Long-term avoidance of milk in children results in poor bone health

Children who avoided drinking milk in early life have low dietary calcium intakes and poor bone health, including significantly smaller bones and a higher incidence of fractures. The study highlights the importance of increasing calcium intake in growing skeletons to mitigate these effects.

Not drinking cows' milk blamed for children's fractures

A recent study found that almost 50% of children between three to ten years old who avoided cow's milk for four months or more had suffered one or more fractures. The researchers discovered that these children often had low bone density and were short and overweight, suggesting a link between milk avoidance and poor bone health.

Study shows flavored milk gives kids more calcium but not fat & calories

A University of Vermont study found that children who consume flavored milk have higher calcium intakes than those who don't. Flavored milk helps boost overall calcium intake without impacting total added sugar consumption, reversing the trend towards soft drink and fruit drink consumption in children.

Calcification of breast blood vessels may predict stroke risk

Researchers discovered that calcification of breast blood vessels is associated with an increased risk of stroke. Women with diabetes, older age, and low educational background are at higher risk. Mammograms might one day be used to better determine a woman's cardiovascular risk.

A study of 42 women found that maternal folate status during extended lactation was sustained by supplementing with 1 mg folic acid per day. This supplementation helped maintain plasma and milk folate levels as well as hematocrit, but had no effect on unsupplemented women.

Possible Breast Carcinogen Found In Human Milk

Aromatic amines, used in industrial processes, have been detected in human milk, raising concerns about breast cancer risk and infant exposure. The study's findings suggest that breast ductal epithelial cells are also exposed to these substances, highlighting the need for further investigation.

Eating Less Fat At One Meal May Lead To Higher Fat Intake Later

A new study found that people who eat low-fat lunches compensate by eating more fat or carbohydrates at other meals, leading to similar daily fat and carbohydrate intake levels. The brain's biochemical signals play a major role in food choices, particularly where fat, carbohydrates, and total calories are concerned.
