Galaktózforrások refers to the sources from which galactose can be obtained. Galactose is a monosaccharide, a simple sugar, that plays a role in various biological processes. While it can be synthesized in the body, dietary sources are also important for obtaining galactose.

The primary dietary source of galactose is lactose, the sugar found in milk and dairy products. Lactose is a disaccharide composed of one molecule of glucose and one molecule of galactose. When lactose is digested, it is broken down into its constituent monosaccharides, which are then absorbed by the body. Therefore, milk, cheese, yogurt, and other dairy products are significant sources of dietary galactose.

Beyond dairy, free galactose is less commonly found in significant amounts in other foods. Some fruits and vegetables contain small quantities of galactose as part of more complex carbohydrate structures, such as pectins and gums. However, these amounts are generally much lower compared to the galactose derived from lactose digestion. Certain fermented foods may also contain small amounts of galactose, depending on the fermentation process and the initial substrates used.

In some specialized contexts, galactose can be obtained through the breakdown of other complex carbohydrates or through specific metabolic pathways. However, for most individuals, the consumption of dairy products remains the most readily available and significant source of dietary galactose. The body can also convert other sugars, like glucose, into galactose if needed, indicating a degree of metabolic flexibility in galactose availability.
