Study Recommends Increasing Vitamin K2 Intake in Children
K2 is essential for bone growth, and since bones grow the most in childhood and teen years, it is especially important that children have adequate vitamin K2 intake. Vitamin K2 is also linked to the activation of proteins involved in oral health, proper brain development, and cardiovascular system development and function.
A new study has found that the change in food habits in developed countries has resulted in a significant decrease in vitamin K2 intake in children and adults. Many people are consuming less vegetables and more fats, oils, and processed foods. The decrease in vitamin K2 intake has been associated with poorer bone health and an increase in arterial calcification.
The researchers found that the rate of forearm fractures in children has increased over time. One study they looked at found that the rate increased 32% for boys and 56% for girls from 1971 to 2001. Low vitamin K2 status was positively correlated with an increased risk of forearm fracture.
The researchers also found that vitamin K2 deficiency may be associated with an increase in arterial calcification, even in children. Vitamin K2 helps keep calcium in the bones and reduces plaque buildup in arterial walls.
The researchers recommend supplementation with vitamin K2 in children who are deficient. Vitamin K2 can also be obtained through food sources such as high-fat dairy products, egg yolks, liver, unpasteurized cheeses, sauerkraut, miso, and natto.
The study was conducted by researchers from Jagiellonian University Medical College. It was published on January 5, 2022 in the journal Children.
