Oxidative stress occurs because of an imbalance in the production of reactive oxygen species. Nuts are rich in bioactive compounds, including phenolic compounds, tannins, and phytosterols. Although nuts are widely consumed because of their beneficial effects on nutrition and health, there is limited information about bioactive peptides from nuts. Pine nut and walnut-derived peptides are the most studied because these nuts contain a higher amount of protein. Different biological activities have been demonstrated for nut peptides; many of them exhibit antioxidant, anticancer, antihypertensive, antidiabetic, immunomodulatory, antiseizure, or neuroprotective activity. Recent studies have focused on increasing the bioactivity of identified bioactive peptides by applying new technologies and chemosynthetic strategies. Research tendency points to the generation of peptides with specific sequences for application in specific diseases. Nut bioactive peptides can become key functional ingredients for food, pharmaceuticals, or cosmetics. © 2022 Institute of Food Science and Technology.
