Quite a few meals checks reveal contamination is a major downside, and whereas authorities insist ranges are unlikely to do any hurt, they’re speaking about contaminants present in anybody given meals — not the degrees you is likely to be uncovered to by consuming all of them together, day-after-day of the yr for a lifetime.
Frequent contaminants present in meals embrace herbicides and pesticides, medication, heavy metals and environmental contaminants resembling dioxins, PCBs and the flame retardant PFOA.
Most lately, checks performed by Emory College researchers and The Natural Heart reveal a good portion of standard nonorganic cow’s milk offered in grocery shops across the U.S. accommodates pesticides, development hormones and antibiotics, together with some that aren’t legally permitted in dairy manufacturing. Natural milk, then again, was not discovered to comprise these contaminants.
One-third of standard milk accommodates dangerous contaminants
The examine1,2 was printed on-line June 26, 2019, within the Public Well being Diet journal. Half-gallon jugs of standard milk and natural milk have been randomly bought at retail shops in 9 U.S. areas — 35 standard milk samples from 18 manufacturers and 34 natural milk samples from 10 manufacturers.Three
The 69 samples have been examined for the presence of pesticides, antibiotics, bovine development hormones (bGH) and insulin-like development issue (IGF-1) utilizing liquid or gasoline chromatography and mass or tandem mass spectrometry. Of the 35 standard samples examined:four
• 60% have been discovered to comprise antibiotics, together with amoxicillin, oxytetracycline, sulfamethazine, sulfadimethoxine and sulfathiazole
• The banned antibiotic sulfamethazine was present in 37% of samples, and sulfathiazole — additionally banned in dairy manufacturing — was present in 26% of samples.
Sulfanomide antibiotics aren’t allowed to be used in dairy manufacturing as a consequence of human well being considerations, which embrace acute and doubtlessly life-threatening allergic reactions5 and different negative effects,6 together with joint and muscle ache, belly cramping and low again ache
• One pattern (Three%) contained the antibiotic amoxicillin, generally utilized in human medication, at a stage exceeding the federally permissible restrict
• Between 26% and 60% have been discovered to comprise pesticides, together with chlorpyrifos (59%), atrazine (26%; linked to reproductive hurt in animals, beginning defects and most cancers), diazinon (60%), cypermethrin (49%) and permethrin (46%; an artificial pyrethroid7 insecticide linked to conduct issues in youngsters)
• 59% contained chlorpyrifos, an insecticide recognized to disrupt mind improvement and trigger mind injury, neurological abnormalities, lowered IQ and aggressiveness in youngsters
None of these pesticides and antibiotics have been discovered within the 34 natural milk samples. In response to the authors:eight
“Among the many standard samples, residue ranges exceeded federal limits for amoxicillin in a single pattern (Three%) and in a number of samples for sulfamethazine (37%) and sulfathiazole (26%). Median bGH and IGF-1 concentrations in standard milk have been 9·eight and three·5 ng/ml, respectively, twenty and thrice that in natural samples …
Present-use antibiotics and pesticides have been undetectable in natural however prevalent in conventionally produced milk samples, with a number of samples exceeding federal limits. Greater bGH and IGF-1 ranges in standard milk recommend the presence of artificial development hormone.”
Decide for natural milk to keep away from contaminants
In its press launch, Jessica Shade, director of science packages for The Natural Heart, mentioned:9
“This examine is particularly thrilling as a result of the researchers developed strategies which are extra delicate than previous analyses, together with testing strategies which were utilized by the Meals and Drug Administration (FDA); additionally, the examine measured ranges of chemical substances that have been beforehand unreported.
These new strategies give us a real image of the presence or absence of residues in milk. The methodology was confirmed and stable, and put methods in place to manage for outcomes that might inaccurately point out the presence or absence of the residues [false positives and false negatives].
The statistical significance was so clear and decisive that it offers us confidence that what we discovered within the examine would additionally be the outcomes of a bigger sampling.
Milk is a superb supply of protein and vital nutritional vitamins and minerals, and we would like our kids and our households to drink milk. However not all milk is created equal, as this examine demonstrates.”

Natural milk accommodates extra omega-Three fat and CLA
A 2016 report10 by the European Parliament, “Human Well being Implications of Natural Meals and Natural Agriculture,” which reviewed the dietary content material of organics (amongst many different issues) — together with natural milk — concluded that the clearest advantages of organics on human well being have been discovered to be associated to lowered pesticide, antibiotic and cadmium publicity.
In response to the authors of this EU report, “As a consequence of lowered pesticide publicity, natural meals consequently contributes to the avoidance of well being results and related prices to society.” Nonetheless, it has important dietary advantages over standard as effectively.
For starters, it has a more healthy ratio of omega-Three and omega-6. As famous in a 2013 examine,11 natural milk accommodates 25% much less omega-6 fat and 62% extra omega-Three fat than standard milk. In comparison with natural milk, standard milk had “a 2.5-fold greater omega-6/omega-Three ratio … (5.77 vs. 2.28),” and as famous by the authors:12
“During the last century, intakes of omega-6 (ω-6) fatty acids in Western diets have dramatically elevated, whereas omega-Three (ω-Three) intakes have fallen. Ensuing ω-6/ω-Three consumption ratios have risen to nutritionally undesirable ranges, typically 10 to 15, in comparison with a potential optimum ratio close to 2.Three …
All particular person ω-Three fatty acid concentrations have been greater in natural milk — α-linolenic acid (by 60%), eicosapentaenoic acid [EPA] (32%), and docosapentaenoic acid (19%) — as was the focus of conjugated linoleic acid (18%).”
In addition they investigated three hypothetical eating regimen methods to attempt to verify the best solution to attain a extra optimum omega-6/omega-Three ratio, concluding mixture of excessive natural dairy consumption together with lowered consumption of omega-6-rich meals “collectively would lower the omega-6/omega-Three ratio amongst grownup girls by ∼80% of the overall lower wanted to achieve a goal ratio of two.Three.”
This examine additionally discovered natural milk had greater ranges of helpful conjugated linoleic acid (CLA), which they notice is “broadly accepted as helpful for coronary heart well being and prevention of most cancers.”13 Total, CLA ranges in natural milk have been 18% greater than standard,14 though there are important seasonal variations.
The best CLA ranges are achieved in the summertime, Could by way of October, when CLA concentrations have been 55% greater than within the winter.15 Typical milk, then again, had a lot smaller seasonal differences in CLA, rising solely 12% in the summertime.16
Different analysis demonstrating superiority of natural milk
One other evaluation,17 printed in 2016, that regarded on the compositional variations of natural and standard milk,18 additionally discovered clear variations between the 2. Stated to be the biggest examine of its sort, the researchers analyzed 170 research on milk.
In response to this assessment, half a liter of natural full fats milk will give you an estimated 39 milligrams (mg) or 16% of the advisable each day consumption (RDI) of very long-chain (VLC) omega-Three (EPA, DPA and DHA), whereas standard milk will present solely 25 mg or 11% of the RDI of those vital fat.19
As famous by the authors, VLC omega-3s have been linked to quite a few well being advantages, together with “improved fetal mind improvement and performance, delayed decline in cognitive perform in aged males and lowered danger of dementia (particularly Alzheimer’s illness).”
And, whereas the variations in nutritional vitamins and minerals have been smaller than these of omega-Three fat, in comparison with standard milk, natural milk was additionally discovered to comprise 13% greater vitamin E ranges (alpha-tocopherol) and 20% greater iron ranges.20 As within the 2013 examine mentioned above, this evaluation additionally discovered natural milk had “considerably greater CLA” ranges.21
Natural uncooked grass fed milk is much less prone to make you sick
Final however not least, natural uncooked milk from grass fed pastured cows can be far much less prone to be contaminated with hazardous micro organism related with foodborne sickness. Natural farming and animal meals manufacturing usually are each safer on this regard, as mentioned within the EU report22 “Human Well being Implications of Natural Meals and Natural Agriculture,” which accommodates a bit on this subject.
Whereas the U.S. Meals and Drug Administration and the U.S. Division of Agriculture insist uncooked milk will improve your danger of loss of life and illness, foodborne sickness statistics supply no help for such claims. In reality, an investigation23 by Dr. Ted Beals reveals you’re 35,000 occasions extra prone to get sick from any different meals than uncooked milk.
Each the FDA24 and USDA25 warn that uncooked milk can carry disease-causing micro organism, — utterly ignoring and overlooking the truth that these micro organism are the results of industrial farming practices that result in diseased animals. Wholesome animals raised on pasture merely is not going to harbor harmful quantities of pathogenic micro organism.
The one manner their uncooked milk warning would make sense is that if it specified that it is best to by no means drink unpasteurized CAFO milk, as that would certainly be disastrous. Natural grass fed milk, then again, hardly ever ever poses a well being danger when consumed uncooked, offered the producer is following good, sanitary practices — and natural dairy farms are required to observe stricter protocols on this regard.
A 2012 investigation by Mark McAfee, CEO of Natural Pastures Dairy — which included a FOIA request to the Facilities for Illness Management and Prevention for knowledge on deaths claimed to be associated to uncooked milk — revealed:26
Zero deaths attributed to uncooked milk consumption in California over a 37-year span
The two deaths the CDC lists as being associated to uncooked milk have been really as a consequence of unlawful Mexican bathtub cheese, and never uncooked milk produced within the U.S.
The final individuals to die from milk died from contaminated pasteurized milk
In accordance to a Cornell examine, which used CDC knowledge, 1,100 diseases have been linked to uncooked milk between 1973 and 2009. In the meantime, 422,000 diseases have been traced again to pasteurized milk. And, whereas nobody died from uncooked milk, no less than 50 Individuals died from pasteurized milk or pasteurized cheese
Uncooked milk related to decrease an infection danger
Whereas being much less prone to make you sick, uncooked natural grass fed milk might also have immune-boosting advantages. In response to a 2015 examine27 in The Journal of Allergy and Scientific Immunology, youngsters who drink uncooked natural grass fed milk have decrease charges of viral and respiratory tract infections, together with common colds, than those that drink ultra-pasteurized milk. In response to the authors:
“Adolescence consumption of uncooked cow’s milk lowered the danger of manifest respiratory infections and fever by about 30% … [T]he public well being affect of minimally processed however pathogen-free milk is likely to be huge, given the excessive prevalence of respiratory infections in the primary yr of life and the related direct and oblique prices.”
Ensure you get what you pay for
Whereas natural milk is probably going a far superior alternative over standard milk, keep in mind that any natural milk offered in standard grocery shops will nonetheless be pasteurized, which can detract a few of its advantages, because the pasteurization kills helpful micro organism and may injury many worthwhile enzymes. To be taught extra, see McAfee’s article, “The 15 Issues That Milk Pasteurization Kills.”28
What’s worse, regulatory loopholes allow CAFO dairies to produce “natural” milk, regardless that the cows aren’t grass ate up pasture. I focus on this in “How Natural is Your Natural Milk?”
For optimum well being advantages, go for natural, grass fed uncooked milk, ideally licensed by the American Grassfed Affiliation (AGA), which ensures the very best high quality grass fed merchandise — each meat and dairy.
The AGA web site means that you can seek for AGA permitted producers29 licensed in keeping with strict requirements that embrace being raised on a eating regimen of 100% forage; raised on pasture and by no means confined to a feedlot; by no means handled with antibiotics or hormones; and born and raised on American household farms.
Different sources that may provide help to discover uncooked grass fed milk regionally embrace Uncooked-Milk-Details.com30 and RealMilk.com.31 They’ll inform you what the standing is for legality in your state, and supply a itemizing of uncooked dairy farms in your space.
The Farm to Shopper Authorized Protection Fund32 additionally offers a state-by-state assessment of uncooked milk legal guidelines.33 California residents may discover uncooked milk retailers utilizing the shop locator accessible at www.OrganicPastures.com.34
