Nutrient Basics

Objective I will identify the six basic nutrient groups I will learn how the basic nutrients comprise the foods I eat

You Are What You Eat Food is your body’s fuel Energy is released from the food and the nutrients are used to build, repair, and maintain body cells.

What is a Nutrient? A nutrient is a chemical substance in food that helps maintain the body. Some provide energy. All help build cells and tissues, regulate bodily processes such as breathing. No single food supplies all the nutrients the body needs to function.

What Are Essential Nutrients? The Building Blocks – Contribute to your body’s healthy functioning 1.Carbohydrates 2.Proteins 3.Fats 4.Vitamins 5.Minerals 6.Water

Chemistry of Nutrition Chemical Elements – Elements: the simplest substances from which all matter is formed – Molecule: the smallest amount of a substance made of 2 or more atoms – Atom: the smallest part of an element that can enter into a chemical reaction – Compound: when atoms of 2 or more elements are bonded together

Chemistry of Nutrients Compounds – Carbohydrates – Fats – Proteins – Vitamins – Water Element – Minerals Oxygen, hydrogen, carbon, nitrogen, sulfur, and cobalt

3 Main Functions of Nutrients Essential nutrients from food are used to: Build and repair body tissue Regulate all body processes Provide energy

Build and Repair Body Tissues Cells are formed with materials that come from food.

Regulate Body Processes Keep body processes running smoothly such as: Circulation of body fluids Acid-base level in the blood Digestion, absorption, and metabolism

Provide Energy To breathe Pump blood Move muscles Provide heat Food is to your body as gasoline is to your car. It is a source of energy for performance. Energy is necessary for all life processes to occur

Energy Chemical reactions that take place in the cells release energy from the nutrients you get from food.

Energy Sources Carbohydrates Protein Fats 2 main: Carbs and Fat Water, Vitamins, and Minerals DO NOT provide energy! They help with metabolism and improve the way food is processed but they don’t actually deliver any energy.

Energy value of food Kilocalorie Amount of heat needed to raise one kilogram of water one degree Celsius. kcal Calorie A unit of measurement that describes how much energy the food delivers to the body when it is digested and metabolized.
