Crohns Disease:
Crohn's disease is an ongoing disorder that causes inflammation of the digestive tract, also referred to as the gastrointestinal (GI) tract. Crohn's disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly affects the lower part of the small intestine, called the ileum. The swelling extends deep into the lining of the affected organ. The swelling can cause pain and can make the intestines empty frequently, resulting in diarrhea.

Celiac Disease:
Celiac disease, also known as gluten intolerance, is a genetic disorder that affects 1 in 1331 Americans. Symptoms of celiac disease can range from the classic features, such as diarrhea, weight loss, and malnutrition, to latent symptoms such as isolated nutrient deficiencies but no gastrointestinal symptoms. The disease mostly affects people of European (especially Northern European) descent, but recent studies show that it also affects Hispanic, Black and Asian populations as well1. Those affected suffer damage to the villi (shortening and villous flattening) in the lamina propria and crypt regions of their intestines when they eat specific food-grain antigens (toxic amino acid sequences) that are found in wheat, rye, and barley3. Oats have traditionally been considered to be toxic to celiacs, but recent scientific studies have shown otherwise. This research is ongoing, however, and it may be too early to draw solid conclusions.

Lactose intolerance
Lactose intolerance is the inability to digest significant amounts of lactose, the major sugar found in milk. Lactose intolerance is caused by a shortage of the enzyme lactase, which is produced by the cells that line the small intestine. Lactase breaks down milk sugar into two simpler forms of sugar called glucose and galactose, which are then absorbed into the bloodstream. Not all people deficient in lactase have the symptoms commonly associated with lactose intolerance, but those who do are said to have lactose intolerance.
