What are the solar terms in cooking (chef)? And the relationship between honesty and diet?

Solar terms refer to the 24 solar terms and climate, which is a supplementary calendar invented by China in ancient times to guide farming. Because the lunar calendar in China is a kind of "yin and yang calendar", which is based on the movement of the sun and the moon, it can't fully reflect the solar cycle. But China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is entirely based on the sun. Therefore, the "twenty-four solar terms" that reflect the solar cycle alone are added to the calendar as the standard for determining leap months. China's orthodox twenty-four solar terms are based on Henan.

origin

In ancient China, the sundial was measured by earth gauge, and the longest sun shadow was defined as "sun to day" (also called long day to day, long day to day, winter to day), and the shortest sun shadow was "short day to day" (also called short day to day and summer to day). One day in spring and autumn is the same length of day and night, which is designated as "vernal equinox" and "autumnal equinox". There were only four solar terms in Shang dynasty, but it developed to eight in Zhou dynasty and was completely established in Qin and Han dynasties. In BC 104, the taichu calendar written by Deng Ping officially set 24 solar terms in the calendar, and defined the astronomical position of the 24 solar terms.

The names of the twenty-four solar terms first appeared in Tian Zi Xun of Huainan, and the concepts of Yin and Yang, four seasons, eight places, twelve degrees and twenty-four solar terms were also mentioned in Preface of Historical Records Taishi Gong. During the period of Emperor Wu of the Han Dynasty, Luo compiled solar terms into the calendar, stipulating that the month without neutral gas was the last month of leap month.

Each of the 24 solar terms corresponds to a certain position reached by the sun every time it moves 15 on the ecliptic. The twenty-four solar terms are divided into 12 solar terms and 12 solar terms, which correspond to each other one by one. The twenty-four solar terms reflect the annual apparent motion of the sun, so their dates are relatively fixed in the Gregorian calendar. The solar terms in the first half of the year are on the 6th, the solar terms in the second half of the year are on the 8th and the solar terms are on the 23rd, with a difference of less than 1 ~ 2 days.

The naming of the twenty-four solar terms reflects three seasons, climate phenomena and climate change. The reaction seasons are beginning of spring, Spring Equinox, Long Summer, Summer Solstice, beginning of autumn, Autumn Equinox, beginning of winter and Winter Solstice, also known as Eight; The response to climate phenomena is surprised, bright, full and mans; Rain, Grain Rain, little summer, big summer, early summer, white dew, cold dew, first frost, light snow, heavy snow, slight cold and severe cold are the responses to climate change. Key points of spring solar terms diet: choose light and bitter fresh ingredients to slow down the soil.

Spring is the beginning of vitality and the season of "moving", which consumes the earth's force-the heat stored by the body in winter. Otherwise, soil-borne diseases may occur, such as colds, stuffy noses, trachea and lung problems.

Therefore, the focus of spring diet is to slow down soil strength and eat more dark green vegetables, which are slightly bitter, slightly pungent, dry and light. Ginger can warm the body and strengthen the fire of digestion.

Pay attention to the sunrise time every day, go to bed early and get up early, and don't sleep too much; And exercise regularly, keep clean, eat fresh and simple food, and make a good start for your health.

Key points of summer solar term diet: to avoid the deterioration of fire type and light diet, there must be "ups and downs" to balance.

Summer is easy to get angry and easy to digest, and high temperature will weaken digestion. Fire type has the taste of "sour, salty and spicy", and fire type people especially like to eat sour, salty and spicy dishes. So there must be "ups and downs" to balance. You can choose sweet, cool and moist foods, such as porridge, coix seed meat, mung bean soup, sweet fruit, tofu and lemon to balance the fire type. Aloe juice is cold and good for the liver.

In summer, maladjustment symptoms are: mosquito bite, rash, sunburn, allergy, digestive organ ulcer or liver disease. Learn to add coolness to life, such as walking in the moonlight on a summer night.

When the rainy season comes, people of any size are prone to problems. The cold, sour and wet rain is not good for wind, fire and soil types.

Honey is warm and dry, which can balance moisture, but it will not worsen the fire type. You can eat more whole grains, such as buckwheat, barley, rice, wheat, oats, etc., or you can add them to hot soup containing a variety of vegetables and cook them together, and add a proper amount of oil. Weak physical strength and digestive ability can be added with sour and sweet taste.

Key points of autumn solar terms diet: No matter what body type, you need warm, moist and oily food in autumn.

Autumn belongs to the wind type. If the wind-type person loses his balance in autumn, his skin will be very dry, his joints will be sore, he will creak, he will be prone to flatulence, and there will be nervous system disorders, such as neuralgia, low back pain, arthritis and insomnia. Circulatory diseases, such as heart disease, hypertension and arteriosclerosis, may also occur; Easily nervous and worried. Also pay attention to constipation. Earth-type and fire-type people breathed a sigh of relief after autumn, without the heat and humidity of summer.

Taste emphasizes sweetness, sourness and saltiness. Wind-type people especially need whole grains, such as rice and wheat products, glutinous rice, soup, thick soup, root vegetables, beans and so on to balance.

Main points of winter solar terms diet: hot whole grains, especially rice, oats, whole wheat noodles and so on.

Winter belongs to the natives, so we should pay attention to the balance of the three forces in winter in order to keep healthy. Soil strength promotes growth and enhances immunity and memory; Earthwork lubricates joints, connects tissues and organs, moistens skin and digestive tract, and activates cardiopulmonary function.

Wind type palm damage, fire type main maintenance, soil type pipe construction. The middle and late winter is a good time to build a healthy body and mind, so it makes sense to emphasize winter tonic.

In winter, the diet is mainly hot grains, with more beans and moderate spicy taste, hot soup, hot tea, hot milk and honey.

Summer and autumn are a great test for fire-type people; Autumn and winter are a big test for people with wind style; Late winter and early spring are a big test for local people; The rainy season is a joint exam.

Fire-type people have a bad summer, and their inflammation and allergies are small warnings;

Wind-type people have a bad summer, and there will be problems with their skin, bones and digestion.

If the indigenous people have a bad winter, their heart and lung organs will be in danger.
