Milk seems to be making its way through
various stages of truth, especially within the past couple of years.
Like many other examples, what we once thought to be healthy for us to
consume is turning out to be the exact opposite.
A large study coming from researchers at
the Uppsala University in Sweden found that drinking milk led to an
increased mortality rate and actually made bones more prone to
fracturing, not less.(1)
The study was recently published in the peer reviewed British Medical Journal, and
was specifically conducted to examine whether high milk consumption is
associated with mortality and fractures in both men and women.
The study took place across three
different counties in Sweden, and used data from two large Swedish
cohorts, one with 61,433 women aged approximately 39-74 years old and
one with 45, 339 men aged approximately 45-79 years old. They were all
administered food frequency questionnaires. The study used
“multivariable survival models” that were “applied to determine the
association between milk consumption and time to mortality and fracture.
The results were as follows:
“During a mean follow-up of 20.1
years, 15 541 women died and 17 252 had a fracture, of whom 4259 had a
hip fracture. In the male cohort with a mean follow-up of 11.2 years,
10 112 men died and 5066 had a fracture, with 1166 hip fracture cases.
In women the adjusted mortality hazard ratio for three or more glasses
of milk a day compared with less than one glass a day was 1.93 (95%
confidence interval 1.80 to 2.06). For every glass of milk, the adjusted
hazard ratio of all cause mortality was 1.15 (1.13 to 1.17) in women
and 1.03 (1.01 to 1.04) in men. For every glass of milk in women no
reduction was observed in fracture risk with higher milk consumption for
any fracture (1.02, 1.00 to 1.04) or for hip fracture (1.09, 1.05 to
1.13). The corresponding adjusted hazard ratios in men were 1.01 (0.99
to 1.03) and 1.03 (0.99 to 1.07). In subsamples of two additional
cohorts, one in males and one in females, a positive association was
seen between milk intake and both urine 8-iso-PGF2α (a biomarker of
oxidative stress) and serum interleukin 6 (a main inflammatory
biomarker).” (1)
The study concluded that high milk
intake was associated with higher mortality in one cohort of women and
in another cohort of men, and with higher fracture incidence in women.
It also concluded:
“Given the observational study
designs with the inherent possibility of residual confounding and
reverse causation phenomena, a cautious interpretation of the results is
recommended.”(1)
This Is Not The Only Study That Suggests Milk Is Not Good For Our Body
In a paper published in the Journal of the American Medical Association Pediatrics, Harvard
pediatrician David Ludwig emphasizes that bone fracture rates tend to
be lower in countries that do not consume milk. compared to those that
do, also noting that there are many other sources of calcium. (source)
Another study published in the American Journal of Public Health showed that dairy consumption might actually increase the risk of fractures by 50 percent. (2)
Studies have also shown that calcium
isn’t as bone protective as we thought. Multiple studies on calcium
supplementation have shown no benefit in reducing bone fracture risk. In
fact, vitamin D appears to be more effective when it comes to reducing
bone fracture risk. (3)
Studies have also shown that dairy products might increase a males risk of developing prostate cancer by 30 -50 percent. (4)
The list literally goes on and on.
It’s also interesting to note that
approximately 65 to 75 percent of the total human population on our
planet have a reduced ability to digest lactose after infancy. (5)(6) In some countries, over 90 percent of the adult population is lactose intolerant, think about that for a moment.
Lactose intolerance is an impaired
ability to digest lactose, a sugar found in milk and other dairy
products. Lactose is normally broken down by an enzyme called lactase,
which is produced by cells in the lining of the small intestine.
Keep in mind that the milk we have so
much trouble digesting after infancy is cows milk, not our mother’s
natural breast milk. In fact, we are the only species on Earth that
consumes the milk of another animal.
Since lactase’s only function is the
digestion of lactose in milk, most mammal species experience a dramatic
reduction in the activity of the enzyme after weaning. Lactase
persistence in humans has evolved as an adaptation to the consumption of
non-human milk and dairy products consumed beyond infancy. Our diet has
changed a lot, and as a result some of our genes have adapted, but it’s
not an easy process. This is why most humans are lactose intolerant.
Every other species weans and then never
drinks milk again for the rest of their lives, and because of that they
don’t have an enzyme to break down the sugar in milk. But during human
evolution, some humans experienced a mutation in the LTC gene, the
lactase gene, these mutations allow us to process lactose as adults.
With approximately 65- 75 percent percent of humans on the planet unable
to properly process it, it is evidence enough that we are not doing
what is natural and in accordance with our bodies.
Below is a video of Katherine S. Pollard, a PhD at the University of California, San Francisco going into more detail from the above paragraph.
Milk/Dairy Is Not The Only Source of Calcium
This list is extremely long, here is a very small list of non dairy/vegan sources of calcium, many of them out there provide a healthier source and even more of it. It’s important to do your research, there are so many foods out there that contain a healthy and abundant source of calcium.- Kale: One cup of raw kale is loaded with calcium, approximately 90 mg to be exact. This means that a 3.5 cup of kale salad provides more calcium than a one cup class of milk
- Oranges: One Naval Orange contains approximately 60 mg of calcium
- Beans
- Green Peas
- Chickpeas
- Quinoa
- Seeds
- Hemp
