Up till now we’ve had macronutrients (carbohydrates, lipids, proteins) that provide energy and structure to nourish our bodies and help us grow; and micronutrients (vitamins, minerals) that enable it to function. Mesonutrients are the healthy "maintenance" molecules that can help prevent disease, and even heal. For example: omega-3s (from salmon), curcumin (from curcuma), gingerols (from ginger), anthocyanins (from blueberries), etc.
