Do you get palpitations if you drink too much coffee? Caffeine is just a scapegoat. The truth is...
Professional barista communication, please pay attention to coffee workshop (Weixin Official Accounts cafe_style)
Some people feel a rush of panic and palpitations after drinking coffee, which is commonly known as palpitations. In fact, this is a relatively subjective statement, which may be caused by many physiological changes, such as early atrial contraction, early ventricular contraction, tachycardia, etc., while normal early cardiac contraction has been confirmed by many studies and will be associated with cardiovascular disease morbidity and mortality.
Is caffeine really the main cause of heart palpitations? It's not true.
What is caffeine? It is a natural pest control mechanism that paralyzes insects after eating leaves and fruits. Relatively speaking, the higher the altitude of the plant, the less pests, it needs to produce less caffeine. And high altitude mountain day and night temperature difference is large, coffee beans in the day and night alternate cold and hot quenching, from flowering to maturity time is two months more than the lower altitude, so the texture is harder, the contents are richer, the aroma is stronger, the taste is more mellow, the flavor is better. Robusta, at lower altitudes, has about twice as much caffeine as Arabica. (Note: Robusta grows at an altitude of 0-700m, mostly used in commercial beans, or instant coffee, canned coffee, etc.) )
Usually drinking eight cups of coffee in a row will cause the body to heat up, sweat, eyes straight, known as the first phase of the coffee overdose reaction, after such a situation will continue to drink palpitations, heart load, known as the second phase of the coffee overdose, so many people usually think that palpitations are the second phase of the absorption of large amounts of caffeine. However, many people often drink a few mouthfuls of coffee and directly produce palpitations, forcibly skipping the first stage of physiological reaction. Moreover, many cola and energy drinks on the market contain caffeine, but few people have heard of palpitations after drinking a few mouthfuls of cola!
In a study published in the Journal of the American Medical Association, 22 patients with ventricular tachycardia or ventricular fibrillation had their electrocardiograms monitored one hour before and after ingesting 275mg of caffeine (equivalent to one to two cups of coffee) and found that caffeine did not induce or aggravate arrhythmia.
Another study of 50 patients with arrhythmia, who were divided into two groups, one group drank decaffeinated coffee and the other group drank coffee with 200mg caffeine (decaffeinated coffee with caffeine added), and monitored for 3 hours. The results also did not find any difference between the two groups of patients in palpitations.
It can be inferred that the biggest culprit directly causing palpitations is not caffeine, but certain alkaloids that are highly toxic to the body.
Highly dangerous alkaloids are most likely to be produced when:
1. Coffee beans are picked before they are ripe
2. Coffee beans are not roasted properly
3. Not properly baked or preserved
In addition, drinking uncoked coffee will not cause palpitations and physical burden. According to research coffee coking comes from: baking coking, grinding beans coking, packaging coking, quenching coking four kinds:
1
baking coking
Many coffees on the market are low-grade coffee beans at medium and low altitudes. Due to multiple harvests in a year, coffee flavor and taste are insufficient, so coffee is deliberately roasted to make you smell rich (sometimes with chemical flavor), but you do not know that soybean oil has been coking, which is easy to cause palpitations and body burden.
2
bean-grinding
Commercial bean grinders are used in the market. When a large number of extremely high speed grinding beans are produced, high temperature will damage the original taste and aroma of coffee, resulting in coking phenomenon, which is harmful to health.
3
package coking
When the coffee is sealed, when the fresh-keeping tank has a pressure greater than the positive air, the coffee will automatically generate trace heat energy and coke itself.
4
extractive coking
Common Italian coffee machine, siphon pot extraction coffee when the water temperature is too high or in the pot for too long, and other bad coffee extraction methods, due to high temperature, high pressure or excessive extraction, easy to produce unpleasant ingredients (impurities), released into the coffee, detrimental to health, excessive absorption is easy to palpitations, sleep, and harm the body, must not pay attention.
Therefore, to avoid palpitations, we need to choose the right, high-quality coffee. Here are some suggestions for reducing harmful alkaloids and avoiding coking:
1, give priority to the selection of washing method of coffee beans. Washing treatment method has the effect of screening immature beans and defective beans after washing process, and the maturity of washed coffee beans is relatively uniform.
2. Choose coffee beans that are roasted evenly and not too deep or too shallow. Roasting uniformity can be judged by observing surface color uniformity and breaking coffee beans to observe internal and external color differences.
3, try to choose fresh roasted coffee beans, try to choose bags with one-way exhaust valves. Ripe coffee beans without a roasting date are hooligans.
4, pay attention not to grind beans for a long time a lot of grinding, grinding disc heat is will make coffee powder coking. Buy their own hand-grinding machine is now cooked on the ground is quite good.
5. When extracting coffee, proper attention should be paid to grinding degree and water temperature to avoid over-extraction. Don't feel that coffee powder does not try to extract more flavor as if it is wasted, and feel that it is a big loss.
Summary:
There is a saying in the coffee world: "The initiator is alkaloids, caffeine is just a scapegoat." So don't equate palpitations with caffeine. Maybe you need to care about maintaining good quality coffee.
