Food allergies have been increasing over the last decades, in parallel with a general increase of allergy worldwide. however, epidemiological studies on food allergy are difficult to perform (especially when using questionnaires), and contain a number of pitfalls because of a considerable amount of false negative and false positive results. This is mainly because food can induce a number of abn...

1. A questionnaire inquiring about food intolerance was sent to a random sample of the electorate in a small South Wales town. Replies were received from 170 men and 305 women, the response rates being 87 and 93% respectively. 2. Adverse effects of some food were reported by 19% of men and 26% of women, or 14 and 18% respectively if minor digestive symptoms are excluded. Certain foods were thou...

Excessive accumulation of histamine in the body leads to miscellaneous symptoms mediated by its bond to corresponding receptors (H1-H4). Increased concentration of histamine in blood can occur in healthy individuals after ingestion of foods with high contents of histamine, leading to histamine intoxication. In individuals with histamine intolerance (HIT) ingestion of food with normal contents o...

Chronic fatigue syndrome (CFS) is an illness characterized by persistent and relapsing fatigue, often accompanied by numerous symptoms involving various body systems. The etiology of CFS remains unclear; however, a number of recent studies have shown oxidative stress may be involved in its pathogenesis. The role of oxidative stress in CFS is an important area for current and future research as ...

Anorexia nervosa (AN) is associated with gut and non-gut symptoms e.g. orthostatic intolerance and fatigue syndromes. Elsewhere, joint hypermobility has been found in non-anorexic populations who have gut symptoms, orthostatic intolerance or fatigue syndromes. We therefore postulated that joint hypermobility may be a feature of AN.Patients from an inpatient Eating Disorders Unit and their first...

In the national study of health and growth parents' responses to a self completed questionnaire were used to categorize children according to their experience of food intolerance. The heights of the children in each group were then compared. Useful responses to the questions on food intolerance were received for 6813 (85%) children in the sample and measurements of height obtained for 7856 (98%...

BACKGROUND Poor adherence to antihypertensive drug regimens is common and may increase the risk for cardiovascular morbidity and mortality. Adverse effects of the drugs can contribute to poor adherence, but some patients who discontinue several different antihypertensive drugs may misinterpret nonspecific symptoms as adverse effects of the drug because of psychiatric morbidity. We examined the ...

BACKGROUND The term "intolerance" is not mentioned in the World Allergy Organization (WAO) document on allergy nomenclature. "Intolerance" has been used to describe some non-immunological diseases. However, pediatric gastroenterologists mix allergy and intolerance, e.g. by using the term "cow's milk protein allergy/intolerance (CMPA/I)", lumping together all types of mechanisms for not tolerati...
