Although Sweetpotatoes have been rated* as one of the best

vegetables for overall nutrition, per capita consumption continues

to decline. In 1949 per capita consumption was 13.9 pounds; the

estimate for the year 2000 is 4.6 pounds/year.

Within the next few years nutrition educators will be moving from the “5 A Day” theme to “7 Fruits and Vegetables Per Day.” It would benefit the collective sweetpotato industry if a planned advocacy program were begun now. Three servings of sweetpotatoes per week would be a reasonable goal.



Sweetpotatoes have natural cancer-fighting nutrients.

• The “A.C.E.” vitamins which act as anti-oxidants during the initiation stage of cancer.

• Ten percent of the daily fiber to help protect against digestive system cancers.

• Very low fat – both cancer & heart-smart!



The nation’s nutrition would be enhanced -- naturally.

Per capita consumption would climb to over 30 pounds per year!

Creative and healthy value-added sweetpotato products will be needed.

A well-thought out advertising campaign needs to be developed.
