Stop Oxidants? Stop Breathing! The Antioxidant Hoax

Evidence gathered over the past few years shows that, at best, antioxidant supplements do little or nothing to benefit our health. dark red quote 2

Eat. Pray. Breathe Oxidants.

We breathe oxygen. The oxygen is carried around our body by red blood cells. And, guess what? Oxygen is an oxidant. It ‘burns’ or ‘oxidises’ fuel in our cells. We get energy. The red blood cells then carry the carbon dioxide produced by oxidation back to our lungs and we breathe it out. Sometimes, these oxidising reactions are incomplete producing free radicals or, as scientists like to call them, Reactive Oxygen Species, ROS.

Lisa Melton attacked the popular belief that anti-oxidants have magical health benefits in the New Scientist. In the article biochemist, Barry Halliwell from the National University of Singapore explains that “One percent of the oxygen we consume turns into ROS.” Other free radical producing factors include X-rays, smoking, air pollutants, bacteria, and intensive exercise. When subjects with diets high in fruit and veg were found to suffer a lower incidence of heart disease, diabetes, dementia, stroke and some cancers the theory that antioxidants mop up free radicals was born. It has sponsored a $US 23 Billion supplement industry and that is not even including superfoods.

According to Melton ‘Time and again, however, the supplements failed to pass the test. ‘True, they knock the wind out of free radicals in a test tube. But once inside the human body, they seem strangely powerless.’ Evidence suggests that sometimes anti-oxidants can even do harm. One study involving 18,000 subjects had to be stopped when researchers found the cancer rates rose in those given beta carotene supplements.

Even antioxidants should be consumed in moderation.

Drinking 8 glasses of water a day for Dummies

Even as I write these lines some self-proclaimed health adviser will be insisting that for optimum health you should drink 8 glasses of water a day.

This assumes two things:

1. You are incapable of deciding if you are or are not thirsty. Answer this question. What day is it? Correct. As you do not appear to have dementia, you will remember to drink fluids.

2. That 8 glasses is the correct fluid intake for you. How do they know?

Meanwhile, the claim that you need eight 8-ounce glasses of water a day has been debunked.

Drs. Dan Negoianu and Stanley Goldfarb at the University of Pennsylvania reviewed published clinical studies on the topic and found no data to suggest people need to stick to the “8 x 8″ rule.

“Indeed, it is unclear where this recommendation came from,” they write in an editorial in the June 2008 issue of the Journal of the American Society of Nephrology.

Why we eat ourselves crazy

Sibylesque Mad Professor labOnce all scientific research was filtered through the peer review process. Initial studies were tested by others and if the results could be replicated, they were eventually published in mainstream papers.

These days, to get funding, researchers release their results directly to newspapers. Later studies may show that the initial research was flawed but the damage is already done.

Here are 6 ways the healthy food message messes with our minds:

1.Oops! Crazy Professor (Superfood Claim Superbollocks)

2. Too many statisticians spoil the broth (Eat Meat and Die. Oops! Got the maths wrong.)

3. Seemed like a good idea at the time (Stop Oxidants? Stop Breathing! The Antioxidant Hoax)

4. Just made that one up (Drinking 8 glasses of water a day for Dummies),

5. Getting carried away with numbers again ( Winning the Salt Wars or Never Trust a statistician)

6. How marketing controls your mind (Would you eat a button? Millions do!)
