Iron is an essential mineral used to transport oxygen to all parts of the body.
The body is able to regulate uptake of iron, so overdose is rare and usually only occurs when people take supplements.
While iron is better absorbed from heme (meat) sources, non-heme (plant) iron is better regulated causing less damage to the body.
Minerals are inorganic elements that originate from rocks, soil, or water. However, you can absorb them indirectly from the environment or an animal that has eaten a particular plant. Minerals can be divided up into three different categories:
Trace minerals (aka microminerals)
The more calcium you consume, the less you absorb. Though consuming more calcium will increase your total level.
Children absorb about 60% of the calcium from foods, while adults absorb only 20%. Calcium absorption decreases with age and people over 50 should eat more calcium.
Unless you are on dialysis or have a special condition, an overdose of potassium from natural sources is nearly impossible.
Boiling vegetables in water and discarding the water they are cooked in can help reduce their potassium and electrolyte content.
Iodine is a component of almost every living plant and animal. In general, foods from the sea contain the most iodine, followed by animal foods, then plant foods. Of all foods, seaweed (like kelp), is the most well known and reliable source of natural iodine.
In your entire lifetime you will need less than a teaspoon of iodine to ensure good health, however, since it is dangerous to consume that much iodine at once, it is best to eat a little each day.
The time a mineral is ingested into the body, to the time it is excreted, it is never changed into anything else. Minerals are split into two groups: major and trace. Major ones are not necessarily more important than trace, but it means there are greater amounts in your body.
They amount to less than a teaspoon of a person’s body weight. The nine trace minerals are: Iron, Manganese, Zinc, Chromium, Copper, Molybdenum, Iodine, Flourine and Selenium.
The seven major minerals are: Calcium, Sodium, Phosphorus, Chloride, Potassium, Magnesium and Sulfur.
Sodium and Chloride
Since sodium is required by all life to exist, it is naturally found in all foods and does not need to be added. 6 grams of salt a day is the limit anyone should eat, and we get most of these 6 grams from just eating normal food without putting any salt on it at all.
Selenium can be divided into two categories: Organic and Inorganic. The primary inorganic forms of selenium are selenite (SeO3) and selenate (SeO4). The most common organic form of selenium is selenomethionine.
Phosphorus is found in almost every food, and as such, deficiency is rare
