Healthy snacks are typically defined by their nutritional value, offering essential nutrients while being lower in added sugars and unhealthy fats. Examples include fresh fruits, vegetables with hummus, or unsalted nuts. In contrast, unhealthy snacks often contain high levels of processed sugars and trans fats, providing empty calories with little nutritional benefit. Healthy snacks promote sustained energy levels and may aid in weight management, while unhealthy options can lead to energy crashes and poor dietary habits. Making informed snack choices is vital for maintaining overall health and wellness.
