Concern has arisen over a possible detrimental effect of soy in breast 
cancer patients because of the estrogen-like effects of isoflavones. 
Genistein exhibits a biphasic effect on the growth of MCF-7 cells in 
vitro, 
stimulating proliferation at low concentrations but inhibiting it at 
high 
concentrations. In ovariectomized athymic mice implanted with MCF-7 
cells, both genistein and soy protein stimulate tumor growth in a 
dose-dependent manner. In contrast, in intact mice fed estrogen, 
genistein inhibits tumor growth

Interesting. I have a friend who loves scotch a lot. He doesn't claim 
it is healthful, though.

There are a *lot* of pesticides used in raising soy: acifluorfen, 
bentazon, chlorimuron, dimethenamid, fenoxaprop, fluazifop, flufenacet, 
flumetsulam, flumiclorac, imazaquin, imazethapyr, lactofen, 
metolachlor, metribuzin, pendimethalin, sethoxydim, sulfentrazone, 
thifensulfuron, trifluralin

Rapeseed is the seed of the rape plant.You crush oilseeds in order to 
get meal and oil. Canola is low-erucic acid rape. 

Erucic fatty acid is a *long* chain - 22 carbons - that isn't suitable 
for food; rape oil was always used for industrial purposes, such as 
lubricants, paints, etc. Canola reduces erucic content from over 50% to 
less than 1%.  The essential nutrients of linoleic acids and linolenic 
acid are increased from about 15% and 1% to about 30% and 10%.
Palmitoleic fatty acid is increased from 32% to about 60%.

Trans fatty acids are only formed during the hydrogenation process. 
Linoleic and linolenic acids are especially vulnerable; that's 
basically what you hydrogenate when you harden an oil. Since soy oil 
has the highest level of linoleic and linolenic fatty acids, 
hydrogenated soy oil tends to be higher in trans acids than other 
hydrogenated oils of the same hardness.

I will go along with those who argue that monosaturated oils are 
probably the best for you, but sheesh, olive oil *smells*. Yuck!
