Fat Diets

Previous studies have suggested that high-fat diets adversely affect bone development. However, these studies included other dietary manipulations, including low calcium, folic acid, and fibre, and (or) high sucrose or cholesterol, and did not directly compare several common sources of dietary fat. Thus, the overall objective of this study was to investigate the effect of high-fat diets that differ in fat quality, representing diets high in saturated fatty acids (SFA), n-3 polyunsaturated fatty acids (PUFA), or n-6 PUFA, on femur bone mineral density (BMD), strength, and fatty acid composition. Forty-day-old male Sprague–Dawley rats were maintained for 65 days on high-fat diets (20% by weight), containing coconut oil (SFA; n = 10), flaxseed oil (n-3 PUFA; n = 10), or safflower oil (n-6 PUFA; n = 11). Chow-fed rats (n = 10), at 105 days of age, were included to represent animals on a control diet. Rats fed high-fat diets had higher body weights than the chow-fed rats (p < 0.001). Among all high-fat groups, there were no differences in femur BMD (p > 0.05) or biomechanical strength properties (p > 0.05). Femurs of groups fed either the high n-3 or high n-6 PUFA diets were stronger (as measured by peak load) than those of the chow-fed group, after adjustment for significant differences in body weight (p = 0.001). As expected, the femur fatty acid profile reflected the fatty acid composition of the diet consumed. These results suggest that high-fat diets, containing high levels of PUFA in the form of flaxseed or safflower oil, have a positive effect on bone strength when fed to male rats 6 to 15 weeks of age.

Acid Status

Essential fatty acids (EFA) have proved to be important for normal bone mineral density (BMD) and bone growth in animal studies. Patients with cystic fibrosis often have low serum EFA levels, and low BMD has also been reported in patients with normal anthropometry. The aim of the present study was to analyse if BMD during a 2-year period was related to fatty acid status in patients with cystic fibrosis. Fifty-four patients, aged 6–33 years, were studied prospectively. BMD was measured with dual X-ray absorptiometry, and fatty acid concentrations in serum phospholipids were determined with capillary GLC. The cystic fibrosis patients showed low linoleic acid concentration and a high arachidonic acid (AA):DHA ratio in serum. The high eicosatrienoic acid:AA ratio, an indicator of EFA deficiency, increased further over 2 years, as did the total concentration of saturated fatty acids. In the adults there were no significant changes in fatty acids during the study. In the children, positive correlations were found between palmitic acid and bone mineral content in the lumbar spine and femoral neck. The lumbar spine BMDZscore correlated negatively with the AA:DHA ratio. No correlation was seen in adults except for a positive correlation between EFA deficiency index and the areas of lumbar spine and femoral neck. The present results imply that fatty-acid status influenced BMD in cystic fibrosis children, but not in adults, indicating that fatty-acid status wouldbe important for bone growth.

Dietary polyunsaturated fatty acid (PUFA) incorporation into bone may alter its metabolism through changes in the fatty acid composition of membrane phospholipids. Alteration of the membrane phospholipid fatty acid composition may influence bone cell signalling and, potentially, bone mineralization. The objective of this study was to use the fat-1 mouse, a transgenic model that synthesizes n-3 from n-6 PUFA, to determine if the fat-1 gene modulates the fatty acid composition of femoral and vertebral phospholipids, and if so, whether the fatty acid levels would correlate with bone mineral density (BMD) at both skeletal sites. Male and female wild-type and fat-1 mice were fed an AIN93-G diet, containing 10% safflower oil, from weaning to 12 weeks of age. The fatty acid composition of femoral and vertebral phospholipids was measured by gas liquid chromatography. At 12 weeks of age, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine fractions in the vertebrae of fat-1 mice had a significantly lower n-6/n-3 ratio than wild-type mice (p < 0.05). In fat-1 femurs, these fractions, along with phosphatidylinositol, had a lower n-6/n-3 ratio than wild-type mice (p < 0.001). Docosahexaenoic acid (DHA) was positively correlated with BMD in all fractions in the vertebrae, and in phosphatidylinositol and phosphatidylserine in the femur (p < 0.05). Overall, the fat-1 gene resulted in changes in the fatty acid composition of both femoral and vertebral phospholipids. Significant correlations between DHA and BMD may indicate a positive effect on bone mineralization.
