There’s a lot of observational evidence that suggests that saturated fats impair calcium absorption in the gut, and thus increase your risk of osteoporosis. But such statements are as misleading as saying that you have to drink milk (or consume dairy) to maintain healthy bones.  While some studies have linked saturated fats to reduced calcium absorption, others have shown the opposite effect.  A review on the issue of dietary fat and calcium absorption published in the Royal Society of Chemistry clearly stated that, “Nevertheless, studies of dietary fat on passive Ca absorption are limited, and effects of HFD on CaB remain unknown.” In other words, there is no credible scientific evidence to suggest that the type of fatty acids humans have consumed for millions of years adversely affects bone health.  What causes weak bones is nutritional deficiency due to poor dietary habits. And in particular, a diet that lacks sufficient amounts of vitamin D3 and vitamin K2. I recently had a bone density scan done (see the image above) and it came back with a Z-score of 3.6, which is over 99% higher than the general population. So evidently, my evolutionarily consistent (high) intake of saturated fat doesn’t impact my body’s ability to absorb calcium in any way.
