Soft Drink - Hard Facts! - by Dr Dingle

 

Soft drinks are a noxious cocktail of substances that play havoc with your body. They‘re highly acidic, contain artificial colours and flavourings and high levels of sugar or artificial sweeteners. Over the next 10 years you are going to read a lot more literature on the toxic effects these drinks have on our kids. Most (if not all) soft drinks have huge amounts of sugar (such as 10 or more teaspoons per can) that creates a sugar rush into the blood, in the same way as other high GI foods. The sugar is quickly converted to body fat. If it stays in the blood, it causes some free radical damage. The general guidelines for sugar consumption for a 70-kilogram teenager are no more than 10 – 12 teaspoons of sugar a day. One average can of soft drink will exceed that amount. For younger and smaller children the amount of sugar should be substantially less.

Now the medical solution to this problem is to come up with a drug (which has adverse side effects) to reduce the calcium loss from the bone. My solution is to eat more vegetables and to reduce the intake of soft drinks. (For more information on soft drinks, keep an eye out for my next book, “Soft Drinks - Hard Facts”).

• Drink less soft drinks;
* Drink more water;
* A little tea is okay, but remember a strong cup of tea can contain as much caffeine as a cup of coffee. Tea is full of antioxidants, even tea with milk, but don’t make it too strong.
• Coffee is full of stimulants that trigger of the production of dopamine then adrenaline and noradrenaline. That is, it triggers a mini stress response. A little coffee is fine, but remember, it’s a stimulant and takes about six hours for half of it to be excreted from your body, so don’t have it late in the day.

Tea

A study published in February, 2004 showed that when heavy smokers drank four cups of green tea per day for four months there was a significant decrease in a urinary marker of DNA damage (Hakim 2004). Green tea might also be beneficial for those undergoing conventional treatment for cancer, although that is far from proven.
