Food Intolerance:
Food intolerances are defined as difficulty in digesting a particular food, are different than food allergies. Food allergies involve the immune system, whereas food intolerances generally do not.
In a British study of more than 10,000 patients, the foods most often associated with intolerances were chocolate, food additives, citrus fruits, fish, shellfish, milk, cheese, eggs and nuts. The most common symptoms of these intolerances were hay fever, headaches, joint pain, itching, hives and stomach discomfort.
In the largest study to date, doctors studied the electronic health records of 2.7 million patients in the US. They found that 3.6 percent had at least one food intolerance or food allergy. The list of offending foods was similar to that of the British study.
In both studies the investigators were unable to discriminate between food intolerances and food allergies. Because the symptoms overlap extensively, one cannot differentiate intolerance from allergy without specialised testing. And that's what we do in India.
If you are travelling abroad, you must take this test while in India as it can help you prevent digestion issues and stomach pain while travelling. You will know what to eat!
