Ever wondered what the difference between a food allergy and a food sensitivity is? Neha Shah, MPH, RD, CNSC, a registered dietician at the Stanford Digestive Health Center, sheds some light in a new video.
In people with food allergies, she explains, the immune system responds to the presence of the food, which isn’t the case for food sensitivities. People with food allergies have to avoid the culprit foods entirely, whereas people with food sensitivities can sometimes have small amounts of the food - though they must figure out what their threshold is. (Too much and the offending food might set off other symptoms like gas, bloating or diarrhea.) Shah uses lactose intolerance as an example of a very common food sensitivity and describes how people can understand their threshold.
