Health Topic Pages

  • Diet: Topic Page
    A planned or prescribed selection of food and drink, especially one designed for weight loss, maintenance of good health or the control of a medical disorder.
  • Exercise: Topic Page
    Exercise is commonly associated with aerobic activity or sustained activity over a period of time that utilizes and strengthens the cardiovascular and pulmonary systems.
  • Metabolism: Topic Page
    Sum of all biochemical processes involved in life. Two subcategories of metabolism are anabolism, the building up of complex organic molecules from simpler precursors, and catabolism, the breakdown of complex substances into simpler molecules, often accompanied by the release of energy.
  • Malnutrition: Topic Page
    Condition resulting from a defective diet where certain important food nutrients (such as proteins, vitamins, or carbohydrates) are absent. It can lead to deficiency diseases. A related problem is undernourishment.

Topic Pages - Nutrients and their Components

  • Water: Topic Page
    Chemical compound of hydrogen and oxygen elements - H2O. MORE
  • Fat: Topic Page
    In the broadest sense, a mixture of lipids - chiefly triglycerides (lipids containing three fatty acid molecules linked to a molecule of glycerol). MORE
  • Carbohydrate: Topic Page
    Any of a group of organic compounds, present in the cells of all living organisms, which consist of carbon, hydrogen and oxygen and are formed in green plants during photosynthesis. MORE
  • Protein: Topic Page
    Any of thousands of different organic compounds, characteristic of all living organisms, that have large molecules consisting of long chains of amino acids. MORE
  • Vitamin: Topic Page
    Any of various organic compounds that occur in small amounts in many foods, are also manufactured synthetically and are essential in small amounts for the normal growth and functioning of the body. Only the B complex and vitamin C are water-soluble and hence are excreted, requiring regular replacement. MORE
  • Mineral: Topic Page
    Any inorganic substance, ie one that is neither animal nor vegetable. MORE
  • Calorie: Topic Page
    Abbr. cal, unit of heat energy in the metric system. MORE
  • Sugar: Topic Page
    Sweet, soluble, crystalline carbohydrate found in the pith of sugar cane and in sugar beet. MORE
  • Starch: Topic Page
    White, odorless, tasteless, carbohydrate powder. MORE
  • Salt: Topic Page
    Any salt in which the positive ion (onium ion) is formed by the attachment of a proton to a neutral compound, as in ammonium, oxonium, and sulphonium compounds. MORE
  • Calcium: Topic Page
    (abbreviation Ca, atomic number 20) a soft, silvery-white metallic element which occurs mainly in the form of calcium carbonate minerals such as chalk, limestone and marble, and which is an important constituent of bones, teeth, milk and plant cell walls. MORE
  • Iron: Topic Page
    a malleable ductile silvery-white ferromagnetic metallic element occurring principally in haematite and magnetite. It is widely used for structural and engineering purposes. MORE
  • Sodium: Topic Page
    (symbol Na, atomic number 11) a soft silvery-white metallic element used in alloys, as a reducing agent in chemical reactions, as a coolant in nuclear reactors, and in non-glare lighting, eg in street lamps, and also widely used in the form of its compounds, especially sodium chloride, in the chemical industry. MORE
  • Potassium: Topic Page
    (symbol K, atomic number 19) a soft silvery-white metallic element, compounds of which are used in fertilizers, explosives, laboratory reagents, soaps and some types of glass. MORE
  • Magnesium: Topic Page
    (symbol Mg, atomic number 12) a reactive silvery-grey metallic element that burns with a dazzling white flame, used in fireworks and in strong light alloys for aircraft components, etc. It is also an essential trace element in plants and animals. MORE
  • Zinc: Topic Page
    (symbol Zn, atomic number 30) a brittle bluish-white metallic element used in dry batteries and various alloys, and as a corrosion-resistant coating to galvanize steel. MORE
