Essential nutrients that should be prioritized for mental health include omega-3 fatty acids, which support brain function and mood stabilization, found in fish and flaxseed. B vitamins, particularly B12 and folate, play a vital role in producing neurotransmitters that regulate mood. Antioxidants, abundant in berries and green leafy vegetables, help combat oxidative stress, potentially improving cognitive function. Additionally, adequate hydration and a balanced intake of proteins and complex carbohydrates contribute to overall mental well-being, enhancing both energy levels and mood stability.
