The effects of sugar-beet fibre supplementation for five weeks on zinc, iron and copper status in human subjects

Article Abstract:

Complex carbohydrates may reduce bioavailability of essential minerals by impairing intestinal absorption. A study was conducted to determine the effects of a fibre diet on zinc, iron and copper values in human subjects. Ten males were subjected to normal habitual dietary intake for 2 weeks followed by sugar-beet fiber supplementation for five weeks. The sugar-beet diet was then discontinued for four weeks. Measurements for zinc, iron and copper were conducted at one, two, seven and eleven weeks. Results show that sugar-beet consumption does not affect zinc, iron and copper status in the body.

Dietary fibre intakes in Europe : overview and summary of European research activities, conducted by members of the Management Committee of COST 92

Article Abstract:

The Management Committee of COST 92 appointed delegates for different European countries to collect data of fiber intakes, data from food balance sheets and individual fiber intakes. The data received exhibit that 50% of dietary fiber is obtained from cereals, 31% from vegetables, 16% from fruit and 3% from other sources. These data suggest the researchers to make a detailed study of European foods for fiber and formation of European-wide food tables.

Bioavailability of micronutrients in a fibre-rich diet, especially related to minerals

Article Abstract:

The influence of dietary fiber on the bioavailability of minerals is determined by in vitro analysis and experimenting on humans and animals. Mineral absorption or metabolism is not controlled by dietary fiber. Inadequacy of zinc and iron are identified when fiber- and phytate-rich diets are used. The natural high-fiber diet contains more minerals than a low-fiber diet.
