Which statement about nutrition and mood is most accurate?

• A. Regular meals have no effect on mood
• B. Consuming omega-3 fatty acids alone cures mood disorders
• C. Deficiencies (e.g., omega-3, B vitamins) can affect mood
• D. Nutrition cannot influence neurotransmitter synthesis

Answer: (C)

Nutrition status influences mood because the brain relies on specific nutrients to function and to produce mood-regulating chemicals. When someone is deficient in nutrients such as omega-3 fatty acids or B vitamins, mood can be affected through multiple pathways. Omega-3s support neuronal membranes and help regulate inflammation in the brain; low levels have been linked to depressive symptoms and mood disturbances. B vitamins—like B12, folate, and B6—act as cofactors in the production of neurotransmitters such as serotonin, dopamine, and norepinephrine, and are involved in energy metabolism; deficiencies can contribute to mood changes and irritability. These connections show why maintaining adequate nutrition is important for mood.

Regular meals matter because stable energy and blood glucose help maintain steady mood; skipping meals can lead to irritability and fluctuations in mood. While omega-3s and other nutrients can support mood, they are not cures for mood disorders and work best as part of a broader treatment plan. Conversely, nutrients do influence neurotransmitter synthesis by providing precursors and cofactors, so the statement that nutrition cannot affect neurotransmitter synthesis isn’t accurate.
