Food doesn’t last. In days, sometimes hours, bread goes moldy, apple slices turn brown, and bacteria multiply in mayonnaise. But you can find all of these foods out on the shelf at the grocery store — hopefully unspoiled — thanks to preservatives. But what exactly are preservatives? How do they help keep food edible? And are they safe? Eleanor Nelsen investigates.

What is MSG, and is it actually bad for you? – Sarah E. Tracy

What is MSG, and is it actually bad for you? – Sarah E. Tracy

Dig into the seasoning known as MSG, and find out how this flavoring was developed and if it’s actually bad for your health.

—

In 1968, Dr. Robert Ho Man Kwok felt ill after dinner at a Chinese restaurant and wrote a letter to a medical journal connecting his symptoms to MSG. His letter would change the world’s relationship with MSG, inspiring international panic, biased science, and sensationalist journalism for the next 40 years. So what is this seasoning, and is it actually bad for you? Sarah E. Tracy investigates.
