There are many reasons why it is a good idea to take a multivitamin and mineral on a daily basis. You have to first understand that for our body to work well and effectively day after day, year after year, it requires a broad range of nutrients, ideally at optimum levels, so it has all that it requires at its disposal to carry out the myriad tasks needed.
If you consume suboptimal levels of even a few nutrients for a period of time, then the body has to start to prioritise how it uses its resources. Some repair work, or enzyme activity or function may not take place because there are not enough of some nutrients to enable this to happen.
In an ideal world we would all eat a good diet, and that diet would give us optimal amounts of what we need. Sadly, today this is far from the case. Much
of our food is not as nutritious as it once was, due to intensive farming practises and poor management of the soil. This depletion of vital nutrients is extremely high in some cases. In addition to this, some people have problems with their digestion, which leads to poor absorption of what nutrients there are. There is also misunderstanding about how much of each individual nutrient we ideally need each day – many people refer to what is called the RDA or recommended daily amount, which is a guideline amount, set by the government to avoid a deficiency disease. But just avoiding a disease is not good health, and for good health we sometimes need substantially more than the RDA guidelines state. For many people, even trying to achieve the RDA levels is hit and miss, let alone optimum levels.
And then, of course, there is the fact that we are not all the same. We all need different amounts of individual nutrients depending upon where we live, our size and shape and what is going on in our lives at any given moment – are we highly stressed, suffering from an illness, pregnant, have a physical job, ageing, exposed to pollution and chemicals, very active, not so active and so on. The list of variations is endless, and will determine our requirements for optimal health.
