Supports Chapter 25: Deficiency diseases
New research suggests that body fat may have an impact on bone mineral density.
Results of a study by Kathryn Piehowski, RD, of Pennsylvania State University showed that bone mineral density in normal weight women was higher than in overweight women.
The report suggested that the reasons why fatter women should have a lower bone mineral density were unclear. Piehowski suggests that inflammation may well play a role, as high levels of body fat are associated with greater levels of inflammation, and some inflammatory mediators are known to promote bone loss.
Well, it might. But there may well be another reason. Fatter women tend to be those on calorie controlled, carbohydrate-based diets. These are inevitably low in fat and, as fat comes mainly with protein, low in protein as well. Although women are told that low bone density can be caused by eating a high-protein diet, in fact the opposite is true. The real reason for the low bone density in fatter women, therefore, could well be their reliance on a ‘healthy’ diet
