Flaxseed shows potential to reduce
Data from a new Mayo Clinic (http://mayoclinic.edu) study suggest that dietary therapy
using flaxseed can decrease hot flashes in postmenopausal women who do not take estrogen.
The findings from the pilot study are published in the summer 2007 issue of the Journal of
the Society for Integrative Oncology. A hot flash is often described as a flush of intense
warmth across much of the body that may be accompanied by sweating, reddening of the skin,
or, occasionally, cold shivers. Hot flashes occur in varying frequency and duration, even
during sleep, and often cause or accompany sleep deprivation, anxiety and irritability.
Hot flashes are a bothersome issue for women experiencing menopause, says
Sandhya Pruthi, M.D., Mayo Clinic breast health (http://cancercenter.mayo.edu/) specialist
and the studys primary investigator. We hope to find more effective
nonhormonal options to assist women, and flaxseed looks promising.
Lignans likely to lessen breast cancer
Ms Williamsons study involved two trials with healthy postmenopausal women. The
answer to reducing your risk of breast cancer could very well come down to flaxseeds,
according to the latest research by an RMIT University postgraduate researcher.
Is flaxseed oil a risk for men?
The author speculated that the lignans in flaxseed are a major component of its
anti-cancer effects and that the lack of lignans in most brands of flaxseed oil may
explain why flaxseed oil is not beneficial. Until we know more about the risk flaxseed oil
appears to present, I recommend that men avoid it, or at least stick to brands that put
the lignans back in.
Minder darmpoliepen door
Een tot dusver obscure groep verbindingen in plantaardige producten halveert de kans op
darmpoliepen. Dat blijkt uit het promotieonderzoek van dr. Anneleen Kuijsten aan
Wageningen Universiteit. De door Kuijsten onderzochte stoffen zijn lignanen. Ze zitten in
meergranenbrood, thee, groenten en fruit. Ze vallen onder de polyfenolen, een grote groep
verbindingen in plantaardige voedingsmiddelen waarvan onderzoekers vermoeden dat ze
beschermen tegen ziekten. Of lignanen dat ook doen is nog steeds niet duidelijk, maar op
basis van Kuijstens onderzoek zou je dat wel verwachten.
Heart Healthy Flax Seed may also be
beneficial in promoting a better mood
Dr. Sarah M. Conklin, a postdoctoral scholar in the department of psychiatry at the
University of Pittsburgh School of Medicine reported that omega-3 polyunsaturated fatty
acids, found in salmon and flax seed may affect parts of the brain related to emotion.
Plant estrogens may help cut cancer
French researchers say a diet rich in lignans may help prevent breast cancer in older
Dietary Lignan Intake and
Postmenopausal Breast Cancer Risk by Estrogen and Progesterone Receptor Status
High dietary intakes of plant lignans and high exposure to enterolignans were associated
with reduced risks of ER- and PR-positive postmenopausal breast cancer in a Western
population that does not consume a diet rich in soy.
The facts on flax
EFAs are termed essential because they cannot be produced by the body and must be obtained
from the diet. They are incorporated into the membranes of our body cells to keep them
fluid and allow entry into cells of important nutrients as well as the removal of toxins.
