Eat more blueberries to strengthen your bones

Eating more blueberries can make your bones stronger and healthier, according to a new study published in the Journal of bone and mineral research A new study funded by the U.S Department of agriculture, by Dr Chen Jinran and colleagues from the Kansas children's nutrition center, found that compounds in blueberries play an important role in the strong and healthy bone development of experimental mice If this research is confirmed by human experiments, it is undoubtedly of great significance to solve the problems of human bone development and osteoporosis The polyphenol complex, a key coloring substance in blueberries that makes the fruit appear blue, purple and red, is crucial to the healthy and strong bone development process of the mice, the researchers said In animal experiments, the bone density of rats fed with 10% lyophilized blueberry powder was significantly higher than that of rats without blueberry food When the researchers added the laboratory cultured bone forming cell "Gegenbauer cells" to the plasma of the two groups of mice, the results showed that the cells developed into mature and functional bone cells faster in the plasma of the blueberry group of experimental mice The content of phenolic acid (polyphenol extract) in the plasma of blueberry group was higher The results show that phenolic acids play an important role in the process of bone formation It was also found that the process of phenolic acids stimulating bone growth may involve two genes TCF and lef and protein β - Catenin The next step will be human trials to determine whether such substances have the same or similar effects on human bone growth, Chen said.
