At last I know how these damaging and pernicious guidelines came
about. They introduced a dark age of medicine and dogma that continues to
effect my practice.
How I struggle to get patients to accept eggs and butter as part of a
healthy diet . It's my belief that sugar and other carbohydrates are the
real problem.
I have seen great results for 70 patients in my practice with the
metabolic syndrome using the low carbohydrate, higher fat diet for an
average of 13 months. Despite the eggs and butter their cholesterol levels
improved along with significant weight loss and improvements in diabetic
control.
When will the guidelines be re written to properly reflect what we
know about fats. All we seem to have at present is confusion
Hopefully the meta-analysis by Harcombe et al. (1) may inspire the
authorities to correct their dietary recommendations, because other
studies have shown that the intake of saturated fatty acids (SFA) does not
increase the risk of cardiovascular disease.

Hopefully the meta-analysis by Harcombe et al. (1) may inspire the
authorities to correct their dietary recommendations, because other
studies have shown that the intake of saturated fatty acids (SFA) does not
increase the risk of cardiovascular disease.
Not only did the authors of the dietary guideline from 1977 and 1983
ignore the dietary trials; they also ignored several unsupportive cohort
studies. Before 1977 three prospective population studies had shown no
significant difference of SFA intake between CHD patients and people free
of CHD, and in 1983 five more had been published and with the same result.
Together these studies included 1920 patients with CHD and 45615 without
(2).
Furthermore, numerous studies published since then have acquitted SFA
in various ways. Let me mention only a few of the most important ones.
Today more than 30 population studies have shown the same result as
mentioned above, and in seven of ten prospective cohort studies patients
with stroke had eaten less SFA than those without; in the other three, no
difference was seen (2). Dietary information is of course inaccurate. A
more reliable method is to analyse the short fatty acids 12:0-15:0 in the
fat cells, because their contents reflect the intake of SFA during the
preceding weeks or months. In three case-control studies of patients with
CHD and healthy controls no difference was found as regards the content of
these fatty acids; in two studies it was even significantly lower in the
patients. These studies concerned only patients with first myocardial
infarction or patients who were not on a diet, and a diet bias is
therefore unlikely (3).

The data is accumulating to show the adverse outcomes in critically
sick patients with persistently elevated troponins. An elegant study by
Amman et al (1) in 58 critically ill patients without acute coronary
syndromes concluded "Positive troponin levels were associated with higher
mortality (22.4% vs. 5.2%, p < 0.018) and a lower LVEF (p = 0.0006).
Troponin-positive patients had significantly higher median levels of tumor
necrosis factor (TNF)-alpha, its soluble receptor, and interleukin (IL)-6.
A subgroup of 10 aplastic patients was troponin-negative at study entry.
Three became troponin-positive during leukocyte recovery and subsequently
died, whereas all the others stayed troponin-negative and survived. Flow-
limiting coronary artery disease was not demonstrable at autopsy or stress
echocardiography in 72% of troponin-positive patients".
The results of the present study ( 2), if reproduced in larger
studies in patients with acute exacerbation of chronic obstructive
pulmonary disease; the future guidelines will include estimation and
trajectory of troponin for such patients to assess prognosis. Presently,
there is no way to influence the poor natural history of such patients
.However the future is to explore possible interventions to favourably
influence the natural history. The authors deserve congratulations for
their thought-provoking work.

The current dietary guidelines are strongly associated (at least
temporally) with an exponential growth in obesity and Type 2 diabetes.
These unintended consequences may have arisen due to increased consumption
of carbohydrate in order to reduce fat in the diet.

should be withdrawn and re-written. There is a precedent - we no longer

As a layman I feel I have been deceived by "lipophobic cardiologists"
and my food supply has been altered on the basis of false or missing
evidence. I am confronted by red traffic light labels on foods we have
eaten for centuries and I feel the establishment has lost the plot on this
one.
