The nourishment needed by living things to sustain life.
The building blocks of life are nutrients, and humans can utilize the following nutrients -
'Carbohydrate': most commonly found as complex carbohydrate as starch in bread, pasta and potatoes; and as simple carbohydrate in sugar, sucrose and honey. The complex versions give long lasting, rather than short-bursts of energy.
'Protein': found in eggs, fish, meat, milk, nuts and some vegetables. Essential for muscle-building.
'Fat': found in most animal products, butter, fish, margarine, milk, nuts and oils. A certain amount of fat is essential in our diets, and as it takes longer for our bodies to digest, gives sustained energy if taken with complex carbohydrates.
'Vitamins': a number of chemically unrelated organic compounds that are necessary in minute quantities for the normal functioning of the human body. See vitamins
'Minerals': found in a wide variety of foods; a good source of calcium is milk; of iodine seafood; of iron liver and green vegetables etc. See "Candolle, Alphose de"; 'Carbohydrate'; "Fabre, Jean Henri Casimir"; 'Fat'; "Minerals"; 'Protein'; 'Vitamins'
