Which nutrient is NOT typically found in significant amounts in milk?

Milk is considered a nutrient-rich food, providing a variety of essential nutrients that play a vital role in human health. Calcium, vitamin B12, and phosphorus are all found in significant amounts in milk.

Calcium is crucial for building and maintaining strong bones and teeth, making it one of the most notable nutrients in milk. Vitamin B12, which is necessary for red blood cell formation and neurological function, is also densely present in dairy products. Phosphorus works in tandem with calcium for bone health and helps with energy metabolism, also making it a prominent nutrient found in milk.

In contrast, while iron is an essential mineral needed for various bodily functions, including oxygen transport in the blood, it is typically present in milk in very low amounts. Consequently, milk is not a reliable source of iron when compared to other food sources, such as meats, beans, or fortified cereals. Thus, identifying iron as not typically found in significant amounts in milk highlights its limited presence compared to the other mentioned nutrients.
