Filter by:There is increasing evidence that a number of people experience moderate milk intolerance characterised by increased gas production, bloating and abdominal cramp, which can neither be attributed to lactose intolerance, nor to milk protein allergy. Milk digestion can lead to the formation of bioactive peptides, one of which derived from a mutated gene variant (A1) coding for milk beta-casein has been associated with increased gastrointestinal inflammation and poor gastrointestinal function. In this study, we hypothesise that consumption of non-mutated A2 milk will improve gastrointestinal symptoms in non-lactose milk intolerant individuals.
In the last few years a new clinical entity has emerged which includes patients who consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease (CD) or wheat allergy. This clinical condition has been named non-celiac gluten sensitivity (NCGS), although in a recent article, the researchers suggested the term "non-celiac wheat sensitivity" (NCWS), because it is not known to date what component of wheat actually causes the symptoms. The clinical picture of NCWS is characterized by combined gastrointestinal (bloating, abdominal pain, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and extra-intestinal or systemic manifestations (headache, depression, anxiety, 'foggy mind,' tiredness, dermatitis or skin rash, fibromyalgia-like joint/muscle pain, leg or arm numbness, and anemia). Lactose intolerance and cow's milk protein allergy (CMPA) are two medical conditions with a very high prevalence in the general population, and there is a large overlap between NCWS symptoms and lactose intolerance and CMPA symptoms. Therefore, the aims of the present study are to investigate 1) the prevalence of positive lactose breath test and DBPC cow's milk protein challenge in NCWS patients with self-reported gastrointestinal symptoms related to milk and/or milk derivates ingestion, 2) the clinical, serological, and histological characteristics of NCWS patients with lactose intolerance and CMPA in comparison to NCWS patients without lactose intolerance and CMPA.
This study is designed to assess the effect of a new PPARgamma modulator on the expression and activity of the lactase enzyme in human intestinal epithelial cells. Based on their previous experimental results, the investigators hypothesized that modulating intestinal PPARgamma activity is a new pharmacological mechanism allowing the control of lactase expression and activity in the gut
This is a 3-sites, double-blinded, randomized, 2X2 cross-over study aiming to compare effects of milk containing only A2 type beta casein versus milk containing both A1 and A2 beta casein proteins on the gastrointestinal symptoms for the health people who self-reported to be lactose intolerant.
Milk is the source of high-quality protein, calcium, and other vitamins and minerals. Epidemiologic studies have linked high consumption of milk with risk of metabolic syndrome, T2DM, hypertension and obesity, which are independent risk factors of cardiovascular disease. However, milk contains disaccharide lactose, which may cause gastrointestinal problems in those adults with poor digestion. Recent studies have shown that subjects with intolerance to lactose tend to reduce their consumption of milk. Actually, consumption of 12g lactose (240ml milk) per day produces negligible symptoms in lactose intolerant. Furthermore, a dairy-rich diet could improve lactose intolerance because of colonic adaption to it. Lactose maldigestion would not be a restricting factor in milk intake. In general, the undigested lactose will be fermented by colonic bacteria into hydrogen, carbon dioxide, and short-chain fatty acids (SCFA: acetate, propionate, and butyrate). The SCFAs may have beneficial effects on human glucose and lipid metabolism, and the lactose fermentation may change the intestinal flora profile. But there are few studies evaluating effect of milk intake on health of people with lactose malabsorption or intolerance.This trial intend to study the effect of whole milk on cardio-metabolic risk factors of healthy person with or without lactose maldigestion.
The purpose of this study is to investigate the effect of a fermented infant formula on lactose digestion in lactose intolerant adults.
RP-G28 is being investigated for treatment of moderate to severe lactose intolerance and its potential to improve the tolerance of lactose (dairy products).
The purpose of this study is to evaluate both the impact of LacTEST on diagnostic thinking and on patient management, and its reproducibility (Test-Retest), for the diagnosis of hypolactasia in adults and elderly patients presenting with clinical symptoms of lactose intolerance.
The purpose of this study is to assess that two β-galactosidase Producing Probiotic Strains help improve lactose digestion in subjects with lactose maldigestion.
This is a single-site, double-blinded, randomized, controlled, 2X2 cross-over study aiming to compare effects of milk containing only A2 type beta casein versus milk containing both A1 and A2 beta casein proteins on the gastrointestinal physiology, symptoms and cognitive behaviour for the health people who are intolerant to traditional cow's milk.
