Life on Earth is very fragile. External factors of all kinds constantly threaten the survival of all species, including us. But internal factors in each living organism also add up. Diseases and ailments that attack almost imperceptibly from within.
Humans, despite our physical limitations, managed to develop complex intelligence as we acquired knowledge about the functioning of our body and our environment. Then, little by little we were creating the conditions to shovel the hostile conditions of nature and thus increase our life expectancy.
Modern medicine after thousands of years of evolution is almost a miracle that allows people to recover from previously deadly diseases and to lead full lives.
However, as new diseases appear and some old ones remain, evolutionary medicine has set itself the task of investigating the past of our species and understanding the diseases that afflicted our ancestors in order to better understand the ills that affect us today.
Among the categories identified by the studies, firstly, a type of disease produced by the important change in the dynamics of human life produced by the industrial revolution is recognized. The mechanization of our environment has reduced our caloric needs, yet our diet is still full of high-calorie foods.
Today’s food production is high in sugar, low in fiber, and high in refining. This, combined with lower levels of physical activity compared to our ancestors, has generated high levels of obesity and diabetes in the population.
Scientists also claim that in view of the great genetic diversity of the human species, defining a diet as “normal” or applicable to all people equally is a big mistake. Experts suggest that each person’s diet should consider their particular genetic characteristics in combination with their energy needs and their cultural background.
We hope that evolutionary medicine research will continue in order to understand and prevent the diseases that most affect humanity.
