Pilots need to keep hydrated. Water helps the body to..
  • A
    absorb nutrients.
  • B
    retain its waste materials for long periods during flight.
  • C
    regulate the amount of sugar in the blood.
  • D
    reduce the risk of hypothermia.

Adequate consumption of water is important for digestion and nutrient absorption in several ways. Water itself is a relatively minor source of most nutrients and vitamins. There are some minerals in drinking water, though, such as calcium and magnesium. Most minerals and many vitamins are soluble in water; solubility is what makes them accessible to cells and the transporters that bring them into the body.

Water is used as well as generated in metabolic chains and circles. It is also contained in the blood plasma, allowing the transport of nutrients, oxygen and waste products throughout the body.
