A new study finds that the common yeast Candida albicans, a type of fungus, can cross the blood-brain barrier and trigger an inflammatory response leading to the formation of granuloma-type structures and temporary mild memory impairments in mice. These granulomas share features with plaques found in Alzheimer’s disease.

A randomized trial by Vanderbilt-Ingram Cancer Center researchers indicates that magnesium optimizes vitamin D status, raising it in people with deficient levels and lowering it in people with high levels.

13 December 2018 - The Conversation - Vegan diets are adding to malnutrition in wealthy countries

Eating a plant-based diet may lower the risk of chronic disease and is good for the environment, but poorly planned vegan diets that do not replace the critical nutrients found in meat, can lead to serious micronutrient deficiencies.

13 December 2018 - Nutraingredients - Omega 3’s effect on brain blood flow could battle memory decline in ageing

Omega-3 polyunsaturated fatty acid (PUFA) supplementation has the potential to enhance neural blood flow, possibly preventing memory decline caused by restricted blood flow or brain cell inflammation.
