Kids Who Drink Milk See Physical Benefits as Adults
Starting a milk drinking habit as a child can lead to lifelong benefits, even improving physical ability and balance in older age, according to new research. A new study published in Age & Aging found an increase of about one glass of milk a day as a child was linked to a five percent faster walking time and 25 percent lesser chance of poor balance in older age. The researchers suggest a "public health benefit of childhood milk intake on physical function in old age" – a finding that has huge potential for adults over 65, a population expected reach more than 70 million by the year 2030, doubling over just 30 years.
The team of British researchers used historical diet records from two large studies to assess the childhood habits of more than 1,500 men ages 62-86. They measured the impact of diet, specifically milk, protein, calcium and fat intake, on current performance and mobility in follow-up. Elderly participants were put through a series of activities, including walking, get-up-and-go and balance tests. Childhood calcium, protein and milk intake were all associated with advantages in mobility later in life.
The researchers also found that childhood milk drinkers were also likely to be adult milk drinkers, emphasizing the benefits of establishing lifelong healthy habits.
While decades of research support the bone-building benefits of milk, this is the first study to specifically find a physical performance benefit that can last a lifetime. Milk is the top food source of bone-building calcium and vitamin D in the American diet, and each glass provides 8 grams of high-quality protein. The 2010 Dietary Guidelines recommend two glasses of milk for toddlers (ages 2-3), 2.5 cups for children (ages 4-8), and 3 cups for adolescents, teens and adults.
