The Paleo diet is based on consuming foods eaten by early humans, such as meat, fish, vegetables, and fruit, and excluding dairy or grain products and processed food. Researchers asked eight healthy people who usually consumed a diet high in processed foods to switch to the Paleo diet for eight weeks. During the study, the researchers found that participants experienced a 35% increase in levels of interlukin-10 (IL-10), a signaling molecule secreted by immune cells. Scientists believe that higher IL-10 levels may protect blood vessels and lower one’s risk for a heart attack.
