food sensitivity means that you can bite a food and you're typically going to react to a chemical in that food perhaps a protein but it's mostly a small molecule maybe a sugar maybe a fat maybe a spice uh and with that people can get headaches people can get bloating typical food sensitivity is like lactose intolerance when you drink milk for example one of the sugars in the milk is called lactose and if you don't have an enzyme in your gut and in your body called lactase you can't break down that sugar so that's why people take lactate milk for example um and there are some ethnicities that don't have that enzyme so there is a bunch of people that in a certain population really can't drink cow's milk because of that lactose sugar so that's a food sensitivity people get bloating people get headaches but they're not going to have a fatal reaction highly unlikely
