In 2025, there’s a growing emphasis on the connection between diet and overall well-being, particularly concerning gut health. Functional foods—those that offer health benefits beyond basic nutrition—are at the forefront of this movement. These foods play a crucial role in maintaining a balanced gut microbiome, which is essential for digestion, immunity, and even mental health.
🧬 Understanding the Gut-Brain Axis
The gut-brain axis refers to the bidirectional communication between the gut and the brain. Research has shown that the gut microbiome can influence brain function and behavior. For instance, a study by Healthline highlights how gut bacteria affect brain health, suggesting that altering gut bacteria may improve brain health .Healthline+1News-Medical+1
