Coffee knowledge, after all, coffee causes cancer or prevents cancer?

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

For a reason, it starts with the institution called IARC, which is called International Agency for Research on Cancer in English and International Agency for Research on Cancer in Chinese. After classifying processed meat products such as ham as Class 1 carcinogens and red meat as Class 2A carcinogens, coffee has been moved from Class 2B carcinogens to Class 3 carcinogens.

In other words, they used to think that coffee "may cause cancer." now they think that coffee "has no conclusive evidence to prove that it causes cancer." more formally, it is described as "insufficient evidence of carcinogenicity in humans and insufficient or limited evidence of carcinogenesis in laboratory animals."

This actually means that IARC has not found evidence that "drinking coffee causes cancer", or even "limited evidence".

Reversal of the evidence revealed

A recent meta-analysis of 59 studies shows that drinking coffee actually "reduces the overall incidence of cancer, and it is also negatively associated with certain types of cancer."

In 2015, another scientific review concluded that "according to current scientific advances, coffee drinking has nothing to do with most cancers, although scientific findings on bladder and lung cancer are still controversial, but in cases of bowel, liver and breast cancer, drinking coffee may even have a protective effect."

In April 2015, a study published in Cancer Epidemiology, Biomarkers and Prevention showed that coffee reduced the risk of colorectal cancer in a dose-dependent manner.

A good drink with a low profile

We all know that drinking coffee before going to bed will affect sleep and health, but when you drink coffee moderately when you work and study, you can get a sober and efficient brain state.

Coffee actually has many low-key advantages: for example, it can reduce the risk of diabetes (type 2), high blood pressure and depression, and may be slightly beneficial in helping to prevent coronary heart disease, congestive heart failure, arrhythmia and stroke. There is also some evidence that drinking coffee reduces the risk of cognitive decline and Parkinson's disease and improves asthma.

No matter how good it is, you have to drink it properly.

According to the first rule of the golden rule, "everything has its limits", even the best coffee should be drunk to a certain degree.

Given the results of most studies, drinking 2-3 cups (about 240 milliliters) of coffee a day is safe and beneficial.

In response, the American College of Obstetricians and Gynecologists in 2015 reiterated their position that consuming 200 milligrams of caffeine a day does not pose an adverse risk to pregnancy. Generally speaking, 200 mg is equivalent to the amount of caffeine in about 340 grams of coffee (caffeine content varies with different preparation methods).

The necessary work for the location of a coffee shop

When choosing a suitable store address, we must consider whether the area is a place where consumers are concentrated and have certain functions, such as economic, political, cultural, commercial and other functional centers or transportation hubs. After the address is selected, we should always pay attention to the changes in the surrounding environment. Generally speaking, most of them take the coffee shop as the center and draw a radius of 1 km or 1.5 km as the business circle of the coffee shop. However, when setting up the coffee shop business area, we should pay attention to: generally, the beverage business area is smaller, while the ground coffee business area is larger. In addition, the traffic situation and the facilities in the area may affect the distribution of the business area. For example, in coffee shops near the railway, the division of the business circle may be defined by the railway, and the coffee shops on both sides of the river may also be bounded by the river. Because of these artificial or natural differences, it will often cause differences in the consumer psychology of customers.

Of course, coffee shop operators must also understand what kind of area our customers are in, and conduct an in-depth survey of the population, customer level, occupation profile and consumption characteristics of this area, in order to grasp the consumption habits of consumers in this area.

Usually, in order to effectively grasp the characteristics and distribution areas of customers who come to the store, coffee shop operators should often collect the opinions of customers who come to the store and give them some concessions or gifts. Ask them to leave basic information (name, age, sex, occupation, address, etc.). The distribution of customers in the store can be measured in this way. If we can improve these data for a long time and analyze them in depth, we can roughly grasp the specific distribution of the coffee shop area. If we can further organize and classify the customer data systematically through the effective implementation of sales promotion activities, it will provide a lot of help to the training and maintenance of basic customers. Especially in the community coffee shop, the effective mastery of the business circle and the analysis of the customers are the important work of the successful operation of the coffee shop, so the management of the business area is an important part of the coffee shop business development.

Second, be sure to find your own customer base: identifying a customer base is very important for a coffee shop. To determine the customer base, first, we should consider the per capita income, second, we should consider the level of education, and third, we should consider the individual's work experience, experience, and the nature of the work unit.

As it is unable to attract all customers to come to spend money, it has become a necessary step for today's coffee shop operation to investigate and analyze the characteristics of the business area in terms of address, and then start to collect relevant information for the set customer object.

In general, the following factors must be taken into account when setting up a business circle and conducting customer surveys.

(1) the level of consumption in the business circle

(2) types of occupations of customers

(3) the composition of the age group of consumer groups.

(4) customers' reaction to fashion consciousness

(5) the consumption characteristics of customers

(6) the income and expenditure of the customer's family.

Through the investigation and analysis of these data, after understanding the characteristics of the business circle on the basis of address factors, we can then use this information to set customer objects.
