Side Effects Of Coffee
Coffee is a popular beverage in the world, and many people like to have a cup of coffee in the morning to have a refreshing taste. However, regular consumption of coffee can bring many side effects to our body as follows:
Researchers’ statistics showed that women who drink at least one cup of coffee every day have a higher risk to suffer from infertility than women who don’t drink coffee. Experts also investigated the coffee drinking habits of 104 women and 50 of them were not easy to conceive. Some fertility experts believe that the sample of this test is too small and this result could not finally confirm the relationship between coffee and maternity. However, the infertility associated with caffeine should be considered if no other obvious reasons can be found.
Scientists from Boston University School of Public Health have done a four-year-long research based on 858 women ranging from 45 to 69 years old who suffer from myocardial infarction for the first time, and 858 women who never suffer from any heart attack. Results showed that drinking 5 or more cups of coffee a day may increase the risk of myocardial infarction by 70%, and this rate will rise with the increased number of drinking coffee within a day.
Researchers from the University of California carried out a study of 980 older women ranging from 50 to 98 years old. The results showed that drinking two or more cups of coffee in a day will result in a reduced bone mineral density of the hip and spine regardless of age and obesity. The level of reduction is based on the length of time and amount to drink. The reason is that caffeine can combine with free calcium in the human body and finally pass out of the body with the urine. Decrease in free calcium in the body will surely cause the decomposition of calcium which may lead to osteoporosis.
Researchers from Finland and United States discovered that people from their country will consume more coffee than any other countries. As a result, more people in their countries are suffering from diabetes than other countries as well. Actually, Finland is the country having the highest coffee consumption in the world, and it also have the highest percentage of patients suffering from diabetes in the world. Coffee consumption is also high in other Nordic countries which also lead to a high number of diabetes patients. In contrast, Japanese have the lowest consumption of coffee in the world, and percentage of patients suffering from diabetes are also the lowest.
