摘要:

Vitamin B12 and folate status was determined in 50 male and 47 female free-living subjects (65-77 years) in winter and summer. The mean intake calculated from 3-day food records met the Canadian recommended intake (RNI) for both gender and season, however, probability analysis of dietary data revealed a number of subjects at risk of deficiency. Although the mean plasma levels were within the acceptable range for both vitamins, some 9 to 14% of individual subjects had folate plasma levels below normal. Fewer subjects had subnormal plasma vitamin B12 levels. Although mean values for dietary intake and plasma concentration of folate and vitamin B12 may indicate nutritional adequacy, a proportion of an older population may be at nutritional risk.

摘要:

This study evaluated reported dietary fiber and mineral intakes of 45 healthy adults, 60 years and over, using two sets of three-day dietary food records. The average age of the participants was 73 years, with an age range of 60 to 87 years. Mean reported dietary fiber intake was 18.3 g per day. Percentage of dietary fiber from different food sources was; breads and cereals 33%, vegetables 22%, fruits 21%, beans and legumes 7%, nuts and seeds 3%, combination foods 7% and others 7%. Significant positive correlations were observed between dietary fiber intake and copper, magnesium, selenium, potassium, iron and zinc intakes. Those participants with dietary fiber intakes of 20 g/day or more had significantly higher intakes of copper, magnesium, selenium, potassium and iron compared to those who had dietary fiber intakes less than 20 g/day, although mean kilocalorie intakes were not significantly different. Thus, increasing grain products, vegetables and fruits to increase dietary fiber intake, also may improve the mineral intakes of older adults.

摘要:

Nutrition has been implicated in the quality of life of older adults, beyond proving essential nutrients and calories. Recent concern about malnutrition has prompted a broader social-psychological approach to nutrition and aging research. The present investigation examined the relationship of self-actualization and social support to dietary intake. Data from 100 community-dwelling adults, ages 60-83 years, revealed significant and positive associations between the predictor variables and vitamin A, B vitamin complex, iron, and dietary fiber. Specifically, the personality trait of being internally motivated and the presence of support from family, friends and neighbors were found to positively influence dietary quality.
