Abstract

Sustainable diets are defined as those that present low impacts both on the environment and the biodiversity, contributing to food and nutrition security and to a healthy life for present and future generations. Algae (macroalgae and microalgae, including cyanobacteria) have recently taken an increased interest as valuable products, being used as ingredients or condiments in the modern diversifying occidental cuisine. Moreover, nutritional research has confirmed algae as rich sources of potentially valuable, health-promoting compounds in a scenario where consumers are increasingly aware of the relationship between diet, health and disease prevention. Combining both ideas, nutritional needs vs. health promotion and disease risk reduction, algae are shown as a very interesting source of functional ingredients for being considered as a component of our day-to-day diet and related food products. Sustainability contribution of cultivation systems and techniques to biomass increasing in quality, security and control, so reducing effects on the environment and biodiversity, makes algae production a promising activity to be included in future developments toward a responsible and healthy way of living.
