Do Dairy Minerals Have a Positive Effect on Bone Health?

Abstract

This review aims to examine the relationship between the consumption of dairy products, mineral absorption, and bone health, and critically evaluates the methods that have been used to investigate this relationship. As people live longer and have lives that are more active in modern societies, bone health is of concern due to the possibility for the increasing incidence of bone disorders, such as osteoporosis. It has been suggested that dairy products can play a key role in bone health due to their high levels of minerals. Whether the positive effect of dairy consumption on bone health is due solely to the concentration of minerals, the action of vitamins, proteins, and lipids present in dairy products, and complex interactions between different milk components remains to be determined. Assessment of how dairy products affect bone health is complex, with apparent contradictory conclusions being reported in the literature. To gain a better understanding of the effects that dairy products have on bone health, this review presents an evaluation of a combination of data obtained using a variety of methods. From those data, we surmise that the preferable approach to investigate the effects of milk on bone health is to obtain data from human, animal, and cell line testing. A combined approach will enable various aspects to be identified, including mechanisms and the assessment of holistic effects, which will enable the effects in the human situation to be ascertained.

Energy‐dispersive X‐ray fluorescence spectrometry as a tool for the rapid determination of the five major minerals (Na, Mg, K, P and Ca) in skim milk powder

“…The EM approach in this scenario was not applicable due to the inherent lack of range in commercial dairy samples as discussed by Burrow et al . (). Results collected from each method of analysis were compared using Sigmaplot (version 14.0; Systat Software Inc.) to carry out Bland–Altman analysis, comparing the differences between the two methods of analysis rather than their relationship as discussed by Giavarina ().…”

“…These factors are of particular concern to the infant formula and follow‐on formula industries as essential minerals such as sodium (Na), magnesium (Mg), potassium (K), phosphorus (P) and calcium (Ca) must comply with specified recommended daily intake (RDA) or minimum values (Codex Standard 72.1981). Table shows the typical reported ranges for whole bovine milk (Burrow et al …”

“…The composition of IMF supports the nutrition of many newborns at a vital stage in their development and must abide by established guidelines (Koletzko et al .,; Thompkinson and Kharb ). The importance of elemental contents and their ratios in dietary regimens is well established (Burrow et al …”

The Distribution of Essential, Trace, and Nonessential Minerals in Weanling Male Rats Fed Sheep or Cow Milk

“…Increased mineral absorption has been observed due to the consumption of milks independent of the high mineral concentration present . Cow, buffalo, and goat milks have potentially beneficial effects on Ca absorption .…”

“…[9] However, little is known about the nonradioactive (stable) isotopes of cations, such as rubidium (Rb) and cesium (Cs), and how they interact in the food chain. [10,11] Increased mineral absorption has been observed due to the consumption of milks [12,13] independent of the high mineral concentration present. [12] Cow, buffalo, and goat milks have potentially beneficial effects on Ca absorption.…”
