You could eat more string beans — except you might not want to, because they wouldn’t be as flavorful as in the past. So you could eat more of other vegetables, but it’s likely other vegetables wouldn’t have as much calcium or flavor as they used to, either. And it’s not just calcium: Preliminary research shows that many vegetables have lost significant amounts of nutritional value.

Davis believes that the primary reason f... Read more
