Clinical Nutrition (Edinburgh, Scotland)

BACKGROUND & AIMS: Adequate dietary intake of antioxidants is vital for the promotion of health, well being and longevity of the elderly. This study assessed the prevalence of vitamin A (retinol) and vitamin E (alpha-tocopherol) deficiency in a population of low-income South African elderly. METHODS: Serum vitamin A and vitamin E concentrations were determined in 235 persons aged 60-93 years in Sharpeville, South Africa. Dietary assessment was done using 24-h recall. Weight and height were measured to determine body mass index.

Dietary fat intake is extremely low in most communities with vitamin A deficiency. However, its role in vitamin A status of pregnant and lactating women is poorly understood. The aim of the study was to examine the effect of supplementing women with fat from mid-/late pregnancy until six months postpartum on their vitamin A status and that of their infants. Women recruited at 5-7 months of gestation were supplemented daily with 20 mL of soybean-oil (n = 248) until six months postpartum or received no supplement (n = 251).

Vitamin A deficiency continues to be an international public health problem with several important health consequences including blindness and overall increased rates of morbidity and mortality. To address this widespread issue, a series of strategies have been put into place from dietary diversification to supplementation and fortification programs. Retinyl palmitate has been used successfully for decades as a supplement as well as a way to fortify numerous foods, including vegetable oil, rice, monosodium glutamate, cereal flours and sugar.
