IntroductionIntroduction
Nutrition is the science of nourishing the body properly to reach higher levels of dynamic living.
You can provide yourself with the six nutrients in a well rounded, diversified diet.
By reading labels and choosing your food carefully, you can maintain a lean body, free from excess personal fat.

Diets have radically changed in the last 35 years.
Proper eating habits now take a back seat to convenience and lack of time.

The first three ingredients, carbohydrates, fats, and proteins, are foodstuffs. They give us energy for body processes.
The released energy is measured in calories.

CarbohydratesCarbohydrates
Carbohydrates are found in fruits, grains, and vegetables.
With a value of 4 calories per gram, they supply short- and long-term energy for everything from thinking to breathing to running a race.

Short-term carbohydrates are the sugars, or simple carbohydrates, that are quickly absorbed.
Short-term carbohydrates are the sugars, or simple carbohydrates, that are quickly absorbed.
Glucose (blood sugar) is the most important simple sugar. Many sugary foods (candy, soda) are sources but contain few nutrients.
Fruit is an excellent source of simple carbohydrates and has vitamins and minerals as well.

Nourishing Your Body’s Fuel with FatsNourishing Your Body’s Fuel with Fats
Fats (lipids) maintain body temperature, insulate body organs, provide stored energy, and carry fat-soluble vitamins(A, D, E, & K) to the cells.
One gram of fat is equivalent to 9 calories of energy, more than twice the equivalent of carbohydrates (1 gram = 4 calories).
The most sensible approach to maintaining a lean level of body fat is to minimize your fat intake.

Your liver already produces about 1,000 milligrams (mg) of cholesterol daily, and diet adds another 400 to 500 mg.
Cholesterol, a waxy, sticky substance found in animal and human waste tissue, insulates nerves and forms hormones, cell membranes, vitamin D, and bile to aid in food digestion.

Your blood carries cholesterol by way of lipoproteins, with low density lipoproteins (LDL) carrying cholesterol that is not needed by the cells in the arteries, giving them the nickname of the “bad guys.”
Cholesterol accumulated on the inside walls of the arteries is a factor in the development of atherosclerosis. Eventually, cardiovascular disease, in the form of a heart attack or stroke, may result.

The high density lipoproteins (HDL) carry the extra cholesterol in your blood to the liver to dispose of it, thus preventing cholesterol from building up in the arteries. For this reason, HDLs are known as the “good guys.”
To keep cholesterol at a normal level in the body, you must lower LDL levels and raise HDL levels.

Steps you can take to accomplish this are to eat less fat, especially saturated fat, maintain appropriate body weight, and participate in a regular exercise program.
Eating more fiber will also help because it binds with cholesterol and carries it out of the body; and consuming monounsaturated fats, such as olive oil, canola, and peanut oils, raises HDLs.

ConclusionConclusionUnderstanding your body’s nutritional needs is essential to maintaining your physical and emotional health.
Without the proper balance of carbohydrates, fats, proteins, vitamins, and minerals, you open the door to health problems.
Even with a fast-paced lifestyle, you can eat correctly and give your body the fuel it needs to be healthy and active.
