Effect of a low glycemic index diet with soy protein and phytosterols on CVD risk factors in postmenopausal women.

OBJECTIVES: Cardiovascular disease (CVD) is the leading cause of death in women. Hyperlipidemia is a major risk factor for CVD, but research suggests that metabolic syndrome and type 2 diabetes are also key factors in CVD in postmenopausal women. Most dietary programs, however, focus only on hyperlipidemia and not on insulin resistance associated with diabetes and metabolic syndrome. This 12-wk trial compared the effects of a dietary program combining a low glycemic index diet with a functional food delivering 30 g of soy protein and 4 g of phytosterols per day (LGID) with a standard dietary program (American Heart Association Step 1 diet; AHAD) in postmenopausal women. METHODS: Fifty-nine postmenopausal women (average age 54.6 y, range 44-65 y) with a body mass index of 27 to 39 kg/m2 were randomly assigned to the LGID or the AHAD program for 12 wk. Total caloric intake and exercise were matched in each arm. RESULTS: Twenty-seven women completed the LGID program, and 26 completed the AHAD program. The participants on the LGID program showed statistically significant decreases in total cholesterol (15.8%, P = 0.0036 between-group comparison), low-density lipoprotein cholesterol (14.8%, P = 0.004 between-group comparison), and triacylglycerol (44.8%, P = 0.006 between-group comparison). In addition, significant improvements were observed in ratios of total to high-density lipoprotein cholesterol and of triacylglycerol to high-density lipoprotein cholesterol, blood pressure, and Framingham risk assessment for coronary heart disease compared with the AHAD program. CONCLUSIONS: A significantly greater improvement was observed in CVD risk factors in postmenopausal women on the LGID program (incorporating 30 g of soy protein and 4 g of phytosterols per day) than with a standard therapy.

A pilot trial evaluating Meta050, a proprietary combination of reduced iso-alpha acids, rosemary extract and oleanolic acid in patients with arthritis and fibromyalgia.

The aim of this open-label, 8-week observational trial was to investigate the efficacy of Meta050 (a proprietary, standardized combination of reduced iso-alpha-acids from hops, rosemary extract and oleanolic acid) on pain in patients with rheumatic disease. Osteoarthritis, rheumatoid arthritis and fibromyalgia patients were given 440 mg Meta050 three times a day for 4 weeks, which was changed to 880 mg twice a day for the subsequent 4 weeks in the majority of patients. Pain and condition-specific symptoms were assessed using a standard visual analog scale (VAS), an abridged arthritis impact measurement scale (AIMS2) and the fibromyalgia impact questionnaire. Fifty-four subjects with rheumatic disease completed the trial. Following treatment, a statistically significant decrease in pain of 50% and 40% was observed in arthritis subjects using the VAS (p < 0.0001; Wilcoxon-ranked sums) and AIMS2 (p < 0.0001), respectively. Fibromyalgia subject scores did not significantly improve. A decreasing trend of C-reactive protein, a marker for inflammation, was also observed in those subjects who presented with elevated C-reactive protein. No serious side effects were observed. These observations suggest that Meta050 at a dosage of 440 mg three times a day has a beneficial effect on pain in arthritis subjects.

Clinical effects of a proprietary combination isoflavone nutritional supplement in menopausal women: a pilot trial.

BACKGROUND: As they reach menopause, a majority of women living in Westernized countries experience climacteric symptoms. Hormone replacement therapy (HRT) has been used to remediate these symptoms. Recent studies, however, have suggested that HRT may increase the risk of developing breast cancer and cardiovascular disease (CVD). Therefore, many women are looking for alternative treatment options. PURPOSE: This trial was a pilot study to assess the effect of a nutritional supplement containing isoflavones from kudzu and red clover, along with other targeted nutrients on menopausal symptoms and markers of breast cancer and CVD risk. Twenty-five menopausal women suffering from severe hot flushes and night sweats completed a 12-week intervention using this combination isoflavone nutritional supplement. RESULTS: We observed a 46% decrease in reported hot flushes, from an average of 9.7 to 5.2 per day. Quality of life, as assessed by the standardized Greene Questionnaire, showed similar improvement. Two markers of CVD risk, the ratio of total cholesterol to high-density lipoprotein (HDL) cholesterol and homocysteine, showed modest improvement. A proposed marker of breast cancer risk, the ratio of 2-hydroxyestrone to 16 alpha-hydroxyestrone, also showed a statistically significant improvement. CONCLUSIONS: The results of this pilot trial suggests that this combination isoflavone nutritional supplement may significantly relieve the most troubling symptoms of menopause, as well as confer some chemopreventive and cardioprotective benefits.
