Changes in Nutritional Values

If I could learn to link posts within this blog you might know that I have been making some efforts to find out about changes in the nutritive values of our fruits and vegetables over recent decades. I am close to giving up those efforts.

I have found that recent nutritional values of many foods have been nicely and authoritatively laid out by Susan E. Gebhardt and Robin G. Thomas in Home and Garden Bulletin Number 72 of the Agricultural Research Service of the USDA. However, they make no comparisons, with past values.

I have also learned that David Haytowitz, a Vegetable Nutrition Data Specialist for USDA might know of such comparisons, But have not been able to contact him. Many of the people on government agencies are home on vacation.
