Welcome to today’s episode.

In this session, we take a closer look at one of the world’s most beloved — and most misunderstood — beverages: coffee. Despite decades of mixed messages, new scientific evidence paints a very different picture from the myths many of us grew up hearing.

Let’s separate fact from fiction.

Coffee has long found itself at the center of controversy. Some claim it raises blood pressure, others insist it dehydrates the body, and still others warn about mineral loss or increased disease risk. Yet when the scientific literature is examined carefully, a far more balanced story emerges — one that challenges many of these long-standing assumptions.

The discussion begins with one of the most widespread beliefs: the idea that coffee raises blood pressure and contributes to hypertension. According to a variety of studies, the relationship is almost the opposite of what many expect. While caffeine may cause a temporary rise in blood pressure for some individuals, long-term coffee consumption is consistently associated with a lower risk of developing chronic hypertension. People who drink coffee regularly tend to adapt to caffeine’s effects, resulting in no meaningful increase in baseline blood pressure. In many cases, coffee appears to offer a protective effect rather than a harmful one.

Another frequently repeated claim is that coffee dehydrates the body. This assumption dates back to the idea that caffeine acts as a diuretic. But research shows that habitual coffee drinkers develop a tolerance to this effect, meaning the body retains fluids just as effectively as it does with other beverages. When consumed sensibly, coffee contributes to daily hydration rather than undermining it.

Mineral loss is another myth that persists, particularly the fear that coffee leaches calcium or magnesium from the body. Current scientific findings do not support this idea. Any minimal impact on mineral excretion is far too small to cause deficiencies, especially in people with a varied diet. The notion that one cup of coffee can weaken bones or strip the body of nutrients simply does not align with what studies show.

The conversation also addresses concerns about cardiovascular health and cancer risk. These fears have been widespread for years, yet evidence repeatedly points in a different direction. Coffee consumption is consistently linked to a reduced risk of several cardiovascular conditions. Even more striking are the findings related to cancer: across numerous population studies, coffee is associated with a lower risk of developing several types of cancer. Its rich profile of antioxidants and biologically active compounds appears to play a protective role.

Taken together, these findings suggest that coffee is not the nutritional villain it has often been made out to be. Instead, it stands out as one of the healthiest commonly consumed beverages — provided it is enjoyed in moderation. Even individuals with hypertension, once warned to avoid coffee entirely, may safely include it in their diet according to current research.

The key message is simple: many of the fears surrounding coffee are rooted in outdated assumptions rather than current science. When the evidence is allowed to speak for itself, coffee emerges as far more beneficial than harmful.
