Does drinking coffee make people younger? This viewpoint comes from a recent study that found chlorogenic acid in plants such as coffee can inhibit skin aging and reduce inflammation levels.
Chlorogenic acid is a natural polyphenolic compound widely present in various plants, including coffee, tea, Eucommia ulmoides, honeysuckle, potatoes, apples, etc. It has various biological activities such as antioxidant and anti-inflammatory. In addition, chlorogenic acid can also regulate glucose, lipid metabolism, and glycolysis.
Chlorogenic acid was discovered by scientists in 1932, and coffee is the plant with the highest content of chlorogenic acid in nature. It is interesting that the content of chlorogenic acid in coffee is directly proportional to the content of caffeine, meaning that the higher the chlorogenic acid content, the higher the caffeine content.
It is worth noting that chlorogenic acid is not a single compound, and there are at least six isomers. The two most relevant chlorogenic acids to coffee flavor are “monocaffeoylquinic acid” and “dicaffeoylquinic acid”. The former is almost completely degraded during roasting, while the latter mostly remains in ripe beans, becoming an important source of coffee bitterness.
Chlorogenic acid, also known as coffee tannic acid, has biological activities such as antioxidant, anti-inflammatory, antibacterial, and antiviral. It was first discovered and extracted from raw coffee beans. Today, coffee beans and their products are still the main food source of chlorogenic acid in common foods.
A cup of coffee contains approximately 70-350 milligrams of chlorogenic acid, even decaffeinated coffee contains the same amount. In addition, the process of roasting coffee beans can lead to a decrease in chlorogenic acid, with light roasted coffee beans retaining more chlorogenic acid than deep roasted coffee beans.
In addition to coffee, there are also some foods that contain rich chlorogenic acid, which can be chosen according to personal preferences, such as honeysuckle, chicory, blueberries, sunflower seeds, cherries, eggplants, apples, pears, hawthorns, potatoes, etc.
5 precautions to pay attention to when drinking coffee
Some people say that chlorogenic acid has so many benefits, so drink more coffee! Although coffee is good, it also contains many other ingredients. Drinking it right can have the best effect.
There are 5 precautions to pay attention to when drinking coffee.
1. Don’t drink coffee on an empty stomach
Many people have the habit of drinking a cup of coffee on an empty stomach first in the morning, which not only reduces appetite but also stimulates the digestive system. It is recommended to drink coffee after breakfast or lunch, as it can aid digestion.
2. Don’t add sugar to your coffee
Many people like to add sugar and coffee companions to their coffee. If milk can replace sugar and coffee companions, not only will it have a sweet and smooth taste, but it can also supplement protein and calcium. Coffee companions have a high fat content and contain hydrogenated vegetable oils, which are not conducive to health.
3. Don’t drink coffee too late
Caffeine takes 8 hours to be completely excreted from the body. It is recommended not to drink coffee at night as it can affect sleep quality. It is best to drink it before 3 pm in the afternoon.
4. Don’t drink coffee too hot
Drinking coffee requires careful attention to detail. Drinking it slowly is more in line with the metabolic characteristics of caffeine, which can effectively enhance its refreshing effect. On the other hand, it can also allow you to enjoy the rich and mellow taste of coffee. Especially for coffee that is too hot, don’t rush to drink it.
5. Don’t drink too much coffee
It is generally recommended to consume no more than 250 milligrams of caffeine per day, equivalent to 2-3 cups of coffee.
