Higher Milk Consumption Is Associated with Reduced Risk of Hip Fractures

Higher Milk Consumption Is Associated with Reduced Risk of Hip Fractures

Bone density decreases with age, leading to an increased risk of hip fractures. Milk is considered helpful for maintaining bone health due to its high calcium, protein, and its fortification with vitamin D, and the 2015 Dietary Guidelines for Americans recommends that adults consume two to three cups of milk or equivalent dairy foods per day to protect aging bones.

Ancient Aurochs Genome Contains the DNA Blueprint for Modern Cattle

Ancient Aurochs Genome Contains the DNA Blueprint for Modern Cattle

A preserved specimen of aurochs bone was discovered deep beneath the Derbyshire Dales in the UK in the 1990s. Aurochs are an ancient cattle breed domesticated around 10,000 years ago somewhere around modern day Iran. In Europe, the last of these animals were still found on a Polish royal reserve as recently as the 17th century. Park et al., have now extracted enough DNA from the ancient bone specimen to sequence the aurochs genome. When they compared the aurochs sequence to the DNA of cattle breeds we know and use in domestic agriculture today, they found a surprisingly high level in common with British and Irish cattle.

Children Who Avoid Cow’s Milk May Fall Short of Vitamin D

Children Who Avoid Cow’s Milk May Fall Short of Vitamin D

Rickets and vitamin D deficiency do not sound like 21st century issues. Yet nearly 100 years since the connection between the two was first identified, the U.S., Canada, and numerous other countries are facing a potential epidemic of vitamin D deficiency among children (1). The reasons for the resurgence are much the same as they were in the past: limited sunlight exposure and poor dietary intake of this essential nutrient. Vitamin D-fortified milk helped bring an end to the rickets epidemic in the early 1900s, and it remains the best dietary source of vitamin D for children today. However, a growing number of children do not drink cow’s milk. A handful of studies have found that children who avoid cow’s milk due to allergy, intolerance, or dietary preference for alternative milk beverages are at a greater risk for vitamin D deficiency (2-4). When coupled with medical advice to avoid the sun, these findings could help explain the increasing prevalence of vitamin D deficiency in otherwise healthy children. While scurvy may have gone the way of the pirate, rickets is still a modern concern. Read More...

So far, the journal has published 45 rapid responses to this article compared with an average of 3 responses to other articles in the same issue. What’s all the fuss about? Read More...

Boning Up on Dairy and Skeletal Health

Boning Up on Dairy and Skeletal Health

For its weight, bone is the strongest material in nature. Developing and maintaining strong bones is heavily influenced by your genetic makeup, but nutritional and other environmental factors can make or break your chances of reaching your genetic potential. The role of calcium in supporting bone growth and preventing bone loss is well known, but overall, bone health depends on more than just calcium. Read More...

Prescriptions for Bovine Lactoferrin

Prescriptions for Bovine Lactoferrin

The anti-microbial milk protein lactoferrin appears to fight Crohn’s disease, necrotizing enterocolitis, diarrhea, cancer and osteoarthritis. As it also promotes bone growth it holds the promise of treating degenerative bone disease. This common protein may be just the prescription that the doctor orders. Read More...
