Coffee: The culprit for the decline of estrogen

Coffee is a drink that many people cannot live without every day. It can refresh the mind and increase concentration. However, recent studies have shown that excessive coffee intake may have a negative impact on estrogen levels in women. This article will explore the reasons why coffee reduces estrogen and analyze the possible health risks it may bring.

1. Caffeine and estrogen

First, we need to understand some basic knowledge. Estrogen is one of the important sex hormones in women, and plays a key role in maintaining the menstrual cycle and promoting breast development. However, with age and menopause, the level of estrogen naturally secreted in women will gradually decrease.

Studies have found that excessive caffeine intake can interfere with the body's normal absorption and metabolism of estrogen. Specifically, the enzymes responsible for metabolizing hormones in the liver are inhibited by caffeine, causing estrogen to stay in the body for a longer time. This means that excessive caffeine intake may cause women's estrogen levels to continue to rise.

2. Caffeine and the menstrual cycle

Not only that, but studies have also found a link between excessive caffeine intake and menstrual cycles. A study of female college students found that women who consumed more than 300 mg of caffeine a day (equivalent to about three cups of espresso) were more likely to experience irregular menstruation and amenorrhea.

This effect is mainly due to the interference of caffeine with ovarian function. The ovaries are important organs for the secretion of estrogen, and excessive caffeine intake can inhibit ovarian function and interfere with the normal ovulation process. These changes may lead to menstrual cycle disorders, infertility and other problems.

3. Health risks

In addition to affecting the menstrual cycle, high estrogen levels are also associated with a variety of health problems. For example, after menopause, a woman's estrogen levels drop, which may lead to osteoporosis. However, excessive caffeine intake can cause women's estrogen levels to continue to rise, increasing the risk of osteoporosis.

In addition, high estrogen levels are also associated with the occurrence of specific female cancers such as breast cancer and endometrial cancer. Although there is no direct evidence that caffeine can cause these cancers, excessive caffeine intake may increase estrogen levels in the body and further increase the risk of these cancers.

4. How to reduce the impact

If you are a woman who loves to drink coffee and is worried about its adverse effects on the decline of estrogen, the following suggestions may help you:

- Control your intake: Moderate coffee consumption is safe and healthy. Consuming 200-300 mg (about 2-3 cups) of caffeine per day is considered to be within a relatively safe range.

- Adjust your timing: Avoid excessive caffeine intake during menstruation or ovulation, as estrogen levels in women are higher during these periods.

- Find alternatives: If you're concerned about the effect of caffeine on estrogen, try decaffeinated drinks such as herbal teas or juices.

in conclusion

Although coffee is good for stimulating your brain, excessive consumption may have a negative impact on estrogen levels in women. Controlling intake, adjusting timing, and finding alternatives are effective ways to reduce this effect. If you have any concerns, please seek professional advice from your doctor.
