Task 1. Read the text and answer the questions.

Food gives us nutrients. Nutrients help the body do its job. You cannot see nutrients. Yet you cannot live without them.
Protein is the number one nutrient. It helps the body grow. You can get it by eating animals like meat or fish. You can also get it from many plants. Beans and nuts have lots of protein.
Carbohydrates are another nutrient. They give us a lot of energy. You can get them by eating starches. Rice and bread are two examples.
People also need minerals. Calcium is one example. It keeps your bones and teeth strong. Calcium is found in milk and cheese. You can also get it from leafy greens like spinach.
