seeing as what the title of this thread is I thought id throw some abstracts about. Now if you anything like me, your thinking, right now, what are the Effects of dietary intake of soy protein and isoflavones on cardiovascular disease risk factors in high risk, middle-aged men in Scotland?! and the answer, courtesy of Sagara et al ( http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=14963058 ) is that Dietary intakes of soy protein (at least 20 g) and isoflavones (at least 80 mg) for 5 weeks would be effective in reducing CHD risk…
…hmmmmmmmm so soy is good then?
well, again, if your at all like me your now thinking… “Monkeys! make him say something about monkeys! theyr so funny with their banana eating antics, teeheehee! i wonder what would happen if we rammed yummy soy down their throats… would it lower their CHD risk?!”
Well, I dont know about their CHD risk, but Simon et al noticed Increased aggressive behavior and decreased affiliative behavior in adult male monkeys after long-term consumption of diets rich in soy protein and isoflavones! ( http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15053944 ) good god! damn evil soy makes us anti social and heres an extract:
“the proportion of time spent by these monkeys in physical contact with other monkeys was reduced by 68%, time spent in proximity to other monkeys was reduced 50%, and time spent alone was increased 30% (P’s < 0.02). There were no effects of treatment on serum testosterone or estradiol concentrations or the response of plasma testosterone to exogenous gonadotropin-releasing hormone (GnRH).”
Finally, on a more serious note (moving away from the funny cute monkeys…) answering a serious personal concern of mine is Giampietro et al ( http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15055353 ) with a sample of 48 children (yaaawn) with a range of 7-96 months. hmm. small sample, big range, qudos to these lads for the much needed research but im not hanging any assurances of this one. although god only knows PETA will be! entitled Soy protein formulas in children: no hormonal effects in long-term feeding, the study says that
“none of the enrolled girls showed signs/symptoms of precocious puberty and none of the boys presented gynecomastia; bone age was within the normal range.”
soooo there you have it. soy good for rats, bad for monkeys, great if your an atherosclerotic Scot, and pretty damn boring if your an Italian child.
