Your brain is nearly 60% fat, with omega-3s being among the most important components. DHA, a key omega-3 fatty acid, makes up about 30% of your brain's fat content and is essential for cell communication, memory, and mood regulation. While fish has traditionally been recommended as a source, plant-based options like flaxseeds, walnuts, and algae offer these brain-boosting benefits without the environmental concerns and potential contaminants. Even small daily additions of these foods can support your mental wellness throughout life.
