In the present double-blind, randomised, parallel intervention study, the effects of the intake of galacto-oligosaccharides (GOS) on the gut microbiota of twelve healthy adult subjects (aged 18-45 years with a normal BMI (18-25 kg/m2)) receiving amoxicillin (AMX) treatment were determined. All the subjects were treated with AMX (375 mg; three...

Lactose maldigestion and intolerance affect a large part of the world population. The underlying factors of lactose intolerance are not fully understood. In this review, the role of colonic metabolism is discussed, i.e. fermentation of lactose by the colonic microbiota, colonic processing of the fermentation metabolites and how these processes...

Background: Betaine (trimethylglycine) lowers plasma homocysteine, a possible risk factor for cardiovascular disease. However, studies in renal patients and in obese individuals who are on a weight-loss diet suggest that betaine supplementation raises blood cholesterol; data in healthy individuals are lacking. Such an effect on cholesterol would...

The effects of excessive non-toxic dietary Vitamin D3 supplementation on Ca homeostasis with specific effects on endochondral ossification and skeletal remodeling were investigated in a group of growing Great Dane dogs supplemented with cholecalciferol (Vitamin D3; HVitD) versus a control group (CVitD) (1350 μg versus 11.4 μg Vitamin D3 per...

Research on the bone effects of natural phyto-oestrogens after menopause is at a relatively early stage. Published studies are few, difficult to compare and often inconclusive, due in part to design weaknesses. Currently, many questions remain to be answered including to what extent a safe daily intake may prevent postmenopausal bone loss. These...

The prevalence of the severe disease spina bifida is decreasing, but the present rate is still unacceptably high. Only one-third of women planning motherhood use the recommended folic acid, although compliance is increasing. Campaigns for the use of folic acid by these women should be intensified. This method, however, cannot completely prevent...

A high dietary intake of antioxidants ascorbic acid, tocopherol and beta-carotene and 1 or 2 servings of fish per week is associated with a lower risk of coronary heart diseases, but the 'evidence' for a preventive effect still has not been produced. A raised homocysteine level can be lowered with folate, possibly in combination with pyridoxine...

In spite of an on average adequate dietary nutrient intake and status in most European countries, for some micronutrients (e.g. folate, vitamin D, B2, B6, B12 (in elderly), iron and iodine) subgroups have been identified which may be at risk and may benefit from a higher intake, especially elderly and (pregnant) women. In this paper the...

Previously performed short-term (4-month) studies demonstrated that vitamins C and E, β-carotene and selenium modulate growth of early putative preneoplastic acinar lesions induced in rat pancreas by azaserine. The present paper summarizes the results of long-term studies performed with azaserine-treated rats maintained on diets high in either β...

-Consumers increasingly use vitamin supplements. Also, since June 1996, foodstuffs enriched with vitamins are available on the Dutch market. -These sources of extra vitamins may be useful for groups at risk for marginal vitamin deficiencies. -These risk groups include the chronically ill (e.g. diabetics), people using medicaments, older people...

Surprisingly, neither the precise pharmacological effect nor the toxicological profile is usually established for food components. Carotenoids are no exception in this regard. Only limited insight into the pharmacology and toxicology of carotenoids exists. It is known that the antioxidant action of carotenoids is determined by 1. electron...

1. An earlier study by our group revealed that the viscosity of faeces from patients with Crohn's disease is significantly lower than that of healthy subjects. This is due to low concentrations of a high-molecular-mass carbohydrate, probably of bacterial origin. The cause of this phenomenon might be the impaired barrier function of the gut...

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...

1. A study with growing chicks investigated the effects of an inclusion of an endo-xylanase preparation (LYXASAN®) to a wheat- and rye-based diet on performance and nutrient digestibility in relation to the fat source. 2. The basal diet contained 500 g wheat and 100 g rye/kg of diet. The basal diet was supplemented with either 65 g soya oil/kg...

1. Two growth trials were performed to measure the effects of dietary methionine and cystine (SAA) on growth rate, food conversion efficiency and breast meat deposition in male broilers. 2. In experiment 1, broilers were grown on 6 experimental diets covering a range from 6.9 to 9.6 g SAA/kg. The diets were fed from 15 to 33 d of age. Similarly,...
