Diet and culture
China is a vast and diverse country and styles and tastes of Chinese cuisine vary by class, region, and ethnic background. Traditionally, Chinese cuisines were more plant-based with various vegetables and soy products, and stir-frying, the most common method to cooking vegetables became a way to conserve original flavor of foods by cooking food quickly. Historically, most people, especially members of the upper class, preferred food prepared in smaller pieces, readily picked up and eaten with chopsticks. Meat was typically cut into smaller pieces and then mixed with other ingredients like vegetables or noodles; while larger pieces like whole chicken or ham were used in stews. Rice remains a major staple food, particularly for those living in southern China. The Chinese word for rice is “fan” which also means “meal.” Rice may be served with any meal, and is consumed 2-3 times a day. Modern staple foods include white rice, noodles (made with rice or wheat flour), corn, potato, a variety of vegetables including bok choy, green beans, Chinese spinach, Chinese broccoli and watercress as well as soy products like tofu and soy milk.
