When we buy cheap food, its value is often measured by yield rather than nutritional content. Research has shown that since the 1930s, food grown this way has lost around 40% of its key minerals; other nutrients have probably suffered, too.

In correlation with the loss of nutrients, the burden of disease has shifted from infectious cases of TB, typhoid and cholera to more prevalent, degenerative diseases. Cancer, obesity, arthritis, osteoporosis, heart disease, mental illness and infertility are all increasing. The problem is being compounded, as poor nutrition, over generations, weakens the genetic code. This means our children inherit their parents’ weaknesses and the onset of disease occurs at an ever earlier age. If this continues our ability to reproduce successfully will be seriously eroded.
