The Claim

An increase of 5% in daily energy intake from carbohydrates is associated with a reduction in bone mineral density at the total hip and femoral neck in both men and women over a six-year period.

In plain English

Over six years, people who get 5% more of their daily calories from carbohydrates have lower bone mineral density in the hip and femoral neck compared to those who do not.

See the scientific wording

An increase of 5% in daily energy intake from carbohydrates is associated with a reduction in bone mineral density at the total hip and femoral neck in both men and women over a six-year period, suggesting that higher carbohydrate consumption may contribute to bone density loss in middle-aged adults.

Why this might work

When more carbohydrates are eaten, blood sugar rises quickly, causing the body to release too much insulin. This excess insulin tells the kidneys to dump more calcium into the urine and stops bone-building cells from working properly. Over time, this leads to weaker bones in the hip and thigh area.

  1. Study: Associations between Macronutrients Intake and Bone Mineral Density: A Longitudinal Analysis of the Health Workers Cohort Study Participants

    When people eat more carbs instead of protein or fat, their hip and thigh bones tend to get a little weaker over time — and this was seen in both men and women. Eating more protein or fat instead of carbs helped keep bones stronger.
