Lost in the battles over whether a dairy ought to be established on south Kauai pastures is the value of cow’s milk in human nutrition.
Milk has picked up a couple of gold stars in recent months, confirming once again that mom was right when she told you to drink it. But what perhaps hasn’t been clear is the importance of milk consumption in older adults.
Milk is important for supporting levels of anti-oxidants in the body, according to University of Kansas Medical Center researchers In-Young Choi, and Debra Sullivan. Their research was published in February 2015 The American Journal of Clinical Nutrition.
Choi said recent milk consumption was correlated with high levels of the brain anti-oxidant glutathione, which he said may help reduce oxidative stress that can cause diseases like Alzheimer’s and Parkinsons.
The editors of the American Journal of Clinical Nutrition cited the study as revealing "a provocative new benefit of the consumption of milk in older individuals."
An October 2014 study found that replacement milks like those from soy, nuts and even goats do not provide the vitamin D levels of cow’s milk. Kids who drink the alternative milks are twice as likely to have low Vitamin D levels, said researchers from the Canadian St. Michael’s Hospital. The work was published in the Canadian Medical Association Journal.
"Children drinking only non-cow's milk were more than twice as likely to be vitamin D deficient as children drinking only cow's milk," said St. Michael’s pediatrician Jonathon Maguire. "Among children who drank non-cow's milk, every additional cup of non-cow's milk was associated with a five per cent drop in vitamin D levels per month."
Vitamin D deficiency is associated with a variety of bone weakness diseases. Vitamin D supplements are an alternate means of getting the nutrient, as are certain fish. Although sun exposure can help with Vitamin D levels, there have been cases of Vitamin D deficiency even in sunny Hawai`i.
