DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Could the keto diet help prevent or mitigate severe COVID-19?

A new study published in the journal of Translational Medicine reports that the ketogenic diet (KD) may be useful in this area, with its track history of effectual reduction of fat mass, anti-inflammatory and immunomodulatory effects, and consequent improvement of cardiovascular health.

Regulation of fat production is abnormal in obesity, shows study

Gut hormones play an important role in regulating fat production in the body. One key hormone, released a few hours after eating, turns off fat production by regulating gene expression in the liver, but this regulation is abnormal in obesity, researchers at the University of Illinois Urbana-Champaign found in a new study.
