what are nutritions
Answers
Answer:
Nutrition
Have you ever heard the expression, 'you are what you eat?' While we can't take this literally, this simple saying contains a lot of truth.
The foods you choose to eat determine which nutrients your body will receive and in what quantities. Nutrients are substances that allow your body to make energy, build and maintain tissues, and regulate bodily processes. If you eat a healthy diet filled with a variety of high-nutrient foods, you are more likely to enjoy good health than if you eat a poor diet that is lacking in nutrients. This lesson will provide an overview of nutrition, which is the process of taking in nutrients from foods, by looking at the six classes of nutrients:
Carbohydrates
Lipids
Proteins
Water
Vitamins
Minerals
Macronutrients
Three of these six classes of nutrients are referred to as macronutrients because they are required in large quantities. The prefix macro means large, so this is a fairly easy term to remember.
The macronutrients are carbohydrates, lipids and proteins. They are somewhat unique because they are the only nutrients that provide your body with energy, which is measured in calories.
Of the three macronutrients, your body looks to carbohydrates for quick energy because carbs are readily available when there's an immediate need for energy. All carbohydrates come from food, but different foods contain different types of carbohydrates. For example, when you eat a cookie, you are consuming mostly sugars, or simple carbs, whereas your spaghetti dinner contains a lot of starches, which are complex carbs made up of many sugars. Eat some fruits and veggies and you will take in fiber, which is a type of carbohydrate that cannot be digested. This means you cannot get energy from fiber, yet fiber is great for moving foods through your digestive tract, so you want plenty of it in your diet.
