Why Your Coffee Addiction Isn’t So Bad for You

4 minute read

Knocking back a daily cup of joe (or several) delivers more than a jolt of energy. That morning brew comes with a host of health benefits, according to research. Here’s how coffee can benefit your body and your brain.

1. Coffee may decrease your risk of depression. Drinking four or more cups per day could decrease the risk of depression in women, according to a study from the Harvard School of Public Health. The study examined the coffee habits and depression rates of 50,739 women over 10 years. Coffee drinkers had a 20 percent lower chance of developing depression later in life. Drinking two to four cups daily also appears to lower the risk of suicide by 50%, according to another Harvard study.

2. Coffee might help prevent skin cancer. Drinking four or more cups of coffee daily may lower your risk of cutaneous melanoma, the leading cause of skin-cancer death in the U.S., by 20 percent, according to a new study published in the Journal of the National Cancer Institute. Researchers followed nearly 450,000 cancer-free participants over 10 years. Overall, those who drank more saw less cutaneous melanoma. Four daily cups of coffee can also reduce the risk of Alzheimer’s, according to previous studies.

3. Smelling coffee can bust stress. When rats smelled coffee beans, genes connected with healthful antioxidants and stress-reduction were activated, according to researchers from Seoul National University in South Korea. No, you’re not a rat—even if you’re in the rat race—but the stress-busting benefits may be one reason your morning latte smells so delicious.

4. Coffee might help fight obesity. A compound found in coffee, chlorogenic acid (CGA), could help ward off obesity-related diseases, according to researchers at the University of Georgia. In a study of mice, CGA prevented weight gain, reduced inflammation, helped maintain normal blood-sugar levels, and kept livers healthy. Gradually increasing your coffee consumption can also lead to a lower risk of Type 2 diabetes, according to previous research.

5. Coffee may prevent Parkinson’s disease. Men who did not drink coffee were two to three times more likely to develop the disease than men who drank four ounces to four cups per day, according to a study published in Journal of the American Medical Association. Though there are treatments to slow the progression of Parkinson’s, which targets the body’s nervous system and causes tremors, there’s no cure, so prevention is key.

6. Coffee could boost your workout. Caffeine increases the number of fatty acids in the bloodstream, which raises overall endurance, because your body doesn’t have to burn carbs so fast, The New York Times reports. Weightlifters who drank caffeine before their workouts stayed energized longer than those who did not, according to another small study.

QUIZ: Should You Eat This or That?

Which is better for you: A 1/2 cup of ice cream or 3 scoops of sorbet?
Which is better for you: Half cup of ice cream or 3 scoops of sorbet?Getty Images (4)
Answer: A 1/2 cup of ice cream
Answer: A half cup of ice cream If you eat what you’re craving, you’re more likely to feel satisfied and eat less. And scoop for scoop sorbet contains twice the sugar with none of the filling dairy protein and fat.Getty Images (5); Gif by Mia Tramz for TIME
Which is better for you: Real butter or spray on fake butter?

Answer: Butter
Answer: Butter Serving size for spray butters (even low-calorie ones) are around a 1/3 second spray. What on earth does that mean? You're better off using a small amount of real butter as opposed to guessing how much you're using of the mystery melange of up to 20 ingredients.Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: A sirloin burger or a turkey burger?
Which is better for you: A turkey burger or a sirloin burger?Getty Images (2)
Answer: Sirloin burger Restaurant turkey burgers are often made with dark meat and the skin, so they’re not necessarily better for you (and for the record, they aren't low-fat). You can get a sirloin burger that’s 95% lean meat and gives you 20 g of protein. Just be careful with the toppings.Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: Almonds or pretzels?

Answer: Almonds
Answer: Almonds Almonds are high in protein, fiber and fat and will keep you feeling fuller longer. Give high-sodium pretzels about an hour and you'll feel hungry again thanks to the high-carb no-fat or protein content.Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: Eggs or Special K?

Answer: Eggs
Answer: Eggs In the morning, you want a meal that will fill you up. Eggs offer protein and fat for satiety, but Special K cereal really only offers carbs and, well, air. If you want carbs to kick off the day, you're better off pairing eggs with a slice of 100% whole grain toast. Getty Images (1); Gif by Mia Tramz for TIME

Which is better for you: Fat free salad dressing or regular salad dressing?Tara Johnson for TIME
Answer: Regular salad dressing
Answer: Regular salad dressingTo absorb fat soluble vitamins like Vitamins E and K in vegetables you need to consume them with a fat to aid nutrient absorption. Fat-free dressing, meanwhile, is low-calorie but gets its flavor from added sugar and salt.Tara Johnson for TIME (5); Gif by Mia Tramz for TIME

Answer: Dark chocolate “People tend to believe fat free is calorie free,” says Keri Gans, a registered dietitian in New York City. “Go for the real thing.” Fat free cookies may be lower in fat, but higher in other ingredients like sugar. Try a nice piece of dark chocolate for those antioxidants.

7. Coffee may help your hearing. Regularly consuming caffeine may help prevent tinnitus, a persistent ringing in the ear. Women who drank one and a half cups of coffee a day were 15% more likely to develop tinnitus than those who drank four to six cups, according to a study of 65,000 women published in the American Journal of Medicine.

8. Coffee could lead to a healthier liver. Drinking both caffeinated and decaffeinated coffee may lower liver enzymes associated with inflammation, according to a 28,000-person study conducted by researchers at the National Cancer Institute. Participants who drank at least three cups of coffee per day showed lower levels of the potentially harmful enzymes than those who did not drink coffee.

9. Coffee might help you live longer. Drinking two to six (or more) cups of coffee per day could lower the risk of dying by 10 percent for men and 15 percent for women, according to a study of over 200,000 men and 170,000 women (ages 50 to 71) in The New England Journal of Medicine. (The data was adjusted to discount the effects of unhealthy habits, such as smoking, since regular coffee drinkers also tended to be regular drinkers and meat-eaters.)
