Nutrition and Diet

What is nutrition?

Nutrition -  Is the organic process  of  nourishing  or  being nourished; the processes  by  which  an  organism, including plant or animal, assimilates food and uses  it  for growth and maintenance.

Why does it matter?

Nutrition is our fuel source - Our bodies take the food and liquids we provide it and break them down as nutrients. It helps us stave off disease, heal wounds, and provide the energy source for physical activity.

Nutrition and Diet

Calories

Definition: any of several units of heat defined as the amount of heat required to raise the temperature of 1 kilogram of water by 1 degree Celsius (1°C) at a specified temperature. 

Carbohydrates

Definition:  Compounds  of  carbon, oxygen and hydrogen forming  an  important part  of  the diet and contributing mainly energy. They include sugars, starches and celluloses and are structurally classified into three groups ”monosaccharides, disaccharides and polysaccharides. Starches and celluloses are polysaccharides.

Protien

Definition: any of a group of complex organic compounds containing carbon, hydrogen, oxygen, nitrogen, and sulfur. Proteins, the principal constituents of the protoplasm of all cells, are of high molecular weight and consist of amino acids joined by peptide linkages. 

Fats

Definition: Also known  as  lipids, fats are stored  as  an  oily liquid under the skin and  in  the abdomen  in  thin-walled cells. Fats form the body's main energy store and are converted into fuel  as  required. Fat stores also form  an  insulant against heat loss,  a  mechanical shock absorber and  a  contouring element.

Fiber

Definition: that portion  of  ingested foodstuffs that cannot  be  broken down  by  intestinal enzymes and juices and, therefore, passes through the small intestine and colon undigested.  It  is  composed of cellulose (which  is  the skeleton of plants), hemicellulose, gums, lignin, pectin, and other carbohydrates indigestible by humans. 

Vitamins and Antioxidants

Definition: defend body cells against oxidative stress. Increased cellular concentrations of antioxidants have been claimed to diminish exercise-induced muscle damage, thus reducing the risk of cellular injury. 

Minerals and fluids

Definition:  inorganic substances which are obtained  in  a  well-balanced diet.  Minerals are essential  in  all metabolic processes, from maintenance  of  cell volume and structure  to  muscle contraction and relaxation, regulation  of  acid-base equilibrium, protection from oxidative stress, bone metabolism, immune function and hemoglobin synthesis. 

Wholesome Balance

Wholesome Balance is managing the key aspects of nutrition, particularly through the increase consumption of whole plant based food, such as fresh fruits and vegetables. In addition, balancing nutrition with other aspects of wellness, including exercise and rest, enable the maximum benefit of good nutrition.
