Modern urbanites often work overtime due to busy schedules, and coupled with the common traffic congestion in big cities, they often get home after dark, with many even not having dinner until 8 or 9 PM. The next day, because they have 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 ample 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 dawn. Therefore, it is more appropriate to have breakfast around 7:30; additionally, a 4-5 hour interval between breakfast and lunch is ideal, which also suggests that eating breakfast between 7:00 and 8:00 is best.
Many office workers, for convenience, will cook extra food for dinner and reheat it the next day. This is not advisable, as leftover food can produce nitrites, which are harmful to human health. Also, office workers often eat Western-style fast food like hamburgers and fried chicken wings, 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 on the street and eating while walking, which is detrimental to gastrointestinal health and不利于 digestion and absorption.
Experts suggest that a healthy breakfast should include these elements: whole grains to enhance satiety and allow for slower blood sugar release; animal foods like meat and eggs to supplement protein, providing energy that is released continuously for several hours; and vegetables, with fruit eaten 1 hour after the meal, to provide the body with dietary fiber, vitamins, and minerals.
