Fats
a class of energy-giving nutrients and are the main form in which energy is stored in the body
Proteins
are a class of energy-giving nutrients made up of amino acids, which are needed to build and repair body structures and to regulate processes in the body.
Vitamins

Minerals
are a class of nutrients that are chemical elements that are needed for certain processes, such as enzyme activity and bone formation.
Water
makes up 60% of your body and is essential because it is necessary for almost every function that keeps you alive.
Balanced Diet
have a healthy diet and eat what is right for your body
Metabolism
sum of the chemical processes that take place in your body to keep you alive and active
Carbohydrates
a class of energy-giving nutrients that includes sugars, starches, and fiber
Starches
a type of complex carbohydrates, which are made of many sugars that are connected together. ?? eaten in food is broken down by the body into sugars that can be used by the body.
Glycogen
body’s quick energy reserve. It is made of highly branched chains of glucose units to be used by body cells
Fiber
type of complex carbohydrates that provides little energy and cannot be digested by humans and is extremely important to your health.
Fats
the class of energy-giving nutrients; also the main form of energy storage in the body. Belongs to a class of chemical compounds called lipids which are fatty or oily substances that don’t dissolve in water.
Saturated Fats
some fatty acids that are made up of a change of carbon atoms with single bonds between each other. Each carbon atom us said to be ? because it is bonded to as a many hydrogen atoms as is chemically possible. are fats that are made up of ? fatty acids.
Unsaturated Fats
some fatty acids are made up of a chain of carbon atoms with one or more double bonds between the carbon atoms. They are fats that are made up of ??
acids.
Cholesterol
another type of lipid; found in all human and animal tissues. It is needed to make vitamin D, cell membranes certain hormones and bile.
Proteins
your muscles, skin, hair, and nails are made up of mostly ?. ? in the body help build new cells and repair existing ones. ? are made up of chains of molecules called amino acids.
Complete Proteins
animal proteins such as meat, eggs, and dairy products contain all the essential amino acids.
Incomplete Proteins
most plant proteins found in foods such as legumes, grains, and vegetables have smaller amounts of some essential amino acids than your body needs.
Vitamins
Class of nutrients that contain carbon and are needed in small amounts to maintain health and allow growth.
Fat Soluble Vitamins
include vitamins A, D, E and K because they dissolve in fat and most can be stored in fat tissue and remain in the body for a long time.
Water Soluble Vitamins
unlike fat-soluble vitamins, most ??
are not stored in the body very well. Although the B vitamins do not provide energy; most of them are needed to release energy from carbohydrates, fats, and proteins.
Minerals
Class of nutrients that are chemical elements that are needed for certain processes such as enzyme activity and bone formation
Balanced Diet
to be healthy you need the right amount of nutrients from each class
Nutrient Deficiency
the state of not having enough of a nutrient to maintain good health. For most of us a balanced diet can meet all of our vitamin and minerals
Sodium
need for the regulation of water balance in cells and tissues and for transmission of nerve impulses
Calcium
needed for development and maintenance of bones and teeth, transmission of nerve impulses, muscle contraction, and blood clotting
Iron Deficiency
(anemia) is one of the most common nutritional deficiencies in the world. Is a condition in which there are not enough red blood cells or hemoglobin to carry oxygen around the body.
Water
is essential because it is necessary for almost every function that keeps you alive.
RDA
(recommened dietary allowances) the recommended nutrient intakes that will meet the needs of almost all healthy people. They are not exact requirements but are meant to serve for the general public.
Calories
the label must list total calories and the calories from fat in a serving of the food. Any food that has more than 400 calories per serving is considered to be high in calories
DV
recommended daily amounts of nutrients
Additives
substances added to foods to keep the foods from spoiling or improve taste, smell, texture, appearance, or nutrient content of a food
MyPyramid
food guidance system is a tool that can help you choose what to eat and how much to eat every day. Shows 6 colored stripes each are representing a different food group.
Nutrient Density
measure of the nutrients in a food compared with the energy the food provides.
Vegetarian Diet
a diet in which few or no animal products are eaten.
Vegans
the strictest vegetarians that do not eat any animal products are vegetarians that eat no animal products in any form
metabolism
sum of the chemical processes that take place in your body to keep you alive and active
