Due to busy work and frequent overtime, combined with common traffic congestion in big cities, urban dwellers often return home after dark, with many not having dinner until 8 or 9 PM. The next day, because they need to get up early, breakfast is naturally eaten very early. Medical experts point out that because dinner is eaten too late, while most organs get sufficient rest during sleep, the digestive organs are still digesting and absorbing food left in the gastrointestinal tract from dinner, only gradually entering a resting state around 4 AM. Therefore, it is more appropriate to eat breakfast around 7:30; furthermore, a 4-5 hour interval between breakfast and lunch is also ideal, which suggests that eating breakfast between 7:00 AM and 8:00 AM is best.
Many office workers, for the sake of convenience, cook extra food for dinner and reheat it the next day. This is not advisable, as overnight dishes can produce nitrites, which are harmful to human health. Also, office workers often enjoy Western fast food like hamburgers and fried chicken wings for breakfast, but this type of breakfast is too high in calories and can easily lead to obesity. Another common habit among office workers is buying breakfast from roadside stalls and eating while walking, which is detrimental to gastrointestinal health and不利于 digestion and absorption.
Experts recommend that a healthy breakfast should include the following elements: whole grains to enhance satiety and allow for a slower release of blood sugar; animal foods like meat and eggs to supplement protein, providing sustained energy for several hours; and vegetables, with fruit consumed one hour after the meal to provide the body with dietary fiber, vitamins, and minerals.
