Pros and Cons

As we described earlier, coffee itself has nothing bad in it, and, on the contrary,
it has many ingredients that are good for the body. Coffee does not only refresh
and clear your mind, according to scientific reports, antioxidants, caffeine and
other ingredients are good for your circulatory system and liver.
Of course, there are always different opinion on coffee advantages; World 02
Coffee Research reported: “Coffee is a new product in China, one of the reasons
why Chinese people don’t like to drink coffee is that they have wrong ideas about
how coffee affects health”. That is why we decided to clear this topic out for ev-
eryone, who is interested in the matter.

Can coffee cause insomnia?

Journal of Clinical Sleep Medicine tested 12 healthy sleepers, giving them
different amount of coffee, to see how it affects their sleep. What results showed
was that if you take 400mg of caffeine (2-3 cups of coffee) 3-6 hours before bedtime , it
will definitely disrupt your ability to drift off to sleep. Even if you take coffee 6
hours before going to sleep, comparing to normal sleeping duration, your sleep can
also be much shorter.
That is why one of test participant, Dr. Christopher Drake, suggest to avoid
any caffeine after 5pm, in order to have a healthy sleep. In other words, there is
no big difference for your body if you drink a cup of coffee after work or right
before going to sleep.

Do women need to reduce caffeine intake during pregnancy?

The U.S. Food and Drug Administration (FDA) has released a statement,
suggesting that pregnant women may need to reduce their caffeine intake.
The European Food Safety Authority (EFSA) in their “Scientific Opinion on
Caffeine” report, also pointed out that the daily caffeine dose for pregnant women
should not exceed 200 mg, while usually 1 cup contains about 80-85 mg. Moreover,
if a daily dose exceeds 300mg, it can lead to miscarriage or preterm baby birth . So
pregnant women can drink not only decaf, but also black coffee.
The main reasons of these side effects are:
① Caffeine running in the blood may cause insufficient blood supply for placenta,
provoking blood pressure and blood sugar to increase.
② Caffeine can slow mother’s uterus blood flow, thereby, reducing oxygen and
nutrients in the blood, affecting baby’s development.
③ Caffeine can speed up baby’s heart rate and metabolism, which harms the baby.
④ Fastened by caffeine, metabolism can also affect liver functions.
