Protein in the Media: Sensationalism or Science?

Once again, the media has made some sensationalistic headlines regarding protein intake:

High-protein diet ‘bad as smoking’

When something like this pops up, I generally get a plethora of emails asking my opinion; more often than not, it just requires a deeper look at the actual study.  And, unfortunately, a bit of a background check into the study authors.  Some key points from the study at hand:

  • This was a combo of two studies.  The first part is an epidemiological observational study—NOT a randomized, controlled study in humans.  While epidemiology is important, the results can only be CORRELATIVE.  Not causative.  So it raises more questions than answers, and that’s is what they are designed to do.
  • The second part is a mouse intervention study; the mice were implanted w/ cancerous tumors, and growth was studied with measured protein intake, based on IGF-1 (insulin-like growth factor 1).  While high protein DID raise IGF-1 and it DID cause the implanted tumors to grow, this DOES NOT mean high protein intake in humans will CAUSE cancer.  IGF-1 is a non-selective growth hormone.  It’ll cause everything to grow—muscle mass, tumors, and increase bone density.
  • The human epidemiological study used dietary analysis by self-reported recall, and did not control for quality.  A high intake of protein from grass fed beef, organic chicken coupled with whole fruits and vegetables is NOT the same as a high protein diet from pizza, fast food, and highly processed foods.   The key factor here?  Inflammation and sedentary lifestyle.
  • In an eerily similar T Colin Campbell and Ancell Keys fashion, the published “results” are highly skewed based on the data.  One very salient point:

The low protein cohort 9.8% died of cancer. In the moderate and high protein diet 10.1% and 9.0% died of cancer.

Jumping to conclusions about protein intake and cancer, based on this, is borderline negligent.

Another interesting point:  The authors state their was a “non-significant trend” in that soy based protein was better that casein”.  Luongo is quoted as saying “Some proteins are better for you than others, for example plant-based proteins like beans”.  No where in the data is this shown, and there was no difference in tumor growth.

Last point, but an important one:  Luongo, the lead researcher, is the founder of L-Nutra, a company that makes plant based meal replacement drinks.

Verdict?  Flawed biased science and media sensationalism.

    Couldn’t get it today. I think I’m physically spent due to not taking Sunday off and trying 14.2 a second time. Looking forward to resting on Thursday!

    CBGB felt good. T2B as well, PC + Jerk was better at last minutes, i felt tight in shoulders since yesterday.
    1k row was good, 1:49/500m tempo, DU wash´t good, it should and use to be UB but trapped 3-4 times. WB was awful, plan was to split in 2 but i had absolutely no power in my legs or in my shoulders, did 20/15/10/8/7/8/7.
    Ouch! It seems like yesterday was tough to me. 🙂

  3. Holy shit, I was waiting to hear who had a vested interest in that idiotic study but I can’t believe it was actually one of the researchers? It blows my mind the media, who came up with the comparison between meat and smoking, are so stupid they’d bother to print this stuff. Next up: New Research Shows Earth is Flat.

    what would be a good weight % for cgbp and weight for the double kb front racks? Also what would be a good substitute for the heavy med balls?

    Thanks

  5. Question….

    Workout for “will” states:

    10-8-6-4-2
    CGBP
    Row Cals
    +
    3rds for time

    When the plus sign “+” is there, what does that mean? Is it that both portions are always on the same clock or that they’re two separate workouts with a rest period in between?

    10:42 (4:02 row, mostly sets of 20 on the du, pushed on the wb but many sets)

    Quite pleased with the wb today. I have a tendency to talk myself into pacing too much (“just do five or you won’t make it”) but today I tried to not listen to that voice and push through, even if it sometimes was just one rep or two.

    DU’s were not good and WB’s were exhausting and were tough. Really felt like my conditioning was not up to where my work capacity wanted to be.
