Welcome!


Thanks for visiting! My goal here is to discuss the latest scientific research to separate the good from all that "guff" in nutritional sciences and all aspects of human health. Because the more you Know, well...the more you Know!

A Bunch of Older (but Still Recent) Research

This post will be a bit of a mish-mash of various studies I've covered in the past via Twitter. However, since most of you reading this nutrition research blog are not on Twitter, I thought I'd do this one-time post to bring you up to speed on some of my favourite studies in the past 5 or 6 months. Here we go...

In October 2010, Osteoporosis Canada took a step in the right direction...they will now start to focus less on BMD (bone mineral density) and more on fracture risk. This is something I've been saying for a while now, and why I believe the best "bone health" supplements will also target collagen formulation. What's needed for healthy collagen? Proline, lysine, vitamin C, zinc, copper, silicon, etc. If you have no idea what I'm talking about... increasing BMD (which isn't that difficult to do), in clinical trials, hasn't resulted in a reduction in fractures. The thinking is that people end up with dense, but brittle bones. That's why healthy collagen is essential to bone health...it allows bones to have a slight degree of flexibility.

This study on pilots found that niacin (a form of vitamin B3) prevented DNA damage during flights. Cosmic radiation, jet fumes, etc... now I'm justified when people give me odd looks for downing a handful of supplements before flying.

It should be common sense by now that environmental health is directly related to human health as shown in this study/article as well as this one (I would recommend you eat organic to have an even greater impact). Now, an FSA report warns climate change could provoke unhealthy food choices (by making healthy foods more expensive).

And if your health wasn't reason enough to become a tree-hugger, this study showed traffic-related air pollution causes signs of skin aging (increased pigmentation & wrinkles).

As a coffee lover, this study was reassuring... the "EPIC study" showed coffee and tea reduce the risk of brain tumors. Let's go for coffee. Any takers?

Another reason to indulge...polyphenol-rich chocolate may reduce symptoms of chronic fatigue syndrome. Let's go for coffee...AND chocolate. That would be heaven.

In a study on probiotics, it was shown to have psychotropic effects...they not only relieved depression, but reduced anger, anxiety, and improved problem solving. Here's another one showing probiotics' effect on lowering cholesterol.

This study on CoQ10 showed it benefited those with hearing loss.

Vitamin D3 (at 4000 IU per day) improved blood sugar control in Type 1 Diabetics. Click this link to take you to the full-text publication.

Lastly, alpha-lipoic acid (ALA) improved endothelial-mediated arterial dilation in those with impaired fasting glucose. This is a tricky supplement though since most don't realise alpha-lipoic acid is temperature sensitive and should be stored in the fridge. My suggestions, look for R(+) alpha-lipoic acid (this is the form humans use) that's been stabilized (so doesn't need to be kept in the fridge).

Wow, you made it to the end of this post! Don't you feel smarter now?
