Description

There’s been a surge in our consumption of ultra-processed foods, especially in the United Kingdom and the United States, where these foods contribute about two-thirds of people’s caloric intake.

Also a cause for concern is emerging evidence of ultra-processed foods’ detrimental effect on our brain health and overall well-being.

When most of our calories come from ultra-processed foods, the risk of chronic physical and mental health conditions escalates. Scientists are now uncovering the intricate mechanisms behind this relationship, particularly concerning the effects of these foods on our brains.

In today’s episode, we welcome back Prof. Felice Jacka, OAM. Felice is an Alfred Deakin professor of nutritional psychiatry and the director of the Food & Mood Centre at Deakin University, in Australia. She’s also the founder of the International Society for Nutritional Psychiatry Research and the world’s leading researcher on food’s impact on our brain and mental health.

Now, she’s back on the show to delve deeper into the effects of ultra-processed foods on mental health and the brain, specifically the hippocampus, an area responsible for learning and memory.
