Some gut microbes help the body absorb more dietary fat, which means their host takes in more calories from the same amount of food.
“This study is the first to demonstrate that microbes can promote the absorption of dietary fats in the intestine and their subsequent metabolism in the body,” says senior study author John Rawls, associate professor in the department of cell and molecular physiology at University of North Carolina School of Medicine.
“The results underscore the complex relationship between microbes, diet, and host physiology.”
It may be great for curing a splitting headache, but scientists have now discovered that aspirin also activates an enzyme that burns fat, a finding that could unlock its cancer fighting properties, according to a new study. Previous research has shown that once ingested, aspirin breaks down into salicylate, a compound derived from plants such as willow bark, and used as a drug for thousands of years. Ancient Egyptians recorded the medicinal use of willow bark in their manuscripts. In the 1890s, pharmaceutics developed a modified form of salicylate to make it less irritating to the stomach - creating the drug aspirin. More recently, research has known that salicylate triggers a molecular pathway that leads to pain relief. Now a team led by Professor Grahame Hardie, a cell biologist at the University of Dundee in Scotland, has discovered how salicylate affects metabolism. They report their findings today in the journal Science. Hardie and his team suspected that salicylate affected an enzyme known as AMPK, which is a key regulator of cell metabolism.
