Menu 3.1. ascorbic acid

Another supplement served in the restaurant is ascorbic acid, which should be looked upon more in terms of a food-stuff necessary for life, rather than a dietary supplement, since the reason why we need it so bad is a genetic disorder common to all living humans and also apes. It is served as a crystalline white powder dissolved in fresh water, c:a 15g per liter for good taste. Some of the extensive background-information available on the internet about the importance of ascorbic acid for overall good health can be found here:

Menu 3. Supplements, cod liver oil

Dietary supplements are also available from the menu, since eating food is very much about keeping good health in order...these supplements provide necessary "vitamins", "minerals" and other health-promoting stuff, and the first on this list is Cod liver oil. This has a slightly "fishy" taste to it, and can take some time to develop a taste for, but is a convenient way of providing the fat-soluble vitamins A, D and E, out of which vitamin D is actually not a vitamin at all, but a hormone, since it performs it´s action on the cells DNA-structure.
The reason for, and importance of having Natures Restaurant serving Cod liver oil is that with too little vitamin A in one´s body, one might develop problems with one´s eyes, to the point of even going blind, see:

with too little vitamin E in one´s body, one might develop a whole range of different diseases, since vitamin E is the collective name for eight different fatsoluble antioxidants situated in fatty tissue in the body, for example in all cell-walls, protecting them from disintegrating, see:

and with too little of the vitamin/hormone D in one´s body....well, rickets is just one of a number of potential outcomes, see:

although being outside in the sun probably goes a long way to take care of one´s needs...
