    Vitamin D and Blood Glucose Management

    As summer approaches in the Northern Hemisphere, we look forward to spending more time outdoors. This is good because our skin can synthesize vitamin D when exposed to sunlight. With most people spending most of their days indoors, serum 25(OH)D concentrations are known to decrease through the fall and winter months.

    Omega-3 Fatty Acids Linked with Joint Health and Rheumatoid Arthritis

    Every 1% increase in plasma phospholipid eicosapentaenoic acid (EPA) concentration (% of total fatty acids) is associated with a 12% increase in the probability of remission in rheumatoid arthritis, according to a new Br J Nutrition study.

    The patients had been diagnosed with rheumatoid arthritis within the past 12 months. They were randomized to receive 3.2g EPA + 2.3 g docosahexaenoic acid (DHA) daily (high-dose) or 0.21 g EPA + 0.19g DHA daily (low-dose) and results are presented after 1 year.
