitive.
Hard boiled eggs, which are the base of egg salad are also dense and harder for some people to digest when compared to other types of eggs.
Egg salad can be harder to digest for some people and others may have no issues with digesting egg salad.
It's normal though for some people to get gas or even bloating when eating eggs or egg salad and it's usually nothing to worry about.
