Dietary magnesium supplementation prior to slaughter has been reported to have a positive effect on meat quality,192 198 which can be explained by the ability of magnesium to counteract the effects of catecholamine in stress situations.199 200 Moesgaard et al.201 investigated how dietary... 

Magnesium deficiency, usually the result of decreased absorption or excessive excretion, results in neuromuscular weakness and ultimately convulsions. Dietary deficiency in catde is known as the grass staggers. Magnesium toxicity from impaired excretion or excessive consumption of antacids results in vomiting, hypertension, and central nervous systems effects. Inhalation of magnesium oxide from welding can cause metal fume fever similar to that from zinc.

The many diverse components of milk have demonstrable effects on human health. Perhaps, the most commonly associated component of dairy food is that of dietary calcium. Dairy products provide the most significant contribution to dietary calcium intake in the modem Western diet. It has been estimated that dairy products contribute to >72% of dietary calcium in the United States (Huth et al., 2006). Calcium is an important mineral for maintenance of optimal bone health (Bonjour et al., 2009) and is an integral component of key metabolic pathways relating to, for example, muscle contraction both in skeletal and smooth muscle (Cheng and Lederer, 2008). Further, dairy products contribute other essential nutrients in the diet, such as proteins, phosphorus, potassium, zinc, magnesium, selenium, folate, riboflavin, vitamin B12, and vitamin A (Haug et al., 2007 Huth et al., 2006). Low-fat milk alternatives are fortified with vitamin A and vitamin D which is added to milk and fermented milk in many countries making it an important source for vitamin D (Huth et al., 2006). 

Cellulose. Fiber components differ in their ability to bind to bile (41), the primary route of excretion of manganese (9). Cellulose, the most abundant natural fiber, has been studied for its potential effects on bile and lipid metabolism (42). It is naturally present in high fiber diets and is also commonly added to many commercially-produced food products. Previous studies have shown cellulose to decrease intestinal uptake of a variety of minerals, including zinc, phosphorus, calcium, magnesium, and iron (32,43,44). In many cases, however, the effect of cellulose has not been considered to be anti-nutritional (32). It has been generally believed that cellulose has a lower binding affinity for minerals than other constituents of dietary fiber (33,45). 

In a separate experiment with zinc supplied at 9 ppm in all diets, the effect of increasing dietary calcium in calcium or magnesium precipitated tofu or egg white diets on weight gain and tibia zinc accumulation was tested. From Table IV it can be noted that the performance of tofu-fed rats relative to zinc carbonate-fed rats was quite similar at 0.4% total dietary calcium, but was reduced as dietary calcium was increased to 0.7% and to 1.2%. These results suggest that a poorly available calcium-zinc-phytate complex not present in the soy curd can form in the gastrointestinal tract when sufficient calcium is added to the diet.

These studies indicate an intimate relation between the magnesium level of the diet and the pyridoxine requirement. It is suggested (A6) that, insofar as growth and urinary excretion of citrates, oxalates, and xanthurenic acid are concerned, high levels of magnesium appear to have a sparing effect on very low dietary levels of pyridoxine. 

Magnesium supplements may reduce hypertension in some persons. The issue of magnesium and the control of blood pressure has been difficult to establish conclusively. One study involving people with moderate hypertension revealed that daily doses of 20 mmol (485 mg) Mg could produce a decline in blood pressure, where at least three continuous months of supplementation were required for the effect (Witteman ( f a ., 1994). The 20-mmol supplement contained about double the usual dietary intake from food. Magnesium sulfate is commonly used as a drug...

Magnesium deficiency is relatively common in the United States. In many cases, it exists because of inadequate dietary intake. In other cases, it occurs as a side effect of some relatively common diseases, and a significant number of prescription medications tend to block its assimilation.
