Italian hazelnuts, commonly referred to as walnuts, represent the fruit of trees belonging to the walnut family (*Juglandaceae*). Distinguished by their exceptional chemical composition, they are abundant in B-complex vitamins, essential trace and macro minerals (including magnesium, phosphorus, and potassium), and valuable fatty acids—primarily monounsaturated and polyunsaturated—which play a pivotal role in maintaining the body’s lipid homeostasis. Owing to their high nutrient density and balanced ratio of energy-yielding components, they serve as an indispensable source of sustained energy, facilitating both metabolic processes and neurocognitive functions.
