Organic dairy is better because it comes from organic livestock.
These means have respecting animal welfare without the use of antibiotics, synthetic growth hormones, and pesticide residues in every product.
Thanks to the research of the Organic Trade Center, we can say that organic milk has higher levels of heart-healthy omega-3 fatty acids.
Because antibiotics are not used on organic systems, organic is an important part of the solution to preventing antibiotic-resistant diseases.
Omega-3 fatty acids help to prevent cardiovascular disease, asthma, osteoporosis, breast cancer, prostate cancer, and inflammatory and autoimmune diseases. Low omega-6: omega-3 ratios, on the other hand, suppress these conditions (1).
Dairy cows under organic management eat more grass than those under conventional management, and that difference in their diet results in more nutrient-rich milk.
Everything starts with milk.
A recent study published in Public Health Nutrition shows the result of massive research. The research compares samples of milk being sold at grocery stores around the USA, comparing residues in conventional milk (35 samples across 18 brands) to organic milk (34 samples across 10 brands).
Three reasons to say that organic dairy is better
The following are the three main elements of the study that confirm why organic dairy is better:
- Growth hormone result
This study found levels of the bovine growth hormone (bGH), the precursor to IGF-1, to be 20 times higher in conventional milk than organic.
- Pesticides residues
The research shows that organic milk does not contain any residues of currently used pesticides or antibiotics and has lower levels of growth hormones than conventional milk.
Conventional samples, on the other hand, showed residues of several pesticides, including atrazine, chlorpyrifos, cypermethrin, diazinon, hexachlorobenzene, and permethrin (26%-60% of the samples). Pesticide levels in the conventional samples were below the FDA limit for all the pesticides.
Antibiotics were not found in organic samples but were detected in 60% of conventional milk samples. Also, 37% of the conventional milk samples showed residue levels of an antibiotic called sulfamethazine, and 26% of conventional samples showed residues of sulfathiazole, which are both banned for use in lactating cows.
Properties of organic milk
A study published in the British Journal of Nutrition (3) showed that organic milk had several beneficial increases in nutritional minerals and antioxidants, such as higher concentrations of iron, vitamin E, selenium, and carotenoids.
While several other studies have supported the benefits of consuming organic milk, this publication stood apart as the most comprehensive review conducted on this topic, drawing upon findings from 196 studies on milk from around the world.
In conclusion, we can say that organic milk and organic dairy is better because it is a wise choice to prevent diseases and respect animal welfare.
