New Zealand’s largest source of bottled water is the Blue Spring in Putaruru, Waikato.
There have been no recalls or reports of unsafe bottled water in New Zealand.
In a blind taste test on the show, comparing bottled and tap water, 75 % of people preferred the taste of tap water over bottled water.
Worldwide, approximately 1500 plastic bottles end up in landfills and oceans every second
There is no scientific study that has led to the “8 glasses of water” a day recommendation. The Ministry of Health recommends a daily fluid intake of 3.4 litres for men and 2.8 litres for women. However, fluid doesn’t only come from water, other drinks and food provide some too. A fifth of our fluid comes from food!
Sparkling water is simply carbon dioxide dissolved in water. Carbon dioxide also lowers the pH of water meaning it is more acidic.
One of the biggest growth areas in the drinks aisle over the last ten years has been energy drinks. Their main active ingredient is caffeine.
Caffeine binds and interacts with receptors in the brain which changes the speed at which signals are processed and sent around the central nervous system.
Caffeine also improves the rate at which our brain can process information, make decisions and react to different stimuli.
The amount of caffeine in most energy drinks is around about 30 milligrams per 100 millilitres of liquid. This is roughly about the same amount of caffeine that you would get in a coffee.
Energy drinks must include an advisory statement that the product is not recommended for children, pregnant or breastfeeding woman or individuals sensitive to caffeine but sales are not regulated.
Six hours after consumption there may be as much as half the amount of caffeine still in your system.
Some experts believe that high levels of caffeine could hinder brain development. As well as this, there is a tendency for impulsiveness, explosive behaviour, and a strong predisposition for reckless behaviour.
Under Food Standards Regulations the maximum amount of caffeine a “formulated caffeinated beverage” can contain is 320mg per litre. However, energy shots come under a different standard that doesn’t limit caffeine.
The policy concerning the use of caffeine in drinks is currently being reviewed by the Ministry for Primary Industries.
When you add caffeine in the right quantities to a regular sport drink you can improve athletic performance.
Caffeine acts as a diuretic when we’re resting which is why we urinate more frequently when we’re drinking coffee. However when we start exercising, signals are released to help us retain and conserve water that we are losing during exercise.
Sugary beverages are the second greatest source of sugar for adults.
For our children, drinks are their greatest source of sugar – more than fruit and sweets.
More than 90 grams a day of sugar is regarded as a high intake for adults. On average, New Zealand children are consuming a whopping 124 grams of sugar per day.
