For those who have never had a cup of coffee without sugar, you might say that's crazy, but what if I told you that drinking coffee without sugar can prolong your life, help fight diseases, or make you smarter?
Research shows that drinking unsweetened coffee twice a day can have excellent health benefits. I've already told you about the benefits of specialty coffee , so now I'll give you 11 benefits of drinking unsweetened coffee and how it can improve your health.
1. Improves memory and concentration
Coffee stimulates the central nervous system thanks to caffeine, a compound that blocks adenosine (an inhibitory neurotransmitter) and, consequently, improves alertness and concentration.
Studies have shown that caffeine improves cognitive performance, especially in short-term memory tasks. Consuming one or two cups a day can be a good habit to keep your mind active and alert.
2. Prevents tooth decay
Unsweetened coffee has antibacterial and anti-adhesive properties that help reduce plaque buildup. This means it can help prevent cavities and improve oral health, as long as you don't add sugar or creamers that counteract its benefits.
3. Promotes digestive health
Coffee acts as a stimulant for the digestive system and has mild laxative effects. Furthermore, drinking coffee without sugar helps eliminate bacteria and toxins through urine. It has also been suggested that it may help slow the proliferation of intestinal parasites.
4. Protects liver health
One of the benefits most supported by science is its positive impact on the liver. Regularly drinking unsweetened coffee has been associated with a lower risk of liver diseases such as cirrhosis, fatty liver disease, and liver cancer.
Drinking between 2 and 4 cups of coffee a day can reduce the risk of liver disease by more than 60%.
5. Stimulates metabolism and helps with weight loss
Coffee contains very few calories per cup, and with no added sugar, it provides no fat or carbohydrates. In addition, caffeine stimulates thermogenesis, which speeds up metabolism and promotes fat burning.
Drinking a cup of unsweetened coffee before exercise can boost your physical performance and promote weight loss.
6. Reduces the risk of Alzheimer's and dementia
Regular consumption of unsweetened coffee has been linked to a lower incidence of neurodegenerative diseases such as Alzheimer's. It also appears to have a protective effect against mild cognitive impairment.
7. Improves cardiovascular health
Drinking coffee in moderate amounts without sugar can reduce the risk of heart failure, stroke, and coronary heart disease. It also improves blood vessel function and reduces inflammation.
8. Reduces the risk of type 2 diabetes
Research has revealed that those who drink coffee daily have a lower risk of developing type 2 diabetes. This benefit is due to compounds such as chlorogenic acids, which improve insulin sensitivity.
Of course, this benefit is lost if it is not sugar-free coffee .
9. It can reduce the risk of cancer
Unsweetened coffee contains antioxidants that help protect cells from oxidative damage. Studies have linked coffee consumption to a lower incidence of certain types of cancer, such as liver, prostate, and colon cancer.
10. Provides powerful antioxidants
Coffee is one of the main sources of antioxidants in the Western diet. These compounds fight free radicals, which can damage cells and contribute to aging and chronic diseases.
11. Helps fight cellulite
Unsweetened coffee can improve blood circulation and help reduce localized fat deposits, which can diminish the appearance of cellulite when combined with diet and exercise.
