It is chart showing what each vitamin does and how we can get it into our diets. For example, Vitamin A - vital for eye health and repair of body tissues - is found in highest quantities in Cod Liver Oil.
Vitamin D - the sunshine one - can be found in fatty fish and eggs, as well as liver oils, and is important for bones and teeth because it aids the use of calcium.
An interesting exercise to get your mind right onto ideal diet, would be to write a diet diary for a week, and then cross check it with the chart to see what vitamins you are getting enough of, and which you are short of. Compare any signs and symptoms you feel you may be seeing or feeling, with the role of absent vitamins. Then adjust your diet to include more of what you're missing.
