One thing that can be harmful between bovine secretions and rice milk is arsenic (especially if contaminated water gets into the milk).
This [study] suggests that both components of reconstituted formula—the powder and the water with which it is mixed—can be sources of arsenic exposure for formula-fed infants. Conversely, breast milk has been found to have relatively low concentrations of arsenic, even in women with high exposure via their drinking water.—
Estimated Exposure to Arsenic in Breastfed and Formula-Fed Infants
The EPA likewise said that bovine milk does not contain as much arsenic from cows ingesting it in particular, however this does not keep it from being more concentrated in an infant formula that is bovine based. "
The most commonly used infant formulas contain purified cow's milk whey and casein as a protein source". Another
study reports that some of this depends on how much arsenic a cow ingests though: "
In the experiments with lactating dairy cows, significantly higher levels of arsenic in milk were observed for cows fed either 3.2 or 4.8 mg of arsenic per kilogram of body weight from arsanilic acid or 3-nitro ".
Also, mycotoxins in plant beverages can be reduced through cooking, possibly during production, whereas they cannot be reduced at all through pasterurization or cooking with cows milk.
Aflatoxins decompose at temperatures of 237–306°C (Rustom, 1997); therefore, pasteurization of milk cannot protect against AFM1 contamination. Awasthi et al. (2012) reported that neither pasteurization nor boiling influenced the level of AFM1 in bovine milk. However, boiling corn grits reduced aflatoxins by 28% and frying after boiling reduced their levels by 34–53%.
Aflatoxins: A Global Concern for Food Safety, Human Health and Their Management
"
Data show that there is a seasonal trend in the levels of mycotoxins in milk, with these being higher in the cold months probably due to the prolonged storage required for the cattle feeds providing favorable conditions for fungal growth.":
Mycotoxins in Bovine Milk and Dairy Products: A Review
Keep in mind that bovine milk is plant milk, because cows are fed plants, and apparently the toxins in such plant feed are present in cow milk. What makes dairy worse, as far as this goes, is that the toxins are harder to remove from milk than the plant foods, when prepared for human consumption. Rice for example can have its arsenic levels reduced by 60% if cooked in excess water and drained, whereas cows are fed things like rice bran, which is not prepared this way, so their milk may contain more arsenic from rice than rice milk would, if prepared carefully. I wouldn't presume that anything is prepared carefully though. High levels of arsenic have been found in rice milk and rice bran, so either type of milk should be avoided for that matter (rice gets more attention for arsenic content, but maybe they should have to list what the cows ate as ingredients in milk too, because it's in there—yes, it isn't just that you are what you eat, it's that you are what you ate eats—you are an ateeat)!
Adding to this, I was checking out some more info (mostly from the World Health Organization), which indicates that cow's milk would be a reservoir for contaminants, health concerns, etc... this is to a greater extent or potential than so-called plant milks, because such things accumulate in the animal milk fat.
Chemical Composition, Metals Content and Pesticide Residues in Raw, Pasteurized and UHT Milk and Their Dietary Intake:
Milk is one of the basic foods which is liable to be contaminated by toxic substances, such as heavy metals and pesticides.
These elements in milk are of particular concern because milk is largely consumed by infants and children.
Dioxins and their effects on human health:
Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer. Dioxins are found throughout the world in the environment and they accumulate in the food chain, mainly in the fatty tissue of animals. More than 90% of human exposure is through food, mainly meat and dairy products, fish and shellfish.
Evaluation of Dioxin in U.S. Cow's Milk:
Milk fat is likely to be among the highest dietary sources of exposure to persistent, bioaccumulative, and toxic (PBT) contaminants, thus it is important to understand PBT levels in milk.
Learn about Polychlorinated Biphenyls (PCBs):
PCBs have been demonstrated to cause a variety of adverse health effects. They have been shown to cause cancer in animals as well as a number of serious non-cancer health effects in animals, including: effects on the immune system, reproductive system, nervous system, endocrine system and other health effects. Studies in humans support evidence for potential carcinogenic and non-carcinogenic effects of PCBs. The different health effects of PCBs may be interrelated. Alterations in one system may have significant implications for the other systems of the body. The potential health effects of PCB exposure are discussed in greater detail below...
Persistent Organic Pollutants (POPs):
PCBs accumulate in human adipose tissue and breast milk.
The levels of PCBs found in different foodstuff are:
•animal fat: 20 to 240 µg/kg
•cow's milk: 5 to 200 µg/kg
•butter: 30 to 80 µg/kg
•fish: 10 to 500 µg/kg, on a fat basis. Certain fish species (eel) and fish products (fish liver and fish oils) may contain much higher levels, up to 10 mg PCBs/kg
•vegetables, cereals, fruits, and a number of other products: <10 µg/kg
•Main causes of concern regarding PCBs are: large fish, shellfish, marine mammals, meat, milk, and other dairy products.
Diet, nutrition and chronic diseases in context:
Consumption of formula instead of breast milk in infancy has also been shown to increase diastolic and mean arterial blood pressure in later life... current evidence indicates adverse effects of formula milk on cardiovascular disease risk factors; this is consistent with the observations of increased mortality among older adults who were fed formula as infants.
Report on Carbon Footprint Due to Milk Formula:
If all the immense resource costs of formula feeding were properly accounted for, the baby food industry would be closed down, and mothers paid to breastfeed.
Guidelines on food fortification with micronutrients:
As the vitamin C content of cow’s milk is low, infants represent a further subgroup that is potentially highrisk for vitamin C deficiency. There have been a number of reports – across several world regions – of scurvy in infants fed on evaporated cow’s milk.
Chernobyl: the true scale of the accident:
Residents who ate food contaminated with radioactive iodine in the days immediately after the accident received relatively high doses to the thyroid gland. This was especially true of children who drank milk from cows who had eaten contaminated grass. Since iodine concentrates in the thyroid gland, this was a major cause of the high incidence of thyroid cancer in children.
Maximum Residue Limits for Pesticides and Veterinary Drugs:
Residues in processed dairy commodities with higher fat content than milk will have a higher residue level in the processed commodity than in the raw product for fat-soluble substances.
Toxicological evaluation of certain veterinary drug residues in food:
Several studies have indicated that IGF I concentrations in human serum could be associated with nutritional status and milk intake. Milk consumption is particularly shown to be associated with an increase in concentrations of IGF I in plasma in both the young and adults.
In an intervention study, when men aged 55 85 years were instructed to drink three servings of nonfat or 1% milk per day as part of their normal diet, IGF I concentrations in serum increased significantly (10%) in the intervention group by the end of the 12 week intervention period compared with concentrations in those who maintained their normal diet.
High levels of circulating insulin-like growth factor-I increase prostate cancer risk:
Our data add further support for IGF-I as an etiologic factor in prostate cancer and indicate that circulating IGF-I levels measured at a comparatively young age may be most strongly associated with prostate cancer risk.
Relationship between Insulin-like Growth Factor-1 in diabetic mother’s breast milk and the blood serum of their babies:
There is evidence that the increased action of IGF-1 is likely in the offspring of diabetic mothers and represents part of the mechanism of fetal overgrowth.
Environmental rather than genetic fetal overgrowth:
Metabolic (environmentally induced) macrosomia is distinguished from genetic or constitutional macrosomia and is defined as the growth of a fetus beyond its genetic potential. It is characterized by excessive fat accumulation during fetal life.
Milk consumption during pregnancy increases birth weight, a risk factor for the development of diseases of civilization:
Current dietary recommendations for pregnant women intend to assure sufficient supply of calcium and high quality proteins for the growing fetus. However, there is more and more concern about milk’s role as a source of calcium. According to the recent opinion of Harvard School of Public Health milk isn’t the only, or even best, source of calcium. There are non-dairy foods including leafy green vegetables, broccoli, beans and tofu that supply high amounts of calcium. These calcium-rich food alternatives have a significant advantage in comparison to milk: they do not overstimulate mTORC1 signaling and most importantly do not transfer biologically active exosomal microRNAs.
We appeal to the medical community to define save upper limits for milk consumption during pregnancy, especially for those women who enter gravity with increased BMI.
Milk intake and risk of mortality and fractures in women and men:
A higher consumption of milk in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death.
Apparently the overconsumption of dairy milk is of particular concern at all ages (even prior to birth), and could be dangerous to promote drinking exclusively for nutritional benefits, while ignoring the potential for associated health problems. Especially when milkfat is consumed in addition to other animal fats.
