Eating Soy as a Kid Reduces Breast Cancer Risk

New research in the journal Cancer Epidemiology, Biomarkers and Prevention found women who ate soy as a child may have a lower risk of developing breast cancer later in life. The study involved 1,600 Asian Americans with or without breast cancer, revealing those women who consumed soy regularly as a child, once a week or more, were 60% less likely to develop breast cancer and regular soy consumption as an adulthood was linked to 25% less risk of breast cancer, compared to women not eating soy; Reuters reports.

Soy is a super food! Previous reports suggest soy helps lower cholesterol and improve artery health of stroke patients and another study showed soy foods reduce the risk of estrogen receptor (ER)-positive tumors and human epidermal growth factor receptor 2 (HER2)-negative tumor, which are associated with breast cancer.

I’ve been on a soy bean kick lately, although the farting makes Yoga interesting. Soymilk is cool too and, despite the obvious conflict of interest, even cows drink soymilk!

ok, i'm officially confused. was just reading frank lipman's book *spent* last night and he says soy/soymilk is bad bad bad. that because the soybeans aren't fermented first and because of the process used to turn them into whatever food they're being turned into, they have toxins which are carcinogenic. also they raise estrogen, which isn't good.

starting to feel like i can't eat anything but vegetables.

Hey Maya-

There's no reason to be confused. Soy and tofu are fine to eat, but like Dr. Fuhrman says, don't eat those processed soy foods, like soy bacon and soy chicken nuggets, and biodiversity is key, eat soy, but also eat plenty of fruits and veggies.

Costco carries frozen, plain edamame. I have been LOVING these as my evening snack! The kids love them, too of course, but they have to ask very nicely for "mom's" treats. :)

Hi Gerry

1) Who is Frank Lippman

2) Is soy milk bad bad bad, or is it more like tofu. I remember the "not milk" guy going on about the carrageenan in some soy drinks, but it's hard to find that guy credible (he is just SO overweight).

Cheers, Steve

Hey Steve-

I don't know who Frank Lippman is.

As for soymilk, in the office here we have soymilk. The organic, unsweetened kind. As for me, I don't eat a lot of soy foods. I eat edamame beans, but as for soymilk, not very often, same with tofu. I rather eat other stuff.

Hi Gerry
I don't eat a lot of soy either, but I do use 'So Nice' unsweetened soy milk in smoothies, and I buy edamame from time to time.

I think soy is mentioned more than other beans basically because it is highest in protein (ie the old you need tons of protein myth is alive and well here).

since kids don't eat a lot of vegetables (mine won't, anyway), i'm not sure how to get calcium into her without soy milk. she'll drink plain soymilk (i buy Silk) and vanilla, but i'm not sure she'd dig unsweetened soymilk. so i guess that's my main concern.

frank lipman is the doctor who wrote *spent.* google it if you're interested. he doesn't have anything to do with this site or dr. f, but he has a similar message about eating whole, unprocessed food (though he's not vegan/vegetarian).

Hi Maya
I did a search on Dr Lipman. Impressive resume, bravely crossing the apartheid line in South Africa when he was younger.

The only comment I could find on soy milk was that most American soy is GM (I buy non-GM myself). I noticed he was a fan of nut milks like almond and cashew, similar to Dr Fuhrman.

Regards, Steve

thanks, steve. i'm going to try some almond milk, etc. i have more research to do, for sure.

well soy oil is also suspected for causing cancer.
the only oil which is quaranteed the most healthy and proove4d factor of longlife is the olive oil and thats it.all the others everyone has different opinion.
just avoid to frie it often as all oils.

mike1970 - March 28, 2009 2:33 AM

and in case of problems like adrenal fatique,fatique,even if caused by stress soy is absolutely forbiden to be taken.just click on adrenal fatique and nutrition and u will find out how good the famous soy oil is for your body.its time i think the myth about the eastern nutrition must stop as i live years in the east and the people here have more heart cholesterol cancer diabetes and so on than any other place in the world perhaps.

why people see the wolf and they search for his steps to find him i really dont know.or actually i know that they are victoms of a system which profits on their aknowledge and desire for a healthy life.
it has been prooved through houndreds years of facts and the last decades scientifically that the mediteranean nutrition is the best combining it with a less stressy life.why its prooved?simply cause people in crete-greece live longer than any other in the planet.and a proove that all the rest is disaster is that as the western life style is beeing adopted this starts to change also there.not to forget the many chemicals which are used in whatever u eat.actually the only way to be safe is to produce what u can in your backyard if u have one.otherwise be ready to have a long perhaps but not quality life be assisted by a lots of medicine so the doctors- medicine cartel survives by leting us what u want but litle from everyhing and make breaks in case u have unhealthy behaviours.

Steve - March 28, 2009 9:24 AM

Well, I did a search on adrenal fatigue, it seemed to be a rather faddish topic to say the least. Lots of 'health food store' type remedies and suggestions to eat nutrient dense fats like butter...
