Doggedly following advice to drink at least eight glasses of water a day is said to be of no health benefit to most people and only enriches bottling companies.
And it makes people go to the toilet a lot.
Public health researcher Rob Quigley said yesterday adults typically needed around 2 litres of fluids a day, but did not need to obtain all of this by drinking water.
“We get a lot of fluid from food. Fruit and vegetables are upwards of 90-95 per cent water. Eating an apple a day is a little bit like drinking a glass of water.”
Australian university lecturer Spero Tsindos, who examines water consumption in the latest edition of the Australian and New Zealand Journal of Public Health, said encouraging people to drink large amounts of water was driven by vested interests.
Pricier brands of bottled water can cost more than $3 a litre at New Zealand supermarkets.
A Pennsylvania University research review published in 2008 found no evidence that drinking eight glasses of water a day improved skin tone, aided dieting or prevented headaches (except those induced by hangovers).
A person’s daily fluid needs, in addition to the quantities derived from food and plain water, can be supplied from tea, coffee and even moderate amounts of mildly alcoholic drinks such as beer – despite their mildly diuretic effects – and various other drinks.
“Out of all the fluids to drink,” Mr Quigley said, “water is one of the best, Read more…
Corrosion discovered at one of the City of Madisonville’s water wells sparked a discussion about fluoride levels in the City’s drinking water at a recent City Council meeting.
City Council at its regular meeting May 14 discussed the possibility of ceasing to add the chemical to the City’s supply altogether or reducing the amount injected into the system.
Currently, the City injects enough fluoride into its drinking water to bring the level to between 0.7 and 0.8 parts per million, a level recommended by the U.S. Department of Health and Human Services. Council members and city staff questioned the impact that injecting fluoride into the City’s water system has and will continue to research the issue and prepare a recommendation for a later meeting.
“If we’re going to continue to lower (fluoride levels in the water), it might just be best to take it out of the system altogether,” Public Works Director Kevin Story said.
City staff discovered corrosion at Water Well No. 5 approximately one month ago and upon contacting an engineer received the recommendation that they reduce the level of fluoride being injected into the water supply. Read more…
Any experienced runner can educate you on why it is important to stay properly hydrated before you run, while you run and after you have finished a run. A healthy fluid intake helps runners to avoid suffering dehydration and heat exhaustion. It also limits the chance of developing muscle cramps or other similar injuries and promotes optimal performance.
There is much more involved in staying hydrated while running than simply drinking lots of water. Proper hydration begins before you lace up your running shoes and continues after you kick them off. Failing to maintain fluid levels is foolish and dangerous.
Consider these 10 hydration tips to enhance your runs:
Calculate sweat rate: Everyone has different fluid needs. Calculate your sweat rate to determine how much fluid you need during a run. Read more…
