Experts have raised concerns over the impact of afternoon snacking habits on brain health, particularly highlighting the risks associated with sugary and ultra-processed snacks. They indicate that many Americans make unwise eating choices between lunch and dinner, which could potentially have lasting effects on how the body and brain manage blood sugar levels throughout the day. This seemingly simple act of snacking could be far more complex, affecting energy levels and cognitive function.

Kiara DeWitt, a certified neurology nurse, emphasizes that blood sugar fluctuations can be particularly harmful for brain health because the brain does not have a reserve of glucose to draw upon. Consuming simple sugars can cause rapid spikes in blood sugar, which are often followed by crashes, contributing to cognitive issues over time. Experts suggest that the consumption of snacks high in sugar and inflammatory oils can exacerbate these fluctuations, leading to negative consequences for brain health.

This advice comes amidst a growing body of research linking ultra-processed food consumption to rising levels of chronic disease, including cognitive decline and dementia. It serves as a call to action for individuals to be more mindful of their snack choices in the afternoon to promote better brain health and manage blood sugar levels effectively.
