|Image 1: The magic ingredient is in the root not in the commonly eaten leaves of "bok choy". Chances that you will find a "whole" (including the root) chinese cabbage" (lat. brassica rapa) at your local supermarket, are yet very low... but wouldn't this be a good reason to start gardening really "whole" foods in your backyard?

As Trisha Gura points out in a newsitem on sciencemag.com,
[t]he current trio of [weight loss] drugs on the market, endocrinologists say, is, at best, weak and, at worst, plagued by side effects. Hoffmann-La Roche's Xenical, for instance, blocks fat-digesting enzymes called lipases. That prevents the gut from digesting and absorbing fat. But lipids aren't the only molecules malabsorbed; Xenical also causes cramping and severe diarrhea in many obese patients because water molecules also fail to be taken up by the gut.Thus, the study results of Sojin An and his colleagues from five different research centers in the Republic of Korea, which although they have been published back in 2009, landed in my inbox only recently, come along quite handy. In a 8-week controlled trial the scientists found that the addition of 50mg/kg of an ethanolic extract from Brassica campestris spp. rapa roots (human equivalent: 4mg/kg) to the high fat diet (+25% more calories than standard chow) of ICR (imprinting control region) mice did not only ameliorate the weight and fat gain, but even reduced both gains in body weight (-3%), as well as white adipose tissue weight (-8%) compared to the normal fed control group.

In case you are as annoyed as I would be by the branding in the figures, I suggest you tell my friend "The Press" over at Anabolic Minds that "copy + pasting" the work of others like that, instead of citing only parts of the article and linking back to the source, is not what one would expect of an "anabolic mind". Thanks!

- fatty acids from the pollen of brassica campestris have been shown to have a "strong inhibitory" effect on aromatase (Yang. 2009),
- the leaves protect "against in vivo genotoxicity and oxidative stress" (Tiku. 2008), and
- the chloroform extract from its pollen kills prostate cancer cells (Wu. 2007),
