• The potential heart health benefits of polyphenol-rich cocoa powder may be related to a ‘novel mechanism’ of boosting HDL (good) cholesterol, says a new study from Japan.

    Feb 04, 2011
        The majority of research into the potential benefits of cocoa has revolved around the cardiovascular benefits of the flavanols (also known as flavan-3-ols or catechins). While it is known that consumption of cocoa polyphenols may boost HDL cholesterol levels, and decrease LDL cholesterol levels, Japanese researchers state that “the mechanisms responsible for these effects of cocoa on cholesterol metabolism have yet to be fully elucidated”. Here the Japanese researchers checked the affects of Cocoa antioxidants on human tissue.
  • A systematic review of randomized clinical trials shows that the herb Rhodiola rosea improves physical and mental performance and improves mental health

    Feb 03, 2011
    Researchers at the University of Exeter, in the UK critically assessed the current evidence from randomized clinical trials for or against the effectiveness or efficacy of Rhodiola rosea. Systematic literature searches were performed in six electronic databases: AMED (1985-July 2009), CINAHL (1982-July 2009), The Cochrane Library (search in July 2009), EMBASE (1974-July 2009), MEDLINE (1950-July 2009) and Web of Science (searched in July 2009). Eleven randomized clinical trials met the inclusion criteria; all were placebo-controlled.
  • Green Tea reduces the risk of developing coronary artery disease; Americas biggest killer

    Feb 02, 2011
    The objective of this study was to perform a meta-analysis of existing research to determine whether an association exists between tea consumption and protection from coronary artery disease in observational studies. The researchers combed PUBMED and EMBASE databases for studies conducted from 1966 through November 2009. Study-specific risk estimates were combined by using a random-effects model.
  • Three Recent Meta-Analyses; Green Tea Consumption Decreases the Risk Of Breast Cancer

    Feb 01, 2011
        A recent analysis of all existing research on Green Tea consumption shows that drinking more than three cups a day decreases the risk of breast cancer recurrence by 27%. An analysis of case-controlled studies shows that Green Tea consumption decreases the risk of developing breast cancer at any point by 19%. These Chinese researchers find fault with a recent Japanese analysis of studies which found no connection between Green Tea intake and breast cancer in cohort studies citing possible flaws in analytical method although the final outcome of the Japanese analysis also supports the conclusion that Green Tea is ultimately protective for breast tissue against the risk of cancer.
