**Carbohydrates** are the nutrient that gives energy to our body. They are one of the three main macronutrients, along with proteins and fats, that are essential for our body's function and growth. Carbohydrates are the primary source of energy for our body, providing us with fuel to carry out our daily activities.

**Explanation:**

**1. What are Carbohydrates?**
Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen atoms. They are found in a variety of foods, including grains, fruits, vegetables, legumes, and dairy products. Carbohydrates come in different forms, such as sugars, starches, and fibers.

**2. How do Carbohydrates provide energy?**
When we consume carbohydrates in our diet, our body breaks them down into glucose, which is a simple sugar. Glucose is then transported through the bloodstream to our cells, where it is used as a source of energy. Our body's cells convert glucose into ATP (adenosine triphosphate), which is the molecule responsible for storing and releasing energy.

**3. Importance of Carbohydrates as an energy source**
Carbohydrates are the body's preferred source of energy because they can be quickly broken down and used by our cells. They provide a readily available and efficient fuel source for our muscles, brain, and other organs. Without an adequate intake of carbohydrates, our body may not have enough energy to function properly.

**4. Recommended intake of Carbohydrates**
The recommended daily intake of carbohydrates varies depending on factors such as age, sex, activity level, and overall health. In general, carbohydrates should make up around 45-65% of our total daily calorie intake. It is important to choose healthy sources of carbohydrates, such as whole grains, fruits, vegetables, and legumes, which also provide essential vitamins, minerals, and fibers.

In conclusion, **carbohydrates are the nutrient that gives energy to our body**. They are an essential part of our diet and provide us with the fuel needed to carry out our daily activities. It is important to include a variety of healthy carbohydrates in our diet to ensure we meet our body's energy needs and maintain overall health.
