Water and Hydration

Hydration

This refers to the process of maintaining or restoring the body’s water balance

Intracellular Fluid (ICF)

• water inside the cells

• most of the body’s water is here because cells need water for metabolism, chemical reactions, and nutrient transport

Extracellular Fluid (ECF)

• water outside the cells

• this protective role reduces friction and prevents damage to tissues during movement

Synovial fluid

Joints contain _____ _____ which is mostly water

• this fluid reduces friction between bones, allowing smooth & pain-free movement

Free Water

• this is the most abundant form in most foods

• this is the primary water content that contributes to hydration upon consumption and provides the sensation of “juiciness”

Bound Water

• tightly held moisture

  • this water is chemically or physically attached to food components like proteins, carbohydrates, and minerals via hydrogen bonding

Imbibed Water

• absorbed moisture

• an intermediate state, this water is physically trapped or absorbed by hydrophilic (water-loving) substances

• this water is released during digestion and contributes to hydration

metabolic water

a small amount of water is generated as a by-product of energy metabolism (oxidation of macronutrients)
