Effect of functional food ingredients on nutrient absorption and digestion

Abstract: Consumption of functional foods may provide health benefits by reducing risk of many chronic diseases and improve structure and function of the human body. However, in the addition to the positive effect of absorption and digestion of functional ingredients, the interaction between food constituents and bioactives present in functional foods may strongly affect the bioavailability of dietary macronutrients and micronutrients. Gelation of dietary fiber in intestines may decrease digestibility and absorption of fat and carbohydrates but also may affect absorption of calcium, magnesium, and iron. In contrast, inulin and fructooligosaccharides may increase absorption of calcium and magnesium. High consumption of polyphenolic compounds, including tannins, can reduce bioavailability of iron and copper which may be a causative factor of anemia. Tannins present in green tea or its extracts may adversely affect functions. Thiocyanates, present cruciferous vegetables, may decrease iodine availability to the thyroid gland and decrease synthesis of precursors of thyroid hormones. This chapter will address positive and negative effects associated with absorption and digestibility of bioactive compounds.

The Availability of Zinc, Cadmium and Iron from Different Grains Measured as Isotope Absorption and Mineral Accumulation in Rats

Abstract: The purpose of this study in rats was to determine if the absorption and accumulation of zinc, cadmium and iron differ amoung diets based on different grains and, if so, what differences among the grains might account for the differences in mineral absorption.

Sodium-calcium in young citrus: Ratio of sodium to calcium in the nutrient solution of sand cultures shown to affect mineral absorption and plant growth

Abstract: Not Available – First paragraph follows: Irrigation waters applied to citrus orchards vary considerably—in their sodium and calcium content—in different locations, so studies were made with pure silica sand cultures with nutrient solutions of similar nitrate content and ratios of sodium and calcium.

Performance and Oxidative Stress Biomarkers of West African Dwarf Goats Fed Diet Containing Incremental Sodium Humate

Abstract: Problems relating to reduced performance owing to mineral deficiencies in grazing animals and oxidative stress occasioned by changing weather condition can be addressed through strategic mineral supplementation and improving antioxidant capacity of the animals. A 97-day trial was designed to assess the performance and apparent nutrient digestibility of West African Dwarf (WAD) goats fed diets with incremental levels of sodium humate. Thirty (30) WAD bucks of ages between 10-15 months were used for this study. The bucks were randomly assigned to five dietary treatments containing 0, 5, 7.5, 10 and 12.5 g/kg diet of sodium humate laid out as completely randomized design. Data on weight changes, dry matter concentrate intake, feed conversion ratio (FCR), nutrient digestibility and rate of mineral absorption were obtained and statistically analysed using the generalized linear model (GLM) of Statistical Package for Social Sciences (SPSS) (version 23). Results revealed that sodium humate supplementation improved (p <0.05) weight gain, FCR, mineral (Zn, Cu, Mn and Na) absorption and nutrient (dry matter (DM), crude protein (CP), crude fibre (CF), ash, ether extracts (EE), neutral detergent fiber (NDF) and acid detergent fiber (ADF)) digestibility. Supplementation of sodium humate decreased concentrate intake (p <0.05). After 30 days of sodium humate supplementation, malondialdehyde (MDA) increased (p <0.05) at higher levels, glutathione peroxidase also increased up to the level of 7.5 g/kg diet sodium humate and then decreased in subsequent levels, with superoxide dismutase (SOD) observed to decrease (p <0.05). However, at 90 days of sodium humate supplementation, MDA, nitric oxide (NO) and bilirubin decreased (p <0.05) while albumin and uric acid increased (p <0.05).Conclusively, up to 12.5 g/kg diet supplementation of sodium humate sufficiently enhanced performance of WAD goats while also improving their antioxidant capacity.
