Food intolerance can cause a range of gut and systemic symptoms [1]. The possibility that these conditions might be caused by intolerance to lactose has often been missed because it is not generally appreciated how widely lactose is used as a food additive: the addition of lactose to manufactured foods and drinks is not necessarily mentioned on the package label. Lactose has about one sixth of ...

AIM Lactose and complex carbohydrates maldigestion, common food intolerances due to low gut content of α- and β-galactosidase, lead to abdominal symptoms including pain, diarrhea, bloating, flatulence, and cramping. Commonly, intolerant patients are advised by physicians to avoid the offending foods (dairy foods, cereals, beans, etc). This food-limiting option, however, has possible nutritional...

BACKGROUND Adult-type hypolactasia is caused by genetic lactase non-persistence. It is the most common cause of lactose intolerance, which results in gastrointestinal symptoms after ingestion of dairy products. Currently, lactose intolerance is investigated by the hydrogen breath test (HBT), which is considered the preferred diagnostic test. Adult-type hypolactasia may also be diagnosed by geno...

Histamine-induced food intolerance is not IgE-mediated. Skin-prick testing and specific IgE to food allergens are typically negative. Food rich in histamine or red wine may cause allergy-like symptoms such as sneezing, flush, skin itching, diarrhoea and even shortness of breath. The suspected reason is a diminished histamine degradation based on a deficiency of diamine oxidase. As diamine oxida...

BACKGROUND Dairy products have been perceived as having the potential to cause adverse effects in individuals with Crohn's disease (CD) and are often avoided, potentially increasing the risk of osteoporosis and related morbidity associated with inadequate dietary calcium intake. OBJECTIVE To evaluate the self-reported effects of dairy products on CD symptoms and to determine whether these eff...

When this disorder is properly diagnosed, the patient is easily treated with education and dietary modifications. Lactose intolerance is commonly misdiagnosed because of its overlapping symptoms of diarrhea and abdominal bloating. This article revi...
