Vegetables, fruits, and grains are a major source of vital nutrients, but centuries of intensive agriculture have depleted our soils to historic lows. As a result, the broccoli you consume today may have less than half the vitamins and minerals that the equivalent serving would have contained a hundred years ago.
This is a matter of serious concern, since poor nutrition has been linked to myriad health problems including cancer, heart disease, obesity, high blood pressure, and diabetes. For optimum health we must increase the nutrient density of our foods to the levels enjoyed by previous generations.
To grow produce of the highest nutritional quality the essential minerals lacking in our soil must be replaced, but this re-mineralization calls for far more attention to detail than the simple addition of composted manure or NPK fertilizers.
