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...

The Effect of Lactulose on the Composition of the Intestinal Microbiota and Short-chain Fatty Acid Production in Human Volunteers and a Computer-controlled Model of the Proximal Large Intestine

The objective of this study was to compare the in vivo effect of lactulose on faecal parameters with the effect in a dynamic, computer-controlled in vitro model of the proximal large intestine (TIM-2). Faecal samples from 10 human volunteers collected before (non-adapted) and after 1 week of treatment (10 g/day) with lactulose (lactulose-adapted...

Transgalactooligosaccharides stimulate calcium absorption in postmenopausal women

The aim of this study was to investigate whether a product rich in transgalactooligosaccharides (TOS, Elix'or) stimulates true Ca absorption in postmenopausal women. The study was a double-blind, randomized crossover study, consisting of two 9-d treatment periods separated by a 19-d washout period. During the treatment periods, 12 subjects drank...

Role of the non-digestible carbohydrate lactulose in the absorption of calcium

The current trends in healthy eating will increase levels of bulk- forming material in the diet, such as dietary fibre and other plant foods. Depending on the complex forming of such material the availability of absorbable calcium and other minerals may be impaired. It seems that non- digestible carbohydrates can inverse this effect. Major...

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...

Functional food properties of non-digestible oligosaccharides: a consensus report from the ENDO project (DGXII AIRII-CT94-1095)

This paper results from the final phase of the ENDO project (DGXII AIRII-CT94-1095), a European Commission-funded project on non-digestible oligosaccharides (NDO). All participants in the programme met to perform a consensus exercise on the possible functional food properties of NDO. Topics studied during the project (including a workshop on...

Bioavailability of calcium and magnesium

Chemicals/CAS: Calcium, 7440-70-2; Magnesium, 7439-95-4

Bioavailability of calcium of fresh cheeses, enteral food and mineral water. A study with stable calcium isotopes in young adult women

True fractional Ca absorption from six foods was measured in twelve normal healthy women, aged 20-29 years. The tested foods were commercially available fresh cheese, fresh cheese prepared by new technology and rich in Ca, similar cheese with added Fe, enteral food, mineral water alone and combined with a spaghetti meal. The aim of the study was...
