Walnuts are often discussed as a valuable food for supporting brain function and focus 🌿
The oils in walnuts, especially omega-3 fats, can deteriorate quickly when exposed to light, heat, and oxygen. For this reason, whole walnuts are often preferred over pre-chopped pieces, as their natural shell helps protect these delicate oils.
A simple tip is to include a handful of walnuts with lunch — especially on days that require strong focus or mental effort, such as studying or exams.
