The 6 Greatest Lies and Myths About Milk
If you wish to be fats, unhealthy, and illness inclined, then you definitely need to drink plenty of milk.
That’s what many individuals assume, at the least.
What are the arguments and counterarguments? And what does the scientific literature need to say?
Let’s deal with the large 5 contentions that account for many of the hand-wringing over milk consumption.
“Milk Causes Weight Acquire”
Bodybuilders have been utilizing milk as a “bulking meals” for many years now, and for good motive.
If you happen to’re struggling to eat sufficient energy to realize weight, including a number of cups of milk to your every day meal plan may be a simple technique to get the needle transferring.
That doesn’t imply milk instantly 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, power steadiness dictates what occurs to your physique weight.
In different phrases, the actual determinant of physique weight isn’t meals decisions however the relationship between power consumption and expenditure.
That’s why Professor Mark Haub was in a position 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 acquired 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 could be considering. “Doesn’t milk spike insulin ranges and thus fats acquire?”
Properly, sure, milk does increase 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 vital weight acquire. Once more, power steadiness is the important thing right here.
If you happen to eat too many energy of the “cleanest” meals on this planet, you’ll acquire weight. And should you limit 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, actually, analysis exhibits that it can really enable you to drop a few pounds sooner (for causes primarily associated to satiety and portion management).
Now, one other declare typically made is that milk accommodates estrogen-like hormones that may trigger weight acquire and even feminizing results in males.
That is partially true.
Sure, milk does comprise these kind of hormones, however not in massive sufficient quantities to by itself have vital results within the physique.
If you happen to drank one and a half gallons of entire milk in a day, you’d improve 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 method ingesting milk could cause you to realize weight is should you’re additionally frequently 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, nevertheless, a vocal minority is claiming that it really weakens them by stripping away calcium.
A examine generally adduced to help 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 notice 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, nicely, something, you possibly can’t merely discover a examine that you just like and placed on blinders. You need to have a look at the remainder of the analysis on the matter and decide which method the literature is leaning.
And if you do this with milk and bone well being, the story is crystal clear:
Larger calcium consumption is related to larger 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 present 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 exhibits 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 might do that, you may 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 capabilities, really–it makes use of varied chemical compounds to make sure that every little thing that makes it via the processes of digestion is “protected” to be launched into the blood.
“Milk Comprises Harmful Hormones”
Most cows are given hormones to extend progress and milk manufacturing, together with recombinant bovine progress hormone (rGBH) and bovine somatotropin (bST).
These hormones do discover their method 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 lots 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 individuals in a tizzy is insulin-like progress issue one, or IGF-1, which has related 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 info are used to hyperlink milk consumption to most cancers.
That is comprehensible as a result of most cancers is, at backside, uncontrolled mobile copy. Thus, somebody with most cancers definitely wouldn’t need to do something to spice up IGF-1 ranges, however that doesn’t essentially imply that growing IGF-1 manufacturing at all times will increase the danger of most cancers in all individuals underneath all circumstances.
For this reason scientists haven’t but established whether or not elevated IGF-1 ranges can improve the danger of most cancers or are merely a byproduct of it.
In different phrases, are we causation or correlation? The literature hasn’t supplied a definitive reply but.
It’s additionally value noting that IGF-1 ranges are typically correlated together with your complete protein consumption, which is why even plant proteins increase IGF-1 ranges (soy, for instance, much more than milk).
So by the “extra IGF-1 = extra most cancers” logic, a high-protein weight loss plan could be far “riskier” than reasonable milk consumption. We all know there’s no credible proof that that is the case, nevertheless.
Moreover, whereas analysis has proven that individuals who eat extra dairy might have a barely greater 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 probably motive for the discrepancy is confounding components associated to way of life, like smoking, inactivity, and poor weight loss plan, which are identified to extend the danger of most cancers.
“Milk Is Too Processed to Be Wholesome”
If you happen to’re to take heed to the quack docs and “vitamin consultants” du jour, meals processing of any and every kind is dangerous.
That is foolish, and every 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 varieties 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 able to eat, with the large 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 executed to maintain the fats from separating from the remainder of the liquid and is normally completed by forcing the milk via 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 individuals have come to consider that fully unprocessed (uncooked) milk is best for his or her our bodies.
There’s a legitimate argument to be made right here.
As a result of it’s not pasteurized, uncooked milk accommodates extra “good” micro organism that help intestine well being, however there’s a draw back, as nicely: uncooked milk additionally accommodates extra “dangerous” micro organism that may trigger illness.
Uncooked milk advocates will level out that the danger of getting sick from dangerous micro organism current in uncooked milk is low, which is true, but it surely’s nonetheless a lot greater than with pasteurized milk. According to CDC information, uncooked milk is answerable 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 all the 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 weight loss plan.
The fact is until you’re getting the vast majority of your every day energy from milk (which might be silly), the dietary distinction between uncooked and pasteurized milk could have no bearing in your well being.
Both method, it’ll give you an abundance of calcium, and you’ll nonetheless must eat beneficiant quantities of vegetables and fruit if you wish to get ample quantities of the micronutrients that your physique must perform optimally.
“Milk Is Filled with Pus, Blood, and Somatic Cells”
Mmmm…pus, blood, and somatic cells…
This one has actually caught on as a result of, nicely, it sounds disgusting.
It’s additionally deceptive, and to know why, we’ve got to evaluation how milk is collected from cows.
Most dairy cows are hooked as much as mechanized gadgets for milking that join hoses to the udders to suck out the milk.
Whereas these machines are in a position to gather milk sooner than individuals can, they additionally trigger many cows to get an an infection known as mastitis, which ends up in painful swelling of their udders.
This, in flip, triggers an immune response within the cows, which incorporates the elevated manufacturing of somatic cells to struggle off the an infection. This does have an effect on the milk, which is why cows with infections produce milk with greater ranges of somatic cells than wholesome ones.
Moreover, when somatic cell depend is up attributable to an infection, white blood cell depend goes to be up, too, which is likely one of the predominant constituents of pus.
Thus, the declare that milk accommodates somatic cells and pus, which, we’d assume, isn’t good for our well being.
Properly, to start with, milk by no means accommodates 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 constantly 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 method as milk contaminated with somatic cells, although:
If it accommodates vital quantities of blood, it’s thrown out.
So, whereas it’s honest 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 every one milk accommodates 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” like to demonize meals.
They love to present individuals scapegoats, panaceas, and quick-fix options as a result of, nicely, 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 most of the meals that they like, like sugar, meat, milk and dairy, and lots of others.
Most of that is manufactured hysteria to promote tablets, powders, and weight loss plan and exercise packages.
A “wholesome” weight loss plan is much extra versatile than you’ve been led to consider, and it may possibly embody roughly something that you just prefer to eat, together with, nicely, sugar, meat, and milk and dairy.
For milk’s half, it’s a cheap supply of macro- and micronutrients, and is completely wholesome when included as part of a balanced weight loss plan.
Regardless of claims on the contrary, it doesn’t trigger weight acquire or most cancers, it doesn’t degenerate your bones, and it doesn’t comprise unhealthy quantities of hormones, pus, or blood.
