|Skip the fireworks invest the money in some quality ingredients for a fondue or whatever you like and invest the (often non-negligible) rest of the money in a gym membership for the next year.|
I mean, it could be that they spent so much money on their fireworks that they feel they can only afford the junkfood of which everybody and his/her mama still tend to believe that it would be cheaper than buying fresh products and preparing your own food from those.
Ah, I am ranting. That's usually Carl Lanore's task, so I will better go on with the items I have compiled for the today's last installment of On Short Notice in the year 2012:
- Berberine + yohimbine - a synergistic duo to prevent LPS toxicity (Li. 2012) -- With all the recent hoopla about the gut microbiome, I suppose that I don't have to tell you what the acronym LPS stands for, right? Hmm... just to make sure it stands for lipopolysaccharide endotoxins which are produced by gram negative bacteria in your gut and are so "toxic" (in fact they cause profound inflammation) that they can be lethal at higher doses.

The mechanism is mediated by the prevention of liver injury, an upregulating of IL-10 production (an anti-inflammatory cytokine), and related anti-inflammatory effects resulting from the suppression of phosphorylation of IkBa, JNK, ERK and IRF3 in macrophages.
- Chronic 9-week high BCAA diet impairs brain tryptophan levels and causes anxiety (Coppola. 2012) -- Scientists from the Duke University took another look at the BCAA-tryptophan depression connection, you may have read about in the context of my "Sugar Addicted or Just Stressed Out?" post from January 3, 2012.
According to the results Anna Coppola and her colleagues are about to publish in the American Journal of Physiology - Endocrinololgy and Metabolism the provision of a BCAA-enriched diet for 9 weeks leads to both reductions in brain tryptophan levels and an increased turnover of serotonin (5-HT) in rodent brains:
"Recent studies demonstrating a strong association between BCAA levels, obesity, and obesity-related metabolic disorders, when linked to the findings reported here, may help to explain the strong association between obesity and behavioral abnormalities, including depression and anxiety." (Coppola. 2012)
As the slight differences between the high an low carb diets show, other nutrients can influence serotonin as well (read more)
Bottom line: Isolation is not what you want if what your body has been build for is complex food. And while the single serving of BCAAs you may gulp down during or right before a workout, on the other hand, probably isn't going to harm you. The "I need BCAAs every 30min" approach to gaining muscle mass, may well turn you into a psychotic wrack if you follow it day in and day out for months or years - at least without chronically adding some l-tryptophan to the equation.
- Sweet tea leaves protect against obesity: Once more via PPAR-gamma blockade (Zhou. 2012) -- Actually this is probably not news to anyone out there with a degree in Traditional Chinese medicine. After all, Lithocarpus polystachyus Rehd.(Sweet Tea) is Chinese folkloric medicine that has always been used to treat obesity, diabetes, and hypertension in South China:
"Previous experiments revealed that it contains plentiful bioactive flavonoids and polyphenolic compounds, e.g. phlorizin, trilobatin, 3-hydroxy-phlorizin, etc. These components have extensive pharmacological activities, such as anti-diabetes, memory improvement, anti-aging, inhibition of lipid peroxidation and the growth of human colon cancer cells, and so on." (Zhang. 2012)From a "scientific" perspective, however, the efficacy of this herbal medicine as an obesity treatment had still to be elucidated.
Figure 4: Effects of oral gavage of 75 mg, 150 mg and 300 mg/kg of body weight/day of sweet tea extract or placebo (DIO) in conjunction with the 8 weeks on a obesogenic diet (Zhang. 2012)
In other words, this is research in progress, but I suppose something you are going to hear more about at the Supppversity in 2013.
