Too much of anything... even protein...

In a recent study at UCLA, people 65 and under who ate a high-protein diet had four times the risk of death from cancer and diabetes and double the risk of death from any other cause. Protein activates IGF-1, a growth factor that pushes cells to age more quickly—which can cause DNA damage. Interestingly, moderate or high amounts of protein led to lower cancer and death rates for those over age 65. "Older adults tend to lose weight and be more frail, so for them, a boost in protein can benefit immunity," says study author Valter Longo.
Here's your age-appropriate protein prescription:
AGE: 65 or under → PROTEIN: 0.37 g per lb of body weight; about 55 g per day for a 150 lb person
AGE: Over 65 → PROTEIN: 0.45–0.5 g per lb of body weight; 68–75 g per day for a 150 lb person

Protein causes cancer and diabetes.
Carbohydrates cause cancer and diabetes.
Fat causes heart disease and makes you fat.
Guess I'm going to live off air because 100% of people who drink water die.0 -
Meh. I'll take my chances. We all die from something.
ETA: Also, "double the risk of death from any other cause"....am I more likely to die from a car crash because I eat extra protein????0 -

I wish they would've given the parameters of the study. There's much more to it than age and weight to determine protein intake. Activity level and goals play another part.0 -
I wish this article (which I clicked through to) had included 1) a link to the actual study, and 2) information about the activity level of the participants. Common sense says this would have in impact.
No offense to OP, but this should have been called "Too little information on too much protein."0 -

FINE! I'm holding my breath!0 -
Actual study not linked. The day I start trusting the analysis of article authors again is the day I give up trying to be better. Without the study, I can't determine if there's it's only a link that doesn't necessarily support cause = causation or if it's something to actually take into consideration.0

Yeah. Lots of people (here anyway) track their macros, protein in particular, for specific reasons. It's hard to extend the questionable results of the analysis out.0 -
The study was limited to people over the age of 50, mostly overweight and sedentary.
I'm 41. Not applicable.
ETA: here's another study. I like this study more. Strength train, y'all.

ETA 2.0: also UCLA.0 -
Most people who eat high amounts of protein and red meat over-consume and are over weight, are sedentary, and do not get enough fiber. If you statistically correct for these variables, then eating high protein has zero adverse health risks linked to it. Also, the part about diabetes is just a joke. This is a correlation study, doesn't prove causation. If you know anything about insulin and it's role in metabolic function you would know why this isn't true. Also, please don't ever link to an article on a women's fitness and nutrition website as evidence...0

boom.
Agreed...
That said, I personally believe in moderation of everything and eating a pretty well balanced diet which pretty much gives me a moderate intake of all three macros.0 -
Any information for those of us who actually, you know, go to a gym?0
-
Wasn't this the study that also showed improved health markers for over 65? Which pretty heavily calls into the question the validity of the study?
Apologies if I'm recalling the wrong study and linking something irrelevant but here:

Most of the time I see "HIGH PROTEIN BAD" it's mainly related to eating way too much red meat.0

Nope. You are correct. UCLA also came out with a study a little before this that indicated that adding lean mass to the body, through strength training and protein consumption, prolonged life.0 -
Soylent green must be the answer then, as human flesh is apparently the only thing that hasn't been shown to cause cancer yet.0

I'd be one stressed out mess if I bought into these types of articles. Everything's harmful these days.0

Thanks for taking the time to find and post these. Love the URL for the response -- guess it didn't go over very well, huh?

What were the parameters of the study? Did it include weight lifters, high-performing athletes, couch potatoes, or a random collection of people? What is considered a high protein diet? What lifestyle did these people have?
The protein intake suggested in your post is even less than the recommended daily allowance.
Prevention magazine is very far from my favorite source of information.0 -
The nerd scientists who did this don't even lift and they are jelly.0

Actually cannibalism is associated with a huge number of health risks and helps diseases spread.Soylent green must be the answer then, as human flesh is apparently the only thing that hasn't been shown to cause cancer yet.
It's the main reason we don't do it.
