Nutrition is not only about calories and food quality — meal timing also plays an important role in health. Chronobiology, the science that studies the body’s internal clock, shows that metabolism, digestion, hormones, and energy levels change throughout the day.

Mental health is influenced by many factors, including sleep, stress, physical activity, and nutrition. Research increasingly shows that dietary patterns can affect mood, energy, focus, stress response, and cognitive function through inflammation, gut health, blood sugar regulation, and neurotransmitter production.

Nutrition alone does not treat ADHD, but growing research suggests that eating habits may influence attention, energy levels, mood, and cognitive performance. Certain nutrients support brain function and neurotransmitter production, while highly processed foods and excess sugar may negatively affect focus and behavior in some individuals.
