If I had to bet, it would be on HPV causing a majority of the rise in colorectal cancer. It is a major cause of throat cancer in men[0] and causes almost 100% of cervical cancer in women[1]. We have had a significant increase in anal sex over the past 10+ years[2] and are now seeing an increase in colorectal cancer.

"Britain has found that the proportion of 16- to 24-year-olds engaging in heterosexual anal intercourse has risen from 12.5% to 28.5% over recent decades. Similarly, in the US 30% to 45% of both sexes have experienced it."

Still needs to be studied more as there don't seem to be any large studies yet.

"We found that colorectal tissues from 28 (51%) of 55 patients with colorectal cancer were positive for HPV DNA." [3]

Ironic that the other trending HN post is "EU-banned pesticides found in rice, tea and spices"

What I find interesting is the concept of dead food versus live food. This is just something I wonder about. For example a dead apple is one that was picked a year ago, sold today, kept in storage until now. Long shelf life - is the crucial change in our eating that I can see. When was the last time you had a fresh apple? Does the food industry want us to consider the health benefits of a dead apple versus a living apple?

Let think twinkies! You can open a package of twinkies and let it sit out for a long time. A long time. A long, long time. They you can eat it. Long shelf life means it does not succumb to digestion by random microbes etc in the environment. Does the twinkie then succumb to the random microbes in your gut? I think not, but what do I know.

Then there is living food. You can take milk, put a culture in it and let it grow for 10 hours. Instant pot, heating pad, whatever. Then you eat it. It is now filled with living cultures. It tastes better to me than any store bought yogurt, costs exactly the same as the same quantity of milk. With a chopped apple, cinnamon and a tiny bit of sugar it tastes better to me that most of the faux ice cream you get these days.

What is funny to me is the conversations we have about "ultra processed food" do no address this aspect of the issue. I keep wondering why.

Stick to the science folks. Let the MDs do what they do.

Stats and population level studies are hard work. You need to vote somebody in who will support this, or live with the consequences.

Obesity. Being overweight is directly correlated with an increased risk for over a dozen cancers. And people are fatter than ever.

That and forever chemicals and plastics used in food shipping, storage, and cooking.

Those are my two best guesses.

The air we breathe is one of the most overlooked things IMO. There's so many toxins especially in cities. If your apartment is unventilated or the ventilation has no filters get a high airflow air purifier now.

Poor diet seems most likely. In particular too much focus on protein and not enough fibre.

Most people get enough protein but only 5% of Americans get enough fibre in their diet.

No till farming is probably helping. I learned this year what that really means by seeing farms where they spray herbicide to kill the plants,then they plant new seed while the old dead is still standing around. They then use herbicide as a desiccant to kill the plant at harvest. They probably use pesticides too. The cycle then repeats. I was so disgusted as seeing new crops sprouting amongst the dead vegetation. It must be engineered for that. I came to the inescapable conclusion that the farmers are poisoning everyone rather than have to offer real jobs to native born laborers.

Buckets of *cide, herb and insect, through the cycle. Those no till fields full of crops are some of the most disgusting things I have ever seen. That soil will have applications and applications of *cide soaked in it top to bottom. Like eating plants from a toxic waste dump.

Disgusting. That's the critical national need for glycosphate. Feeding us all engineered stuff from toxic waste dumps so farmers can not need workers or mowing and tilling equipment.

Could it be the plastics, or maybe the pollution in the air, or maybe the pfas in the water, or maybe the pesticides in the food, or maybe the vaping, or maybe the sedentary lifestyle, or maybe the hundreds of nuclear weapons exploded all over the earth, or maybe it’s the degradation of the ozone layer due to chemicals used in manufacturing.

Such a mystery.

Are more young people getting cancer? How much? What kinds?
moi238832分前
Well, what if it’s not a single cause, but a combination of

- older parents

- higher bmi

- processed food

- pesticides

- less exercise

- more stress

- hpv

- air quality

- pfas

- lack of sleep

for millions of years we were constantly fasting, then we hunted and killed animals, eating their protein and fat, no carbs, we were constantly in ketosis

We recently begun eating carbs, And very very recently started eating tons of processed carbs (because now we got the tech)

We are rarely in ketosis, and because of high carbs/sugar consumption, we start developing insulin resistance. (the idea is simple, we create resistance for most drugs/substances we take, be it anti depressants, caffeine, nicotine and so on.. the same happens with insulin. each time you eat too much sugar, your pancreas needs to issue insulin, so your cells can absorb more sugar. they start being resistant to it, so your pancreas need to work stronger and issue more and more insulin)

insulin is oxidative and inflammatory. we simply weren't built to regulate our blood sugar levels down (we are only equipped with insulin to do so), we are more well equipped to spike glucose levels up (gluconeogenesis, glucagon, cortisol and so on...)

because we are rarely in ketosis, we rarely get into the autophagy state (which is the auto-recycling cell system). so our cells multiply and the most error prone structure is the mitochondria.

mitochondria can make energy either from glucose or fat(keto bodies). it will always prefer glucose, only fallback to keto bodies (fat) when there is no glucose available. the synthesis of ATP (energy) from keto bodies will need oxygen as input, and will yield water as output. if we have inflammation, there is no oxygen (that's why severe chronic inflammation can lead to cancer), also that's why we usually use ice when we hurt ourselves, that place is inflamed, and by putting ice on it, it will change temperature (which changes pressure) and boosts blood circulation, blood carries oxygen, oxygen helps with inflammation.

a cancer cell, with a problematic mitochondria, will not be able to metabolize fat(keto bodies), because it has a problematic carburetor. fact is that the PET scans look for high glucose metabolism places in your body, because the cancer cells are starving for glucose.

the cell DNA is like ECC memory, it has self correction, but the mitochondria lacks the self correction, so it's way simpler to have it gone bad.

every single day we are having tons of cancer cells in our bodies, which self destruct or are detected and destroyed by our immune system.

the Middle East is the region in the world with the least cancer rate in the globe, yet they are one of the top consumers of sugar. but in islam they do the ramadan, in which for one month they make intermittent fasting basically, which boosts autophagy.

anyway... do healthy keto, boost autophagy, avoid ultra processed foods.

actually, I will extend this a little bit more... if you want to enter in keto...

go to the grocery store and buy this:

- meat (ground meat is fine and easy to prepare) - eggs (the most fresh ones if possible) - broccoli - butter or extra virgin olive oil

the portions will depend on your body type and so on.. but you would make meat and eggs on either butter and extra virgin olive oil, salt and pepper, and steamed broccoli. in my case it was 250g of ground meat, 4-5 eggs and one whole broccoli.

you must eat the broccoli first (it's fiber, you can't actually use it, the bacteria in your stomach does, it will make them very happy). if you eat meat+eggs first, you will feel full and will not be able to eat the broccoli, if you eat broccoli first, you will not feel full at all. use salt and pepper and olive oil.

eat the whole broccoli, that's like an ETF of micronutrients, it's very diversified!

then eat eggs+meat no problem...

you gonna feel very very full... do not eat any sugar/carbs.. it can take up to 3 days for entering in ketosis..

you can eat 2 to 3 times a day, eat only when you are genuinely hungry (your hunger will change drastically on how it's built over time)

then slowly entering in ketosis..

the rationale is that you need to cut off the garbage.. meat has high quality protein and fat, so does eggs (an egg has everything needed to begin a freaking life, fun fact: no carbs/sugar in it...)

and the broccoli has micronutrients and make your gut bacteria happy.

the quality of those 3 foods will depend on some things..

for the broccoli, it's the soil... is it contaminated or not? where did it grow?

for the eggs, is the chicken healthy? did she get sun? did she eat insects, worms, or just genetic modified ration?

same for the cattle...

but you are limiting a lot the potential contaminations sources..
