Taiwanese and Japanese rice preferences are demonstrated by differences in their cuisine with Taiwan's more flavorful and aggressive cooking methods calling for highly aromatic rice while the Japanese prefer a more subtle and pure taste and smell. During the Japanese Colonial period, Taiwanese cuisine was divided. High-end restaurants, or wine houses, served Chinese cuisine such as Peking duck, shark fin with bird's nest soup, and braised turtle to the colonial elite. In the meantime, those without wealth or connections primarily ate rice, porridge, pickled vegetables, and sweet potato leaves. Cooking oil was considered a luxury and was only used for special occasions. Taiwan's cuisine has also been influenced by its geographic location. Living on a crowded island, the Taiwanese had to look aside from the farmlands for sources of protein. As a result, seafood figures prominently in their cuisine. This seafood encompasses many different things, from large fish such as tuna and grouper, to sardines and even smaller fish such as anchovies. Crustaceans, squid, and cuttlefish are also eaten. Milkfish is the most popular fish in Taiwanese cuisine; it is valued for its versatility as well as its tender meat and economical price. Beef is less common than other proteins, and some Taiwanese (particularly the elderly generation) still refrain from eating it. This stems from traditional reluctance toward slaughtering precious cattle needed for agriculture, and an emotional attachment and feeling of gratitude and thanks to the animals traditionally used for very hard labor. However, due to influences from the influx of mainland Chinese in the 1900s, the Taiwanese version of beef noodle soup is now one of the most popular dishes in Taiwan. American food aid in the decades following WWII which primarily consisted of wheat, beef, and processed meats like Spam forever changed the Taiwanese diet with wheat-based noodles, breads, and dumplings taking a more central role in the cuisine. Rice consumption in Taiwan reached a height of 80-90 kilograms per person per year in the 1960s and 1970s before falling as consumers shifted consumption to wheat-based foods. However, the Taiwanese still consume a large quantity of rice, particularly brown rice and exotic varieties like black, purple, and red rice. Recently rice consumption in Taiwan has enjoyed a renaissance with both growers and consumers devoting the level of care and attention to the rice that is given to high-value crops like tea. Because of the island's sub-tropical location, Taiwan
