Nutrition has a greater impact on bone strength than exercise

One question that scientists and fitness experts alike would love to answer is whether exercise or nutrition has a bigger positive impact on bone strength.

University of Michigan researchers looked at mineral supplementation and exercise in mice, and found surprising results—nutrition has a greater impact on bone mass and strength than exercise. Further, even after the exercise training stopped, the mice retained bone strength gains as long as they ate a mineral-supplemented diet.

“The longer-term mineral-supplemented diet leads to not only increases in bone mass and strength, but the ability to maintain those increases even after detraining,” said David Kohn, a U-M professor in the schools of dentistry and engineering. “This was done in mice, but if you think about the progression to humans, diet is easier for someone to carry on as they get older and stop exercising, rather than the continuation of exercise itself.”
