People often mistakenly believe that coffee can cause dehydration, but studies have shown that coffee can actually absorbed by our daily fluid for us to maintain moisture. Because caffeine is a mild diuretic, can lead to dehydration, so produce this common misconception.

 

A study reported in 1997, after drinking coffee in the subjects increased significantly compared with the same amount of pure drinking water in these subjects urine volume, and therefore came to this conclusion.

 

However, these subjects 5 days before the test were treated, has stopped taking caffeine, caffeine effectively out, in this case urine excretions increased therapeutic effect proves good.

 

British Dietetic Association and other expert bodies such as the United Kingdom are in favor of the British Nutrition Foundation: moderate drinking of coffee (4-5 cups a day) can help people absorb liquids every day, keep a clear head and the body of water to maintain. Similarly, one of North America conference communique also advises consumers to drink a variety of coffee drinks every day, of course, including coffee, to meet the needs of the body fluids. When you learn espresso moisture content exceeds 95%, you do not be surprised. Such a proposal at the British Nutrition Foundation has also been reflected, the association will milk, juice, tea and coffee are an important source of liquid.

 

Dr Sarah Schenker stressed:. "Many people still mistakenly believe that hot beverages, particularly hot coffee, hot day for our health disadvantage, because drinking hot beverages make us dehydrated but drinking hot beverages do not feel you'd expect so refreshing and actually leads to a big difference between dehydration. "after the" People drink a cup of coffee, the body will be the prevailing moisture status, retain all or most of the liquid. drinking coffee and people were drinking coffee quantity because tolerance is different, caffeine is also a diuretic produced its various. "

 

Like as hydrates, caffeine has been shown to help maintain a clear head and focus, and to promote a variety of tasks in performance. 20-30 minutes before exercise, drink a cup of coffee, so you can exercise more than 30% of the time. Caffeine contained in a cup of coffee can increase the secretion of adrenaline in the body, energetic people, and promote blood flow to the muscles and heart. The fact that caffeine can increase athletic performance, especially in endurance sports such as swimming, cycling and tennis effect is particularly evident.

 

For most people, the 400 mg daily intake of caffeine is appropriate - this is equivalent to drinking 4-5 cups of coffee a day. It depends on the size and every coffee concentration. Remember, in other foods also contain caffeine, such as tea, cola and chocolate.

 

For pregnant women, the British National Health Service recommended maximum limit: caffeine from a variety of foods shall not exceed 200 mg per day - roughly equivalent to 2-3 cups of coffee a day or substitutes.
