Diet and Mental Health: Can What You Eat Affect How You Feel?
Research shows a strong connection between your gut and brain, which plays a major role in how you feel. Eating certain foods and adopting healthy dietary habits can help improve your mood and overall mental health.
Diet and Mental Health:
Is There a Link?
Mental health conditions have traditionally been treated with psychiatric therapies like counseling, medication, and sometimes hospitalization.
Today, an emerging field called nutritional psychiatry emphasizes how diet and nutrition affect mental health. It aims to support the treatment of mental health conditions with dietary and lifestyle changes.
Your food choices may affect your brain through the gastrointestinal system—commonly referred to as the gut—because it is closely connected to the brain.
The Gut-Brain Connection
The gut is home to trillions of living microbes that play essential roles in the body, such as synthesizing neurotransmitters that send chemical messages to the brain to regulate sleep, pain, appetite, mood, and emotion. There is such a complex network of interactions between the gut and brain that scientists have nicknamed the gut the “second brain.” Formally, this relationship is called the gut-brain axis.Some research suggests that the foods we eat influence the health of gut microbe colonies, which subsequently affect our brain and, thus, our mental and emotional health.
