This came up on a UK low carb forum I participate in. All the study actually
showed was that the way data is collected (via questionaires) may mask a
relationship between dietary fat and breast cancer. ( Also, note that nobody is
mentioning high fat (or high saturated fat) diets in the context of a low-carb
diet. Certainly one cannot eat all the carbs/sugars one wants and then glop on
blobs of fat and expect this to be a healthy dietary regime. What has been
demonstrated is that cancer feeds off of glucose. Carbs provide glucose. This
is why very high fat ketogenic diets have been used to shrink tumors. Cites
to these studies have been posted before on this forum -- just do a search.)
The article writer in the New Zealand Hearald just put his/her own
sensationalized (or rather fictionalized) spin on what the actual study results said.
Below is a direct quote from the actual study result's intro.
'Measurement error of diet is a major problem when examining associations
between diet and disease endpoints such as cancer'
"Is there a link between fat intake and breast cancer? Although pooled
analyses of cohort studies indicate that no association exists, Sheila
Bingham and colleagues suggest that food-frequency questionnaires (FFQ) used
in these studies are prone to error. The researchers noted that the risk of
cancer was associated with saturated-fat intake measured with a 7-day food
diary, but not with saturated fat measured with the FFQ. The investigators
concluded that errors in measurement of dietary intake might explain the
absence of a significant relation between fat intake and breast cancer risk
in cohort studies. In a Commentary, Ross Prentice explains that use of
biomarkers of nutrient consumption could potentially reduce measurement
error in dietary self-reporting, although few such biomarkers exist."
