Since sweet potatoes, which also furnish vitamin A, are a common food in the popular diets of Texas and are so generally grown over the state, the purpose of this study is (1) to ascertain the amount of vitamin C in eight of the varieties most commonly grown and (2) to determine the effect of the three most popular methods of cooking (boiling, baking, and candying) on the vitamin C content of these varieties of sweet potatoes.

The purpose of the present study is to determine the effect of cooking on the vitamin A value of "Vita-Yam" candy and cookies.

The purpose of the present study was to compare the amounts of vitamin A in sweet potato flour with that of carrot flour and dehydrated carrots by using the biological assay method.

This study attempted to determine the amount of time spent on nonpaid daily activities by retired people and to identify management problems encountered while performing daily activities. Time use data were collected by daily records completed by the subjects. Variables examined were age, sex, health, education, level of income, and living arrangements. Age and sex were related to total time spent on household activities and family care. Those in the oldest age group spent the least amount of time on household activities and family care and men spent less time than women on these activities. Health, living arrangements, income, and transportation were identified as management problems. These problems were not incapacitating and most elderly were able to live independently at home.
