[12:12.60]Water
[12:14.34]Water is a vital component of our diets,
[12:18.57]even though it's not considered a specific nutrient.
[12:22.88]Water makes up 50 to 70 percent of an adult's total body weight.
[12:29.79]Without regular top-ups, our body's survival time is limited to a matter of days.
[12:36.32]Water is essential for the body's growth and maintenance.
[12:41.42]For example, it helps get rid of waste and regulates temperature,
[12:46.46]and it provides a medium for biological reactions to occur in the body.
[12:52.00]Water is lost from the body through urine and sweat,
[12:57.72]and must be replaced through the diet.
[13:00.65]If you don't consume enough water, your kidneys suffer,
[13:04.57]causing symptoms such as headaches, tiredness and loss of concentration.
[13:10.54]Most healthy adults need between 0.5-3 litres a day,
[13:17.76]so aim to drink 6-8 medium glasses of fluid daily.
[13:23.54]Beverages such as tea, coffee and fruit juices count towards fluid intake,
[13:30.14]and may bring with them other nutrients or benefits.
