| *What are minerals ? As simple as it may seem, this question is the first step in examining the role of minerals in nutrition. Webster describes minerals as a solid, crystalline substance (diamond copper, quartz, etc.) not of animal or vegetable origin. Important in this definition is the indication that their origin is not from animal or vegetable source. Minerals for nutritional purpose cannot be synthesized by the body. They must be utilized as natural elements from nature. *Why are minerals important ? The following table shows various systems in the body which utilize minerals. Research is showing that imbalances or deficiencies in mineral nutrition can affect these systems. Immune System...............................................Cu, Zn, Fe, Se Energy Production.................................................Mg, P, Mn Hormone System.................................Fe, Mn, Zn, Cu, Mg, K Vitamin Production............................................................Co Blood Production.........................................................Cu, Fe Enzyme System...........................Zn, Cu, Mn, Mg, Fe, Ca, Mo Skeletal System.....................................Ca, Mg, Zn, Mn, B, P Reproduction.........................................P, Cu, K, Mn, Zn, Mg *Are there antagonisms between minerals that affect nutrition responses ? Yes! Looking at the mineral wheel, wherever a mineral has an arrow pointing to another mineral, interference exists. This is caused by an imbalance of one mineral in relation to the other. The antagonism can cause problemswith mineral utilization.The key here is mineral balance. Not only are the levels of individual minerals important but the ratio of minerals to one another can affect final utilization. *What is BIOAVAILABILITY and why is it important ? One good definition of Bioavailability is the amount of a nutrient ingested that is absorbed and thus available to the body for metabolic use. Bioavailabilty is important because all nutritional intake must be available to various body systems for growth, maintenance of body tissues, reproduction and other performance factors. No matter how high the nutrient levels or how well formulated the product, if it is not available then money and effort has been wasted. *What are CHELATED MINERALS ? When minerals such as zinc, manganese, magnesium, copper, iron, calcium, and others become surrounded by and bonded to amino acids, in a stable form, this is referred to as CHELATION. Chelation is a natural means for the body to transport minerals across the intestinal wall as part of digestion. *Why are minerals bound to amino acids to form a chelate ? The body is very efficient at absorbing amino acids. In a priority list of nutritional substance crossing the intestinal wall, after digestion, Dipeptides (two amino acids linked together through a special bond) and single amino acids rank highly. In fact dipeptides now appear to absorbed at a Higher rate than a single amino acid. This an apparent by- product of their special active transport mechanism of absorption. It has been seen that dipeptides are removed from the interior of the intestine at a much faster rate than single amino acids. Chelating minerals to amino acids, in a dipeptides-like fashion, allows this mineral form to be smuggled via this special active transport system across the intestinal lining and into the system. |
