Wasabi improves memory, flaxseed may reduce the risk of breast cancer, zinc can help to fight yeast infections, light therapy alleviates Alzheimer’s symptoms, and collagen in good for more than just your skin.

Every week we discover inspiring, informative, and sometimes shocking health-related news. From new studies to insightful analysis, here is what you need to know this week:

  • Wasabi may support brain function and increase memory retention. A new Japanese study shows dramatic improvements of 18% in memory scores after 3 months of wasabi treatment. Wasabi may have anti-inflammatory and anti-oxidant properties that support the brain. Nutrients
  • Flaxseed supports components of the gut microbiome that leads to reduced breast cancer risk. “In this study, we found correlations between diets enriched in flaxseed, cecal microbiota composition and miRNA profiles in the mammary gland that regulate many pathways, including those involved in cancer development. This preliminary study supports further research into the role that the microbiota plays in dietary approaches to reduce risk factors associated with disease.” Microbiology Spectrum
  • Zinc has been shown to have a strong effect in fighting yeast infections. An early study shows that zinc-based creams were very effective in reducing re-infections. Larger studies are needed to develop scalable treatments. Science Translational Medicine
  • Light therapy improves the symptoms of Alzheimer’s disease. A new meta-analysis shows that light therapy improved sleep, alleviated depression symptoms, and reduced agitation in patients with Alzheimer’s disease. PLoS ONE
  • Collagen is not only good for the skin but has now also been shown to support tendons and bones. Collagen provides structural support to our connective tissues—including our bones, cartilage, tendons, ligaments, muscles and skin. The American Journal of Clinical Nutrition
