I’m neither for or against these differing points of view that I’ve listed, I’m just interested in finding some clarification as to whether or not the supporting claims have any merit, and also if there’s anything else out there on the fringe that might be considered challenging to curent methodology that is worthy of discussion.
The information denouncing “excessive” dietary fibre comes mostly from Konstantin Monastyrsky’s website. One claim he makes is that:
“Chapter 10, Colon Cancer cites studies that demonstrate the connection between increased fiber consumption and colon cancer. Also, countries with the highest and lowest consumption of meat are compared. Not surprisingly, the countries with the lowest consumption of meat and, correspondingly, the highest consumption of carbohydrates, including fiber, have the highest rate of digestive cancers, particularly of the stomach.”
As for feeding frequency I recently came across a reference to a study relating the correlation between feeding frequency and colon cancer:
At the University of North Carolina, researchers studied six hundred thirty-six participants with colon cancer and 1,048 control participants. Eating frequency was categorized as fewer than three, three or four, or more than four meals a day.
"At the University of North Carolina, researchers studied six hundred thirty-six participants with colon cancer and 1,048 control participants. Eating frequency was categorized as fewer than three, three or four, or more than four meals a day.
“The researchers found that the effect of eating frequency on colon cancer differed by sex. The male participants in the lowest eating frequency group had approximately half the risk of colon cancer compared with the middle and highest group. And, there were no significant associations for women. So eating three meals a day was associated with a lower risk of colon cancer for men but not for women.”
Inconclusive I suppose if their diets were not controlled.[/quote]
Neither study means anything.
In the country comparison study, it’s irrational to point out fiber as the culprit when who knows how many other factors might be responsible.
For example, say those countries with lower protein, higher carb, and higher fiber intake are Asian countries. Who’s to say it’s not the soy sauce causing the stomach cancer? (such a link has long ago been proposed)
Sounds to me like Konstantin has no clue about research, picks one epidemiological study that does NOT even support his conclusion (he’s overgeneralizing), and ignores all the studies about higher colon cancer rates in the US correlating with low vegetable intake.
We learn little from the second study because what were those men eating for meals 4, 5, or 6? How many non-bodybuilders eat so many meals? They may have been morbidly obese men who stop at Dunkin Donuts a couple times a day, and have a big milkshake at bedtime.
