New research is showing the profound benefits—for longevity and fighting disease—of intermittent fasting
NEW YORK (PRWEB) AUGUST 22, 2019
Fasting regimens have gained public and scientific interest in recent years, but fasting shouldn’t be dismissed as a fad. In a study published in Cell, Mount Sinai researchers found that fasting reduces inflammation and improves chronic inflammatory diseases without affecting the immune system’s response to acute infections.
While acute inflammation is a normal immune process that helps fight off infections, chronic inflammation can have serious consequences for health, including heart disease, diabetes, cancer, multiple sclerosis, and inflammatory bowel diseases.
“Caloric restriction is known to improve inflammatory and autoimmune diseases, but the mechanisms by which reduced caloric intake controls inflammation have been poorly understood,” said senior author Miriam Merad, MD, PhD, Director of the Precision Immunology Institute at the Icahn School of Medicine at Mount Sinai.
Working with human and mouse immune cells, Dr. Merad and colleagues showed that intermittent fasting reduced the release of pro-inflammatory cells called “monocytes” in blood circulation. Further investigations revealed that during periods of fasting, these cells go into “sleep mode” and are less inflammatory than monocytes found in those who were fed.
“Monocytes are highly inflammatory immune cells that can cause serious tissue damage, and the population has seen an increasing amount in their blood circulation as a result of eating habits that humans have acquired in recent centuries,” said Dr. Merad.
“Considering the broad spectrum of diseases that are caused by chronic inflammation and the increasing number of patients affected by these diseases, there is an enormous potential in investigating the anti-inflammatory effects of fasting,” said first author Stefan Jordan, PhD, a postdoctoral fellow in the Department of Oncological Sciences at the Icahn School of Medicine at Mount Sinai.
Researchers plan to continue trying to decipher the molecular mechanisms by which fasting improves inflammatory diseases, which could lead to novel preventive therapeutic strategies for the treatment of many human diseases.

The Health System includes approximately 7,480 primary and specialty care physicians; 11 joint-venture ambulatory surgery centers; more than 410 ambulatory practices throughout the five boroughs of New York City, Westchester, Long Island, and Florida; and 31 affiliated community health centers. The Icahn School of Medicine is one of three medical schools that have earned distinction by multiple indicators: ranked in the top 20 by U.S. News & World Report’s “Best Medical Schools”, aligned with a U.S. News & World Report’s “Honor Roll” Hospital, No. 12 in the nation for National Institutes of Health funding, and among the top 10 most innovative research institutions as ranked by the journal Nature in its Nature Innovation Index. This reflects a special level of excellence in education, clinical practice, and research. The Mount Sinai Hospital is ranked No. 14 on U.S. News & World Report’s “Honor Roll” of top U.S. hospitals; it is one of the nation’s top 20 hospitals in Cardiology/Heart Surgery, Diabetes/Endocrinology, Gastroenterology/GI Surgery, Geriatrics, Gynecology, Nephrology, Neurology/Neurosurgery, and Orthopedics in the 2019-2020 “Best Hospitals” issue. Mount Sinai’s Kravis Children’s Hospital also is ranked nationally in five out of ten pediatric specialties by U.S. News & World Report. The New York Eye and Ear Infirmary of Mount Sinai is ranked 12th nationally for Ophthalmology and the South Nassau Communities Hospital is ranked 35th nationally for Urology. Mount Sinai Beth Israel, Mount Sinai St. Luke’s, Mount Sinai West, and South Nassau Communities Hospital are ranked regionally.
