i m allergic to lactose.
[{"role": "system", "content": "Lactose is a disaccharide molecule; a sugar composed of galactose and glucose that is found in milk. Lactose makes up around 2\u20138% of milk (by weight), although the amount varies among species and individuals, and milk with a reduced amount of lactose also exists. It can be extracted from sweet or sour whey. The name comes from ' (gen. '), the Latin word for milk, plus the \"-ose\" ending used to name sugars. It has a formula of CHO and the hydrate formula CHO\u00b7HO, making it an isomer of sucrose. The first crude isolation of lactose, by Italian physician Fabrizio Bartoletti (1576\u20131630), was published in 1633. In 1700, the Venetian pharmacist Lodovico Testi (1640\u20131707) published a booklet of testimonials to the power of milk sugar (\"saccharum lactis\") to relieve, among other ailments, the symptoms of arthritis. In 1715, Testi's procedure for making milk sugar was published by Antonio Vallisneri. Lactose was identified as a sugar in 1780 by Carl Wilhelm Scheele. In 1812, Heinrich Vogel (1778\u20131867) recognized that glucose was a product of hydrolyzing lactose. In 1856, Louis Pasteur crystallized the other component of lactose, galactose. By 1894, Emil Fischer had established the configurations of the component sugars.\n"}, {"role": "assistant", "content": "I'm slightly lactose intolerant, which is basically an allergy to the sugar that is found in dairy products like milk."}, {"role": "user", "content": "I always wondered what that meant.

Then I wouldn't want to eat it so much."}, {"role": "assistant", "content": "I highly doubt that you would like that haha, as most things have a form of sugar in it. Even milk, like you just learned and it isn't well known since most people don't know lactose is a sugar."}, {"role": "user", "content": "Yeah, it would make me want it more probably. I like half and half in my coffee."}, {"role": "assistant", "content": "You could even just use milk in your coffee, since about 2 to 8 percent of it is lactose or sugar so it's quite sweet."}, {"role": "user", "content": "The half and half has a smell or creaminess that makes it better than milk. Not sure what it is. butter fat maybe."}, {"role": "assistant", "content": "I guess they are different levels of sugar, like how lactose can be extracted from whey."}, {"role": "user", "content": "I've heard whey protein for body builders , Not sure if it is separated from the lactose or not"}]
