The weight loss effect of drinking "raw coffee" is better than drinking black coffee?!
Nowadays, people's pursuit of coffee can no longer be satisfied with roasted coffee beans. Recently, a coffee shop in Nagoya, Japan launched "raw coffee"! And said that this coffee is deeply loved by health scholars and celebrity models!
According to the coffee shop's website, "raw coffee" is made from a mixture of raw coffee beans and roasted coffee beans ~ according to the Japanese Analysis Center, one cup of raw coffee a day can achieve a good antioxidant effect.
It's weird, right?! Won't it smell good when all the coffee beans are cooked properly? And the flavor of coffee is only reflected after baking! It doesn't smell good enough.
Because drinking "raw coffee" is not for the flavor of coffee, not just for anti-oxidation, but to lose weight! I know what everyone is trying to say, whether black coffee can also lose weight! ) leak! The effect of black coffee on weight loss is not! Enough! Fierce!
The practice of "raw coffee" is not created by this coffee shop. As early as a few years ago, some scholars began to study the effect of "raw coffee". In order to estimate the weight loss effect of "raw coffee" and "black coffee", the researchers conducted a four-week experiment. Half of the participants drank a cup of raw coffee before breakfast, while the other half drank a cup of black coffee before breakfast.
After drinking for two weeks, the average weight of people who drank "raw coffee" lost about 1.59 kilograms, while those who drank "black coffee" lost about 0.13 kilograms. After drinking "raw coffee" for four weeks, the average weight of people who drank "raw coffee" lost about 2.01 kilograms. On the other hand, the average weight of people who drank "black coffee" lost about 0.25 kg.
It can be seen from the experimental results that although drinking "black coffee" can also achieve the effect of losing weight, the effect is obviously not comparable to that of "raw coffee". The reason is that chlorogenic acid in raw coffee beans can improve insulin sensitivity, regulate sugar and lipid metabolism, and play an important role in the prevention and treatment of obesity, diabetes, metabolic syndrome and other chronic diseases.
So why is it that raw coffee beans are rich in chlorogenic acid, while roasted coffee beans are not? Chlorogenic acid is the most abundant organic acid in coffee beans. For coffee fruits, chlorogenic acid exists for insect resistance. What is the principle? Ah! It tastes terrible! Yes, it is because it tastes bad, chlorogenic acid tastes sour and hinders the mouth, so insects do not like to eat coffee fruits with high chlorogenic acid content.
In general, varieties such as Robusta grow at low altitude and are easy to attract insect pests, so Robusta coffee beans themselves will have a lot of chlorogenic acid, which will hinder the existence of other flavor substances. On the other hand, Arabica coffee beans are grown at high elevations, and the temperature difference between day and night is not prone to insect pests, so they do not need to secrete a lot of chlorogenic acid to protect themselves, and make more room for other flavor substances. This is why Arabica coffee beans taste better than Robusta coffee beans.
The best way to remove the acerbity of chlorogenic acid is to roast the coffee beans at high temperature. Chlorogenic acid will be degraded into quinic acid at high temperature, and quinic acid itself is not volatile, but it will have a bitter taste. Therefore, the presence of an appropriate amount of quinic acid will increase the alcohol thickness of coffee, and excessive quinic acid will bring bitter taste to coffee.
After reading this paragraph, are you imagining that "raw coffee" will taste sour and astringent? If it is really this kind of taste, probably no one will want to promote "raw coffee". According to friends who have drunk it, "raw coffee" tastes like nuts and feels like wheat tea. It tastes like wheat tea and is only about as strong as black coffee. Although it doesn't taste as bad as everyone thinks, it's not a good coffee either.
Although "raw coffee" has a significant weight loss effect, drinking is also very light, but after all, it is still coffee, so it can not be used as water to drink! Raw beans also contain caffeine and caffeine. Drinking too much coffee will increase hunger and be counterproductive. At the same time, excessive caffeine intake will lead to excessive excitement of the central nervous system and heart discomfort.
