Being anxious, tired, or even suffering from joint pain is often dismissed as part of the stress of modern life.
But they could be signs of food intolerance – and if you just cut something out of your diet, you can improve your health and well-being.
Experts have now discovered the six most common symptoms that show that your body reacts to a specific food that you eat.
Often confused with allergies, food intolerances are completely different.
The symptoms can last up to 72 hours and vary from person to person.
Dr. Gill Hart, biochemist and scientific director at YorkTest Laboratories, said, "Food intolerance can occur when your body is having trouble digesting certain foods.
"If this happens over time, large protein particles from food can enter the bloodstream.
"The immune system sometimes sees these particles as a threat and produces antibodies to attack them.
"The body's immune system reacts with inflammation, it's this inflammation that can trigger symptoms that can develop over time and cause symptoms if left untreated."
Here are six signs of food intolerance.
1. fatigue or exhaustion
The most common cause of fatigue is lack of sleep, but science has shown that eating and drinking can have a big impact on your energy levels.
Dr. Hart said, "Many people associate food intolerances with digestive problems such as flatulence and irritable bowel syndrome (IBS).
"Fatigue and low energy are also symptoms of food intolerance.
"In fact, one in five people who came to YorkTest for testing last year did so because they suffered from fatigue."
2. Itchy skin or eczema
Food intolerances can also lead to skin complaints, says dr. Hard.
She added, "If you have persistent bouts of itchy skin for no apparent reason, it may be a good idea to rethink your diet.
"People who tend to develop eczema are considered" atopic, "which means they have an overactive immune system that causes their skin to become easily inflamed.
"If you eat something that causes inflammation in the body, there is a chance that it will affect your skin, which means that maintaining an eczema-friendly diet can be crucial in managing inflammation."
3. IBS symptoms
Symptoms of Irritable Bowel Syndrome (IBS) include abdominal pain, excessive wind, flatulence and constipation.
IBS can be triggered by certain foods that irritate the digestive system and can also be a symptom of food intolerance.
Dr. Hart said, "Studies have shown that the irritable bowel is associated with a hypersensitive gut and many people find relief by removing certain foods from their diet."
4. Joint pain
Do you have general pain that can not be explained by an underlying condition?
It might be wise to look at what you eat.
Dr. Hart said, "If you have general joint pain, it might make sense to consider what your diet is all about, as food intolerance could contribute to these issues."
According to the Arthritis Association, what you eat can cause inflammation in the body and joints that can lead to pain.
They say that foods that can cause inflammation include sugars, saturated fats and trans fats found in foods like pizza and cheese.
If you are constantly afraid, it may be worthwhile taking a look at what you put into your body.
Dr. Hart said, "Research has shown that gastrointestinal inflammation, one of the common symptoms of food intolerance, is common in patients with signs of depression and anxiety.
"The relationship between gut and mental health is often bi-directional.
"When you feel depressed, your digestive system's health is likely to suffer, and having stomach problems increases the likelihood of depression and anxiety.
"Food reactions vary greatly from person to person, and an ingredient that can cause problems for one person may be fine with another person.
"We call this our personal" food fingerprint. "That's why food intolerances can be so hard to locate without help."
Migraines are throbbing, severe headaches that can also be accompanied by nausea, vomiting and sensitivity to light, noise or smell.
The University of York conducted a survey to understand the benefits of elimination diets based on the results of a food intolerance test.
Out of 259 people who experienced migraine, 76 percent said that their "trigger" foods improved.
What can you do and how can you be tested?
Dr. Hart said, "Food intolerances can affect many areas, including digestion, skin, energy levels, breathing, joints, and even mental health.
"In our experience with YorkTest, the most common symptoms of food intolerance range from migraine, eczema, IBS symptoms and flatulence, joint pain, asthma, fatigue and anxiety.
"The NHS does not currently offer food intolerance testing. Instead, people are asked to remove certain foods individually to determine intolerance.
"However, this can often be difficult as the symptoms do not appear until 72 hours after eating a 'problematic' food.
"At YorkTest, we analyze IgG responses to a variety of food and beverage ingredients.
"We always encourage people worried about symptoms to visit their family doctor first to rule out any underlying conditions."
