10 Coffee Myths Busted by Science

Coffee is one of the most beloved beverages in the world, but it’s also surrounded by myths and misconceptions. From its effects on health to brewing techniques, let’s debunk some of the biggest coffee myths with science-backed facts.

1. Myth: Coffee Dehydrates You

Truth: While coffee is a diuretic, moderate consumption does not lead to dehydration. Studies show that coffee contributes to daily fluid intake similarly to water.

2. Myth: Dark Roast Has More Caffeine

Truth: The roasting process affects flavor more than caffeine content. Lighter roasts actually retain more caffeine because they are roasted for a shorter time.

3. Myth: Coffee Stunts Growth

Truth: There is no scientific evidence that coffee affects bone growth or height. This myth likely originated from early misconceptions about caffeine.

4. Myth: Espresso Has More Caffeine Than Drip Coffee

Truth: While espresso is more concentrated, a standard cup of drip coffee actually contains more total caffeine due to its larger serving size.

5. Myth: Coffee Sobers You Up

Truth: Coffee may make you feel more alert, but it does not speed up alcohol metabolism or reduce intoxication.

6. Myth: Pregnant Women Should Avoid Coffee Completely

Truth: While excessive caffeine intake is discouraged during pregnancy, moderate consumption (under 200mg per day) is generally considered safe.

7. Myth: Coffee Causes Heart Disease

Truth: Research shows that moderate coffee consumption is not linked to heart disease and may even have protective cardiovascular benefits.

8. Myth: Adding Milk or Sugar Ruins Coffee’s Benefits

Truth: While black coffee has the most antioxidants, adding milk or sugar does not negate its health benefits—it just changes the nutritional profile.

9. Myth: Instant Coffee Is Low Quality

Truth: Specialty instant coffee is now made from high-quality beans using advanced techniques, offering great flavor and convenience.

10. Myth: Coffee Is Addictive Like Drugs

Truth: While caffeine can create dependence, it does not cause the severe physical addiction associated with drugs. Withdrawal symptoms are mild and temporary.
