[citation needed], Plant-based milks and derivatives such as soy milk, rice milk, almond milk, coconut milk, hazelnut milk, oat milk, hemp milk, macadamia nut milk, and peanut milk are inherently lactose-free. A person can have both conditions. Lactose intolerance is a common condition caused by a deficiency of lactase, the enzyme needed to digest the sugar in dairy known as lactose. This is quite safe, but you may need to experiment to find out how much they can comfortably eat or drink. They may be distinguished in diagnosis by giving lactose-free milk, producing no symptoms in the case of lactose intolerance, but the same reaction as to normal milk in the presence of a milk allergy. health information, we will treat all of that information as protected health [9] Populations that raised animals not used for milk tend to have 90100 percent of a lactose intolerant rate. Lactose intolerance is also more common in people of West African, Arab, and Jewish descent, while only about 5 percent of people of European descent are lactose intolerant. It functions well only in high-acid environments, such as that found in the human gut due to the addition of gastric juices from the stomach. These contain the same vitamins and minerals as standard dairy products, but they also have an added enzyme called lactase, which helps digest any lactose so the products do not trigger any symptoms. While there currently isnt a cure for lactose intolerance, you can still manage the symptoms easily at home. About 40 cases have been reported worldwide, mainly limited to Finland. This enzyme, produced by yeast from the genus Kluyveromyces, takes much longer to act, must be thoroughly mixed throughout the product, and is destroyed by even mildly acidic environments. Stool pH in lactose intolerance is less than 5.5. If the lactose cannot be digested, enteric bacteria metabolize it and produce hydrogen, which, along with methane, if produced, can be detected on the patient's breath by a clinical gas chromatograph or compact solid-state detector.

Before the 20th century, babies born with congenital lactase deficiency often did not survive,[2] but death rates decreased with soybean-derived infant formulas and manufactured lactose-free dairy products. As few as 5% of northern Europeans are lactose intolerant, while as many as 90% of adults in parts of Asia are lactose intolerant. [76] Some populations have developed genetic changes to allow the digestion of lactose: lactase persistence. However, if a "D" (for "dairy") is present next to the circled "K", "U", or other hechsher, the food product likely contains milk solids,[60] although it may also simply indicate the product was produced on equipment shared with other products containing milk derivatives.

The bacteria in the colon, mixed with the lactose, cause acidity in stools. [1] Other conditions that may produce similar symptoms include irritable bowel syndrome, celiac disease, and inflammatory bowel disease. [9] The downregulation of lactase expression in mice could be attributed to the accumulation of DNA methylation in the Lct gene and the adjacent Mcm6 gene.

[76], Lactase persistence in humans evolved relatively recently (in the last 10,000 years) among some populations. Hypolactasia is the term specifically for the small intestine producing little or no lactase enzyme. You can have low levels of lactase and still be able to digest milk products.

If you're lactase deficient, lactose in your food moves into the colon instead of being processed and absorbed. [28] These polymorphisms may be detected by molecular biology techniques at the DNA extracted from blood or saliva samples; genetic kits specific for this diagnosis are available. Normally, lactase turns milk sugar into two simple sugars glucose and galactose which are absorbed into the bloodstream through the intestinal lining.
