Some experts say your daily sandwich could be affecting your mood. That’s because gluten, a protein in bread, may cause inflammation in the gut for some people. This can impact brain health and lead to symptoms like anxiety, fatigue, or brain fog — especially in people who are sensitive to gluten.

The gut and brain are closely connected. When the gut isn’t healthy, it can affect how you feel mentally. Highly processed breads with added sugars and chemicals are more likely to cause problems. But not all bread is bad. Whole wheat and gluten-free options made with ingredients like quinoa or millet can be better choices.

Experts say the focus shouldn’t be only on what to avoid. It’s also important to eat foods rich in nutrients that support mental health, like omega-3 fats, B vitamins, and fiber. A balanced diet with whole foods can help your brain and body feel their best.
