Retinol, alpha-tocopherol and carotenoids in diabetes

Article Abstract:

A study undertook to re-examine the serum levels of retinol, alpha-carotene, beta-carotene, alpha-tocopherol, serum and urine retinol binding protein (RBP) in subjects with diabetes mellitus. The results were compared with healthy controls to determine the links between these nutrients in patients with diabetes mellitus. The results suggest that patients with diabetes may have reduced levels of beta-carotene, and there is a negative link between beta-carotene and glycaemic control. Serum and urine RBP levels were indicated in patients with renal impairment and in diabetic patients.

Concentrations of tocopherols and carotenoids in maternal and cord blood plasma

Article Abstract:

Blood plasma gamma-tocopherol (TOH) concentrations are lower at birth than in later life, according to research into the relationships between levels of tocopherols, retinol and carotenoids in maternal and umbilical cord blood plasma. Cholesterol and triglyceride levels were found to be lower in cord plasma than in maternal plasma. There was a strong link between cord plasma TOHs and cholesterol and triglycerides. There was no connection between maternal and cord plasma x-TOH levels.

Plasma concentrations of carotenoid and antioxidant vitamins in Scottish males: influences of smoking

Article Abstract:

Carotenoid and vitamin C deficiency observed in smokers, due to various dietary strategies or because of enhanced metabolic turnover, are overcome by elevated consumption of carotenoid and vitamin C within the nutritional range. High intake of beta-carotene raises the probability of lung cancer in long-term smokers. Smokers have low percentages of alpha-carotene, beta-carotene and beta-cryptoxanthin and vitamin C in plasma.
