A recent prospective study among Swedish women suggested an inverse association of dietary magnesium intake with incidence of colorectal cancer. The authors assessed this association in a cohort of 35,196 Iowa women initially free of cancer and aged 55-69 years in 1986. Intakes of magnesium and other nutrients were assessed by food frequency questionnaire at baseline. Over 17 years of follow-up...

PURPOSE This study aimed to compare strategies for assessing nutritional adequacy in the dietary intake of elite female athletes. METHODS Dietary intake was assessed using an adapted food-frequency questionnaire in 72 elite female athletes from a variety of sports. Nutritional adequacy was evaluated and compared using mean intake; the proportion of participants with intakes below Australian n...

Observational studies have shown that body mass indexes of vegetarians are lower than those of nonvegetarians and that caloric intake of vegetarians is typically lower than that of nonvegetarians, suggesting that a vegetarian diet could be an approach for weight management. However, vegetarians may be at risk of inadequate intakes of certain vitamins and minerals. Population-based studies indic...

Introduction: Studies indicate that 17.9% 60% of adults in Germany and Europe regularly use food supplements. Some reports suggest that their use might be responsible for excessive nutrient intake. The purpose of this survey was to examine the quantitative mineral intakes from food supplements: whether the tolerable upper intake levels (ULs) with supplements alone, or in combination with food w...

Magnesium (Mg) supplementation remarkably improves the digestibility of feed. In cows and sows, it has improved the reproduction and shortened the service period. In broilers it increased weight gain, and it has increased egg production of laying hens. In addition, increasing Mg intake benefits the quality of breeding eggs and improves hatching yield. However, increasing Mg intake has not alter...

Magnesium is the fourth most abundant cation in the body and plays an important physiological role in many of its functions. Magnesium balance is maintained by renal regulation of magnesium reabsorption. The exact mechanism of the renal regulation is not fully understood. Magnesium deficiency is a common problem in hospital patients, with a prevalence of about 10%. There are no readily availabl...

OBJECTIVE To examine the cross-sectional associations between dietary magnesium (Mg) intake and hyperuricemia (HU). METHODS 5168 subjects were included in this study. Dietary intake was assessed using a validated semi-quantitative food frequency questionnaire. Hyperuricemia (HU) was defined as uric acid ≥ 416 μmol/L for male population and ≥ 360 μmol/L for female. A multivariable logistic ana...

T HREE experiments were conducted with eight gestating Angus cows to study the effects of feeding different magnesium levels at 145,200 and 255 days gestation. Each trial consisted of a S-day adjustment period and a 10-day experimental period. The average daily magnesium intake for the cows fed the basal ration was 3.4 grams. Supplemental magnesium was added at levels of 0, 4.1, 8.2 and 16.4 g ...
