Normal daily intake of potassium is 70-100 mEq (270 to 390 mg/dl), and requires the kidneys to remove that same amount each day. If more is removed, the body's total potassium store will be decreased, and the result is hypokalemia (hypo=low + kal=potassium +emia= in the blood) occurs. Potassium enters the body through dietary intake. Examples of potassium rich foods include:
Mandan, self-name Numakiki, North American Plains Indians who traditionally lived in semipermanent villages along the Missouri River in what is now North Dakota. They spoke a Siouan language, and their oral traditions suggest that they once lived in eastern North America.
The second village was Rooptahee (Ruptdre, Nuptadi), in McLean County, North Dakota. It has been destroyed by river changes and no trace of it can be found today. It is called the Black Cat site, after the village chief during the Lewis and Clark period. The Mandans were an agricultural people who lived - and continue to live - on the Missouri River. Cultural traits and ancient village sites suggest an origin far to the southeast in the Mississippi Valley, but they have been on the Missouri longer than Europeans have been in North America.
