The health of many westerners has steadily worsened despite big advancements in medicine and healthcare. The rate of diabetes among 30–39 year-olds rose by 70% between 1990 and 1998 and since 1970 cancer rates have risen.
Even modern medicine with all its advancements hasn’t come up with a “magic pill.” Overconfidence in medicine to help us remain healthy doesn’t always seem reliable too because the medication can have severe side-effects.
A way better focus would be to prevent disease instead of waiting for it and then try to solve it. The biggest long-term health factor turns out to be nutrition.
Maintaining a healthy diet has shown to prevent and even reverse early stages of heart diseases.
