The dietary supplement world is awaiting some critical guidance regarding new dietary ingredients from the FDA due to arrive by the end of June 2011. In anticipation of this guidance, chatter in the industry has increased, and this has even made the news.
Abstracts & Commentary
Previous studies in vitro and in vivo have shown omega-3 fatty acids may increase the cytotoxicity of chemotherapy agents. While such preliminary evidence points to potentiation of chemotherapy, there is little clinical trial data to date to substantiate these claims. The current abstract strengthens the body of evidence that suggests EPA/DHA may sensitize cancer cells to the cytotoxic effects of chemotherapeutics.
Kefir significantly improved triple antibiotic therapy eradication of <i>H. pylori</i>. Infection was eradicated in more than three-quarters of those patients drinking kefir, compared with only half of those who received antibiotics plus placebo.
Prunes work. That is, prunes appear to do exactly what everyone has always thought they do; they act as a mild laxative. Although some would think this action is obvious, this study by Attaluri et al may be among the first human clinical trial published in the peer reviewed literature that demonstrates prune efficacy.
Levels of DHA were higher among high-grade cases compared with controls. Levels of TFA 18:1 and 18:2 were significantly lower among high-grade cases compared with controls. There were no other significant differences of the remaining phospholipids between control and cancer groups. EPA was not associated with risk of high-grade PCa, and associations were similar for EPA+DHA to that of DHA alone.
The article reported the overall average of the baseline and post treatment nitric oxide levels; the individual results of each of the 23 participants were not included. The cranial therapy was associated with changes in NO levels in exhaled breath.
The prevalence of eczema has increased during the past few decades and continues to rise. Furthermore, childhood eczema is associated with the development of allergy later in life. As a result, there is considerable interest in identifying effective treatments to prevent eczema and, possibly, halt the progression of allergic disease.
Glucosamine is a natural compound that is found in healthy cartilage. Glucosamine sulfate is a normal constituent of glycoaminoglycans in cartilage matrix and synovial fluid. Available evidence from randomized controlled trials supports the use of glucosamine sulfate in the treatment of osteoarthritis, particularly of the knee. It is believed that the sulfate moiety provides clinical benefit in the synovial fluid by strengthening cartilage and aiding glycosaminoglycan synthesis. If this hypothesis is confirmed, it would mean that only the glucosamine sulfate form is effective and non-sulfated glucosamine forms are not effective.
