Short-chain fructo-oligosaccharides improve magnesium absorption in adolescent girls with a low calcium intake

Consumption of fructo-oligosaccharides (FOS) has been shown to improve mineral absorption in the short term, but no long-term effects were studied in girls with a low calcium intake. Therefore, we hypothesized that short- and long-term consumption of short-chain FOS (sc-FOS) improves calcium and magnesium absorption in girls with a low habitual...

Voeding als wapen tegen osteoporose: het belang van voedsel als bron van calcium en vitamine D

Chemicals/CAS: calcitriol, 32222-06-3, 32511-63-0, 66772-14-3; calcium, 7440-70-2; ergocalciferol, 50-14-6, 50809-47-7, 8042-78-2; parathyroid hormone, 12584-96-2, 68893-82-3, 9002-64-6

Lactulose stimulates calcium absorption in postmenopausal women

Animal studies have indicated that calcium absorption is increased by lactulose, a synthetic disaccharide. Therefore, the influence of lactulose on calcium absorption was measured in postmenopausal women who may benefit from the possible enhancing effect of lactulose on calcium absorption. Twelve postmenopausal women drank 100 ml of water...

Oligofructose stimulates calcium absorption in adolescents

Background: In rats, nondigestible oligosaccharides stimulate calcium absorption. Recently, this effect was also found in human subjects. Objective: The objective of the study was to investigate whether consumption of 15 g oligofructose/d stimulates calcium absorption in male adolescents. Design: Twelve healthy, male adolescents aged 14-16 y...

Vitamins and cancer

The prospect that high intake of certain vitamins may confer protection against cancer has drawn substantial attention during the last decades. This paper gives a concise update of the role of a number of promising vitamins in prevention of cancer. Vitamin A and its analogues have an important role in cellular processes related to carcinogenesis...

The rat incisor in toxicologic pathology

Microscopic examination of the incisors of rats and mice may reveal toxicologically significant changes. First, the incisor morphology reflects the nutritional status of the animal: fluctuations of mineral metabolism and vitamin availability are disclosed by the rodent incisors, because the incisors continue to grow during life. Similarly,...
