1. Combine spinach and kale in a bowl.
2. Whisk olive oil, lemon juice, salt, and pepper. Drizzle over greens and toss.

5. Whole Grains

Whole grains, such as oats, quinoa, brown rice, and whole-grain bread, provide a steady supply of glucose to the brain. Glucose is the primary energy source for the brain, and maintaining stable blood sugar levels is essential for focus and concentration. Whole grains are also rich in B vitamins, which play a crucial role in brain health by reducing inflammation and supporting neurotransmitter function. This helps improve memory and cognitive abilities.

How to incorporate: Start your day with a bowl of oatmeal, prepare quinoa-based salads, or use whole-grain bread for sandwiches. Opt for whole-grain options whenever possible.

Recipe: Quinoa and Vegetable Stir-Fry

• 1 tbsp sesame oil

1. Heat sesame oil in a pan. Add vegetables and stir-fry until tender.
2. Stir in quinoa and soy sauce. Cook for 2 minutes. Serve warm.

6. Eggs

Eggs are an excellent source of several brain-boosting nutrients, including choline, vitamin B12, and folate. Choline is essential for the production of acetylcholine, a neurotransmitter involved in memory and learning.

Vitamin B12 supports the health of nerve cells and helps prevent brain shrinkage, a condition associated with cognitive decline. Folate complements these functions by promoting the production of neurotransmitters and maintaining overall brain health.

How to incorporate: Enjoy eggs as part of your breakfast, whether boiled, scrambled, or in an omelet with added vegetables. They can also be a versatile ingredient in salads or as a protein-rich snack.
