’’A person’s reason for doing someone a good turn matters as much as the good turn itself.’’ - The Neverending Story
If you understand Spanish and have access to RTVE videos, I recommend a video from Órbita Laika called “Lactasa e intolerancia a la lactosa.”
To summarise, it explains that lactose-free milk does contain lactose, but lactase has been added to it. Lactose is a “double sugar” made up of glucose and galactose, and lactase breaks it down into those two sugars so that your body can digest them and use them for energy. The intestines of people who can normally drink milk produce lactase. If they can't produce enough lactase, it causes lactose intolerance.
If other dairy products don't affect you that much, you could try goat's milk for a while. It contains slightly less lactose, which isn't significant in terms of lactose intolerance, but some people find it easier to digest because it has a different composition. However, it is more expensive and might not be available in some places.
As most of the sugar in dairy products is lactose, you can see how much lactose a dairy product contains by looking at the “Carbohydrate, of which sugars” section in the nutritional information table, as long as the ingredients list doesn't mention any added sugars.
Hope this helps!
Hala, primera noticia de que hay un programa de ciencia en la RTVE, y pinta divertido!

Vale, he visto el video y ha sido súper ilustrativo. Ahora lo tengo todo claro.

En cuanto a la leche de cabra, me gusta tanto que cuando la compro quiero beberla sola para disfrutarla bien. No sé si tendría el valor de usarla para cafés y batidos.

Muchas gracias por tu aporte. Me ha ayudado un montón!
