SHIITAKE MUSHROOM

Cliff Notes:
  • A powerful mushroom packed with B Vitamins, high antioxidant and stress-fighting nutrients.
Brain Effects:
  • Shiitake Mushrooms has been shown, when take on a consistent basis, to support proper adrenal function and aid with the neurotransmitter function; helping to aid energy and break through ‘brain fog.’
Research:
A variety of preclinical and clinical studies suggest that consumption of certain mushroom species, as either food or extracts, or consumption of specific constituents from mushrooms may reduce the risk of certain diseases. Although Roupas et al. reviewed evidence for a range of health effects, the following sections touch on evidence pertaining to mushrooms and cognition, cancer, weight management, and oral health, in keeping with the summit presentations.
Very preliminary experimental animal data suggest a protective effect of ergocalciferol-enriched mushrooms on β-amyloid peptide toxicity in the brain and mild cognitive impairment (both precursors to dementia) in mice. The findings warrant replication and further research on the potential role for mushroom consumption in delaying the onset of dementia and Alzheimer disease. (1)

Recent research has highlighted the potential impact of nutritional factors and individual micronutrients on the brain and on cognitive performance, especially in older adults. The B vitamins, folate, B12, and B6, are of particular interest because even subclinical deficiencies in these vitamins are thought to be relatively common in the general population and in older adults in particular. Recent cross-sectional and longitudinal studies have provided evidence for an association between these B vitamins and many aspects of cognitive performance and have raised the possibility that even subclinical differences in nutritional status may have a subtle influence on aspects of cognitive performance, especially in older adults and in clinical populations. Preliminary evidence also indicates the effectiveness of supplementation in enhancing cognitive performance in older adults. Important considerations for future research include the use of placebo-controlled intervention studies, sensitive outcome measures of cognitive performance, and exploration of bioavailability and dose-response relationships.
