Dietary supplement users take these products as just one component of a larger effort to develop a healthier lifestyle, according to a newly published review in Nutrition Journal, a peer-reviewed scientific publication. The review, “Health Habits and Other Characteristics of Supplement Users” (Nutrition Journal. 2014, 13:14), co-authored by Council for Responsible Nutrition (CRN) consultant Annette Dickinson, Ph.D., and CRN's senior vice president, scientific and regulatory affairs, Duffy MacKay, N.D., examined data from 20 peer-reviewed scientific journal articles and found that, “overall, the evidence suggests that users of dietary supplements are seeking wellness and are consciously adopting a variety of lifestyle habits that they consider to contribute to healthy living.” CRN
Nutritional supplement improves cognitive performance in older adults, study finds

Heart health through gut health
A new study, "Effect of probiotics on biomarkers of cardiovascular disease: implications for heart-healthy diets," published in the January issue of Nutrition Reviews, examined 26 clinical studies and two meta-analyses to assess the potential of probiotics in reducing LDL-cholesterol.
Of the probiotics examined, L. reuteri NCIMB 30242 (Cardioviva™) was found to best meet therapeutic lifestyle change (TLC) dietary requirements by:
- Significantly reducing LDL (bad) cholesterol and total cholesterol, with robustness similar to that of existing TLC dietary options,
- Improving other coronary heart disease risk factors, such as inflammatory biomarkers, and
- Having "generally recognized as safe" (GRAS) status. Eurekalert!
A study published in The American Journal of Medicine reveals that a whole diet approach, which focuses on increased intake of fruits, vegetables, nuts, and fish, has more evidence for reducing cardiovascular risk than strategies that focus exclusively on reduced dietary fat. This new study explains that while strictly low-fat diets have the ability to lower cholesterol, they are not as conclusive in reducing cardiac deaths. By analyzing major diet and heart disease studies conducted over the last several decades, investigators found that participants directed to adopt a whole diet approach instead of limiting fat intake had a greater reduction in cardiovascular death and non-fatal myocardial infarction.

Intravenous vitamin C may boost chemo's cancer-fighting power
Large doses of intravenous vitamin C have the potential to boost chemotherapy's ability to kill cancer cells, according to new laboratory research involving human cells and mice. Vitamin C delivered directly to human and mouse ovarian cancer cells helped kill off those cells while leaving normal cells unharmed, University of Kansas researchers report.
In follow-up human trials, a handful of cervical cancer patients given intravenous vitamin C along with their chemotherapy reported fewer toxic side effects from their cancer treatment, according to the study published in the Feb. 5 issue of Science Translational Medicine. MedicalXpress
Study shows yogurt consumption reduces the risk of type 2 diabetes
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that higher consumption of yoghurt, compared with no consumption, can reduce the risk of new-onset type 2 diabetes by 28%. Scientists at the University of Cambridge found that in fact higher consumption of low-fat fermented dairy products, which include all yoghurt varieties and some low-fat cheeses, also reduced the relative risk of diabetes by 24% overall.
