We Need Our D

1 Lose Weight to Boost Vitamin D Levels

We all know the importance of optimal vitamin D levels. Vitamin D promotes calcium absorption, protects older adults from osteoporosis, influences cell growth, neuromuscular and immune function, and reduces inflammation. Studies have shown a possible link between a vitamin D deficiency and chronic diseases, including cancer and heart disease. Now, a new, long-term study by researchers at Fred Hutchinson Cancer Research Center indicates that overweight or obese women with low vitamin D levels who lose more than 15 percent of their body weight experience significant increases in circulating levels of this fat-soluble nutrient. It’s suspected that vitamin D, which is stored in fat deposits, is released into the blood and available for use throughout the body after weight loss.

Ziram Implicated for First Time

2 Pesticide by Workplace Linked to Parkinson's

Ziram, a pesticide, has been implicated in the pathology of Parkinson's disease as researchers have found that those working near fields where the pesticide was spray had increased risk of the disease. Study subjects included teachers, firefighters and clerks who worked near sprayed fields in California's Central Valley. Researchers discovered that combined exposure to ziram, the fungicide maneb and the herbicide paraquat near any workplace caused a threefold increase in Parkinson's risk. Combined exposure to ziram and paraquat was linked with an 80 percent increased risk. While paraquat and maneb had been previously implicated with an increase in Parkinson's risk, this is the first study to implicate ziram. The study results were published online in European Journal of Epidemiology.

Stroke Belt

3 Southerners High Risk for Cognitive Decline

Those who live in the Stroke Belt, the area of the country with a significantly elevated stroke mortality rate, also have a greater incidence of cognitive decline. The Stroke Belt lies primarily in the Southern US, covering the states Alabama, Arkansas, Georgia, Louisiana, Mississippi, North and South Carolina, and Tennessee. Modifiable risk factors such as high blood pressure and obesity not only increase the risk for stroke (stroke mortality is 50% higher than in the remaining US regions), but also greatly increase the risk of decreased cognitive function. To come to this conclusion, researchers from the CDC used data from the REGARDS study which recruited over 30,000 adults over a period of five years. The findings are published in the Annals of Neurology.

Increases Forward Movement

4 Vitamin D Increases Sperm Motility

Researchers in Denmark has found that vitamin D’s role in male fertility involves movement and function. Sperm from 300 healthy men demonstrated that higher serum vitamin D levels increased the percentage of motile sperm. It is too premature to suggest that vitamin D supplementation will improve male fertility but this is the first study that may explain its importance for male fertility in both animals and humans. This study is of particular interest to the Danish because there is a high level of fertility problems linked to low semen quality in men. Randomized-controlled clinical trial comparing vitamin D supplements to placebos will have to be conducted in infertile men to determine if it improves their reproduction.
