5 Common Coffee Myths, Debunked!

For many of us, coffee is a vital part of our daily routine. Yet despite its popularity, numerous misconceptions about coffee continue to circulate. Let's separate fact from fiction by examining some of the most common coffee myths.

Is coffee unhealthy?

Coffee has long captured the attention of health researchers, scientists, and wellness experts worldwide – and for good reason. 

Coffee is a rich source of essential nutrients, including vitamin B12 and magnesium, along with beneficial plant compounds called polyphenols. These components contribute to coffee's impressive health profile. Harvard's School of Public Health, a comprehensive study published in the New England Journal of Medicine, and other research describe the extent to which regular coffee consumption lowers disease risk. 

It's important to note that most concerns about coffee's health impacts actually center around its caffeine content, because caffeine may not be suitable for everyone. Some individuals might experience jitteriness, anxiety, or insomnia with higher caffeine intake. People with blood pressure concerns and people who are pregnant are commonly among those who have conversations with their doctor about caffeine. 

Here's the good news: if you love coffee but need to avoid caffeine, you don't have to give up your daily brew. San Francisco Bay Coffee offers decaffeinated options using the Swiss Water® Process, an environmentally friendly method that removes 99.9% of caffeine without using chemicals. This innovative 10-hour process uses pure hot water and a proprietary carbon filter to trap caffeine molecules while preserving the coffee's natural flavors. The result? All the pleasure and health benefits of coffee without the caffeine concerns.

Can coffee stunt your growth?

Despite being one of themost enduring coffee myths, there is no scientific evidence that coffee affects a person's height or growth. This misconception likely began from outdated studies suggesting a link between coffee and osteoporosis – but even this connection doesn't hold up under scrutiny.

Consider this: most human growth occurs before people typically start drinking coffee. Girls usually reach their full height between ages 15-17, while boys finish growing slightly later. Once bone growth is complete, it simply cannot be "undone" by coffee consumption.

While early studies suggested coffee drinkers might have an increased risk of osteoporosis, deeper analysis revealed that these coffee drinkers simply consumed fewer calcium-rich beverages like milk. It wasn't the coffee causing problems – it was the reduced intake of calcium and vitamin D in their diets.

If you're concerned about calcium intake, talk to your doctor about your diet. A splash of milk in your coffee or a balanced diet rich in calcium and vitamin D will hopefully be enough to offset any minimal effects caffeine might have on calcium absorption.

Does dark roast coffee have more caffeine?

This is a fascinating myth because it's based on a misunderstanding of the roasting process. Actually, light roast coffee typically contains slightly more caffeine than dark roast when measured by volume. During roasting, coffee beans lose water content and become less dense, while caffeine remains relatively stable.

When measuring by weight, the difference in caffeine content between light and dark roasts is negligible. The variation in caffeine content has much more to do with the type of coffee bean (Arabica vs. Robusta) and brewing method than the roast level.

Is coffee really a bean?

Here's a surprise for some coffee lovers: coffee "beans" aren't beans at all! They're actually the seeds of coffee cherries, which are the fruit of the coffee plant. These seeds are found in pairs inside the cherries, which is why they have that characteristic flat side.

The term "bean" likely stuck because of their appearance after processing. When the fruit is removed and the seeds are dried, they resemble legumes in shape and size. This misconception doesn't affect how we enjoy coffee, but it's an interesting botanical fact that highlights how much there is to know about our favorite beverage.

Does coffee dehydrate you?

While hydration needs can vary, and caffeine does have mild diuretic properties, moderate daily coffee intake does not cause dehydration. The myth about coffee's dehydrating effects likely stems from the fact that caffeine can increase urination in people who don't regularly consume it. However, regular coffee drinkers usually develop a tolerance to this effect, and their bodies adjust accordingly. Research has demonstrated that coffee can count toward your daily fluid intake, just like water or other beverages. If you have any concerns about hydration, talk to your doctor.
