Low-fat Dieting Does Not Reduce Calcium Intake in Women
Dunedin, New Zealand -- A study published in the American Journal of Clinical Nutrition (1997)indicated that women can be on low-fat diets without added risk of inadequate calcium intake.
Dairy products can contain significant amounts of fat calories and their intake could be limited by persons concerned with risk of heart disease. Dairy products, such as milk, also have high calcium content, and provide a major source of calcium which is necessary for healthy bones. Therefore, inadequate calcium intake in women on low-fat diets theoretically could increase their risk of developing the weakened bone of osteoporosis.
The study, published in the American Journal of Clinical Nutrition (1997), Jane Upritchard and associates at the University of Otago in New Zealand studied calcium intake of 247 women, aged 50-65 years, who were on a variety of diets. Their data showed that overall calcium intake was not reduced in those women who were low-fat dieting for reasons of weight or blood cholesterol reduction compared to non-dieters. The women on low-fat diets were able to obtain calcium in amounts equal to their non-dieting counterparts by selecting foods both high in calcium and low in fats, such as low fat milk.
However, another significant finding of the study
was a surprisingly low calcium intake overall for all groups of
women. The authors noted that "virtually all had an intake
below the 1500mg advised by the recent Hong Kong Consensus Conference
