Diseases We Have That Our Ancestors Didn’t
Diseases We Have That Our Ancestors Didn’t by: Susan Patterson – Off the Grid News
We have been blessed with some amazing advances in modern technology which has allowed us comfort that was not possible a mere 100 years or so ago. But despite these advances, we suffer from severe chronic and degenerative diseases that were unknown to our recent ancestors.
We are a sick nation, overburdened by conditions such as diabetes, cancer, obesity, heart disease and allergies. Our healthcare system expense hit $3.8 trillion in 2014 — and is still on the rise. Yet we remain 37th out of 190 countries in the effectiveness of our healthcare system. We are plagued with disease, yet we have access to many technological advances that other countries will never be able to imagine, let alone realize.
According to Daniel Lieberman, a professor of Biological Sciences at Harvard University:
The fundamental answer to why so many humans are now getting sick from previously rare illnesses is that many of the body’s features were adaptive in the environments for which we evolved but have become maladaptive in the modern environments we have now created.
Spike In Diseases
This would explain why we have seen such a major spike in degenerative diseases such a Type 2 diabetes, and heart disease and Crohn’s disease. Allergies are more prevalent. Since the industrial revolution, the production and consumption of processed and fast food has skyrocketed, along with a sedentary lifestyle.
It is no longer the norm to grow our own food. Instead, we prefer our drive-through lunches and quick microwaveable dinners. The human body was not created to metabolize high volumes of vegetable oil and sugar — the main ingredients found in our industrial food supply. In addition, we were also not built to live such sedentary lives. Yes, things are very different than they once were.
In 1900, pneumonia was the leading cause of death in America and the life expectancy was only 47. In the early part of the 20th century, doctors were busy treating infectious diseases and inventing drugs to cure pneumonia and tuberculosis. With these advances, people lived longer and – thanks to poor lifestyle choices — began to develop coronary heart disease at startling rates. By the 1930s, heart disease became the leading cause of death.
