Discover the benefits of unsweetened coffee below:
1. Decreases Risk of Diabetes
Data from the Harvard T.H. Chan School of Public Health reveals that coffee consumption lowers the risk of type 2 diabetes by 8% in women. While adding any sweetener may increase your blood sugar levels, pure coffee does not.
However, some studies also indicate that caffeine can impair insulin sensitivity. Therefore, diabetics should consume unsweetened coffee in moderation and after consulting with their doctor.

Unsweetened Coffee Offers Countless Benefits
2. Reduces Risk of Heart Disease
According to the World Health Organization (WHO), cardiovascular diseases are the leading cause of death globally. Studies have found that caffeine intake can lower the risk of heart disease.
A study published in the Ochsner Journal showed that coffee consumption could be beneficial for your heart. However, caffeine only has this effect when consumed without sugar.
3. Enhances Memory
Do you often forget things or find it hard to memorize information? Sipping on a cup of coffee may improve your memory.
A study by Johns Hopkins University found that consuming pure coffee can help enhance your memory.
4. Aids in Weight Loss
If you’re trying to lose weight, consider incorporating unsweetened coffee or black coffee into your diet.
A study published in the Critical Reviews in Food Science and Nutrition journal showed that caffeine intake could help reduce body mass index (BMI) and overall weight.
Caffeine consumption increases thermogenesis, boosting energy output and the body’s metabolism, thus helping you burn more calories.
5. Decreases Risk of Fatty Liver
The digestion of caffeine leads to the production of a substance called paraxanthine, which inhibits scar tissue formation that contributes to cirrhosis.
According to a study published in the Frontiers in Pharmacology journal, this substance could be beneficial in the fight against hepatitis C, alcoholic cirrhosis, non-alcoholic fatty liver disease, and liver cancer.
6. Prevents Tooth Decay
Drinking coffee without added sugar or cream can help reduce bacteria in the mouth and lower the risk of tooth decay. A study published in the Journal of Conservative Dentistry found that drinking coffee without any additives decreased the risk of dental caries.
7. Controls Blood Pressure
High blood pressure can increase the risk of heart disease, so it’s important to keep it in check.
According to a study published in the Nutrients journal, drinking coffee can lower blood pressure. However, the researchers from the same study advise against consuming moderate amounts of coffee, as too much can also increase blood pressure levels.
Note: When drinking unsweetened coffee
– Those with sensitive stomachs or digestive issues may find that it irritates their stomach and makes their condition worse. It can cause bloating, constipation, gas, and diarrhea.
– If you are allergic to caffeine, avoid drinking or eating these food products, as they may trigger an allergic reaction and lead to other complications.
