You can't drink coffee with milk? Basic knowledge of coffee

According to the data, the current market size of coffee in China is about 70 billion yuan, and the annual growth rate remains above 15%. Experts predict that domestic coffee consumption will reach 300 billion yuan in 2020. China's coffee consumption per capita is currently 5 cups per year, far lower than Japan and South Korea's annual average of about 300 cups per capita, and also far lower than the world average of about 240 cups. Therefore, China is becoming the most potential coffee consumer in the world.

In fact, more and more city white-collar workers like to drink coffee, on the one hand, to eliminate fatigue, and on the other hand, the leisure function of coffee shops is becoming more and more popular. Do you know the three biggest coffee mistakes?

Misunderstanding 1 Instant coffee is low in trans fatty acids, and it doesn't matter if you drink more.

Many consumers assume that instant coffee and coffee mate are low in trans fats and that unless they drink more than 100 cups a day, they will not have a problem.

Explanation: Fan Zhihong, Ph. D. in food science from China Agricultural University, said that if it is a high-quality coffee mate, although the main ingredient of creamer is hydrogenated vegetable oil, the degree of hydrogenation is very thorough, and the content of trans fatty acids can be as low as 0.2%. According to China's regulations, it can be legally labeled as zero. However, this highly hydrogenated fat is high in saturated fatty acids, much higher than lard butter. So, if you drink too much instant coffee every day, trans fat is not a concern, but saturated fat should be careful, and sugar and caffeine intake will be too much, not very healthy.

Myth 2 Pure black coffee is very healthy and can be drunk

Coffee mate and instant coffee are added, so drink more pure black coffee and don't worry.

Explanation: Fan Zhihong said that pure coffee contains a lot of potassium and antioxidants, which is beneficial to the prevention of chronic diseases. However, after all, it contains more caffeine, caffeine metabolism ability varies from person to person, if you drink feeling flustered, insomnia, it is best not to drink. At the same time, coffee also has a certain stimulation to the stomach, gastric ulcer, acid excess, gastroesophageal reflux is also best not to drink.

Myth 3 Oxalic acid in coffee affects calcium absorption in milk

Coffee without partner and sugar, straight with milk OK? But also heard that coffee oxalic acid will affect the absorption of calcium in milk?

Explanation: Fan Zhihong said that adding milk directly to coffee is not a problem and does not hinder health. Although coffee does contain a small amount of oxalic acid, and caffeine also has diuretic effects, the amount of calcium loss caused by drinking a cup of coffee is small and not a concern. In contrast, much more calcium is obtained from milk than is lost to coffee, so the combined effect of coffee milk is beneficial to increasing calcium intake.
