On a side note, Linus Pauling was notorious for, late in life, after winning all his Nobels and other such prizes, pushing the idea that megadoses of Vitamin C would cure all cancers: https://en.wikipedia.org/wiki/Linus_Pauling#Medical_research...

He died in 1994, of cancer.

Well, he was 93 years old. That's still kind of beating the odds in a way.

>He died in 1994, of cancer.

Why is this brought out in such a dismissing and ironic way? He claimed that there may be some treatments with Vitamin C, not that if you take a little a day you'll be immortal. Hell, there are so many different types of cancer, that even if megadosing C helped with one it probably wouldn't help with all.

He lived to his 90s. At that point it was either cancer or heart disease that kills people. That fact that he lived to 93 is pretty impressive in itself.

As someone who recently went on Vitamin D supplements due to low D in my bloodstream, I find it incredibly interesting how medicine is always changing. This knee-jerk skeptic idea about how everything but the current accepted status quo is "quackery" and mocking guys like Pauling is reprehensible. Just a few years ago, no one was checking Vitamin D levels. Now my depression and lethargy have been turned way down as my Vitamin D increases.

Hell, I remember being a teen with ulcers and being told to lay off the spicy foods. I tried to explain to the doctor that I never eat that and he shrugged and wrote me a script for Zantac, it being prescription-only at the time. A few years later H. pylori's role in ulcer creation was revealed and now the standard treatment isn't large doses of zantac, but two weeks of amoxicillin. My ulcers magically went away after that treatment.

Medicine is one of things that moves fast and the jury is still out on a lot of marginalized treatments, concepts, and research. I wouldn't be surprised if Pauling's research eventually fleshed out into some kind of cancer treatment, or at least as a supplemental treatment.

I never understood the mocking, either, especially since he’s been proven extremely right about the ill-effects of consuming processed sugars. I suspect it’s rooted in his anti-nuclear and anti-war views and it just grew from there. His views on Vitamin C were just a convenient target.

It’s uncomfortable to those with analytical minds to accept the fact that we know so little about the human body and how it works. Studies are always contradicting each other because the scientific method dictates that studies must be reduced to the minimum of variables. But the body is far too complex for that. Most of what I was taught nutritionally in school as a kid was wrong. Most of the health advice was wrong. We were told butter is evil and we should eat margerine. We were told fat was evil and that cholesterol causes heart disease despite no evidence other than correlation. We don’t know how or even if consumed cholesterol gets turned into cholesterol in the bloodstream. It’s virtually universally believed that salt is bad despite it being an essential nutrient. It’s universally believed that sun is bad and we must slather ourselves with sunscreen and now we all have Vitamin D deficiencies. Read the literature that comes with any prescription drug and there will be a paragraph explaining that they have no idea how the drug works. Many are no more effective than a placebo. There’s a perception that has persisted most of my life that we are always at a point where we have these things figured out, but ten years later they are proven wrong, but we don’t seem to notice that.

There is an almost religious fervor surrounding science when it comes to our health and nutrition. Lots of research in the past few years surrounds gut bacteria, something that wasn’t even on the charts even 10 years ago. Now we are realizing that we not only know nothing, we know less than nothing.

I don’t think Pauling will be vindicated on Vitamin C because this came from a time when it was universally thought that there was a pill or an injecton for anything and we just had to discover it. If you read Pauling’s books, you’ll realize that he never advocated it as a panacea, but part of a complete dietary and mental regimen. His research is compelling and it’s not hard to see how he came to the conclusions that he did.

It’s good to hear I’m not the only one learning from history and realizing the uncomfortable fact that we know so little and this treatment of ulcers is the exception rather than the rule. How did we not discover this was bacterial for so long? It’s not like this is the 19th century after all.

Nutrition has changed far less over the last 50 years than you might think. The real issue is condensing it into sound bytes.

In a sound bite X More! vs. X Less! has a lot to do with peoples eating habits and overall health not just how good or bad X is.

Especially when it often breaks down as Benefits A, B, C vs. problems X, Y, Z. Yes, sometimes we add a benefit or risk to the list and or change the risk weights slightly, but rarely do things change all that much from one decade to the next.

I'm not very knowledgeable in this topic, but I think it's changed a lot. The way food is processed changes the way we're absorbing it.

Today's bread, milk, cheese, veggies, fruits are a bit different than 50 years ago - they last longer, taste different, probably because of how they're processed.

That lack of bacteria that makes things go bad faster should have a different effect on our bodies, no?

Re:Vitamin C kills tumor cells with hard-to-treat mutation i... by Retric on Monday November 09, 2015 @04:30PM (#10535968)
That's got little to do with what I meant.

Replace "Nutrition", with "Nutrition Science" or "Our understanding of the body's need for Nutrition" in my comment.

I've just been cured from another sickness caused by the same bacteria. Only one or two years of suffering, not so much, but enough to make my life miserable in so many ways.

The explanation I've read at Wikipedia is that it's an extremophile (digestive acids), so it could never be cultured until very recently.

I completely agree with you about lack of perspective in medical knowledge. Pros get all defensive instead of doing a bit of self-criticism. Fortunately the scientific method seems to be stronger that individuals' biases.

Well, he was a little too enthusiastic and quite close to claiming that.

There are really many types of chancer, and Vitamin C (if confirmed) seems to help only from some types of it.

So that he died of cancer say absolutely nothing about Vitamin C.

It certainly says that vitamin C doesn't cure all cancers.

Right, but almost all cancers depend on this pathway. GLUT receptor mega overexpression is a milestone in cancer evolution and vitamin C in its oxidized form competes with glucose which is in cancer cells almost exclusive energy source.

If you live long enough, you have a really good chance of getting some type of cancer.

Really because I heard that once you get past a certain age, let's say 65, your chance of getting cancer goes way down.
Re:Vitamin C kills tumor cells with hard-to-treat mutation i... by matznerd on Monday November 09, 2015 @02:10PM (#10535082)
It's not that the cancer chance goes down significantly, it's that the highest risk for death after 65-75 is cardiovascular related.

When you hear something about a field you know very little about, your default reaction should be skepticism. People say bullshit stuff all the time and pass it off as fact.

I don't know much about cancer biology, but what you heard sounds wrong. I don't see why, as you live longer, your body gets better at fighting cancer. If anything, the opposite sounds more likely.

One possibility is that someone is citing data with survivorship bias. That is, the people who make it past 65 have good genes that generally lower their chances of getting cancer. Even if this were the case, obviously it doesn't imply a causal relationship where passing 65 years reduces your chance of getting cancer.

Flip 5 coins and stop when each turns up tails, record the number of trials until the last coin is tails (just use # trials for the last coin...). Repeat this 100 times. Does the probability of ending on a given trial keep increasing with trial#? No, it will peak depending on the number of coins and probability of tails for each coin (here always close to 0.5).

This is the same as accumulating n number of modifications in a cell until it grows into and gets detected as a tumor. Instead of accumulating "tails" you are accumulating mutations or whatever it turns out to be.

Not sure why this was downvoted... It is easy to prove to yourself. Here is some R:

#p=Prob(tails), n=# Coins, q=Prob(heads), Npop=# times to repeat

p=.5; n=5; q=1-p; Npop=1000

#Flip one Coin 100x and find first tails (probability of getting one mutation)

OneCoin=function() which(sample(0:1,100, prob=c(q,p), replace=T)==1)[1]

#Flip n coins and find last one to turn up tails (probability of accumulating n mutations)

OneSet=function() max(replicate(n,OneCoin()))

#Repeat Npop times, like different people in a population

res=replicate(Npop,OneSet())

hist(res, breaks=Npop/20)

Not if you really do live long enough: "4% of centenarians die of cancer, compared to almost 40% mortality in the middle-age group"

But he was in his 90's. Really, the only way to test if it worked is to make him relive his life without vitamin C :-)

A lot of people advocate cannabis as a cure for cancer.

I remind them that Bob Marley died from cancer.
