Eating chicken breast is usually not harmful, but it needs to be eaten in moderation. Chicken breast is high in protein, which is easily digested and absorbed by the human body. And less fat content, delicious flavor, moderate consumption can supplement the body’s protein and a variety of nutrients. Every 100g of chicken breast contains about 125 calories, and its protein content can reach 27/100g, which is higher than beef, pork, eggs and other foods. Although chicken breast is easy to be digested by the human body, but long-term consumption of large quantities will lead to excessive protein intake, and aggravate the burden on the gastrointestinal tract, resulting in slow digestion, easy to cause bloating, indigestion and so on. Because protein will be metabolized by the liver and kidneys after entering the body, long-term large intake of chicken breast and other protein foods will increase the burden on the liver and kidneys. We should pay attention to the balance of nutritional intake, avoid long-term, excessive intake of chicken breast, pay attention to other nutritional elements, such as fresh fruits and vegetables, grains and cereals.
