  "account": "Researchers from Trinity College Dublin and University College Dublin have discovered that a yeast-based dietary supplement called yeast beta-glucan can boost the immune system's ability to fight cancer in mice. The study, published in the scientific journal Cell Reports, suggests that the supplement can reprogram early-stage immune cells in the bone marrow to produce stronger anti-tumor responses. This effect was observed in obese mice, indicating that the supplement could potentially help restore immune function lost due to obesity. The researchers fed the mice a standard or high-fat diet supplemented with yeast beta-glucan for 4-12 weeks, after which they exposed the animals to various types of cancer cells. The study also tested whether the supplement could counteract immune dysfunction caused by obesity and whether its protective effects persisted after weight loss. The findings demonstrate that consuming yeast beta-glucan in the diet can trigger trained immunity by altering bone marrow stem cells, a process that previous studies achieved using injections. The researchers believe that yeast beta-glucan could serve as a safe and practical candidate for future dietary intervention studies in humans dealing with obesity, chronic infections, and weakened immune function.",
  "summary": "A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.",
