Vitamin A consumption predicts smoking patterns in this study
Vitamin A, β-Carotene, and the Risk of Cancer: A Prospective Study
Abstract
A cohort of 10,473 residents of Leisure World, Laguna Hills, CA, who were initially free of cancer were followed from 1981 to 1986. A health survey questionnaire completed by all cohort members included usual frequencies of consumption of certain food items, including vegetables, fruits, dairy products, liver, and cereal, as well as specific information on brand and formulation of vitamin supplements containing vitamins A, C, or E. Pathologic diagnosis of incident cancer was confirmed in 643 persons (56 lung, 110 colon, 59 bladder, 93 prostate, 123 female breast, and 202 cancers of other sites). Our study found little indication that increased intake of vitamin A or β-carotene from the diet or supplements protects against the development of cancer overall. Dietary vitamin A intake was highly associated with smoking status; 25% of current smokers were in the highest third of dietary vitamin A consumption versus 32% of past smokers and 36% of never-smokers. In males who never smoked there was some indication that cancer rates decreased with increasing vitamin A intake, but the results were not statistically significant.
So smokers choose a diet that is lower in VA than non smokers? Smoking destroys VA so it would then be expected that smokers on average suffer from less high VA issues.
Working within the "poisoning for profits" paradigm, I've been quite suspicious about the war on smoking for some time. While it would be ridiculous to deny that smoking has negative health effects, those of us that are aware of just how many assaults on our health are condoned by authority can see that the scale that smoking is being targeted is out of all proportion to its risks.
It doesn't sit well with me that it is all about it being a convenient scapegoat to blame disease on. If it was that then why would they be taking such an aggressive approach to eradicating smoking completely from the West?
Centuries ago in London during the Plague school teachers forced children to smoke each day in an effort to reduce the chance of infection. Perhaps it does make infection more difficult and a virus is being prepared for population reduction and smoking might interfere with its effects?
Or maybe smoking interferes with VA poisoning for profits?

"25% of current smokers were in the highest third of dietary vitamin A consumption."
Smokers habitually consumed more vitamin A according to this study. I think it is actually that people who consume a lot of high Vitamin A foods are more likely to smoke because cigarette smoke destroys the Vitamin A in all it's forms, while typically not affecting Vitamin E status or damaging any of the lipids.
I agree with you. The whole reason I got into this diet is because I took up smoking at a late age, and found it relieved many issues. Smoking completely and reliably eliminated my brain fog. Since reducing Vitamin A from my diet last summer, I stopped smoking cigarettes. I have very little desire to smoke. And when I did have a cigarette socially, it didn't have that same relieving effect. It was just mildly stimulating. I think the rise of tobacco, alcohol, and coffee/tea is partly in response to a diet that is far higher in preformed vitamin A than is natural. It is probably why French people remain healthy while eating butter, pate, fatty cheeses, fatty fish. No one dares to even bring up the smoking habits as perhaps having something to do with it.
I read the study to say that 36% of never smokers were in the highest third and 25% of current smokers were?
Interesting observations.
I have always enjoyed smoking (I have a smoke when I feel like it, not addicted) especially with alcohol. I also really like smoky environments like bonfires and incense which probably lowers retinol as well.
Modern humans are the first people to not have any exposure to smoke since humans learnt to harness fire. In the middle ages only the poorest drank water, everyone else drank some form of alcohol throughout the day which would have also reduced retinol levels. Modern humans are also the first humans not to harbour intestinal worms like hookworms which lower iron and retinol levels. Just one old world hookworm drinks 0.2ml of blood per day. Blood letting with leeches and venesection was also very popular. We also don't suffer from infectious disease anymore in the West which dramatically depletes retinol levels. We can't forget the contribution of all the new weird chemicals like glyphosate that can mess up retinol metabolism. Europeans ate plenty of dairy, eggs, liver and seafood in the past although they would have had a lot less carotene I think but it is easy to see why their diet didn't poison them so readily as it does us now.
Also being indoors and lacking sunlight and exercise which both reduce retinol levels doesn't help either.
Does anyone have any other factors I have missed?
