Nutrigenomics: The new way forward for your nutritional needs?

February 21st, 2008

Nutrigenomics

It sometimes confusing when one is bombarded with disparate views on various health topics. For example, one minute we are told that coffee is good for us, the next we are told that it is bad. What the…!? Okay, confusing is not the right word…maybe frustrating? Annoying? Sort it out Mr. Scientist? You get my point.

I’m about to present to you a fascinating way to discover the benefits of foods catered specifically for you (soon), yes you the individual! Well, it’s nothing really to do with me. I came across an interview conducted by Dr. John Berardi where he interviewed Dr. El-Sohemy in regards to ‘Nutrigenomics’. I found it so interesting I had to publish the article here.

Here’s an extract from the email I received from Dr.Berardi:


For example, what if I were to tell you that:

- Coffee reduces your risk of heart disease by 3x,
if you have one very specific gene

- However, if you have the opposite gene, your risk
goes up 10x

Also, what if I were to tell you that:

- Fish oil lowers blood lipids (like triglycerides),
if you have one very specific gene

- However, if you have the opposite gene, you don’t
get the same benefits

In addition, what if I were to tell you that:

- 3-5 cups of green tea per day is highly
beneficial, if you have one very specific gene

- However, if you have the opposite gene, you’ll
only need 1-2 cups for the same benefits

Well, I’m going to be telling you all of these things - and
more - in the following interview, an interview that
promises to change the way you view nutrition.

So without further to do, here’s the link:

P.S. I highly recommend Dr. Berardi’s ‘Precision Nutrition’ programme for weight loss/gain and healthier eating recipes.

Deodorants, Coffee And Artificial Sweeteners Not Linked To Cancer?

February 8th, 2008

Deodorant

A new risk assessment tool suggests that deodorants, coffee and artificial sweeteners may not be linked to cancer. The tool has been developed through the Cancer Control Program at South Eastern Sydney & Illawarra Health (SESIH) by UNSW researcher, Professor Bernard Stewart.

“Our tool will help establish if the level of risk is high – say, on a par with smoking – or unlikely such as using deodorants, artificial sweeteners and drinking coffee or fluoridated water – or at risk bands in between,” said Professor Stewart.

“The media are filled with reports about possible causes of cancer: most commonly, a new and unexpected exposure to a previously suspected carcinogen.”

“It’s one thing to know that arsenic is carcinogenic - but quite another to distinguish between different methods of exposure. That’s what this approach achieves,” said Professor Stewart. “For instance, smelter workers who are exposed to arsenic emissions are much more likely to develop cancer than children who have played on climbing frames constructed from arsenic-treated timber – but the carcinogen is the same.”

Until now there have only been mathematical risk assessments, which are complicated and of a limited application.

“Our approach can be used whenever carcinogenic risk can be implied,” said Professor Stewart.

In an issue of the journal Mutation Research Reviews, the newly developed procedure has been applied to more than than 60 situations, ranging from active smoking to electromagnetic fields in the workplace – which are all deemed to offer some degree of carcinogenic risk. Consequently, each situation can be located within one of five bands corresponding to proven, likely, inferred, unknown or unlikely risk of carcinogenic outcome.

Surveys suggest that tobacco smoking is correctly identified as the major cause of cancer, but a host of other situations – using a mobile phone, air pollution, exposure to DDT, eating dioxin-contaminated fish, using hair dyes, and drinking alcoholic beverages – are often given similar risk status.

“We now have a means of indicating which carcinogenic risks are comparable by reference to the type of evidence available,” says Professor Stewart. “This risk assessment gives the lie to the attitude that ‘everything causes cancer’.”
