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.
