The vikings are looking forward to it, the fourth of july and mid-autumn, finally
However, mid-autumn is a traditional chinese holiday, and besides the girls, it is necessary to leave relatives to give gifts。
Mid-autumn gifts love tea, but it's too much sorted and talked about, and it's just a stupor...
So, today, the vittorios will tell you in the middle of the autumn
1. Basic knowledge of tea
2. How to select suitable tea。
So you don't have to worry about the mid-autumn gift or the routine
What is the composition of the tea and its efficacy
In fact, tea can be a popular option for mid-autumn gifts and even daily gifts, not only because of custom, but also because it serves as a national drink in china and has a great health function。
They include beauty, loss of weight, slowing old age, etc., which, thanks to the many health components of tea leaves, are described below。
The composition of tea can be divided into "nutrients" and "non-nutrients"。
Nutritional components, mainly proteins, fats, carbohydrates, multiple vitamins and minerals, are also nutrients in general。
Non-nutrient components (not basic nutrients required for humans but with health effects), including tea polyphenols, pigments, tea amino acids, bioalkalis, aromatics, etc。
Among them, the non-nutrient components that function as health care are mainly three categories:
1 tea polyphenol
It includes tea, ketone and phenol。
Tea polyphenol is highly resistant to oxidation
2. Tea amino acid
Tea amino acid is an important component in the formation of tea aroma and fresh coolness, which has the effect of reducing pressure and promoting brain function。
3. Bioalkali
Includes caffeine, cacao-alkali, tea-alkali. It's got the power of agitation。
You see how hot tea is to the human body. Don't think tea is a gift for the elderly, just turn it off。
What are the main categories of tea
In fact, in terms of tea production, tea is divided into two main categories: fermented tea and unfermented tea。
However, because of the different levels of fermentation, which lead to different colours of tea bubbles and can be divided into many different types, vitamins are a small housekeeper of family nutrition with a combination of talent and humor
You may have to ask again what fermentation means. Vital dogs explain the difference between non-fermented tea and fermented tea in terms of its efficacy
• no fermented tea: more natural substances in tea are retained, which have anti-inflammation, fungi, anti-age effects, but are somewhat irritating to the stomach compared to unfermented tea。
• fermented tea: the tea is milder, is not very irritant to the gastrointestinal stomach and has a three-tier effect of stomach rearing and regulation; however, there is a corresponding loss of antioxidation。
The names are the name of the market goods. The unknown do not know whether the point is green tea or yellow tea, so the vitamins match them to the type of tea
Vitamins advise you to save this picture and buy tea in the future。
After all, your little brains have all these things, and there's no need to burden them。
How to choose a suitable tea
With regard to selection, apart from personal preferences, we should start with nutrition and effectiveness。
After all, the health effects of tea cannot be wasted, and it can hurt your body if you drink it wrong。
I'm afraid you'll get dizzy when you look at the text
However, there are others who are not at all fit for tea, and it would be bad to have a gift if they met the following categories。
1. Insomnia population
The caffeine contained in the tea stimulates the central nervous system, which makes it impossible to sleep。
2. Patients with stomach ulcer
Café base in tea promotes stomach acidization and increases stomach acid concentrations, which in turn exacerbates stomach ulcer conditions。
3. Groups suffering from malnutrition (especially iron deficiency anaemia)
Tea contains tea alkalis and acrylic acids that affect human absorption of nutrients such as iron and protein。
4. Pregnant women
The caffeine contained in tea increases the amount of urine, heart beats, frequency of pregnant women and increases their heart and kidney load。
5. Calcium deficiency/breeding patients
The biobasin contained in tea inhibits the absorption of calcium by the 12-finger intestine, and prolonged administration leads to calcium deficiency, osteoporosis and fractures that are difficult to recover。
6. Fever patients
The bioalkalis contained in teas increase human temperature and reduce the temperature of drugs。
7. Customary constipation
The tea contains tea polyphenol which is distilled from the gastrointestinal mucous membranes and which increases constipation。
What do you care about tea
I'm sure we all know the basics of tea, but there are a few more things that i want to tell you:
1. No empty stomachs for tea
The empty abdominal consumption of tea dilutes the stomach fluid, reduces the function of gastric acid, hinders digestion and affects protein absorption, and is prone to stomach mucus。
2. Less tea
Heavy tea contains caffeine, with a high level of alkaline, is highly irritating and prone to headaches and insomnia。
Tea water can generally remain in the human body for about three hours, while strong tea can remain for longer periods, resulting in excessive accumulation of tea alkaline in the human body, which can cause nervous disorders。
Also, as a result of acid stinging in tea leaves, the intestinal mucous glucose function is reduced and constipation occurs。
So, vitamins usually recommend 5-10 grams of tea per day, which is good for two。
3. Don't rush too long
For too long, tea polyphenol in tea leaves, aromatic substances (fragrance composition) etc. Can be oxidized and volatile。
No tea before bedtime
It would be preferable not to drink tea two hours before bedtime, otherwise it would cause over-healing and even insomnia。
Older persons drink tea before they go to sleep, they are also prone to panic and urination, which affects their sleep。
There's a lot of work going on today, and seeing you here must be a very serious man
However, today's vitamins are too lazy to sum up, because the dry stuff is in the chart in the article. You move your fingers and save them
