It´s well known that fruits and vegetables are good for your health. But did you know that a diet high in fruits and vegetables could also support good bone health?

New research from the University of Surrey has found that the potassium salts that are plentiful in fruits and vegetables play an important role in improving bone health. The scientists showed that these potassium salts (bicarbonate and citrate) reduce bone resorption, the process by which bone is broken down, thereby increasing their strength.

A high intake of potassium salts was found to significantly reduce the excretion of calcium and acid in urine. As a result, excess acid is neutralised and bone mineral is preserved, explained lead author Dr Helen Lambert from the University of Surrey.

The study contributes to our understanding of how we can improve the strength of our bones.

“Excess acid in the body, produced as a result of a typical Western diet high in animal and cereal protein, causes bones to weaken and fracture. Our study shows that these salts could prevent osteoporosis, as our results showed a decrease in bone resorption,” Dr Lambert added.

In healthy adults, bone resorption and bone formation occurs naturally, allowing bones to grow, heal and adapt. But in people with osteoporosis the balance is shifted so that more bone is broken down than is built up, leading to fragility and fractures, the University of Surrey said.

This research shows that eating more fruits and vegetables could be a way to help strengthen our bones and prevent osteoporosis.

The findings of the study have been published in the journal Osteoporosis International.
