It is well known that the most common cause of fatigue is lack of sleep, but there are other reasons for tiredness, including allergies to certain types of food. The relationship between food and fatigue is not straightforward; it is entirely normal to feel tired after consuming a large amount of food or drink. Your body works hard to digest and process the foods, and sometimes this consumes a lot of energy, leading to feelings of fatigue. If you feel exhausted all the time, especially after certain meals, it is likely that you are suffering from food intolerance or allergies to some foods. If you experience any of the following symptoms after eating certain foods, your fatigue may be due to intolerances to those foods, according to the British newspaper Express:
- Drowsiness
- Headache
- Dizziness
- Abdominal pain
- Diarrhea
- Rash
What foods cause fatigue?
If food intolerance is the basis of your chronic fatigue, there are some common foods that may be the culprit. Experts at York Test state that people often assume that gluten, lactose, dairy products, or wheat are the problems, but "there is no evidence that any specific food causes fatigue or any other symptoms." The experts explained, "Everyone is different and has a unique fingerprint of foods, and even foods that are considered healthy, such as fruits and vegetables, can cause allergies in some." The only way to find out which foods cause you fatigue is to undergo a food intolerance test.
