Because Shuanghui Wang Zhongwang is made of pork, and pork is neither cold nor hot, but it belongs to plain food.

Pork is flat and non-cold food, which has the effect of nourishing yin and moistening dryness. Long-term consumption will lead to satiety of the spleen and stomach, weaken the transport function of the spleen and stomach, and lead to moisture condensation. Therefore, people with spleen deficiency and dampness are not recommended to eat pork. Pork is flat and has the effect of tonifying kidney and nourishing blood. Long-term consumption of pork will lead to warm fire, so there are damp-heat symptoms such as dry mouth, bitter taste, diarrhea and dysuria, so it is not recommended for people with damp heat to eat pork. Pork is rich in lipids. Long-term consumption of pork can easily lead to excessive lipid intake, which can not be transported out of the body in time, thus increasing weight and even leading to abnormal lipid metabolism. Therefore, people who were originally obese and hyperlipidemia could not eat pork.
