Most of us grew up hearing that milk “does a body good.” No one questioned this sentiment, what with parents, doctors and teachers all echoing the same sentiment, directly and indirectly. However, over the years, more and more research has emerged leading us to reevaluate the milk’s attributes and starring role in our lives. Is it key to good health or a health risk? Plus, with so many plant-based beverage alternatives flooding the market, who’s to say that cow’s milk truly is the best option?
Here are three arguments for drinking “moo juice” and three suggesting we should reconsider how much of it we drink.
It packs a single punch of needed nutrients
Our bodies need calcium, vitamin D and potassium to function properly. There’s no better single source for all three of these nutrients than milk. (For the record, vitamin D is added to fortified milk). Plus, it also contains carbs, fats, proteins and other minerals, all of which are a must for growing children, not to mention for aging adults – and everyone in between. True, milk isn’t the only source for all of these needed nutrients. As Americans don’t eat enough fruits and vegetables to meet the federal daily dietary guidelines, wouldn’t it be easier to get yourself – and especially your kids – to gulp down an extra glass of milk each day than to eat more vegetables?
Put simply, osteoporosis is the weakening of our bones. Each year, osteoporosis leads to millions of bone fractures. Increased calcium intake can help prevent or minimize its effects, as calcium is essential for building and maintaining our bones. Preventing osteoporosis depends on two things: strengthening your bone density early on in life and limiting the amount of bone loss in adulthood. How? By regular exercise and, especially, by getting enough calcium and vitamin D – particularly in the form of the milk. Dairy products have higher concentrations per serving of highly absorbable calcium than vegetables, beans and other alternatives.
It can help with weight loss
Milk contains a naturally high level of high-quality protein. In fact, it actually contains two types of protein, called whey and casein. By drinking just one cup of moo juice, you’ll get 8 grams of protein, which is more than double the amount most whole grains and fruits and veggies offer per serving. Why does this matter? Protein plays a big role when it comes to losing and maintaining weight. Among other amazing things, it helps reduce our hunger and appetite. So, one glass can cut off the urge to snack or overeat.
Actually, we don’t need so much milk
Can lead to increased health risks
Decades of research asserts that milk may contribute to health problems as opposed to preventing them. Some sources believe that the beverage’s high fat content can lead to an increased risk of Type 1 diabetes as well as coronary heart disease, heart attacks or strokes. Other research suggests that milk may lead to an increased risk of cancer due to the levels of IGF-1 growth hormones found in milk. While this hormone is normally found in our blood, higher levels of it may stimulate certain cancer cells.
Then, there’s a milk allergy, which can be life-threatening. Symptoms range from wheezing to vomiting to a possibly fatal anaphylactic reaction. To a lesser degree, there’s also lactose intolerance. The dairy beverage has also been associated with causing ear infections, coughs, and bloated, upset and gassy tummies. Last but not least, teenagers should be aware that various studies draw a distinct connection between drinking milk and increased acne.
Not proven vital for bone health
While milk has traditionally been considered the go-to source for maintaining bone health, recent voices suggest otherwise. For example, a 2011 scientific review found that drinking it did not reduce the risk of fractures in women. In fact, a 2014 study suggested that women who consumed large amounts of the dairy beverage may actually have a higher risk of fractures and death compared to others who drink less.
After infancy, we are not meant to digest dairy
As humans, we are not genetically programmed to drink milk after infancy. In fact, our gene that is required to break down milk sugar (lactose) turns off during weaning. Some researches argue that a genetic mutation is the only reason we, in the Western world (where dairying has been a longstanding tradition), can tolerate it as adults. But, on the whole, animals don’t drink milk after being weaned and they manage without it, especially since calcium and vitamins can be found in other sources or supplements.
Today, consumers are increasingly turning toward plant-based beverages, which are gaining in popularity and market share. Referred to by some as alt-milk, these alternatives, derive from oats, coconuts, soy, macadamia, rice and even peas, among other sources. They have become so popular that consumption has risen by 9% to US$1.6 billion in the 12 months through June 2018. So, it seems there may be a new trend taking off that our bodies prefer.
Bottom Line: We have long been told that drinking milk is a great (and convenient) way to boost daily intake of vitamins, minerals and protect bone integrity. However, research brings all of this reasoning into question. Would you consider switching to plant-based beverages the next time you reach for your coffee or a plate of cookies?
