Hi, your symptoms could be due to food intolerance. This can cause mild symptoms which may not be noticeable. Up to 20% of the population perceive themselves as suffering from food allergy but only 1-2% of adults have genuine food allergies. The most common culprits are peanuts, milk, eggs, soy and shellfish. Maintain a food diary and note down and monitor your symptoms. This may help to track your symptoms. Regards.
