"Coffee can reduce the risk of heart disease and brain cancer, but how much should I drink every day to get better?" Zhang Jiayan, director of the Department of Biotechnology of Taipei Rongyou, shared in his face. According to two international studies, drinking coffee is not the better or the less, the better, but just the better, just like a "U-shaped curve", with 450 to 500 ml healthiest.

How much coffee is the most ideal?

Zhang Jiayan said that many people get up in the morning to drink a cup of coffee to kick off the new day, but some people will feel confused, "Is it really okay to drink coffee? Some say that coffee may be bad for health." The answer given by the latest large-scale research is exactly the opposite. Coffee is not only harmful, but also beneficial to health. The key is "how much is the ideal one?"

Two recent weight-level studies have pointed out that for the first time, the "U-shaped curve" of coffee's health benefits is clearly pointed out. First, a study in the Netherlands, which traced 1,719 patients with large kidney cancer for more than 6 years and found that drinking 3 to 5 cups of coffee a day (calculated at 125 ml per cup at Dutch standard) can clearly reduce the risk of cancer recurrence and death.

Drinking 2 to 3 cups of coffee a day can best reduce cardiovascular disease

In addition, a large-scale study of the UK Biobank that has lasted for 12 years also pointed out that drinking 2 to 3 cups of coffee a day (calculated as 150 ml per cup) can clearly reduce cardiac arrhythmia, cardiovascular disease and all-cause mortality. These two important studies jointly concluded that drinking coffee is the healthiest of 450 to 500 ml.

Why does drinking coffee have such a good effect? Zhang Jiayan pointed out that from the perspective of molecular medicine, modern people's life pressure, unhealthy diet or environmental factors can easily cause chronic inflammation in the cells. Chronic inflammation is like a "genetic opening" that is accidentally opened, making cells prone to aging or cancer.

And coffee contains rich green acids, polyphenols and ionic ions. These natural antioxidants can effectively reduce chronic inflammation in the body, close poor genes, reduce the chance of cancer recurrence, and at the same time stabilize the heart rhythm and maintain vascular elasticity. The appropriate amount of coffee every day can just calmly exert these benefits. Drinking too little is unclear. Drinking too much may cause excessive stimulation, resulting in palpitations or insomnia. This is what is called the "U-shaped curve effect".

Preferring to freshly ground black coffee

As for coffee types, Zhang Jiayan said that according to relevant research suggestions, the coffee type has higher polyphenols and antioxidant content, and the protection effect is also obvious. Avoid adding too much sugar or creamer and maintaining the natural flavor of coffee, you can get the best health benefits. The time to drink coffee is also very important. It is recommended to choose in the morning because this is the time when human reliance and detoxification is the most vigorous, which can more effectively exert the antioxidant effects in coffee, and avoid overdose in the afternoon or evening, which affects sleep quality.

Zhang Jiayan said that coffee, a seemingly ordinary drink, actually contains important health information. If you know how to master the appropriate amount, it is the way to nourish life in modern times. What we drink is not just a cup of coffee, but the art of life and the wisdom of health.
