Flax Hull Lignans

 

 

FLAX HULL LIGNANS INFORMATION

FLAX LIGNANS (SDG) -- Flax Hulls Linum usitatissimum.  

We can offer beautiful quality concentrated flax hull lignans, containing large concentrations of Lignans (SDG).   Lignans are a group of phytonutrients found in seeds and grains.   Flaxseed is known for being the plant containing the highest concentration of Lignans known as SDG (secoisolariciresinol diglycoside).

Most of the lignans in the flax seed are located in the hull that encased the seed.   Our product contains only pure organic flax hulls, which have been mechanically separated from the flax seed.   The resulting product is said to contain 70 times the amount of SDG lignans per gram as compared to the traditional ground up seed.

Studies have shown these SDG lignans to be effective in a variety of health complications.   Much extensive study has been done on the effects of flax lignans on certain diseases such as Prostate cancer, Skin cancer, Melanoma, Diabetes, Lupus and many more. Being Phytoestrogens, SDG lignans have also been reported to be effective in balancing hormone related problems in women.   These have included breast tenderness, sweating, vaginal dryness, bloating, hot flashes and uneven menstrual cycles and PMS symptoms.

SDG Lignans Information:

Reactive oxygen species (ROS) have been implicated in the development of diabetes mellitus.   SDG isolated from flaxseed is an antioxidant.   An investigation was made of the effects of SDG on the development of diabetes in rats, to determine if SDG can prevent/reduce the development of diabetes and if this prevention/reduction is associated with reduction in oxidative stress.   RESULTS: SDG prevented the development of diabetes by 75%.   (Prasad K, et a, Mol Cell Biochem, 206(1-2): 2000; Prasad K. Mol Cell Biochem, 209(1-2): 89.2000)

Flaxseed SDG may have a therapeutic role in lupus nephritis.   (Clark W. et al Lupus, 9(6): 429, 2000)

Asian men have a much lower incidence of prostate cancer and possibly of benign prostatic hyperplasia (BPH) than Western counterparts.   Vegetarian men have a lower incidence of prostate cancer than omnivorous males.   Plant lignans give rise to the mammalian lignans, enterodiol and enterolactone; the richest source is linseed (flaxseed).   In addition to their oestrogenic activity, these plant compounds can interfere with steroid metabolism and bioavailability, and also inhibit enzymes, such as tyrosine kinase and topoisomerase, which are crucial to cellular proliferation and hence may contribute to lower incidences of prostrate cancer.   (Eur Urol, 35(5-6): 377, 1999)

Dietary estrogens, such as lignan-rich flaxseed, are similar in structure to endogenous sex steroid hormones and act in vivo to alter hormone metabolism and reduce subsequent cancer risk in postmenopausal women.   (Hutchins A, Cancer Epidemiol Biomarkers Prev, 9(10): 1113, 2000)

Research suggests that SDG reduces hypercholesterolemic atherosclerosis and that this effect is associated with a decrease in serum cholesterol, LDL-C, and lipid peroxidation product and an increase in HDL-C and antioxidant reserve.   (Prasad K. Circulation, 99(10): 1355, 1999)

Phytoestrogens are diphenolic compounds that are present in several plants eaten by human beings.   Flaxseed is a particularly abundant source of phytoestrogens.   When ingested in relatively large amounts, phytoestrogens have been shown to have significant estrogen agonists/antagonists effects in animals and humans.   There is epidemiological, laboratory and clinical evidence which indicates that phytoestrogens, like certain selective estrogen receptor modulators, have an antiproliferative effect on the breast, and positive effects on the lipoprotein profile and bone density.   They might also improve some of the climacteric symptoms.   (Brzezinski A & Bebi A. Eur J Obstet Gynecol Reprod Biol. 85(1): 47, 1999)

Flaxseed is high in secoisolariciresinol diglycoside (SDG), the precursor of mammalian lignans, which can affect mammary gland structure.   Lifetime or gestation and lactation exposure to 5 or 10% flaxseed induce structural changes in the mammary gland that may potentially reduce mammary cancer risk.   (Tou J & Thompson L. Carcinogenesis, 20(9): 1831, 1999)

Flaxseed and SDG, regardless of dose, appeared to delay the progression of MNU-induced mammary tumorigenesis.   (Rickard S. et al, Nutr Cancer; 35(1): 50, 1999)

Because flaxseed and its lignans are colon cancer protective, it is concluded that, in contrast to other studies, beta-glucuronidase activity may play a beneficial role in their presence by increasing mammalian lignan absorption and enterohepatic.   (Jenab M, et al, Nutr Cancer, 33(2): 154, 1999)

Dietary supplementation with secoisolariciresinol diglycoside (SDG), a lignan precursor isolated from flaxseed, significantly reduced pulmonary metastasis cells and inhibited the growth of metastatic tumors that formed in the lungs.   (Li D. et al, Cancer Lett, 142(1): 91, 1999)

Flaxseed the richest source of lignans reduces metastasis and inhibits the growth of the metastatic secondary tumors in animals.   Flaxseed may be a useful nutritional adjuvant to prevent melanoma metastasis in cancer patients.   (Yan L, et al, Cancer Lett, 124(2): 181, 1998)

Flaxseed contains lignans that have antioxidant activities and inhibit platelet-activating factor (PAF).   Pretreatment with flaxseed attenuated emdotoxin induced cardiac dysfunction and cellular damage.   Flaxseed antioxidant and anti-PAF agents may be effective in the treatment of ET shock.   (Pattanaik U & Prasad K, J Cardiovasc Pharmacol Ther, 3(4): 305. 1998)

The mammalian lignans enterolactone (EL) and enterodiol (ED) derived from precursors in foods, particularly flaxseed, have been shown to reduce the mammary tumor growth due to their antiestrogenic properties.   Lignans are growth inhibitors of colon tumor cells and they may act through mechanism(s) other than antiestrogenic activity.   (Sung M, et al, Anticancer Res 18(3A: 1405, 1998)

Flaxseed, the richest source of mammalian lignan precursors, such as secoisolariciresinol diglycoside (SD), has been shown over the short term to decrease some early markers of colon cancer risk.   This study determined that flaxseed has a colon cancer protective effect, that it is due, in part to SD and that the protective effects of flaxseed is associated with increase beta-glucuronidase activity.   (Jenab M & Thompson L, Carcinogenesis, 17:1343, 1996)

Flaxseed, a rich source of mammalian lignan precursor secoisolariciresinol-diglycoside _SD) and alpha-linolenic acid (ALA), has been shown to be protective at the early promotion stage of carcinogensis.   In conclusion, the SD lignans in flaxseed appears to be beneficial throughout the promotional phase of carcinogenesis whereas the oil components is more effective at the stage when tumors have already been established.   (Thompson L, et al, Carcinogenesis, 17:1373, 1996)

Flaxseed lignans have antitumor, antimitotic, antioxidant and weak estrogenic activity, are potentially the richest source of phytoestrogens in the human diet and may be linked to a low incidence of breast and colon cancer.   Secoisolariciresinol was discovered to be a very potent antioxidant similar to BHA.   No toxicity was found in the lignans.   (Obermeyer W, et al (US Food and Drug Administration, center for Food Safety and Applied Nutrition, Div. Contaminants Chem., Natural Products Branch), Meeting Of The Federation Of American Societies For Experimental Biology On Experimental Biology March/April, 1993, Faseb J (Fed Am Soc Exp Biol), A863, 1993)

Vitamin E-deficient diets containing 5 to 20% ground flaxseed protected mice against the malarial parasite Plasmodium voelii as shown by decreased parasitemia and enhanced survival.   (Levander O, et al, [USDA/ARS Human Nutrition Research Center, Vitamin Mineral Nutrition Laboratory], Nutrition Research, 11, 1991)
