There has been a lot of talk about the health benefits of coffee. Coffee can only prevent liver disease and cancer, dementia and multiple sclerosis, and prolong life.

Nevertheless, there are many rigorous studies that tend to examine the risks of caffeine consumption, especially for children and adolescents, pregnant and lactating mothers, and individuals with potential health conditions.

Is there any coffee in the head?

Coffee contains very complex molecules, the main of which is caffeine, which is a stimulant of the central nervous system. There are also other antioxidants that help clear free radicals in human cells, activate DNA repair, and prevent genetic mutations that cause cancer. However, this is completely good news because coffee also contains carcinogens.

After caffeine is absorbed in the intestines, it takes a long time to metabolize, and how to metabolize caffeine depends on our age. Its half-life-the time it takes to break down half of the caffeine in the body's system-is estimated to be between three and seven hours in adults. But for newborns, the figure is 65 to 130 hours higher. In addition, some people are affected by caffeine because of their genetic tolerance. For sex, oral contraceptive is thought to double the half-life of caffeine in the body. In pregnant women, caffeine stays in the body for a long time.

Other antioxidants and flavor molecules in coffee are chlorogenic acid, which is also found in apples, beans and other fruits, as well as vegetables and plants. They are absorbed by the intestinal tract, partly metabolized by intestinal microorganisms, and can play a strong antioxidant role in a series of cells.

The health benefits of coffee are attributed to caffeine and other antioxidant molecules, but are there other safety issues behind these claims?

Is caffeine safe?

Caffeine is safe for most consumers, but caffeine is all consumers. The groups most likely to have the potential negative effects of caffeine, as mentioned earlier, include pregnant and lactating women, children and adolescents, and patients who may have diseases such as cardiovascular disease.

Perverse sex

If the daily sexual intake exceeds 400 mg of caffeine, the risk of spontaneous abortion increases by 11%. If pregnant women eat caffeinated foods, they will increase the risk of giving birth to low-weight babies.

When a lactating mother brews coffee, caffeine is passed on to her baby through breast milk. Because babies metabolize caffeine much more slowly than adults, even small amounts can have significant effects on babies, such as irritability. However, the research is still inconclusive.

Children

Young children are also tolerated by caffeine because they weigh less than adults, which means that when they consume caffeine, the concentration of caffeine in the body is high per kilogram of body weight, and its effect lasts for a long time.

There is some evidence that teenagers who drink caffeine every day have sleep disorders, bouts and cynicism. In addition, energy consumption in children and adolescents is associated with changes in cardiovascular function, such as increased blood pressure, heart rate regulation, and increased risk of severe cardiac events.

In fact, the American Academy of Pediatrics recommends that children "want" caffeine and energy consumption.

Patients with cardiovascular / vascular diseases

There are still doubts about whether people with cardiovascular / vascular diseases should avoid coffee, but scientists do not "agree with the evidence, some studies are controversial about the link between caffeine and regular heartbeats, and other studies confirm this."

There is also evidence that caffeine may interact with some high blood pressure drugs to make the drugs more effective.

However, for healthy adults, a moderate intake of about 400 milligrams of caffeine a day seems to pose any health risk that may contribute to overall health and longevity.

So, if you are enjoying your first cup of coffee today, you can relax. However, if you are in today's Nth cup of coffee, you may need to consider cutting back.
