Flaxseed shows potential to reduce hot flashes

Data from a new Mayo Clinic ( 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 ( specialist and the study’s primary investigator. “We hope to find more effective nonhormonal options to assist women, and flaxseed looks promising.”

Minder darmpoliepen door beschermende plantenstof

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.
