Acidophilus, also known as *Lactobacillus acidophilus*, is a type of bacteria that is considered beneficial to human health. It's a common ingredient in yogurt and other fermented foods.

Here's what acidophilus eats:

* Sugars: Acidophilus primarily feeds on sugars, particularly lactose (the sugar found in milk).

* Prebiotics: These are non-digestible carbohydrates that act as food for beneficial bacteria in the gut, including acidophilus. Examples include inulin, fructans, and galacto-oligosaccharides.

Here's what acidophilus doesn't eat:

* Proteins: Acidophilus can't break down proteins.

* Fats: Acidophilus can't break down fats.

Important Note: Acidophilus is a beneficial bacteria that lives in our gut and helps maintain a healthy digestive system. It's not a separate organism that needs to be fed with special food.
