The biggest different many consumers note regarding organic and non-organic milk is the expiration date. Organic milk is able to sit for long stretches of time and for those used to having less than a week to consume their milk, this is quite a mystery. But there are many other differences between traditional and organic milk including the vitamin count and levels of toxins.
Milk and Contaminants
When you drink milk, you're consuming one of the healthiest foods for your body with calcium, protein and plenty of other vitamins that can ensure good health. Unfortunately, in most cases, you're consuming at least two types of pesticides arising from the feed consume by the cows, possibly strong antibiotics used to treat the animals and genetically modified hormones used to accelerate the growth of the animals.
Vitamins and Nutrients
In most cases, organic food is equitable in nutritional value to the non-organic varieties. In the case of milk, however, there are increased vitamins and nutrients in organic milk versus traditional milk. This was observed in the same USDA study that found an average of 2.5 accounts of pesticide residue in every samples of regular milk tested. The protein and vitamins are higher in the organic milk and this can only be attributed to the ultra pasteurization process, or more likely the higher quality diet of the organic cows.
