Optimizing cognitive function requires a constant supply of neurotransmitter precursors. Eggs are the richest source of choline, a nutrient essential for the synthesis of acetylcholine, a neurotransmitter responsible for memory, concentration, and muscle control. Adequate choline levels support the structural integrity of neuronal membranes and facilitate rapid communication between synapses. Eating two eggs for breakfast provides almost 100% of the recommended daily intake of choline for an adult. To preserve the quality of nutrients, choose soft-boiled or poached eggs, avoiding excessive frying, which can oxidize the healthy cholesterol contained in the yolk.
