1. Nutritional differences between organic milk and ordinary milk
In the United States, dairy products are the second largest category of organic food after vegetables and fruits. Although sporadic studies have found that some nutritional indexes of gold may be slightly higher than those of organic food, on the whole, organic food is not more nutritious than ordinary food. At present, no research shows that eating organic foods such as dairy products and meat can reduce the risk of some chronic diseases.
At most, individual studies show that some biomarkers are different. In addition, some organic milk may have a high content of ε-3 fatty acids, but from the perspective of public health or dietary advice, these differences have no physiological significance. For example, a glass of milk may contain 20 mg of ε-3 fatty acids, which is very significant compared with ordinary milk, but it is very small compared with the dosage of hundreds or even thousands of milligrams that we want to achieve for health. As mentioned above, considering the amount of saturated fat, if we drink a lot, we will recommend eating low-fat or skim milk. Under this premise, the difference of fatty acids between natural and organic milk will be smaller, so nutrition is not the reason to choose organic food.
2. The meaning of organic food
Regarding organic standards, domestic standards are actually very strict, and it is a good wish to be stricter several times ... It is hoped that the dairy farming process will be more helpful to the environment through the farming system of organic agriculture.
According to the organic standards in some areas, cows must be fed organic feed, and hormones and antibiotics cannot be used, and by-products from animal slaughter cannot be used as feed. Cows must be managed by organic standards for at least 12 months before they can be labeled as organic milk. It is necessary to adopt some preventive management measures to ensure the health of animals. Cows should have pasture for grazing and should be outdoors all year round. Only under special circumstances, for environmental or health reasons can they be confined indoors. The specific standards can be distinguished by the relevant certification marks.
Generally speaking, the standards of organic food are indeed very strict, but its significance may be difficult to directly benefit consumers through products.
