Galactosemia is sometimes confused with lactose intolerance, but galactosemia is a more serious condition. Lactose intolerant individuals have an acquired or inherited shortage of the enzyme lactase, and experience abdominal pains after ingesting dairy products, but no long-term effects. In contrast, a galactosemic individual who consumes ...
When lactose intolerance is due to secondary lactase deficiency, treatment of the underlying disease may allow lactase activity to return to normal levels. [6] In people with celiac disease, lactose intolerance normally reverts or improves several months after starting a gluten-free diet, but temporary dietary restriction of lactose may be needed.
While awaiting confirmatory testing for classic galactosemia, the infant is typically fed a soy-based formula, as human and cow milk contains galactose as a component of lactose. [4] Confirmatory testing would include measurement of enzyme activity in red blood cells, determination of Gal-1-P levels in the blood, and mutation testing.
All in all, dairy products can make great treats for dogs who aren't lactose intolerant. The canine diet doesn't rely on dairy, however, so those who can't consume milk truly aren't missing out!
The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase. The latter is produced by the lac operon in Escherichia coli. [12] In nature, lactose is found primarily in milk and milk products. Consequently, various food products made with dairy-derived ingredients can contain lactose. [13]
An example is lactose intolerance. Carbohydrates account for a major portion of the human diet. These carbohydrates are composed of three principal monosaccharides: glucose, fructose and galactose; in addition glycogen is the storage form of carbohydrates in humans.
One of the ingredients is milk, which, since many adult cats are lactose intolerant, can cause diarrhea—or at least loose stools. ... so avoiding fatty foods is recommended (2).
[3] [4] [8] [7] [9] [11] A couple of diets suggest specific lactose-free products for the lactose intolerant, such as soy milk or whipped cream. [ 5 ] [ 6 ] One diet prohibits whole milk, half and half , cream, sour cream, and regular ice cream.
