Humans gain peak bone mass in their 20s and then this starts to decline. Having strong bones is essential for moving around and for completing everyday tasks, hence why it is important to maintain bone mass and strength as you age.
People often associate physical exercise as the main means to building and maintaining strong bones. Weight bearing exercises such as jogging or hiking (you should always consider wearing protective footwear such as the best shoes for walking) are recommended as well as resistance exercises such as adding a set of adjustable dumbbells into your workouts.
However, a research team from the University of Michigan had a study published in the PLOS (opens in new tab) journal revealing that nutrition has a more significant impact on bone mass and strength than exercise does.
The study that was carried out on mice, investigated the effect of a long-term mineral-supplemented diet on preventing the loss of bone mass and strength with age. They specifically increased the intake of calcium and phosphorus.
As the study progressed, the researchers were surprised to also discover that when the exercise element of the testing stopped the mice still retained bone strength gains, as long as they were still consuming a mineral-supplemented diet.
David Kohn a professor at the University of Michigan said, "The data suggests the long-term consumption of the mineral-supplemented diet could be beneficial in preventing the loss of bone and strength with age, even if you don't do exercise training."
Kohn explained that despite the fact that the study was conducted on mice, this information is still applicable to humans.
"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," said Kohn.
He also highlights that this doesn't mean everyone should go out and buy calcium and phosphorus supplements. But it gives an indication that we can all look into our diet more when trying to protect our bodies as we age.
You can start by ensuring you are eating foods rich in calcium (milk, yoghurt and dark leafy green vegetables) and vitamin D (red meat, egg yolks and mushrooms). Getting enough protein is essential as it makes up nearly half of the volume of bone and approximately one-third of its mass.
Dietary proteins are essential for bone health but if you can't source enough of this in the foods you eat then using a best protein powder for women can help with this.
Despite nutrition playing a massive role in maintaining bone mass and strength, regular exercise is still very important to try and keep up with.
As mentioned earlier on, it can be in the form of a light run or by adding some resistance into training (such as using a best resistance band) but putting your body to work is an essential building block for maintaining good bone health.
