Which sugar is commonly found in yogurt?

• A. Glucose
• B. Lactose
• C. Fructose
• D. Sucrose

Answer: (B)

Lactose is the sugar found in milk, and yogurt is made from milk, so the sugar you typically find in yogurt is lactose. During fermentation, the bacteria convert some lactose into lactic acid, which gives yogurt its tang and thicker texture, but the natural sugar present remains lactose for the most part unless the product is labeled lactose-free. Other sugars like glucose, fructose, or sucrose aren’t inherent to milk-based yogurt; they may appear only if flavors or added sweeteners are included. So lactose is the correct choice because it’s the sugar that comes from milk, the base ingredient of yogurt.
