Educational worksheet focusing on identifying main ideas and details in a passage about Vitamin D.

- Main Idea: Vitamin D is a very important vitamin that helps build strong bones, supports the immune system, strengthens the heart, and plays other health roles; many people are lacking it due to limited sun exposure and dietary sources.
- Detail 1: People are exposed to less sunlight now because they use sunscreen to protect their skin, which reduces the body’s natural production of Vitamin D.
- Detail 2: Many foods like milk, cereals, and yogurt are fortified with Vitamin D, meaning it is added to help people meet their daily needs.
- Detail 3: Naturally occurring Vitamin D can be found in foods such as fish, egg yolks, and mushrooms, but these are not commonly eaten by many children today.
