Lactase persistence is very high among northern Europeans, especially Irish people. Worldwide, most people are lactase non-persistent, [1] and are affected by varying degrees of lactose intolerance as adults. However, lactase persistence and lactose intolerance can overlap.
This resulted in higher frequency of lactase persistence. [79] Lactase persistence became high in regions such as Europe, Scandinavia, the Middle East and Northwestern India. However, most people worldwide remain lactase non-persistent. [9] Populations that raised animals not used for milk tend to have 90–100 percent of a lactose intolerant ...
In most mammals, production of lactase diminishes after infants are weaned from maternal milk. However, 5% to 90% of the human population possess an advantageous autosomal mutation in which lactase production persists after infancy. The geographic distribution of lactase persistence is concordant with areas of high milk intake.
The majority of humans actually follow this protocol as well, and down-regulate lactase production around 3-5 years of age. Interestingly, though, the majority of caucasians, mainly those from northern european background, continue to have elevated lactase activity all the way into adulthood, and so they exhibit “lactase persistence”.
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk.It breaks down the sugar lactose into its component parts, galactose and glucose.
2–3% in infants, [3] declining to 0.6% in adults [10] Milk allergy is an adverse immune reaction to one or more proteins in cow's milk . Symptoms may take hours to days to manifest, with symptoms including atopic dermatitis , inflammation of the esophagus , enteropathy involving the small intestine and proctocolitis involving the rectum and ...
Lactic acidosis is commonly found in people who are unwell, such as those with severe heart and/or lung disease, a severe infection with sepsis, the systemic inflammatory response syndrome due to another cause, severe physical trauma, or severe depletion of body fluids. [3]
Lactose, or milk sugar, is a disaccharide composed of galactose and glucose and has the molecular formula C 12 H 22 O 11.Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars.
