Letâs take a look at these two foods and see what the scientific community has to say.
Healthy Nutrients in Cow’s Milk
Cowâs milk, despite all the bad press, has an impressive array of nutrients. Cowâs milk is a good source of vitamins B12, B2, and D. This animal milk also contains phosphorus, calcium, and iodine. Whole cowâs milk is a good source of protein, plus it contains a healthy dose of omega-3s in the form of alpha-linolenic acid. The fat in milk produced by grass-fed cows contains a 2:1 ratio of omega-6 to omega-3s.
As for phytonutrients, drinking a glass of cowâs milk will net you some beta carotene, and the isoflavonoids formononetin, biochanin A, and prunetin.
Healthy Nutrients in Goatâs Milk
Now, what about goatâs milk? Goatâs milk has many of the same nutrients as cowâs milk. However, the vitamin A found in goatâs milk is more readily absorbed by the body. Goatâs milk also has more vitamin B2 (riboflavin) than cowâs milk. And this animal milk contains more protein and calcium per serving than conventional cowâs milk. Goatâs milk is also a good source of bio-organic sodium which helps in the production of digestive enzymes.
So far so good, for both cowâs milk and goatâs milk. But when researchers recently compared the two milks, they found that goatâs milk edged out cowâs milk in the prevention of certain diseases like anemia and loss of bone minerals. The researchers also found that goatâs milk was better able to stabilize calcium balance.
This, they say, was because of the better bioavailability of iron, magnesium, phosphorus, and calcium in goatâs milk. Goatâs milk also had a beneficial effect in regards to levels of parathyroid hormone. This hormone helps to regulate calcium balance.
The researchers concluded that regular consumption of goatâs milk exerts positive effects on mineral metabolism, anemia, and bone strength. Unlike cowâs milk, calcium found in goatâs milk doesnât interfere with the bioavailability of important minerals found in the milk.
In another study conducted at the Jeanne de Flandre Childrenâs Hospital in Lille, France, researchers reached a different conclusion about the cowâs milk vs. goatâs milk debate. They note that despite the high fat content in cowâs milk, it doesnât seem to lead to any greater risk for heart disease factors.
They also pointed out that cowâs milk likely protects against colorectal cancer. They found no evidence that a diet free from cowâs milk will protect against the onset of autism in children (a hot topic amongst parents and medical professionals alike).
They mention that goatâs milk isnât suitable for infants because itâs high in protein and has low levels of folate. The research team concluded by emphatically stating that goatâs milk isnât any more superior to cowâs milk nor does it trigger any less allergic response in people who drink it.
The debate will continue, no doubt. But for those who do have a sensitivity to cowâs milk, goatâs milk has been proven as a viable alternative.
