Low-Protein Diet May Extend Lifespan

sciencehabit writes "A new theory about the foods that can extend life is taking shape, and it's sure to be a controversial one. Two studies out this week, one in mice (PDF) and another primarily in people (PDF), suggest that eating relatively little protein and lots of carbohydrates — the opposite of what's urged by many human diet plans, including the popular Atkins Diet — extends life and fortifies health."

    Ron, an elderly man in Florida, owned a large farm for several years. He had a large pond in the back.
    It was properly shaped for swimming, so he fixed it up nice with picnic tables, horseshoe courts, and some orange and
    lime trees.
    One evening the old farmer decided to go down to the pond, as he hadn't been there for a while, and look it over.
    He grabbed a five-gallon bucket to bring back some fruit. As he neared the pond, he heard voices shouting and laughing with glee.
    As he came closer, he saw it was a bunch of young women skinny-dipping in his pond.
    He made the women aware of his presence, and they all went to the deep end.
    One of the women shouted to him, "We're not coming out until you leave!"
    Ron frowned, "I didn't come down here to watch you ladies swim naked or make you get out of the pond naked."
    Holding the bucket up Ron said, "I'm here to feed the alligator."

  3. Misleading Summary; Less than exhaustive research. by digsbo · · Score: 5, Interesting
    Full article indicates the human study was based on a one-time interview with participants. Even then (FTFA): "as the NHANES cohort aged, protein became more important. In the over-65 crowd, those who ate lots of protein survived longer, on average, than those who ate less."

    So, sort of, maybe, but not.

    I'm pretty sure the Atkin's diet was ruled out by anyone with any knowledge of actual human health. The man died a fat, bloated fuck and doomed many of his blind followers to live the same.

    Um, I'm not an Atkins proponent (been vegetarian since the seventies) but part of that was marketing by Atkins detractors. He slipped on ice and suffered a severe blow to the head. In the hospital, he contracted another condition (which escapes me at the moment) which caused bloating. There is an urban legend that militant vegetarians (which always struck me as an oxymoron, but never mind...) snuck in and got photos of Atkins on his deathbed as rather disingenious "proof" that his diet killed him.

  5. Protein's Turn For Demonization by organgtool · · Score: 4, Insightful

    In the late 80's and early 90's, fat was the energy source of the devil that needed to be avoided at all costs. Then in the early 2000's, carbs were the new nutrient to avoid. And now, another decade later, they're telling us to avoid protein. I'll stick to eating a variety of foods in moderate portions supplemented by exercise, thank you very much.

    The best diet is probably a balanced diet of about 1200 calories a day. The safest way to avoid getting hit by a car is not to walk across streets or drive a car. The safest way to avoid dying via plane is to not fly, etc...

  10. Car analogy by istartedi · · Score: 5, Insightful

    Focusing on diet for human lifespan is like focusing on gasoline for car lifespan.

    Studies have been done of places where people tend to live longer. Some common threads are: genetics, happiness, close community ties, everyday physical labor, low stress, diet and maybe a few other things.

    Yeah sure, diet is in there; but if your Daddy died at 40, you're pissed off all the time, you don't know your neighbors and you spend 60 hours a day stressing in a cube-farm then the quinoa salad you ate probably won't help much. Go ahead though. It probably won't hurt; just don't expect miracles. Look at *all* the factors.

    Low Fat, Low Carb...oooh...hardcore...(thats what I did)...nearly died from that one...

    Yep, it's long been known that extremely high protein diets are bad for humans. I actually RTFA, and in the mouse study, it was a 50% protein diet. Mice are herbivores, that much protein is effectively toxic for them.

    So the mouse study doesn't show that low protein diet extends lifespan as much as a ultra-high protein diet reduces lifespan, which is not really news.

    The second study was an observational study of humans, which joins a long list of such studies where you'll find something to support pretty much any nutritional hypothesis you can imagine.

    Twin doctors, one eats nothing but fats and the other eats nothing but carbs, for a month. They document it, they work out, they do tests.

    http://www.bbc.co.uk/programme...

    The result (spoiler alert), either is not great. Eating only fat cannibalizes your muscles, and makes you not get any enjoyment out of food. Whereas eating only carbs makes you feel hungrier all the time.

    But their conclusion had a twist, the main problem is processed foods that have a 50/50 mix of fat and carbs. An excellent example is whipped cream. Your body would reject you drinking pure cream, and also pure sugar. But mix them together, and you cant stop eating it! Same with many of our favourite foods, ice cream, doughnuts. All have the 50/50 mix that vendors long ago realized was the most addictive mix. Your body basically never gets the signal to stop eating.

    Anyone who is interested should check it out.

    You can eat a tasty and balanced and varied diet on 1900 calories a day.

    So, would you rather have a tasty diet and live till 88, or eat the same tasty diet, just more of it, and die at 68?

    This is not the answer you would like, but I'll take 68 over 88 any day of the week

    My experience in my family and relatives has been that while we are really good at extending life, it's all on the wrong end of the lifespan. I've seen too many relatives who once would have made it to maybe 70, and now spend their last 15 years as demented zombies, kept alive by the miracles of modern medicine. They have low cholesterol, low blood pressure, and are having their savings, retirement ans SS checks going ot the nursing home, while they luxuriate in their Depends, catheters, and whatever experimental meds they give to Alzheimer's patients to keep them alive in order to extract those last pennies. Seriously undignified and unnaturally drawn out. THere are fates worse than dying.

    People in America get portions far larger then they need. People get used to over eating, so when they get a properly portioned meal they feel hungry, even though rationally they have enough.

    While I don't disagree with you that Americans overeat, the concept of getting people to eat less in times of plenty is going to be difficult to achieve. And the slovenly Americans are not the only people with an overeating problem.
