When it comes to the link between coffee consumption and life expectancy, there are two popular, different opinions. On the one hand, this beverage makes you live shorter; on the other hand, it increases life expectancy. In fact, these two views do not conflict with each other and the trick here is to limit caffeine consumption. That’s to say, caffeine overdose tends to make you look older while moderate caffeine intake can keep your skin looking more youthful.
Numerous studies have confirmed that drinking coffee can prolong life. Indeed, just like dark chocolate and red wine, this is also one of anti-aging super foods. Many health experts believe that free radicals play an important role in the aging process. In other words, you can stay healthy and live longer if your body can maintain the balance of producing and removing free radicals. And scientific experiments show that drinking coffee is a simple anti-aging practice. However, it doesn’t necessarily mean that the more you drink it the longer you live. Apparently, it’s far more complicated than that.
Free radicals are one of known culprits for aging and various diseases due to functional decline. So, in order to maintain good health and longevity, what you need to do is to inhibit oxidation, trying to eliminate all free radicals from your body. Unfortunately, molecules responsible for aging and tissue damage proliferate due to many reasons, such as automobile exhaust, environmental pollutants, smoking, fried food, unhealthy fats, and so on. Numerous studies have demonstrated that excessive free radicals will be produced during the process of many diseases. For example, diseases like cancer, diabetes, or Parkinson’s are somehow linked to too many harmful molecules inside the body.
Coffee contains two main components that affect health, and they are antioxidants and caffeine. Both of them are good for health and anti-aging. For example, antioxidants can help the body repair cell damage caused by free radicals, and caffeine can help protect against Parkinson’s disease and brain aging-related issues. So, drinking coffee can effectively promote health while reducing the risk of chronic diseases.
There is oxidation in the human body each day. If you can effectively delay this oxidation process, you will effectively delay aging and reduce the incidence of chronic diseases. Many of you know that green tea has antioxidant effects, but have no idea that coffee is rich in natural antioxidants too. Studies have shown that these two foods have nearly the same antioxidant activity and free-radical scavenging ability. For example, UV-induced damage can be very serious, but coffee protects against UV damage. As mentioned above, Joe is rich in antioxidants, and it has shown good antioxidant activity in all anti-oxidant models. And the antioxidant capacity may slightly vary from variety to variety.
Antioxidant content in coffee is 150-550 mg in a cup. Drinking 300 milligrams of caffeine per day is safe for the average adult. That being said, you are allowed to drink 3-5 cups a day, the equivalent of 6 cups of tea or 8 cans of coke. It is important to note that caffeine is not always the same in a cup of it. For example, every cup of instant coffee contains 30-120 mg of it.
In addition to caffeine, one of the most active ingredients, coffee also includes other useful substances, such as organic acids, fats, alkaloids, minerals, potassium, magnesium and iron. Especially, the linoleic acid can prevent skin aging, make skin more elastic, and reduce inflammation. And dermatologists have confirmed that coffee has anti-inflammatory and antioxidant properties. In fact, it can prevent the damage to cells caused by free radicals. So, it will help brighten and tighten skin since it helps reduce pigmentation. In addition, it can also help reduce skin damage caused by the sun.
Although studies have found that coffee has a lot of benefits, but you cannot ignore the potential harm of drinking it. The typical one is allergies in some individuals. It can also cause insomnia and nervousness, especially in the case of overdose. If you are pregnant, it is recommended to drink no more than a cup of coffee (200 mg) a day. Otherwise, it will increase the risk of miscarriage. Besides, nursing mothers should also consider the total caffeine intake because excessive intake can cause infant irritability and insomnia.
