(The heavy weightlifting is a good concept, however the “GOMAD”? Not a lot…)
Not too long ago, although, milk has come below heavy hearth from the well being “gurus” of the world who not solely query its dietary worth, however go so far as labeling it a poison accountable for every kind of illness and dysfunction.
Drink milk, they are saying, and thanks to the lactose, pus, blood, hormones, and different “unhealthy” substances it incorporates, you’ll be extra doubtless to acquire weight, weaken your bones, and even get most cancers and die.
Lots of the folks making these arguments appear to have logic and science on their sides, too.
Perhaps they’re proper? Perhaps milk isn’t all it’s cracked up to be? Perhaps we’d all be higher off with out it?
Nicely, as you’ll quickly see, though the case in opposition to milk could be made to sound convincing, it’s primarily based on trumped up expenses.
Whenever you analyze the majority of the analysis, which we’re going to do on this article, the takeaway is obvious:
Milk will not be a magic bullet for bone well being, muscle acquire, or basic wellbeing, but it surely doesn’t deserve condemnation, both, and also you in all probability don’t want to cease ingesting it.

What Is Milk, Precisely?
A easy query, I do know, however most individuals can’t fairly reply it.
Milk is a mix of water, whey and casein protein, globules of fats, lactose (a easy sugar), and a few nutritional vitamins and minerals.
When it comes to energy and “macros,” a cup of entire cow’s milk incorporates about 145 energy, eight grams of protein and fats and 13 grams of carbohydrate.
Low-fat styles of milk include roughly the identical quantity of carbs and protein, however much less fats and thus fewer energy. For occasion, a cup of skim milk has about 90 energy, however the identical quantity of protein and carbs as entire milk.
Milk additionally incorporates a smattering of micronutrients as properly, particularly calcium, magnesium, phosphorus, and nutritional vitamins B12 and D (if fortified).

The 6 Greatest Lies and Myths About Milk
If you’d like to be fats, unhealthy, and illness susceptible, then you definately need to drink a whole lot of milk.
That’s what many individuals assume, no less than.
What are the arguments and counterarguments? And what does the scientific literature have to say?
Let’s sort out the massive 5 contentions that account for many of the hand-wringing over milk consumption.
“Milk Causes Weight Achieve”
Bodybuilders have been utilizing milk as a “bulking meals” for many years now, and for good motive.
In the event you’re struggling to eat sufficient energy to acquire weight, including a number of cups of milk to your each day meal plan could be a simple means to get the needle shifting.
That doesn’t imply milk straight causes weight acquire, although, as a result of no meals can automagically make you fatter and fatter just by consuming it.
Not milk, sugar, quick meals, or anything.
Keep in mind, it doesn’t matter what you eat, vitality steadiness dictates what occurs to your physique weight.
In different phrases, the actual determinant of physique weight isn’t meals selections however the relationship between vitality consumption and expenditure.
That’s why Professor Mark Haub was ready to lose 27 kilos in 10 weeks consuming Hostess cupcakes, Doritos, Oreos, and whey protein shakes.
And why this man misplaced 56 kilos in six months consuming nothing however McDonald’s, and this man received into one of the best form of his life following a rigorous exercise routine and consuming McDonald’s day by day for a month.
“What about insulin?” you may be pondering. “Doesn’t milk spike insulin ranges and thus fats acquire?”
Nicely, sure, milk does elevate insulin ranges, and insulin does play a job in fats storage, however, once more, that doesn’t imply that ingesting milk essentially makes you fats.
Solely overeating could cause important weight acquire. Once more, vitality steadiness is the important thing right here.
In the event you eat too many energy of the “cleanest” meals on the planet, you’ll acquire weight. And should you prohibit your energy, you possibly can eat nothing however junk and get leaner.
That’s why research have repeatedly proven that consuming dairy doesn’t trigger weight acquire, and, the truth is, analysis reveals that it can really allow you to reduce weight sooner (for causes primarily associated to satiety and portion management).
Now, one other declare typically made is that milk incorporates estrogen-like hormones that may trigger weight acquire and even feminizing results in males.
That is partially true.
Sure, milk does include these kind of hormones, however not in massive sufficient quantities to by itself have important results within the physique.
In the event you drank one and a half gallons of entire milk in a day, you’d enhance your complete estrogen ranges by not more than 1%.
Furthermore, most of of the estrogen-like compounds in milk are damaged down throughout digestion, rendering them physiologically inert.
So, the underside line is that this:
The one means ingesting milk could cause you to acquire weight is should you’re additionally commonly consuming extra energy than you burn.
And even then, do not forget that it’s the caloric surplus that’s driving your weight up, not the milk.
“Milk Weakens Your Bones”
For years, “everyone knew” that milk was good to your bones.
Now, nonetheless, a vocal minority is claiming that it really weakens them by stripping away calcium.
A examine generally adduced to assist this assertion is an evaluation of a pool of research that decided that dairy consumption wasn’t related to bone well being.
(I ought to word that this examine was funded by a vegan group that has lobbied for the USDA to take away animal merchandise as a meals group.)
Milk and dairy detractors have latched onto analysis like this as definitive proof of milk’s inferiority, however they’re lacking the forest for the bushes.
When evaluating the scientific analysis on, properly, something, you possibly can’t merely discover a examine that you simply like and placed on blinders. You will have to take a look at the remainder of the analysis on the matter and decide which means the literature is leaning.
And if you do this with milk and bone well being, the story is crystal clear:
Increased calcium consumption is related to better bone density, and this consists of calcium obtained from milk and dairy.
That doesn’t imply you have to drink milk and eat dairy merchandise to have wholesome bones, after all, but it surely does make it a lot simpler to give your physique the calcium it wants.
One other cost typically leveled in opposition to milk with regard to bone well being is that it’s an “acidic” meals that, in flip, makes your blood extra acidic, which then eats away at your bones over time.
That is utter tripe.
Analysis clearly reveals that no meals, milk or sugar or anything, can considerably impression the pH ranges of your blood.
That is excellent news, too, as a result of if meals may do that, you could possibly eat the incorrect kind of meal and die.
You see, your physique should regulate its blood pH very intently, very similar to temperature, and there’s little or no wiggle room.
This is likely one of the abdomen’s major features, really–it makes use of numerous chemical compounds to be sure that every thing that makes it by means of the processes of digestion is “protected” to be launched into the blood.
“Milk Incorporates Harmful Hormones”
Most cows are given hormones to enhance progress and milk manufacturing, together with recombinant bovine progress hormone (rGBH) and bovine somatotropin (bST).
These hormones do discover their means into the milk that’s on the cabinets of your native grocery retailer, and whereas that sounds ominous, it’s much less of a trigger for concern than many individuals assume as a result of the quantity is miniscule.
Many of the hormone molecules are destroyed throughout pasteurization, and plenty of of those who aren’t are damaged down throughout digestion, leaving little or no to have an effect on your physique and well being.
One other milk-related hormone that has folks in a tizzy is insulin-like progress issue one, or IGF-1, which has comparable results within the physique as progress hormone.
This hormone is of course current in milk (at extraordinarily low ranges), and ingesting milk boosts your physique’s pure manufacturing of it, and these information are used to hyperlink milk consumption to most cancers.
That is comprehensible as a result of most cancers is, at backside, uncontrolled mobile replica. Thus, somebody with most cancers definitely wouldn’t need to do something to increase IGF-1 ranges, however that doesn’t essentially imply that growing IGF-1 manufacturing at all times will increase the chance of most cancers in all folks below all circumstances.
This is the reason scientists haven’t but established whether or not elevated IGF-1 ranges can enhance the chance of most cancers or are merely a byproduct of it.
In different phrases, are we taking a look at causation or correlation? The literature hasn’t supplied a definitive reply but.
It’s additionally value noting that IGF-1 ranges are usually correlated along with your complete protein consumption, which is why even plant proteins elevate IGF-1 ranges (soy, for instance, much more than milk).
So by the “extra IGF-1 = extra most cancers” logic, a high-protein food regimen can be far “riskier” than average milk consumption. We all know there’s no credible proof that that is the case, nonetheless.
Moreover, whereas analysis has proven that individuals who eat extra dairy might have a barely larger threat of sure cancers, most research present that individuals who drink extra milk have the identical or a decrease threat of most cancers than individuals who eat much less dairy.
The most certainly motive for the discrepancy is confounding elements associated to life-style, like smoking, inactivity, and poor food regimen, which are recognized to enhance the chance of most cancers.
“Milk Is Too Processed to Be Wholesome”
In the event you’re to pay attention to the quack docs and “diet consultants” du jour, meals processing of any and every kind is dangerous.
That is foolish, and each time somebody tars a broad class or self-discipline with the identical brush like this, alarm bells ought to begin sounding in your head.
Sure, there are sorts of processing that produce unhealthy meals (oil hydrogenation, for instance), however in lots of circumstances, processing makes meals safer, tastier, and extra nutritious.
Within the case of milk and all different dairy merchandise, they undergo quite a lot of steps earlier than they’re deemed prepared to eat, with the massive ones being pasteurization, homogenization, and fortification.
Pasteurization is the method of heating milk to 161 levels (F) for 15 seconds. This kills any undesirable micro organism, guaranteeing the milk is protected to drink and lasts longer on the shelf.Homogenization is the method whereby fats globules are damaged into smaller ones and evenly dispersed all through the milk. That is accomplished to maintain the fats from separating from the remainder of the liquid and is often completed by forcing the milk by means of small holes.Fortification is the method of including nutritional vitamins and minerals into the milk to make it extra nutritious. Vitamin D is the most typical nutrient added, however calcium and omega-Three fatty acids are additionally typically included.
Regardless of the plain advantages of those processing strategies, many health-conscious folks have come to imagine that fully unprocessed (uncooked) milk is best for his or her our bodies.
There’s a sound argument to be made right here.
As a result of it’s not pasteurized, uncooked milk incorporates extra “good” micro organism that assist intestine well being, however there’s a draw back, as properly: uncooked milk additionally incorporates extra “unhealthy” micro organism that may trigger illness.
Uncooked milk advocates will level out that the chance of getting sick from dangerous micro organism current in uncooked milk is low, which is true, but it surely’s nonetheless a lot larger than with pasteurized milk. According to CDC information, uncooked milk is accountable for 71% of the circumstances of individuals getting sick from ingesting milk.
One other assault on pasteurization is the declare that it removes most or the entire helpful vitamins naturally present in milk.
That is an exaggeration.
Whereas it’s true that pasteurizing milk does downgrade its dietary worth, this shouldn’t impression the general nutritiousness of your food regimen.
The truth is until you’re getting the vast majority of your each day energy from milk (which might be silly), the dietary distinction between uncooked and pasteurized milk can have no bearing in your well being.
Both means, it’ll give you an abundance of calcium, and you’ll nonetheless want to eat beneficiant quantities of vegatables and fruits if you’d like to get enough quantities of the micronutrients that your physique wants to operate optimally.
“Milk Is Stuffed with Pus, Blood, and Somatic Cells”
Mmmm…pus, blood, and somatic cells…
This one has actually caught on as a result of, properly, it sounds disgusting.
It’s additionally deceptive, and to perceive why, we have now to evaluation how milk is collected from cows.
Most dairy cows are attached to mechanized gadgets for milking that join hoses to the udders to suck out the milk.
Whereas these machines are ready to gather milk sooner than folks can, they additionally trigger many cows to get an an infection referred to as mastitis, which leads to painful swelling of their udders.
This, in flip, triggers an immune response within the cows, which incorporates the elevated manufacturing of somatic cells to combat off the an infection. This does have an effect on the milk, which is why cows with infections produce milk with larger ranges of somatic cells than wholesome ones.
Moreover, when somatic cell depend is up due to an infection, white blood cell depend goes to be up, too, which is likely one of the major constituents of pus.
Thus, the declare that milk incorporates somatic cells and pus, which, we’d assume, isn’t good for our well being.
Nicely, to start with, milk by no means incorporates pus, however white blood cells. “Pus” was chosen for the needs of propaganda, although, as a result of it conjures nauseating photos, whereas “white blood cells” sounds benign.
Furthermore, the FDA maintains strict requirements for testing for milk for somatic cells and any contaminated batches have to be destroyed. Fines are additionally levied on farmers who persistently produce milk with unacceptable somatic cell counts.
Now, so far as blood in milk goes, it’s roughly the identical story.
Small quantities of blood can get into the milk if the cow’s udder is bruised or contaminated or if it’s harvested after birthing a calf. That is dealt with in the identical means as milk contaminated with somatic cells, although:
If it incorporates important quantities of blood, it’s thrown out.
So, whereas it’s truthful to say that milk that comes from wholesome cows is “higher” (most popular, actually) over milk from sick cows, it’s disingenuous to say that each one milk incorporates byproducts of illness that may, in flip, make us sick, too.
The Backside Line on Milk and Your Well being
Many well being and health “consultants” love to demonize meals.
They love to give folks scapegoats, panaceas, and quick-fix options as a result of, properly, it really works.
That’s why fad diets are the order of the day, and why so many individuals assume they need to keep away from so lots of the meals that they like, like sugar, meat, milk and dairy, and plenty of others.
Most of that is manufactured hysteria to promote capsules, powders, and food regimen and exercise packages.
A “wholesome” food regimen is way extra versatile than you’ve been led to imagine, and it will possibly embody roughly something that you simply like to eat, together with, properly, sugar, meat, and milk and dairy.
For milk’s half, it’s a reasonable supply of macro- and micronutrients, and is completely wholesome when included as part of a balanced food regimen.
Regardless of claims to the opposite, it doesn’t trigger weight acquire or most cancers, it doesn’t degenerate your bones, and it doesn’t include unhealthy quantities of hormones, pus, or blood.
