The best time for breakfast is from 7 to 8. When people sleep, most organs get a full rest, while the digestive organs are still digesting and absorbing the food left in the gastrointestinal tract at dinner, and gradually enter a state of rest in the morning. Get up around 7 o'clock and have breakfast after 20 ~ 30 minutes. At this time, people's appetite is the most vigorous. The interval between breakfast and lunch is about 4-5 hours.

Breakfast (breakfast/breakfast), also called breakfast, refers to a meal enjoyed in the morning. It is usually concentrated from six to eight in the morning. Breakfast food is different all over the world, and cereal is usually the main food. European and American breakfasts are divided into continental breakfasts, English and Irish breakfasts and American breakfasts according to food content. This concept comes from Britain, which is what the British refer to as continental breakfast in English context. But in fact, there are many kinds of breakfasts in European countries, so the concept of continental breakfast cannot cover all breakfasts in continental Europe.

The definition of "continental breakfast" has gradually evolved into "simple breakfast" over time. Therefore, in the western restaurant of a star-rated hotel, the concept of "continental breakfast" in the menu refers to a simple breakfast that only provides coffee, tea, milk, butter, jam, bread and juice. This breakfast does not serve cereals, meat, sausages and eggs. In star-rated hotels, American breakfast is defined as "composite breakfast" and "full breakfast". English and Irish breakfasts are only popular in England, Ireland and Wales because they have special food contents.
