Animal protein fed to children associated with higher levels of body fat
Monday, December 10, 2007 7:52 am Email this article
Children who consume more animal protein, especially dairy protein, at the age of 1-year and 5- to 6-years-old have higher levels of body fat at the age of 7 than those who consume less according to a new study from researchers at the Research Institute of Child Nutrition at the University of Bonn in Dortmund, Germany. Dairy Protein
Dairy protein intake associated with higher levels of body fat at the age of 7-years : 18.2% vs 16.2%
At the age of one, the intake of dairy protein alone—not protein from meat or cereal—that was associated with a higher level of body fat at the age of 7.
At the age of 5-6, the intake of animal protein, not just dairy protein was associated with a higher level of body fat at the age of 7.
Those who consumed the most dairy protein at the age of 1-year had an average level of body fat at the age of 7-years of 18.2 percent versus 16.2 percent for those who consumed the least.
Vegetable protein intake is not associated with body fat
Intake of vegetable protein was not associated with body fat.
Conclusion: Higher dairy protein intake at 1-year is associated with higher levels of body fat at the age of 7
“A higher animal, especially dairy, protein intake at 12 [months] may be associated with an unfavorable body composition at 7 [years],” the authors of the study concluded.
“The age of 5-6 [years] might represent another critical period of protein intake for later obesity risk.”
