Dr. Kneessi’s examine the difference between food sensitivities and food allergies. He goes further to explore common health issues associated with food sensitivities as well as common foods related to food sensitivities.
Food Sensitivities and Your Gut
According to the United States Department of Agriculture, it is estimated that over 34 million people in the United States have food sensitivities. These are different from food allergies because with an allergy our bodies are making antibodies against a particular food. Some individuals have symptoms after eating certain foods without producing these same antibodies.
Food sensitivities include many different types of sensitivities which arise from a wide variety of reasons. One popular theory on the pathophysiology is that these sensitivities are developed because of increased intestinal permeability aka “Leaky Gut”. This is a very complex mechanism and please feel free to read more about “leaky gut” here. (insert link)
Food Sensitivities VS Food Allergies
Food sensitivities are different from food allergies. Food sensitivities are not true allergies and traditional allergy test such as IgE RAST blood test or skin prick test will yield negative results. Regarding food allergies; the individual can’t tolerate even a small amount of the “trigger food” without developing symptoms as it only takes a small amount to trigger an immune response. IgE test are easy to perform and very reliable to determine food allergies. Food sensitivity is more common than food allergy and symptoms are less severe and can be delayed up to 48 hours.
Sensitivities to several foods is not uncommon and it can be difficult to decide whether these sensitivities are contributing to chronic disease. There are a number of different methodologies used to help determine a food sensitivity. Dr. Kneessi believes the gold standard is an elimination diet protocol which removes common sensitivities for a period of time and is followed by reintroducing those same foods back into the diet. There are also a few non-IgE mediated test and other test searching for activation of cellular responses available which can be beneficial for some individuals.
