Researchers from the University of Florida gave 52 healthy adults between the ages of 21 and 42 a four-week supply of dried shiitake mushrooms. Participants then ate one 4-ounce serving of shiitake mushrooms every day for four straight weeks. Researchers controlled for several variables:

  • No vegans are vegetarians were studied
  • Subjects could not drink tea or take antioxidant vitamins or probiotics before the study
  • Participants were instructed to limit alcohol to 14 or fewer glasses per week so that immune-enhancing activity wasn’t adversely impacted
  • Volunteers were allowed no more than 7 servings of fruits and vegetables per day

At the end of four weeks participants displayed better gamma delta T-cells and fewer inflammatory proteins.

Lead researcher Sue Percival explains: “If you eat a shiitake mushroom every day, you could see changes in their immune system that are beneficial. We’re enhancing the immune system, but we’re also reducing the inflammation that the immune system produces.”
