This makes it to take time before occurring and one can present symptoms after about four hours while others are delayed up to day two after ingesting the meal due to differences in  immunity among  individuals.

Food intolerance is thus a pathological response that is tough even for medics to determine the nutrients that elicit various reactions in one‘s body. Without taking thorough history or using shortcuts one is likely to misdiagnose it with its differentials where the leading is food allergy, malaria and sepsis of the body system. In this condition good history of presenting illness, review of system and physical examination is needed.
