Big news story: protein

Choc46

Hi everyone


Big news story 20 mins ago from University of California: lots of animal protein (protein greater than 10% of overall calories) in your diet during middle age increases your risk of cancer four times!!!!

I've had a lot of success over the last few weeks with eating protein (mainly tuna and chicken) at every meal. Very confused now.

In to see where this goes.

Old news and totally bias.

Whenever a story reports on a study without actually linking to said study, it's generally crap.

No sources. Who'd have thunk it?

I agree. They can easily cherry pick quotes from the summary or other parts to make it sound like what they want.

I really doubt this study has been able to establish causality. Correlation, yes, but what else did they control for? What kind of study was this (longitudinal, cross-section, etc)? How did they determine the subjects' diets? So much that the article is leaving out.

Not to mention, they say higher protein is risky in "middle age" but protective in "advanced age." Without really saying what those age groups mean (they mention 65, but not necessarily as a boundary age), those statements don't mean much at all. Ambiguous report is ambiguous...

Their reasoning seems to be 'controlling IGF-1 and insulin levels' through less consumption of protein? What?

Eat low protein in middle age, then more protein again as you get older...

This is a steaming pile of.... terrific research based reporting! :laugh:

I can't help but feel the irony as I read this article eating ham and cheese, and not giving one single firetruck.

I remember being in high school and being taught that eggs were soooo bad for you and carbs were soooo good for you. Now water is bad if you drink it out of a plastic bottle. Why don't we all try this new diet - if it wasn't around 2000 yrs ago - don't eat it!

So, just bread? No foods around today were around 2000 years ago. In fact, there are very few foods today that were around even 500 years ago.

Even fruits and vegetables have been modified to be easier to eat.

Here's the paper:

And here's what New Scientist has to say about it:
http://www.newscientist.com/article/dn25158-i-can-has-cheezburger-protein-cancer-risk-overblown.html

I wasn't happy to see the news story because in January I changed my macros to 40/30/30 C/F/P which was a big increase in protein for me. And I'm in their designated danger zone age range. :ohwell:

first my ice cream, next my cookies then my jelly beans now my meat?

ugh! what am i gonna eat now?

Where's the info on the 75% higher risk? How much protein are they talking about in grams?

Inherent problems with mouse studies to start with and IGF1 in humans don't show the same effects. Secondly the data collected was a 24 hour recall from the previous day, then extrapolated over the next 18 years.........kinda like paint by numbers.

From http://download.cell.com/cell-metabolism/mmcs/journals/1550-4131/PIIS155041311400062X.mmc1.pdf

"Using Cox Proportional Hazard models we found no association between protein
consumption and either all-cause, CVD, or cancer mortality (Table S2). However, high
and moderate protein consumption were positively associated with diabetes-related
mortality. One explanation is that diabetes may be more prevalent in these groups,
possibly because of a switch to a higher protein, lower fat, and lower carbohydrate intake
following a diabetes diagnosis."

High protein is 94 g/day. Risk table :-

It says here that a man my age should only be eating 60g of Protein per day, but that I can go up to 92g once I clear 65y.o.

I've begin eating anywhere from 1-1.3g protein per pound body weight for the past 3 years. I feel fine.

CW: 142.8lb
Protein: 150g+

These studies are invalid.

Every study contradicts every other study. Just eat like a human and cut back on the processed crap.
