The most effective way to take in adequate amounts of nutrients is to eat a balanced diet. Well balanced diet should include a wide variety of foods from four different food groups and other foods:

An infection is the detrimental colonization of a host organism by a foreign species. The colonizing organism interferes with the normal functioning and perhaps the survival of the host. The infecting organism is referred to as a pathogen, which may be bacterial, a parasite, fungal, or a virus, prion or viroid. The scientific study of diseases in medicine caused by biological agents is infectious diseases.

All multicellular organisms are colonized to some degree by extrinsic organisms, and the vast majority of these exist in either a symbiotic, commensal, or parasitic relationship with the host. An example of the former would be the anaerobic bacteria species which colonize the mammalian colon, an example of the latter would be the various species of staphylococcus which exist on human skin. Neither of these colonizations would be considered infections.

An infection is, in effect, a war in which the infecting organism seeks to utilize the host resources in order to multiply at the expense of the host.

The difference between an infection and a colonization is often only a matter of circumstance. Organisms which are normally non-pathogenic can become pathogenic under the right conditions, and even the most virulent organism requires certain circumstances to cause a compromising infection. More...
