Water and Minerals in Human Nutrition

Questions and Answers

What is the consequence of severe dehydration, as evidenced by the college wrestler's tragic incident?

Severe dehydration is a life-threatening condition that requires urgent medical care.

What is the primary reason why the college wrestler's body lost a significant amount of 'water weight' during his intense training session?

Sweating caused the body to lose a significant amount of 'water weight'.

What is the difference between losing 'water weight' and dehydration?

Losing 'water weight' refers to the loss of water from the body, whereas dehydration refers to body water depletion that can lead to severe health consequences.

Study Notes

Dehydration

Dehydration can occur when water intake is restricted, leading to body water depletion, which can be life-threatening if not treated promptly.
Severe dehydration can cause hyperthermia, fatigue, and ultimately, death.

Water Importance

Water is essential for human survival, and we can survive for weeks or months without other nutrients, but not without water.
Water makes up a significant portion of body weight, and its functions involve certain minerals.

Mineral Classification

Essential minerals are classified into two groups: major minerals and trace minerals.
Major minerals are required in amounts of 100 mg or more per day, while trace minerals are required in smaller amounts.
Possible essential minerals are those whose essential nature has not been fully determined.

Mineral Examples

Major minerals: calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur.
Trace minerals: chromium, copper, fluoride, iron, iodine, manganese, molybdenum, selenium, and zinc.
Possible essential minerals: arsenic, boron, lithium, nickel, silicon, and vanadium.

Mineral Functions

Mineral nutrients are key components of body structures and play vital roles in metabolism, water balance, muscle movement, and other physiological processes.
Mineral deficiencies can cause serious health problems, including death.
