5 Foods That Are Making Your Brain Fog Worse

Brain fog isn’t just a normal part of getting older—and it may not be a brain problem at all. If you struggle to focus, lose your train of thought, forget why you walked into a room, or feel mentally exhausted after eating, your body may be trying to tell you something.

Here’s what I discuss in today’s episode:

• The five foods I most commonly see contributing to brain fog—and why some seemingly “healthy” choices may be working against you

• The surprising connection between your gut and your ability to think, focus, and remember

• Why certain foods can affect your brain even when you don’t have obvious digestive symptoms

Brain fog is a messenger, not the root problem. When you start looking at what’s happening throughout your body—especially your gut, blood sugar, inflammation, and microbiome—you can begin uncovering what’s getting in the way of a clearer, healthier brain.
