Eating a whole rotisserie chicken can be beneficial to one's health, however, it can also be unhealthy depending on the ingredients. Eating a lot of processed food can lead to an unhealthy diet. Rotisserie chickens can be high in sodium, fat and calories, so eating too much of it can be bad for your health. To make it healthier, choose a rotisserie chicken with little or no added ingredients, such as preservatives and artificial flavors. Also, avoid eating the skin of the chicken, as it is high in fat. Lastly, consider eating rotisserie chicken in moderation and supplementing it with a balanced diet of fresh fruits and vegetables.
