    Soy Food Intake and Breast Cancer Survival.
    Xiao Ou Shu et al.
    JAMA Vol. 302 No. 22, December 9, 2009; 302(22):2437-2443.

    Results During the median follow-up of 3.9 years (range, 0.5-6.2 years), 444 deaths and 534 recurrences or breast cancer-related deaths were documented in 5033 surgically treated breast cancer patients. Soy food intake, as measured by either soy protein or soy isoflavone intake, was inversely associated with mortality and recurrence. The hazard ratio associated with the highest quartile of soy protein intake was 0.71 (95% confidence interval [CI], 0.54-0.92) for total mortality and 0.68 (95% CI, 0.54-0.87) for recurrence compared with the lowest quartile of intake. The multivariate-adjusted 4-year mortality rates were 10.3% and 7.4%, and the 4-year recurrence rates were 11.2% and 8.0%, respectively, for women in the lowest and highest quartiles of soy protein intake. The inverse association was evident among women with either estrogen receptor-positive or -negative breast cancer and was present in both users and nonusers of tamoxifen.

    Conclusion Among women with breast cancer, soy food consumption was significantly associated with decreased risk of death and recurrence.

Study: Eating Soy Is Safe for Breast Cancer Survivors - TIME - 0 views

  •  
    "The common culprit is soy, a plant that contains chemicals with estrogen-like and anti-estrogenic properties - making it a nutritional minefield for breast cancer survivors. While Western diets are relatively low in soy - compared with the typical diet in Asia, where people eat soy daily - the percentage of Americans consuming soy at least once a week has increased from 15% in 1997 to 28% in 2003. In the meantime, studies on the effect of soy on breast cancer recurrence and mortality have been conflicting, with some showing that it can reduce risk, while others show an elevated rate of recurrent disease among high soy consumers.

    Now the largest study to date of soy's effect on breast cancer suggests that eating soy, even in large amounts, may not be harmful after all, and may even reduce recurrence and death from the disease. But while the findings are intriguing, not all doctors are ready to tout the benefits of tofu

Health benefits of eating fish far outweigh risks from contaminants, report concludes -... - 0 views

    October 17, 2006 | Steve Stiles
    Boston, MA - A review of the literature on the health effects of dietary fish or fish-oil intake has a reassuring message for seafood lovers, anyone eating fish for health reasons, and perhaps most everyone else [1]. Levels of mercury and other contaminants in commercially bought fish are low, and their potential risks are overwhelmed by likely reductions in cardiovascular mortality, according to a report in the October 18, 2006 issue of the Journal of the American Medical Association.

    "The main message is really that everybody should be eating one or two servings of fish or seafood per week for their health," Dr Dariush Mozaffarian (Harvard School of Public Health, Boston, MA) told heartwire.

    In his analysis, coauthored with Dr Eric B Rimm (Brigham and Women's Hospital, Boston, MA), regular "modest" intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the two long-chain n-3 polyunsaturated fatty acids (PUFAs) abundant in finfish and shellfish (collectively referred to as "fish" in the article), is associated with a 36% drop in coronary disease mortality (p<0.001) and a 17>

    Those potential benefits are immense compared with the highly publicized but apparently low health risks associated with methylmercury, dioxins, and polychlorinated biphenyls (PCBs) that have been found in some fish species, they write. The evidence suggests a potential for neurodevelopmental deficits from early exposure to methylmercury, but the risk is likely diminished by limiting intake of fish with high methylmercur

    A phase 2 trial exploring the effects of high-dose (10,000 IU/day) vitamin D(3) in breast cancer patients with bone metastases.

    Cancer. 2009 Nov 13. [Epub ahead of print]
    PMID: 19918922
    DOI: 10.1002/cncr.24749

    METHODS:
    Patients with bone metastases treated with bisphosphonates were enrolled into this single-arm phase 2 study. Patients received 10,000 IU of vitamin D3 and 1000 mg of calcium supplementation each day for 4 months. The effect of this treatment on palliation, bone resorption markers, calcium metabolism, and toxicity were evaluated at baseline and monthly thereafter.


    CONCLUSIONS:
    Daily doses of 10,000 IU vitamin D3 for 4 months appear safe in patients without comorbid conditions causing hypersensitivity to vitamin D. Treatment reduced inappropriately elevated parathyroid hormone levels, presumably caused by long-term bisphosphonate use. There did not appear to be a significant palliative benefit nor any significant change in bone resorption. Cancer 2010. © 2009 American Cancer Society.

High doses of vitamin D could cut relapse rate among MS sufferers - Times Online - 0 views

  •  
    "Powerful new evidence about the ability of vitamin D to stem a wide range of diseases has brought the prospect of a nationwide programme to prescribe it in Scotland as a dietary supplement significantly closer.

    Reports at the weekend suggested that experts were increasingly convinced that the so-called sunshine drug - whose significance was first revealed in detail by The Times last year - could make a difference to the country's appalling health record.

    New research suggests that high doses of vitamin D could dramatically cut the relapse rate in people with multiple sclerosis. According to scientists in Canada, more than a third of sufferers taking high levels of supplement

    Safety of vitamin D3 in adults with multiple sclerosis.
    Kimball SM, Ursell MR, O'Connor P, Vieth R.
    Am J Clin Nutr. 2007 Sep;86(3):645-51.
    PMID: 17823429

    Conclusions: Patients' serum 25(OH)D concentrations reached twice the top of the physiologic range without eliciting hypercalcemia or hypercalciuria. The data support the feasibility of pharmacologic doses of vitamin D3 for clinical research, and they provide objective evidence that vitamin D intake beyond the current upper limit is safe by a large margin.

    "Dr. Jodie Burton is the acting principal investigator (PI) of the dose-escalation trial of oral vitamin D3 with calcium supplementation in patients with multiple sclerosis with Dr. O'Connor. She started the trial as his fellow, while doing an additional 2 years of training in MS specifically after she received her neurology certification. She completed her fellowship training in 2007. Now she is staff doing clinical research and continuing with the vitamin D trial. As of August 2009, she will be Assistant Professor in Neurology in the Department of Clinical Neuroscience in Calgary and at the University of Calgary. She will be part of the MS team there with Dr. Luanne Metz and the MS group.

    Please scroll down for an abstract of the trial:
    A Phase I/II dose-escalation trial of oral vitamin D3 with calcium supplementation in patients with multiple sclerosis."

    Conclusions:
    High-dose VD3 (~10 000 IU/day, possibly higher) in MS is safe and tolerable, with evidence of clinical improvement."

High Doses of Vitamin D Cut MS Relapses - 0 views

  •  
    "April 28, 2009 (Seattle) -- High doses of vitamin D dramatically cut the relapse rate in people with multiple sclerosis, a study shows.

    Sixteen percent of 25 people with multiple sclerosis (MS) given an average of 14,000 international units (IU) of vitamin D a day for a year suffered relapses, says Jodie Burton, MD, a neurologist at the University of Toronto. In contrast, close to 40% of 24 MS patients who took an average of 1,000 IU a day -- the amount recommended by many MS specialists -- relapsed, she says.

    Also, people taking high-dose vitamin D suffered 41% fewer relapses than the year before the study began, compared with 17% of those taking typical doses.

    People taking high doses of vitamin D did not suffer any significant side effects, Burton tells WebMD."

Stevia, Sweetener, Artificial Sweeteners - Dr. Weil - 0 views

  •  
    Stevia comes from an herb in the chrysanthemum family called Stevia rebaudiana. It is native to Paraguay, also grows in Brazil and Argentina, and is cultivated in China. The leaves have been used for centuries by native peoples to make sweet teas, or to sweeten other foods, with no evidence of harm. It is available in the United States, and the European Union as a dietary supplement and is sold here in whole-leaf form or as stevioside, the extracted sweet principle, sold as a granular white powder. The powder has very few calories but is so sweet that to use it, you must dissolve it in water, then dispense the solution by drops. A teaspoon of the liquid is equivalent in sweetness of a whole cup of sugar. Stevia is safe for diabetics and is widely used as a nonnutritive sweetener around the world.

FDA Clears Use of Herb As Sweetener - WSJ.com - 0 views

  •  
    The Food and Drug Administration has declared a natural zero-calorie sweetener derived from the herb stevia safe for use in foods and beverages, clearing a path for Coca-Cola Co., PepsiCo Inc. and other companies to market it in a variety of products.

    Coke will introduce a reduced-calorie version of Sprite, called Sprite Green, and some Odwalla juice drinks with the new sweetener this month. Pepsi will launch three flavors of a zero-calorie SoBe Lifewater next week, and an orange-juice drink called Trop50, containing half the calories and sugar of orange juice, in March.
