Nutritionists are advising coffee drinkers to reconsider their morning routine regarding when to have their first cup. Instead of drinking coffee immediately after waking up, experts suggest waiting at least 30 to 90 minutes to maximize the benefits of caffeine. This is referred to as the '45-minute rule' by Spanish nutritionist Pablo Ojeda, who emphasizes that having caffeine too soon after waking can be counterproductive.

The timing of coffee consumption can significantly impact its effect on the body. Nutritionists explain that cortisol levels, which help manage metabolism and immune response, are typically highest shortly after waking. Consuming caffeine during this peak can lead to increased tolerance and reduce the drink's stimulating effects. By waiting a little while, coffee drinkers can better enhance focus and productivity when they finally do indulge in that first cup.

As coffee remains one of Europe’s favorite beverages, with a strong reliance on its caffeine content, understanding the science behind the timing of consumption could lead to better health outcomes. The differing opinions among nutrition experts underscore the need for individuals to assess their personal habits and optimize coffee drinking for maximum benefit, rather than sticking to habitual practices that may not be advantageous.
