Blueberries may be the ultimate super fruit, especially for women over 40, who want to protect their bone density.
The presence of polyphenols and anthocyanins in blueberries can help to promote bone strength and even offer some protection again the onset of osteoporosis. The Journal of Bone and Mineral Research, published a research postulating that the polyphenol content in blueberries is most likely responsible for the increased bone strength shown in laboratory study rats.
Evidence is accumulating that blueberries can activate cells that actually help build and regenerate bones. Besides they posses anti-inflammatory property & have ability to kill bacteria and stimulate normal growth. Being rich in antioxidants they can scavenge and neutralize oxygen radicals. It appears from the rat studies that the polyphenols are somehow able to stimulate the bone cells to make more bone which is healthy. The medical research community has carried out numerous studies into the relationship between blueberries and improved bone strength and densite for people with osteoporosis.
How many blueberries to consume for bone growth?
There is no universal recommendation on how many blueberries one needs to consume to enhance bone growth, but experts suggest that at least one cup worth of blueberries everyday will be needed to strengthen bone.
How it Works?
The National Osteoporosis Foundation states that adults over 50 should consume 1,200 milligrams of calcium and 1,000 international units of vitamin D every day in order to promote strong bones.
Without these nutrients, how do blueberries improve bone density?
The study authors from the University of Arkansas for Medical Sciences, say that the berry’s polyphenols likely activate two genes and a protein that are involved in a critical bone-building molecular pathway.
The genes, called TCF and LEF, promote the expression of the protein, beta-catechin. This molecule in turn encourages osteoblasts to mature faster and produce more bone mineral.

Scientists concluded that blueberry consumption may improve human bone density or even lower the risk of osteoporosis.
