Review for test #3
1. Calcium is not well absorbedless that 30% 2. A major mineral means you need more of it. 3. The six major minerals are calcium, phosphorus, magnesium, sodium, potassium, and chlorine. The rest are trace minerals, which are not less important, but you just need them in less amounts. 4. Minerals are 0 calories. 5. The best source of iron is beef, liver, or meat. 6. The best source of zinc is beef, liver, or meat. 7. Vitamin C will help you absorb iron twice as much (double the absorption). 8. Sea salt, they say, contains iodide, but it is silly to pay more and get nothing extra for it. Sea salt is not better than table saltiodine leaves as a gas (sublimes from solid to gas form). 9. We need iodide to make thyroid hormone, which is important because it influences our overall metabolism. Also, if you don’t have enough iron, you will be fatigued, and children that are deficient won’t grow. Finally, you need it to prevent goiter, an enlargement of the thyroid (around the Great Lakes and west = the goiter belts). 10. The major function of zinc: for many enzymes systems to work, for sexual maturation and growth, for wound healing, for protein metabolism and immune system. 11. Fluoride deficiency will result in dental caries (holes in teeth). 12. There is 500 mg of calcium carbonate in Tums, but since calcium carbonate is only composed of 40% calcium, there is 200 mg of pure calcium in Tums. 13. Iron is VERY POORLY absorbed; only 5-10% of iron is absorbed by normal adults. 14. The best source of potassium is potatoes. 15. If you don’t have enough potassium, it may result in cardiac arrest or an irregular heartbeat (death) [also caused by too much]. 16. The major function of magnesium that it is needed as part of bones and part of muscle; also, it is an activator of more than 300 enzymes, and it’s necessary to maintain electrical potential of nerve and muscle and for transmission of
