And Now for some news ….
Neuroprotection by spice-derived Nutraceuticals
Numerous lines of evidence indicate that chronic inflammation plays a major role in the development of various neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, brain tumor, and meningitis.
Why these diseases are more common among people from some countries than others is not fully understood, but lifestyle factors have been linked to the development of neurodegenerative diseases.
For example, the incidence of certain neurodegenerative diseases among people living in the Asian subcontinent, where people regularly consume spices, is much lower than in countries of the western world.
Extensive research over the last 10 years has indicated that nutraceuticals derived from such spices as turmeric, red pepper, black pepper, licorice, clove, ginger, garlic, coriander, and cinnamon target inflammatory pathways, thereby may prevent neurodegenerative diseases.
How these nutraceuticals modulate various pathways and how they exert neuroprotection are the focus of this review published in the journal Molecular Neurobiology.
As always, discuss all Nutritional Recommendations with your Qualified Health Care Provider.

Vitamin D and Insulin Resistance and Bone Loss
A study published in the journal European Journal of Clinical Nutrition looked at the association between vitamin D status and insulin resistance (IR) has been less studied among Asians, and it remains elusive whether calcium could modify such an association.
The authors of the study examined the association of serum 25-hydroxyvitamin D (25(OH)D) concentrations with insulin resistance markers and the potential effect modification by calcium intake among a Japanese population.
The study concluded that the authors’ findings suggest that low vitamin D status is associated with insulin resistance among Japanese adults.
In another Vitamin D study – The effect of vegan diet on bone loss has not been studied. The aim of this study was to examine the association between veganism and bone loss in postmenopausal women.
The study was designed as a prospective longitudinal investigation with 210 women, including 105 vegans and 105 omnivores. Femoral neck (FN) bone mineral density (BMD) was measured in 2008 and 2010 by dual-energy X-ray absorptiometry (Hologic QDR4500).
Among the 210 women who initially participated in the study in 2008, 181 women had completed the study and 29 women were lost to follow-up. Lower body weight, higher intakes of animal protein and lipid, and corticosteroid use were associated with greater rate of bone loss. There were no significant differences in βCTX and PINP between vegans and omnivores. The prevalence of vitamin D insufficiency in vegans was higher than in omnivores.
The study concluded that the Vegan diet did not have adverse effect on bone loss and fracture. Corticosteroid use and high intakes of animal protein and animal lipid were negatively associated with bone loss.
As always, discuss all Nutritional recommendations with your Qualified Health Care Provider.

Review of the Hypoalgesic Effects of Exercise
The purpose of a recent article in the Journal of Pain was to examine the effects of acute exercise on pain perception in healthy adults and adults with chronic pain using meta-analytic techniques.
Specifically, studies using a repeated measures design to examine the effect of acute isometric, aerobic, or dynamic resistance exercise on pain threshold and pain intensity measures were included in this meta-analysis.
The results suggest that all 3 types of exercise reduce perception of experimentally induced pain in healthy participants, with effects ranging from small to large depending on pain induction method and exercise protocol.
In healthy participants, the mean effect size for aerobic exercise was moderate, while the mean effect sizes for isometric exercise and dynamic resistance exercise were large.
In chronic pain populations, the magnitude and direction of the effect sizes were highly variable for aerobic and isometric exercise and appeared to depend on the chronic pain condition being studied as well as the intensity of the exercise.
While trends could be identified, the optimal dose of exercise that is needed to produce hypoalgesia could not be systematically determined with the amount of data available.
This article presents a quantitative review of the exercise-induced hypoalgesia literature. This review raises several important questions that need to be addressed while also demonstrating that acute exercise has a hypoalgesic effect on experimentally induced pain in healthy adults, and both a hypoalgesic and hyperalgesic effect in adults with chronic pain.
