Our brains are shrinking faster than expected, and the reason may be closer than we think.
A recent scientific study set off alarm bells in the international community by revealing that The human brain is shrinking in sizeThis phenomenon, which may sound alarming, raises a series of questions about the evolution and future of human beings.
While brain shrinkage is nothing new, having been observed for thousands of years, the new report delves into the current causes of this phenomenon and suggests that modern factorssuch as lifestyle and dietary changes, could be accelerating this process.

Why human brains are getting smaller
Research suggests that a combination of evolutionary and social changes could be behind this phenomenon. Modern humans no longer faces the same challenges than their ancestors, which reduced the need to maintain such a large and energy-intensive brain. Added to this are technological and social improvements that, in a sense, reduced our reliance on complex cognitive skills, favoring brain shrinkage.
Another hypothesis suggests that our diet, with the Mass consumption of ultra-processed foods and less variety of nutrients, could be affecting the development and maintenance of the brain. Scientists continue to investigate, but the first results suggest that the brains of the future could be smaller than those of today, and that would bring drastic changes in our species.
