1. It can help you beat depression.
Morning coffee can boost moods, as anyone who has taken a cup of it will attest. The Harvard School of Public Health published a study last month in Archives of Internal Medicine that showed that fully caffeinated coffee drinkers have a 20% lower chance of developing depression. This study followed 10 years of women over a period of time. It found that the risk of depression fell as more coffee was consumed, up to six cups per day.
2. It can help you maintain a healthy weight.
After a meal, drinking an espresso or cappuccino is more than just a relaxing ritual. Chris Kilham, a medical researcher, founder and author of Psyche Delicacies, says that coffee after a meal causes the body to process the food more slowly. David Levitsky PhD, Cornell University professor of nutritional science, said that caffeine decreases the rate that the stomach dumps its contents into duodenum, a portion of the small intestinale where digestion takes places. It also increases metabolic rate. It is important to remember that java doesn’t work miracles. You can have a cup after dinner, but it won’t help you lose weight. However, it could be beneficial for your health in small ways.
3. It can increase fertility in men.
John Wilcox MD, FACOG is the managing partner and reproductive endocrinologist at HRC Fertility. “Studies have shown caffeine has a positive impact on sperm motility (the ability of sperm toward an egg)–and could increase [your chances of getting pregnant].” A University of Sao Paulo study found that coffee-drinkers had significantly higher sperm motility than non-coffee drinkers. It doesn’t matter how many cups you have, the only difference between coffee drinkers is that of non-coffee drinkers.
4. It could harbor bacteria.
You probably think of your kitchen sink and garbage disposal as the germiest areas in your home. Your coffee machine’s reservoir is also a top choice. Robert Donofrio PhD, director of NSF International’s microbiology laboratories, said that a study by NSF International, an international health and safety group, revealed that coffee machine reservoirs were “loaded with yeast organisms.” None of the volunteers that we spoke with cleaned their coffee reservoirs or disinfected them. It was a humid area of the machine and there was a lot of residual water. This led to bacterial growth. Follow the manufacturer’s cleaning instructions to clean your coffee machine. If there is no specific cleaning protocol, you can clean your coffee machine once a month using three to four cups of undiluted vinegar in the reservoir. After allowing the vinegar to sit for thirty minutes, run the vinegar through the unit. To remove any vinegar residue, add fresh water to the reservoir. The machine will run for two to three cycles.
5. It could lower the risk of developing skin cancer.
Your first line of defense against skin cancer should be to stay out of the sun, and to apply a generous amount of sunscreen regularly. A Brigham and Women’s Hospital study found that basal cell carcinoma risk was 20% lower for women who drink more than three cups per day. Men were at a 9% lower risk. The research didn’t show that coffee consumption reduces the risk of melanoma or squamous cells carcinoma, which is the most deadly form of skin cancer. It is therefore important to protect your skin outdoors.
6. It isn’t addictive.
Many people believe that caffeine makes them feel ill. However, Liz Applegate, PhD, is a faculty member at the University of California at Davis and the director of sports nutrition. She explains that caffeine does not make you addicted. “Caffeine can be reduced or eliminated from your diet, but it’s not addictive.” According to the World Health Organization, caffeine is a mild stimulant. If they cut down on their caffeine intake, serious coffee drinkers might experience fatigue and irritability. These symptoms are more common in people who drink 600 mg of caffeine per day (roughly six cups of coffee), but usually they resolve within a few days.
7. It does not necessarily cause stomach pain.
You might visit your doctor if you have ever blamed java in stomach discomfort. Lauren Gerson MD, MSc is an associate professor of medicine at Stanford University School of Medicine. She says that there is no evidence to support the claim that coffee causes ulcers, or worsens pain in patients who have had documented ulcers. There is also no evidence to suggest that coffee causes stomach pain in people with indigestion. Coffee can cause heartburn, Dr. Gerson says. This is because it stimulates the stomach’s production of gastric acid.
