According to the Daily Materia Medica, ducks can "nourish the yang of the five internal organs, remove fatigue, invigorate qi and promote blood circulation, nourish the stomach and promote fluid production, and relieve cough and asthma."

For those with low fever, weakness, loss of appetite, dry stool and edema, eating duck is the most beneficial.

2. Optimize three meals. Summer meals should be arranged according to the temperature in summer and the physiological changes of the human body. Fruit salad can be one of the ideal breakfast foods. Sweet things such as bananas, figs and cherries are best eaten separately from sour things such as pineapples, oranges and fruits. Don't eat bread with butter, cheese and other fats. The best partner of bread should be salad.
