Human Nutrition

The human body is an amazing example of millions of years of evolution, although delicate the human body endures a lot of stress and strain in everyday life some more than others and whether or not it can withstand these pressures of day to day life is entirely up to the fuel it receives and runs on, also of course genetics play a major role also upon us as human beings and our general overall well being, proper nutrition plays a very important roll here in all of the above.
The lack of just one vital mineral or vitamin can have adverse effects on the whole "vehicle" and how it runs, as I see the human body as a "vehicle" simply a mode of transport, what is important is what is under the bonnet! There is one element that is always overlooked when talking nutrition and that is water (macro nutrient) the human body is made up of 60-75% of it, water carries life energy pretty much it is our lifeline as you know without a good pollution free supply of it we are pretty much good as dead! Good nutrition to maintain and understand good healthy nutrition is not that hard, in a nutshell basically broken down into "Macro nutrients" and "Micro nutrients" Macro nutrients are the nutrients that are required in large quantities such as your vitamins and minerals, fats and carbohydrates, Micro nutrients (small) are the minerals such as manganese, zinc, chromium, iron, iodine etc these are only needed in small quantities usually less than 100micrograms/day or so.
Iodine..

every time I hear that mineral mentioned I think of a very interesting documentary I watched on the effects of iodine deficiency that usually occurs in third world countries (but not in all cases) I seen some years back and is a classic example of how important it is to maintain ones "Micro nutrients" as the effects of iodine deficiency is quite dramatic the result being mental retardation and brain damage, the interesting bit about this is it is related to topography so the higher up you are the more iodine depleted soil there is the more chance you have of missing out on this very important mineral, I find this fascinating, iodine is found in decent levels in most seafood's and usually slots itself into ones diet eating this group of foods as it is only needed in small amounts.
Carbohydrates: These are broken into different groups, your Mono saccharides and Poly saccharides to explain these would be very involved plus I would be "plagiarizing" as I really do not know the full biochemical process slots itself into the human diet, what I do know is they are important in converting sugar into the energy, proper brain function and muscle energy (fuel) is dependent on this energy source I learnt this back when I was younger and into body building and treated my body as a temple, then we get older right? Remember sugar is 100% carbohydrate, it's like anything to much is no good! The simple carbs and complex carbs, sugar is evil but it plays a fairly major role in our bodies nutrition.
