Caffeine present in coffee increases nitric oxide production in the endothelium (the thin layer of cells that line the interior surface of blood vessels), which improves vascular muscle tone. Drinking caffeinated coffee increases short-term acute blood pressure, but blood pressure returns to normal after the caffeine gets metabolized. It has been found in various studies that 8 weeks of habitual coffee drinking lowers blood pressure readings significantly.
2. Coffee Improves Cholesterol Health
Coffee, like tea, contains a lot of antioxidants. The ones present in coffee are capable of raising the HDL cholesterol (good cholesterol), and lowering inflammation related to heart diseases.
3. Coffee Improves Reaction Time
A significant number of sports coaches have reported that caffeine in coffee is used by them in improving reaction time on soccer skill tests in athletes when they are sleep deprived.
4. Coffee Reduces Risk of Liver Cancer and Cirrhosis
Coffee contains a substance known as Praxanthine. This chemical slows down the growth of cell tissues in liver cancer and alcohol cirrhosis.
5. Coffee Reduces Risk of Type II Diabetes
Coffee has an inhibitory effect on toxic hIAPP (Human Islet Amyloid Polypeptide) formation which is found usually in the pancreas. This hIAPP is found in people having type II diabetes.
6. Coffee Prevents Parkinson’s Disease
Researchers have found that consuming five cups of coffee per day reduces the incidence rates of Parkinson’s disease.
7. Coffee Prevents Dental Cavities
A substance called tannins in coffee reduces the formation of plaque. This certainly prevents a person from having dental cavities. Drinking coffee also reduces the growth of bacteria like Streptococcus which are responsible for tooth decays.
8. Coffee Prevents Headaches
Caffeine present in coffee decreases the size of blood vessels before they can affect nerves in the brain. Hence, drinking coffee in the early stages of a headache minimizes the chances of a severe headache.
9. Coffee Reduces Workout Pain
Consuming caffeinated coffee an hour before vigorous exercise may help prevent pain while you’re working out. Caffeine in coffee blocks the activity of a chemical called adenosine that activates pain receptors in cells.
10. Coffee Keeps Skin Healthy
Coffee is believed to keep the skin healthy. Its antioxidants are known to prevent skin cancer and melanoma-related diseases. Coffee helps in getting rid of free radicals in the skin. This reduces the onset of skin-related problems such as acne and eczema.
