ELI5: Explain Like I'm 5

Russell Blaylock

Russell Blaylock is a doctor who studies how the brain and body work together. He tries to figure out how things we eat or things we're exposed to can affect our health. He thinks some things, like chemicals in food or pollution in the air, can be harmful to our brains and bodies.

Dr. Blaylock studies things called "neurotoxins." These are chemicals that can harm the cells in our brains and make us sick. He thinks that certain foods or medicines can contain these neurotoxins and that they can harm us over time.

Dr. Blaylock also studies something called "excitotoxins." These are chemicals in our brain that can become overactive and cause damage to cells. He thinks that certain foods and additives can make these excitotoxins overactive and cause problems.

Dr. Blaylock believes that eating a healthy diet, avoiding chemicals and additives, and getting enough exercise can help keep your brain and body healthy.
