Lignans, which are the type of phytoestrogens in flaxseed, can change estrogen metabolism. In postmenopausal women, lignans can cause the body to produce less active forms of estrogen. This is believed to potentially reduce breast cancer risk. Roasting flaxseeds on a low flame can preserve their nutrients, but roasting at a higher temperature or for a long time can damage their cell structure and make them more sensitive to thermal treatment. Roasting at temperatures of 160-220 °C can also negatively impact the nutritional quality of flaxseed oil. However, roasting can also destroy toxins in unripe or raw flaxseeds.
I add flax powder into my cooking as a thickener.
What about it’s oestrogen?
Does roasting help and will there be nutrients left after roasting?
