Phytoestrogens

[Jimmy P]

Hej MOL,

hvis der sidder en derude, som ved lidt om phytoestrogener (muligvis ikke det danske navn), så ville det være dejligt og tidsbesparende.

Jeg har lige opdaget linser og er blevet ret glad for dem. Ditto på bønner, men dem har jeg spist i længere tid, fra tid til anden. De har jo en kanon ernæringsprofil umiddelbart.

Nu opdager jeg så at der muligvis er et issue vedrørende phytoestrogener (samme som soyabønner?), hvilket ikke rigtigt lyder som noget jeg bliver hverken stærkere eller flottere af.

Er der noget om snakken og skal jeg droppe mine linser/bønner?

mvh

Ps. jeg er selvfølgelig ikke vegetar.

Og hvis der er nogen, der ved noget om Kvinder, linser og bønner i samme sammenhæng, vil jeg da også gerne lige høre det

Moderat indtag af tilberedte bønner/linser skulle næppe betyde noget for ens hormonelle system. Kun soja bønnen indeholder mig bekendt så store mængder phytoøstrogener, at det kan blive problematisk. En ting at overveje er dog indholdet af phytater i bønner, der vil hæmme mineral optaget.

Mvh Andreas

Hypogonadism and erectile dysfunction associated with soy product consumption.

Siepmann T, Roofeh J, Kiefer FW, Edelson DG.

Abstract

Previous research has focused on the beneficial effects of soy and its active ingredients, isoflavones. For instance, soy consumption has been associated with lower cardiovascular and breast cancer risks. However, the number of reports demonstrating adverse effects of isoflavones due to their estrogenlike properties has increased. We present the case of a 19-y-old type 1 diabetic but otherwise healthy man with sudden onset of loss of libido and erectile dysfunction after the ingestion of large quantities of soy-based products in a vegan-style diet. Blood levels of free and total testosterone and dehydroepiandrosterone (DHEA) were taken at the initial presentation for examination and continuously monitored up to 2 y after discontinuation of the vegan diet. Blood concentrations of free and total testosterone were initially decreased, whereas DHEA was increased. These parameters normalized within 1 y after cessation of the vegan diet. Normalization of testosterone and DHEA levels was paralleled by a constant improvement of symptoms; full sexual function was regained 1 y after cessation of the vegan diet. This case indicates that soy product consumption is related to hypogonadism and erectile dysfunction. To the best of our knowledge, this is the first report of a combination of decreased free testosterone and increased DHEA blood concentrations after consuming a soy-rich diet. Hence, this case emphasizes the impact of isoflavones in the regulation of sex hormones and associated physical alterations.
