4 – Flaxseed and prostate cancer
Lignans have also slowed tumor growth in prostate cancer patients.
Ground flaxseed seems to be quite helpful not just for preventing prostate cancer, but also for men who already have prostate cancer. As well as the phytoestrogen effect, the lignans in flaxseed adhere to hormone receptors and promote the removal of testosterone. In men having prostate cancer, a low fat diet supplemented with 30 grams of ground flaxseed reduces serum testosterone by 15 %, slows down the growth rate of cancer cells, and increases the death rate of cancer cells.
