15/10/2005 - Real apple cider vinegar is a natural substance, but only if from a bio farm. It strengthens the immune system, as it is an excellent source of trace and micro elements. However, this is only true of vinegar derived from apples grown in a natural (e.g. grassy) environment free of fertilisers and insecticides. An apple that is artificially cultivated does not undergo real ripening, and so does not contain the biologically complete stock of micro elements of which it is genetically capable.
15/10/2005 - Bacteria are single-cell creatures that are invisible to the naked eye. Their size varies from 0.1 to 10 microns (1 millimetre = 1,000 microns). Their structure varies from the simple to the complicated – for example, some do not even have a cell wall. For our purposes, we distinguish beneficial and pathogenic bacteria, though this classification is arbitrary and not necessarily precise. For example, some types of bacteria are largely beneficial or neutral for pigeons, but in certain conditions can still become pathogens.
