Today we learn about "elemental good health." Why is it that eating bright colored stuff is better then packaged stuff.

This is more of a shoot from the hip.

This is an artsy-draw day. You can choose not to participate, but then you need flash cards to memorize 10 of them. . Once this is done, then by groups, we will put them on the board. The best ones throughout the classes will be posted. One of each, as a reminder of what/why is important.

Was this taken from wiki, yes. Is it right, yes

Macrominerals Many elements are essential in relative quantity; they are usually called "bulk minerals". Some are structural, but many play a role as [|electrolytes].[|[][|19][|]] Elements with recommended dietary allowance ([|RDA]) greater than 200 mg/day are, in alphabetical order (with informal or folk-medicine perspectives in parentheses):
 * [|Calcium], a common electrolyte, but also needed structurally (for muscle and digestive system health, bone strength, some forms neutralize acidity, may help clear toxins, provides signaling ions for nerve and membrane functions) [//[|citation needed]//]
 * [|Chlorine] as [|chloride] ions; very common electrolyte; see sodium, below
 * [|Magnesium], required for processing [|ATP] and related reactions (builds bone, causes strong peristalsis, increases flexibility, increases alkalinity) [//[|citation needed]//]
 * [|Phosphorus], required component of bones; essential for energy processing[|[][|20][|]]
 * [|Potassium], a very common electrolyte (heart and nerve health) [//[|citation needed]//]
 * [|Sodium], a very common electrolyte; not generally found in dietary supplements, despite being needed in large quantities, because the ion is very common in food: typically as [|sodium chloride], or common salt. Excessive sodium consumption can deplete [|calcium] [//[|citation needed]//] and [|magnesium], [//[|verification needed]//] leading to high blood pressure and osteoporosis.
 * [|Sulfur], for three essential amino acids and therefore many proteins (skin, hair, nails, liver, and pancreas). Sulfur is not consumed alone, but in the form of sulfur-containing amino acids

[[|edit]] Trace minerals
Many elements are required in trace amounts, usually because they play a [|catalytic] role in [|enzymes].[|[][|21][|]] Some trace mineral elements (RDA < 200 mg/day) are, in alphabetical order:
 * [|Cobalt] required for biosynthesis of [|vitamin B12] family of [|coenzymes]. Animals cannot biosynthesize B12, and must obtain this cobalt-containing vitamin in the diet [//[|citation needed]//]
 * [|Copper] required component of many redox enzymes, including [|cytochrome c oxidase] [//[|citation needed]//]
 * [|Chromium] required for sugar metabolism [//[|citation needed]//]
 * [|Iodine] required not only for the biosynthesis of [|thyroxine], but probably, for other important organs as breast, stomach, salivary glands, thymus etc. (see Extrathyroidal [|iodine]); [//[|citation needed]//] for this reason iodine is needed in larger quantities than others in this list, and sometimes classified with the macrominerals
 * [|Iron] required for many enzymes, and for [|hemoglobin] and some other proteins [//[|citation needed]//]
 * [|Manganese] (processing of oxygen) [//[|citation needed]//]
 * [|Molybdenum] required for [|xanthine oxidase] and related oxidases [//[|citation needed]//]
 * [|Nickel] present in [|urease] [//[|citation needed]//]
 * [|Selenium] required for [|peroxidase] (antioxidant proteins) [//[|citation needed]//]
 * [|Vanadium] (Speculative: there is no established RDA for vanadium. No specific biochemical function has been identified for it in humans, although vanadium is required for some lower organisms. [//[|citation needed]//] )
 * [|Zinc] required for several enzymes such as [|carboxypeptidase], [|liver alcohol dehydrogenase], and [|carbonic anhydrase] [//[|citation needed]//]
