A recent study by nutritionists shows that foreign fast food, especially McDonald's food, is a serious health hazard for children. Some experts even pointed out that a fried chicken leg is equivalent to the toxins of 60 cigarettes, which not only causes nutritional imbalance in the body, but also has serious damage to the development of children's brains.

Some chicken farms add large amounts of hormones to chicken feed in order to accelerate growth and development, which increases the risk of precocious puberty in children who love to eat fried chicken legs. This study is a wake-up call for McDonald's-loving teens.
