Nuts are a type of plant fruit, usually referring to dried fruits with hard skin that do not crack when ripe. They are rich in protein, unsaturated fatty acids, and various minerals, and are an important plant-based food resource for humans. According to different sources, nuts are mainly divided into two categories: woody nuts (such as walnuts and cashews) and herbal seed nuts (such as peanuts and sunflower seeds). Moderate consumption can help with cardiovascular health and metabolic regulation.
