One of the leading myths about osteoporosis is that it’s caused by a lack of calcium in the diet.
You have probably also heard that you need to strengthen your bones with exercise.
However, according to a new study in the Journal of Orthopaedic Surgery and Research, the #1 cause of osteoporosis lies elsewhere.
That cause is a group of common foods you are most definitely consuming.
The researchers obtained information about 10,521 people first collected in the National Health and Nutrition Examination Survey from 2005 to 2018. This information included dietary questionnaires and bone health measurements.
The researchers used a dietary inflammatory index to score the inflammatory potential of their subject’s diets.
This is a list of the effects of 45 food components/nutrients on inflammatory chemicals in the body.
They assessed bone health by measuring femoral neck bone mineral density (BMD) and bone mineral content (BMC) using dual-energy X-ray absorptiometry.
These were their findings.
-
1. Overall, the higher the dietary inflammatory index of the subjects’ diets was, the lower their BMD and BMC were.
2. This relationship between the dietary inflammatory index and BMD and BMC only held for subjects who were overweight or obese.
3. In underweight subjects, (strangely) inflammatory foods seemed to protect against BMD and BMC loss.
4. In normal-weight subjects, there was no relationship at all between inflammatory foods and BMD and BMC.
Therefore, pro-inflammatory foods can cause poor bone health, but only in people who are overweight or obese. This shows that both weight and inflammatory foods are harmful but that weight plays the deciding role.
