There are many different reasons why you may not tolerate certain foods. This can range from deficiencies in enzyme production or sensitivity to chemicals, bacterial overgrowth related to excess sugar, whilst others are immune responses related to food specific antibodies. If the body has experienced a great deal of stress or prolonged medication the small intestines can be prone to become more permeable or “leaky”. This can mean that the breakdown products in foods can be absorbed through the intestine wall, when it wouldn’t normally be permeable to these particles.
The body can mount an immune reponse known as an IgG antibody response to the protein components. Sometimes the body also cannot digest lactose in dairy products and gluten in grains, which is found in much higher quantities in the modern wheat, than it ever used to be in the ancient grains such as Spelt. We can also have an overgrowth of yeast in the intestines, especially following antibiotic use, which can cause bloating and gas as it ferments with sugars in our diet.
The IgG response causes these immune cells to bind to specific food proteins to form immune complexes in the body, which can accumulate in joints and other organs where they can cause inflammation and a range of different symptoms from headaches, digestive problems, bloating, IBS, itching skin, joint aches and pains, weight gain and low mood.
Many symptoms can be linked to food intolerance which include:
