Estrogenic Plants Linked to Altered Hormones, Possible Behavior Changes in Monkeys

ScienceDaily (Nov. 19, 2012) Eating certain veggies not only supplies key nutrients, it may also influence hormone levels and behaviors such as aggression and sexual activity, says a new study led by researchers at the University of California, Berkeley, that could shed light on the role of diet in human evolution. The research is the first to observe the connection between plant-based estrogenic compounds, or phytoestrogens, and behavior in wild primates -- in this case, a group of red colobus monkeys in Uganda.
 
The more the male red colobus monkeys dined on the leaves of Millettia dura, a tropical tree containing estrogen-like compounds, the higher their levels of estradiol and cortisol. They also found that with the altered hormone levels came more acts of aggression and sex, and less time spent grooming -- an important behavior for social bonding in primates.
 
The study, published in the current issue of the journal Hormones and Behavior, suggests how potentially important consuming phytoestrogens is in primate ecology and evolution.
 
"It's one of the first studies done in a natural setting providing evidence that plant chemicals can directly affect a wild primate's physiology and behavior by acting on the endocrine system," said study lead author Michael Wasserman, who conducted the research as a graduate student at UC Berkeley's Department of Environmental Science, Policy and Management. "By altering hormone levels and social behaviors important to reproduction and health, plants may have played a large role in the evolution of primate -- including human -- biology in ways that have been underappreciated."
 
For 11 months, the researchers followed a group of red colobus monkeys in Uganda's Kibale National Park and recorded what the primates ate. For behavioral observations, the researchers focused on aggression, as marked by the number of chases and fights, the frequency of mating and time spent grooming.
 
To assess changes in hormone levels, the researchers collected fecal samples once a week from each of 10 adult males in the group (a separate study examining phytoestrogens in females is ongoing). More than 407 samples were collected and analyzed for estradiol and cortisol levels.
 
The researchers found seasonal variation in the consumption of estrogenic plants, which made up 0.7 percent to as much as 32.4 percent of the red colobus diet in any given week. For red colobus adult males, higher consumption of estrogenic plants corresponded to higher levels of estradiol and cortisol, two steroid hormones important to reproduction and the stress response.
 
Phytoestrogens are also found in human foods, especially soy and soy-based products. Millettia dura, the tropical tree that was most important to red colobus monkey hormone levels and social behaviors, is a close relative of soy.
 
"With all of the concern today about phytoestrogen intake by humans through soy products, it is very useful to find out more about the exposure to such compounds in living primates and, by analogy, human ancestors," said study co-author Katharine Milton, professor in UC Berkeley's Department of Environmental Science, Policy and Management and an expert on the dietary ecology of primates. "This is particularly true when determining the influence of phytoestrogens on reproductive behavior, which is the whole keystone of natural selection."
 
The study authors cautioned against overinterpreting the power of phytoestrogens in altering behavior, however. They emphasized that estrogenic plant consumption is just one of multiple factors influencing primate hormone levels and behavior. Notably, the primates' own endogenous hormone levels were the stronger predictor of certain behaviors, while phytoestrogens played a secondary role.
 
The researchers noted that the tendency for certain behaviors to occur can be affected by complex interactions between endogenous hormones and phytoestrogens, in addition to factors such as the quality and quantity of food, competition for resources and mates and predation.
 
Nonetheless, previous research in laboratory and agricultural settings found that eating estrogenic plants could disrupt fertility and affect behavior in animals such as rodents, monkeys and sheep. Effects of phytoestrogen consumption in other studies have included more aggression, less body contact, more isolation, higher anxiety and impaired reproduction.
 
The UC Berkeley-led research is the first to observe the connection between estrogenic plant consumption and behavior in a wild primate.
 
To expand on this possibility, Wasserman and his colleagues are now examining the relationship between phytoestrogens and other primate species, including our closest-living relative, the chimpanzee, to determine how common estrogenic plants are in the diets of wild primates.
 
"Human ancestors took most of their diet from wild tropical plants, and our biology has changed little since this time, so similar relationships as those found here are expected to have occurred over our evolutionary history," said Wasserman, now a post-doctoral scholar at McGill University's Department of Anthropology in Montreal, Canada.
 
However, the researchers noted that the red colobus diet contains a high percentage of leaves, while the diet of chimpanzees, other apes and human ancestors consists primarily of fruits. Thus, one of Wasserman's current goals is to compare the presence of phytoestrogens in wild leaves and fruits.
 
"If phytoestrogens make up a significant proportion of a fruit-eating primate's diet, and that consumption has similar physiological and behavioral effects as those observed in the red colobus, then estrogenic plants likely played an important role in human evolution," said Wasserman. "After studying the effects of phytoestrogens in apes and fruit-eating primates, we can then get a better sense of how these estrogenic compounds may influence human health and behavior."
 
Other co-authors of the study are Colin Chapman and Jan Gogarten from McGill University, and Daniel Wittwer and Toni Ziegler from the Wisconsin National Primate Research Center at the University of Wisconsin-Madison.
 
The National Science Foundation and the International Primatological Society helped support this research.

Much ado about nothing. Soy protein will not turn you into a girl or make you want to paint daisies instead of pump iron. Ask Bill Pearl, 4-time Mr. Universe and professional strongman, if soy protein hindered his muscle gains.

he was a juice monkey and only became a vegetarian at age 39...

i am surprised that he's still alive though... (born in 1930)

Because it's now (16 years) a Frankenfood capable of thriving after being doused with herbicide (Roundup).

He stopped using them. And he was a vegetarian when he won his final Mr. Universe title in 1971.

i am happy to see that you can do math... besides, a traditional vegetarian diet is rich in dairy, eggs and fish... still healthy for bodybuilding IMO...

veganism is a disorder...

and soy is shit

What people? Soy ain't the greatest thing on the planet. But, it isn't the evil seed of death that some bodybuilding enthusiasts think it is.

There was a huge marketing push (by the soybean ag board  Roll Eyes) back in the 90's of how great & wonderful soy was.  That was right around the same time it became a GMO frankenfood.  Prior to that, it probably was a good food source.

I have a 4-lb jug of GNC Soy Protein 95 (which I got for $12.50). If making it a "Frakenfood" keeps it at these prices, then make it "ALLLIIIIIVEEEE!!"

I'm just kidding. It's really that cheap, because it expires next month.

You could probably keep it in the freezer for quite awhile yet.  I'd put it in a freezer ziploc and push out as much air as possible.

Retarded people drinking soy milk eating and eating soy veggie burgers like its better than the real thing. And I agree in that its not that bad but to me even the word soy sounds stupid enough not to eat it.

First of all, dating on food is a VOLUNTARY system, with the exception of baby formula and some baby foods.  In some states, dairy must be pulled from shelves on the exp. date. even though unopened things are fine at least 7 days beyond that.

Secondly, there are all kinds of 'dates' out there - sell by, best before, best if used by, use by, packed on, guaranteed fresh, etc.  These dates refer to quality and not safety and are determined by the mfr.

A lot of things are perfectly fine beyond the "exp date", even after they've been opened and I wouldn't hesitate buying something unopened with a near exp. date.

vitamin and mineral content will be reduced, risks of food poisoning increase

call me crazy but i buy fresh food every 2 days and i don't freeze anything...

i buy, cook it and eat it and then repeat...

currently going through 3lbs of boneless chicken breast per day

Last time I bought fresh fruit and vegetables, I didn't see an expiration date.

Try again when you're sober.

fresh grown and gathered fruit and vegetables have way more vitamins and minerals and 3-4 week old shit that was picked green, sprayed and shipped... that's why frozen or canned is a good idea
