What is Nutrition? 

In order for human beings to exist, they must provide nourishment to their cells.  This usually occurs through food and drink.   Physical health improves with a healthy diet.  A diet that is lacking in nutrients can have a negative impact on health and lead to a number of ailments including obesity, cardiovascular disease, osteoporosis and diabetes. 

There are six major nutrient classifications: protein, fat, carbohydrates, minerals, vitamins and water.  

Proteins are one of the building blocks of the body, but can also serve as a fuel source.   Proteins are used by the body for growth and maintenance and aside from water, protein is the most abundant molecule in the body.  Examples of food sources of complete protein include meat, eggs and fish.  

Carbohydrates refer to any food that is particularly rich in the complex carbohydrate starch such as cereals, bread and pasta.  Simple carbohydrates are sugars such as those found in jams and candy.  The Institute of Medicine recommends that American and Canadian adults get between 45-65% of dietary energy from carbohydrates.  

Dietary Minerals are required in the daily diet in order to maintain optimal health.  Some examples of these include calcium, magnesium, chromium and iron.  They can be found naturally in foods and all elements can be obtained through healthy eating but many individuals take dietary supplements to enhance their intake of such minerals. 

Water makes up two-thirds of our body weight.  A 2% drop in water supply can trigger signs of dehydration such as fuzzy short-term memory, trouble with basic math and difficulty focusing on smaller print.  It is one of the most common causes of daytime fatigue.
