Cereals and pulses make important contributions to carbohydrate and protein intakes. Data collected by the International Food Information Council (IFIC) show consumers reported eating fewer carbohydrates during the last decade, yet consumers consistently rank fiber and whole grains as two of the most healthful foods or nutrients to eat. IFIC data also show more favorable opinions among consumers about plant sources of protein compared with animal sources, but there is a recognition that both protein sources can be included in eating patterns that are healthy and environmentally sustainable. In addition, Americans are choosing a variety of eating styles for reasons that include personal and planetary health. Environmentally sustainable foods are viewed by many consumers as beneficial to human health, and with concerns about climate change growing, there is interest in more environmentally friendly food options. However, it is difficult for consumers to know whether a food choice is environmentally sustainable. Therefore, understanding the evolving food perceptions and values of the American consumer, particularly with regard to plant foods, is vital to communicating credible information about the impact of food choices on personal and planetary health.
