Buddha Pest - 24 Aug 2006 21:59 GMT I've been eating a daily slice of cheddar cheese lately. About 2 x 2 square slice (inches). I figure this would get my daily allotment of dairy products. But I am concerned about cholesterol, triglicerydes, etc.? How does this small amount of cheese affect that? I usually eat or drink no other dairy products whatsoever until I do the occasional pig-out of ice cream. Thanks.

Get blood work that is real then plug in different numbers. Want drugs? OK but look at what the numbers can mean.
Bon appetite.
Bill who reads carbs good to reduce and ice cream is fat and sugar last time I looked ;))

Dairy products don't cause dyslipidemia, especially if it's dairy from grass fed cows.
Starches and sugar cause dyslipidemia/metabolic syndrome.

Depends on how much is consumed. 3% is fat. There is also plenty of sugar (lactose). Most folks is ASD will attest to dairy products raising their blood glucose.
> Starches and sugar cause dyslipidemia/metabolic syndrome. Again, depends how much is being consumed and whether there is any visceral adiposity.
It is the visceral adipose tissue that is really the cause of metabolic syndrome (MetS).

A 2x2 square may be about an 1.5 oz. Saturated fat depresses LDL receptor levels and consequently raises circulating levels of LDL. Ice cream has even higher levels of saturated fat (in the range of 14-24 grams per serving). So both are potentially bad. Most people feel you should keep your saturated fat intake to less than 7% of daily calorie intake (about 14 grams total for a 2000 calorie per day diet). Eat low fat yogurt & similar products as a much better source of dairy (beneficial probiotics + dairy). In general for a heart friendly diet the best thing you could do is lower your consumption of saturated and trans fats and increase your consumption of monosaturated and add a small amounts of omega 3 fats.
For some references on saturated fat mechanism for raising LDL see for example

Find the studies that found this effect from alpine grass fed cows or grass fed beef anywhere, or from saturated fat in the absence of significant glycemic load.
Further, higher LDL is not a good CVD risk predictor, as compared to high TGL, caused by high glycemic load.

It also supported the contention that linolenic acid (a form of fat) is preventive against heart disease. (Ascherio A et. al. Dietary fat and risk of coronary heart disease in men: cohort follow up study in the United States. British Medical Journal, 1996 Jul 13, 313:7049, 84-90.)"
"Several studies have shown that high-carbohydrate low-fat diets lead to high triglycerides, elevated serum insulin levels, lower HDL cholesterol levels, and other factors known to raise the risk of coronary artery disease. (See Liu GC; Coulston AM; Reaven GM. Effect of high-carbohydrate low-fat diets on plasma glucose, insulin and lipid responses in hypertriglyceridemic humans. Metabolism, 1983 Aug, 32:8, 750-3.

"The idea that saturated fats cause heart disease is completely wrong, but the statement has been 'published' so many times over the last three or more decades that it is very difficult to convince people otherwise unless they are willing to take the time to read and learn what...produced the anti-saturated fat agenda." (Dr. Mary Enig, Consulting Editor to the Journal of the American College of Nutrition, President of the Maryland Nutritionists Association, and noted lipids researcher.)
"The diet-heart hypothesis [which suggests that high intake of saturated fat and cholesterol causes heart disease] has been repeatedly shown to be wrong, and yet, for complicated reasons of pride, profit and prejudice, the hypothesis continues to be exploited by scientists, fund-raising enterprises, food companies and even governmental agencies. The public is being deceived by the greatest health scam of the century." (Dr. George V. Mann, participating researcher in the Framingham study and author of CORONARY HEART DISEASE: THE DIETARY SENSE AND NONSENSE, Janus Publishing 1993.)
High intake of fats from the Omega-3 group increase HDL cholesterol, which is considered protective against heart disease. Obviously it would be difficult to eat an Omega-3 rich diet while following a traditional fat reduced diet, especially if one were following one of the popular American diets that has one eating only 20-30 grams of fat per day. (Franceschini G. et. al. Omega-3 fatty acids selectively raise high-density lipoprotein 2 levels in healthy volunteers. Metabolism, 1991 Dec, 40:12, 1283-6. See also Journal of the American College of Nutrition 1991:10(6);593-601)
A recent American study showed that low-fat, high-carbohydrate diets (15% protein, 60% carbohydrate, 25% fat) increase risk of heart disease in post-menopausal women over a higher fat, lower carbohydrate diet (15% protein, 40% carbohydrate, 45% fat). (Jeppeson, J., et. al. Effects of low-fat, high-carbohydrate diets on risk factors for ischemic heart disease in postmenopausal women. American Journal of Clinical Nutrition, 1997;65:1027-33)
The largest and most comprehensive study on diet and breast cancer to date, studying over 5,000 women between 1991 and 1994, showed that women with the lowest intake of dietary fat had a significantly higher incidence of breast cancer than the women with the highest intake of dietary fat. It also found that women with the highest intake of starch had a significantly higher incidence of breast cancer than the women with the lowest intake of starch. The study found no evidence that saturated fat had any effect one way or the other on breast cancer, and that unsaturated fat had a significantly protective effect against breast cancer. (Franceschi S et. al. Intake of macronutrients and risk of breast cancer. Lancet; 347(9012):1351-6 1996)
"The commonly-held belief that the best diet for prevention of coronary heart disease is a low saturated fat, low cholesterol diet is not supported by the available evidence from clinical trials. In primary preventions, such diets do not reduce the risk of myocardial infarction or coronary or all-cause mortality. Cost-benefit analyses of extensive primary prevention programmes, which are at present vigorously supported by governments, health departments, and health educationalists, are urgently required....Similarly, diets focused exclusively on reduction of saturated fats and cholesterol are relatively ineffective for secondary prevention and should be abandoned. There may be other effective diets for secondary prevention of coronary heart disease but these are not yet sufficiently well defined or adequately tested." (European Heart Journal, Volume 18, January 1997.)
"We found no evidence of a positive association between total dietary fat intake and the risk of breast cancer. There was no reduction in risk even among women whose energy intake from fat was less than 20 percent of total energy intake. In the context of the Western lifestyle, lowering the total intake of fat in midlife is unlikely to reduce the risk of breast cancer substantially." (Hunter, DJ et. al. Cohort studies of fat intake and the risk of breast cancer - A pooled analysis. New England Journal of Medicine, 334: (6) FEB 8 1996)
2) Title: DG-DISPATCH - ENDO 99: Diabetics Improve Health With Very High-Fat, Low Carb Diet Doctor's Guide June 15, 1999
By Cameron Johnston Special to DG News
SAN DIEGO, CA -- June 15, 1999 -- A very high-fat, low-carbohydrate diet has been shown to have astounding effects in helping type 2 diabetics lose weight and improve their blood lipid profiles.
The results of three studies involving such a diet, which is similar to, but has a few key differences from the famous "Dr. Atkins Diet", were presented today at the annual meeting of the Endocrine Society.
Dr. James Hays, an endocrinologist and director of the Limestone Medical Center in Wilmington, DE, admitted that the concept of a high-fat diet in people who are already at higher risk of cardiovascular disease might seem incongruous. Nonetheless, this study of 157 men and women with type 2 diabetes showed an impressive benefit in body mass index (BMI) triglycerides, HDL, LDL and HbA1c.
Most people are encouraged to reduce the amount of fat in their diets, particularly saturated fats, and diabetics in particular are advised to reduce their overall caloric intake, Dr. Hays explained in an interview in San Diego during the conference.
Whereas a normal diet would be in the order of 1800 to 2100 calories, with 60 percent of calories coming from carbohydrates and 30 percent from fat, patients
in this diet were restricted to 1800 calories per day and were encouraged to get 50 percent of their caloric intake from fat, and just 20 percent from carbohydrates. The balance of 30 percent would come from proteins.
A whopping 90 percent of the fat content in their diets was saturated fat, compared with just 10 percent that was monounsaturated fat.
"I think this is at least worth considering for any diabetic," Dr. Hays said in an interview. "The thing many diabetics coming into the office don't realize is that other forms of carbohydrates will increase their sugars, too. Dietitians will point them toward complex carbohydrates ... oatmeal and whole wheat bread, but we have to deliver the message that these are carbohydrates that increase blood sugars, too."
Higher-fat diets, on the other hand, seem to make the person feel full faster so they eat less; higher-fat diets also tend to reduce postprandial hypoglycemia so the patients feel better after eating.
"Every diabetic comes home from the doctor with instructions as to what their diet should consist of, but they're not getting the information from dietitians about what complex carbohydrates they should eat,"
Dr. Hays said: "The important thing here is no ketosis. We absolutely don't want people to become ketotic, and so we said they had to have so many exchanges of fresh fruits and vegetables and we specified the ones they could eat."
They were able to eat all the meat and cheese they wanted, but as for carbohydrates, they are restricted to eating unprocessed foods, mainly fresh fruit and vegetables, he added.
Subjects recruited into the study (84 men, 73 women) were all type 2 diabetics and were required to undergo a standard American Diabetes Association modified diet for one full year before entry into the trial. Over the course of one year, the subjects achieved a mean decline in total cholesterol of between 231 and 190 mg/dl. Triglycerides declined from 229 to 182 mg/dl.
Low-density lipoproteins (LDL cholesterol) fell from 133 to 105 mg/dl, while HDL increased from 44 to 47 mg/dl.
HbA1c, which at the start of the study averaged 3.34 percent above normal, declined to the point that at one year, the mean was just 0.96 percent above normal.
The average weight loss among subjects in the study was in the order of 40 pounds, Dr. Hays said.
By the end of the one-year study, he added, 90 percent of the patients had achieved ADA (American Diabetes Association) targets for HbA1c, HDL, LDL and triglycerides.
Even among juvenile diabetics, he said, they might not be overweight and they might have more or less normal lipid levels, but when they are on this kind of diet it is possible to treat them with lower doses of insulin and make their lives a little safer, he said.
As for the response from cardiologists who see a high-fat diet as anathema to what they have been instructing their patients for years now, Dr. Hays said he has three cardiologist patients who are now on the diet.
"If you have a diet that results in weight loss, lower cholesterol, and a better lipid profile, eventually, everybody will be eating that way. It's going to come whether we like it or not."

Dietary Fat Intake and the Risk of Coronary Heart Disease in Women Frank B. Hu, Meir J. Stampfer, JoAnn E. Manson, Eric Rimm, Graham A. Colditz, Bernard A. Rosner, Charles H. Hennekens, Walter C. Willett ------------------------------------------------------------------------- -------
Abstract Background. The relation between dietary intake of specific types of fat, particularly trans unsaturated fat, and the risk of coronary disease remains unclear. We therefore studied this relation in women enrolled in the Nurses' Health Study.
Methods. We prospectively studied 80,082 women who were 34 to 59 years of age and had no known coronary disease, stroke, cancer, hypercholesterolemia, or diabetes in 1980. Information on diet was obtained at base line and updated during follow-up by means of validated questionnaires. During 14 years of follow-up, we documented 939 cases of nonfatal myocardial infarction or death from coronary heart disease. Multivariate analyses included age, smoking status, total energy intake, dietary cholesterol intake, percentages of energy obtained from protein and specific types of fat, and other risk factors.
Results. Each increase of 5 percent of energy intake from saturated fat, as compared with equivalent energy intake from carbohydrates, was associated with a 17 percent increase in the risk of coronary disease (relative risk, 1.17; 95 percent confidence interval, 0.97 to 1.41; P = 0.10). As compared with equivalent energy from carbohydrates, the relative risk for a 2 percent increment in energy intake from trans unsaturated fat was 1.93 (95 percent confidence interval, 1.43 to 2.61; P<0.001); that for a 5 percent increment in energy from monounsaturated fat was 0.81 (95 percent confidence interval, 0.65 to 1.00; P = 0.05); and that for a 5 percent increment in energy from polyunsaturated fat was 0.62 (95 percent confidence interval, 0.46 to 0.85; P = 0.003). Total fat intake was not significantly related to the risk of coronary disease (for a 5 percent increase in energy from fat, the relative risk was 1.02; 95 percent confidence interval, 0.97 to 1.07; P = 0.55). We estimated that the replacement of 5 percent of energy from saturated fat with energy from unsaturated fats would reduce risk by 42 percent (95 percent confidence interval, 23 to 56; P<0.001) and that the replacement of 2 percent of energy from trans fat with energy from unhydrogenated, unsaturated fats would reduce risk by 53 percent (95 percent confidence interval, 34 to 67; P<0.001).
Conclusions. Our findings suggest that replacing saturated and trans unsaturated fats with unhydrogenated monounsaturated and polyunsaturated fats is more effective in preventing coronary heart disease in women than reducing overall fat intake. (N Engl J Med 1997;337:1491-9.)

Metabolic risk factors worsen continuously across the spectrum of nondiabetic glucose tolerance. The Framingham Offspring Study.
Meigs JB, Nathan DM, Wilson PW, Cupples LA, Singer DE Massachusetts General Hospital, Harvard Medical School, Boston University School of Public Health, 02114, USA. jmeigs@sol.mgh.harvard.edu
BACKGROUND: Categorical definitions for glucose intolerance imply that risk thresholds exist, but metabolic risk for type 2 diabetes mellitus or cardiovascular disease may increase continuously as glucose intolerance increases. OBJECTIVE: To examine the distributions of the following metabolic risk factors across the spectrum of glucose tolerance: overall and central obesity, hypertension, low levels of high-density lipoprotein cholesterol, and increased triglyceride and insulin levels. DESIGN: Cross-sectional analysis. SETTING: The community-based Framingham Offspring Study. PARTICIPANTS: 2583 adults without previously diagnosed diabetes. MEASUREMENTS: Clinical data; fasting glucose, insulin, and lipid levels; and glucose and insulin levels taken 2 hours after oral challenge were collected from 1991 to 1993. Glucose tolerance was determined by 1980 World Health Organization criteria. Patients with normal glucose tolerance were categorized into quintiles of fasting glucose. The distributions of each metabolic risk factor and the metabolic sum of the six risk factors were assessed across seven categories from the lowest quintile of normal fasting glucose level through impaired glucose tolerance and previously undiagnosed diabetes. RESULTS: The mean age of patients was 54 years (range, 26 to 82 years); 52.7% of patients were women. Glucose tolerance testing found that 12.7% of patients had impaired glucose tolerance and 4.8% had previously undiagnosed diabetes. Multivariable-adjusted mean measures of risk factors and odds ratios for obesity, elevated waist-to-hip ratio, hypertension, low levels of high-density lipoprotein cholesterol, elevated triglyceride levels, and hyperinsulinemia showed continuous increases across the spectrum of nondiabetic glucose tolerance. Although a threshold effect near the upper range of nondiabetic glucose tolerance could not be ruled out for triglyceride levels in men and for insulin levels 2 hours after oral challenge in men and women, no other metabolic risk factors showed clear evidence of thresholds for increased risk. CONCLUSIONS: Metabolic risk factors for type 2 diabetes mellitus and for cardiovascular disease worsen continuously across the spectrum of glucose tolerance categories, beginning in the lowest quintiles of normal fasting glucose level.

Yabbut, can you find a single paper that has good objective evidence of a role for saturated fat in causing CVD? That would require controlling for the powerful hormonal.inflammatory/atherogenic effects of carbohydrate in the diet. A good study would examine the role of fat in the absence of significant glycecmic load.
Otherwise, it's pure crapola.

"Indeed, physical inactivity combined with an atherogenic diet (rich in saturated fat, trans fatty acids and refined sugars) constitute the perfect combination giving rise to the metabolic syndrome. These lifestyle variables, acting either through obesity or insulin sensitivity, disturb the metabolic homeostasis and lead to the multiplex risk factors."

This is an example of the kind of either/or black/white/no greys not ever sh.t that pisses me off. IR leads to obesity, then the fat cells signal to the body in a way to sustain the obesity, and contribute to IR. It's not one or the other; it's BOTH.

I'm talking about a single study that shows that consuming more saturated fat rather than (preferably) a number of other things causes the rate of disease and death to rise.
Much of the older work I've read so far was done without understanding of the effects of trans-fats. Usually, studies decreased saturated fat while decreasing trans-fat and then attributed the reduced disease to reduction of the sat-fat.
I don't have a firm opinion on the truth of the matter, BTW. That's why I'm interested in finding any good studies that speak directly to the issue. -- Jim Chinnis Warrenton, Virginia, USA

The study that seems to have convinced researchers that saturated fat was implicated in raising overall mortality and coronary artery disease in particular was reported in 1972 in Finland. It was a large well-done study IMO in nearly all respects. The study was done in two mental hospitals. The patients in one were placed on a modified diet designed to reduce serum cholesterol. After six years the hospital diets were switched. The investigators looked at the morbidity and mortality data. They also studied the fatty acid content of the patients' fat.
The diet was very effective in lowering heart disease and heart disease and overall mortality.
The diet consisted of the normal diet, but with a few substitutions. Ordinary milk was replaced by an emulsion of soybean oil in skim milk, and butter and stick margarine were replaced with a soft margarine high in polyunsaturates.
So....there were several changes. The cholesterol-lowering diet reduced saturated fats, reduced trans-fats, and increased a broad range of polyunsaturates (including short-chain omega-3).
One obviously can debate whether the benefit was due to sat fat reduction, trans-fat reduction, or supplementing with ALA. Yet this large randomized study seems to me to be the primary argument for an observed link between sat fat and morbidity and mortality. At the time the study was reported, the Lyon study was more than 20 years away, and knowledge of effects of trans fats was negligible. -- Jim Chinnis Warrenton, Virginia, USA

What's unethical is for the AHA and the ADA to keep promoting the high glycemic diet that is now proven to promote heart disease and diabetes.
Since low fat diets raise TGL, HbA1C and lower HDL, they are the unethical choices:

Low-fat diets do not lower plasma cholesterol levels in healthy men compared to high-fat diets with similar fatty acid composition at constant caloric intake.
Nelson GJ, Schmidt PC, Kelley DS.
Western Human Nutrition Research Center, USDA, ARS, Presidio of San Francisco, California 94129, USA.
In most studies reporting the effects of high-fat (HF) and low-fat (LF) diets on human plasma fatty acids (FA) and lipoprotein levels, the design involved adding to the diet an oil that had an FA composition (FAC) very different from the FAC of the control diet. Thus, it is difficult to determine if simply reducing the fat content of the diet without changing the dietary FAC changes the tissue FAC or alters plasma lipid levels. In this study, we fed diets that contained either 22 or 39% of calories from fat, but had no differences in their FAC, for 50 d to a group (n = 11) of healthy men (20-35 y). Thus, the polyunsaturated/saturated ratios (1.0) of the diets were identical as were the n-3/n-6 ratio and the monounsaturated-to-total fat ratios. The diets contained (wt% of total fat) approximately 28% saturated FA, 33% monounsaturated cis-FA, 6% monounsaturated trans-FA, 22% n-6 polyunsaturated FA, and 7% n-3 polyunsaturated FA, and 4% other minor FA. The diets consisted of natural foods and were formulated to contain 16 en% protein, either 45 or 62 en% carbohydrate (CHO) and at least the recommended daily allowance for all micronutrients. Both diets contained 360 mg of cholesterol per day. All subjects were given the HF diet for 20 d, and then six were placed on the LF and the other five remained on the HF diet for 50 d. The two groups were crossed-over for the remaining 50 d of the study. The subjects' baseline total cholesterol level was 173 mg/dl, after 50 d on the HF diet it was 177 mg/dl and after 50 d on the LF diet, 173 mg/dl. The differences were not significant, and there were no significant changes in either the LDL or HDL cholesterol levels with either diet. Triglyceride levels, and consequently very low density lipoprotein levels, rose significantly on the LF, higher CHO diet compared to the levels found in the subjects on the HF diet (91.5 and 66.4 mg/dl respectively, P < 0.002). The linoleic acid content of the plasma, platelets, and red blood cells was significantly (P < 0.05) reduced in the LF diet compared to HF diet, without any obvious physiological effects. Hence, many earlier observations indicating reductions in plasma lipid levels when people are on LF diets may be due to changes in the FAC of the diet, not the reduction in fat calories.

J Am Coll Cardiol. 2006 Aug 15;48(4):715-20. Consumption of saturated fat impairs the anti-inflammatory properties of high-density lipoproteins and endothelial function. Nicholls SJ, Lundman P, Harmer JA, Cutri B, Griffiths KA, Rye KA, Barter PJ, Celermajer DS. The Heart Research Institute, Sydney, Australia; Department of Medicine, University of Adelaide, Adelaide, Australia.
OBJECTIVES: The purpose of this study was to investigate the influence of dietary fatty acids on the anti-inflammatory properties of high-density lipoproteins (HDL) and vascular function. BACKGROUND: The effect of dietary fatty acids on atherogenesis remains uncertain. METHODS: Fourteen adults consumed an isocaloric meal containing either a polyunsaturated or a saturated fat on 2 occasions. The effects of post-prandial HDL on endothelial cell expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) were determined. Flow-mediated dilation (FMD) and microvascular reactivity were assessed before and 3 and 6 h after the meal. RESULTS: Plasma triglycerides, insulin, and nonesterified fatty acids rose after the meals. The HDL collected 6 h after the saturated meal were less effective than HDL isolated from fasting plasma in terms of their ability to inhibit expression of ICAM-1 and VCAM-1, whereas HDL collected 6 h after the polyunsaturated meal had an inhibitory activity that was greater than that of HDL collected from fasting plasma (p < 0.004 and p = 0.01 for comparison of effect of meals on ICAM-1 and VCAM-1, respectively). Post-hyperemic microvascular flow significantly increased at 3 h after the polyunsaturated meal by 45 +/- 14% and by 21 +/- 11% after the saturated meal. The FMD decreased 3 h after the saturated meal by 2.2 +/- 0.9% (p< 0.05 compared with baseline) and by 0.9 +/- 1% after the polyunsaturated meal. CONCLUSIONS: Consumption of a saturated fat reduces the anti-inflammatory potential of HDL and impairs arterial endothelial function. In contrast, the anti-inflammatory activity of HDL improves after consumption of polyunsaturated fat. These findings highlight novel mechanisms by which different dietary fatty acids may influence key atherogenic processes. PMID: 16904539

Department of Geriatrics, Center for Lipoprotein Metabolism, University of Bari Policlinico, Piazza G. Cesare, 11-70124 Bari, Italy.
Recent evidence suggested a protective role of dietary monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) intakes against several chronic diseases and, therefore, an increased human longevity. After a median follow-up of 8.5 years, we investigated the possible role of MUFA, PUFA, and other selected food groups in protecting against all-causes mortality in a population-based, prospective study, conducted in one of the eight centers of the Italian Longitudinal Study on Aging (ILSA), Casamassima, Bari, Italy. Out of 704 elderly subjects (65-84 years), 278 nondemented persons agreed to participate at the first survey (1992-1993). During the follow-up, there were 91 deaths. A semi-quantitative food frequency questionnaire evaluating macronutrient daily intakes were performed at the first survey. Higher MUFA intake was associated with an increase of survival (hazard ratio 0.81, 95% CI 0.66-0.99), a higher unsaturated fatty acids (UFA) to SFA ratio (hazard ratio 1.20, 95% CI 0.99-1.45) increased total mortality only marginally, while no effect about other selected food groups were found. In conclusion, in this prospective study on older nondemented subjects with a typical Mediterranean diet, a higher MUFA intake increased survival, while a higher UFA/SFA ratio increased total mortality, but only marginally.

Consider the fact the in the American diet carbs are very refined whereas is Finland, where we live, they are not so often. Also, if I can draw proper conclusions, the epidemiological evidence shows that saturated fats are more harmful in Finland as there are fewer protective features in the local diet e.g. too little antioxidants and too little liquid vegetable oils (the intake of vegetable oils has increased during last decades).

> Jim Chinnis Warrenton, Virginia, USA I do not know if a study will every satisfy you. In the meantime for somebody with CAD this is a real time experiment - they can choose to act based on the best available evidence or choose to wait to be convinced while the disease progresses.
The reality is you can use surrogate endpoints like LDL reduction to argue for limiting saturated fat consumption. For example replacing 25 gram of saturated fat with monounsaturated fat is expected to decrease LDL by 15 mg/dL based on regression equation from several metanalysis. This corresponds to a 10% reduction in cardiac events over 5 years for a person starting with an initial LDL of around 150. The reality is somebody with established CAD needs very aggressive treatment if they hope to prevent the disease from advancing based on physical measurement of progression of the disease as several IVUS based studies have shown. The seemingly modest reduction in LDL may be quite important in helping people meet aggressive lipid lowering targets - assume a target of 60 mg/dL or less for LDL. This may need multiple drugs or the aid of prudent dietary measures to help meet the goal.
The modest LDL reduction would be even more beneficial for somebody who adopts this kind of strategy very young because it is clear that modest reductions for long periods of time are much more beneficial over long periods of time (See for example Brown and Godstein's opinion piece in Science 311, 1721-1723 - Lowering LDL - Not only how Low but how Long ?).
Similar arguments could be made for effects on endothelial function etc. I personally love cheese but certainly limit my intake and I am mindful of all saturated fat I consume. I do not think the entire scientific community is deluding themselves in thinking it is a bad player in CAD. For example, scientists had no problem showing very low fat diets did shift LDL patterns to more atherogenic forms etc. I.e. they are not as wedded to "dogma" as Susan seems to suggest from her posts.

Roland, you may be misunderstanding my point. I do reduce my intake of saturated fat based on what we know.
All the same, it seems to me that a good trial that relates sat fat to endpoints would be nice to have. That's why I've been reviewing the old literature that is always cited as evidence.
So far without success. -- Jim Chinnis Warrenton, Virginia, USA
David Rind - 27 Aug 2006 12:43 GMT > The reality is you can use surrogate endpoints like LDL reduction to > argue for limiting saturated fat consumption. I'm willing to grant that that is probably true for cardiac mortality, but not for overall mortality. We have relatively little evidence that interventions (other than statins) that reduce LDL lead to a reduction in all-cause mortality in people without known CHD. And even in people with known CHD, high-intensity statin regimens lower LDL more and reduce CHD events more than low-intensity statin regimens, but have no important effect on all-cause mortality.
So I'd be cautious about using LDL reduction as a surrogate for overall improved mortality outcomes. For instance, I'd really like to see a randomized trial showing that ezetimibe has some important benefit for a clinical endpoint rather than a chemical endpoint.

Round foods are healthy i.e. oranges, pomegranates, blueberries. Even broccoli, onions and carrots are round when looked from above. Foods lacking round shape promote illness, like meat, milk and bananas. BTW, many cheeses are round by their shapes and that is why they don't promote illness. Always remember to buy round shaped cheeses only!

Saturated fat depresses If we believe Serge Renaud, the originator and one of the authors of the Lyon Diet Heart Study, and why wouldn't we, cheese has never been associated with CHD:

Renaud's answer is simple. The participants in the Lyon study ate like Cretans: no butter, cream, or milk; lots of vegetables, fruit, bread, and cereals; and little meat. For the study, Renaud designed a margarine similar in composition to olive oil, but enriched in a-linolenic acid. Patients ate cheese (a 9000 year old invention not linked to coronary disease) and, of course, drank wine.
Cheese does not seem to affect serum lipis unfavorably:

"Background - Dietary fat is the major macronutrient that modifies lipids and lipoproteins. Saturated fat increases LDL, HDL with minimal effect on triglycerides. Part of the French Paradox is high intake of cheeses and low rates of CHD. The effect of cheeses on serum lipids has not been investigated. Method - 20 patients had baseline cholesterol, 4 week low fat (LF) diet (< 25% of calories as fat) followed by 4 week cheese diet (100g of camembert daily, 32-35% of calories of fat). Plasma Lipids were measured at baseline, after LF, and after cheese diet. Patients had dietary counseling at LF and cheese. Food intake was assessed by 3 day dietary diaries at the end of each diet period. Results - During LF compared to baseline, Total cholesterol, HDL and LDL (Friedewald calculation) dropped significantly (P=0.001, P=0.0001 and P=0.008). No other changes were detected. Conclusions - On the background of a LF diet, including cheese is not associated with adverse effects on serum lipids. Fermentation presumably is responsible for these favorable effects."

RESULTS: Fasting LDL cholesterol concentration was significantly higher after butter than cheese diet (p = 0.037), with a borderline significant difference in total cholesterol (p = 0.054) after the experimental periods of three weeks. Postprandial glucose showed a higher response after cheese diet than after milk diet (p = 0.010, diet x time interaction). CONCLUSIONS: A different effect of fat in milk and butter could not be confirmed in this study. The moderately lower LDL cholesterol after cheese diet compared to butter diet should be investigated further..."

That's an interesting study. It's hard to assess the potential effects of self-selection of the vegetarians and having the vegetarians pick the meat-eaters, though. -- Jim Chinnis Warrenton, Virginia, USA

Similarly, the vegetarians/vegans picked friends or associates in order to eliminate social/economic biases. But still...I doubt that vegans eat out as much. I suspect they make more of their meals from scratch. Being a "meat-eater" may well mean in large measure eating fish-and-chips, greasy factory-produced hamburger, washed down with colas.
I'm a passable statistician, but no amount of statistical expertise can sort out those kinds of things in a non-randomized study. -- Jim Chinnis Warrenton, Virginia, USA

A citation:
"... All subjects were volunteers. The vegetarian subjects were recruited through the Vegetarian Society of the United Kingdom, publicity in the national and local media, and word of mouth via subjects already recruited. Nonvegetarian subjects were recruited by the vegetarian subjects, who were asked to nominate friends and relatives of similar lifestyle and social class but who ate meat, fish, or both. ..."
Also, the death rate ratios for cheese were not statistically significant, although the trend was. Another peculiarity of this study: green vegetables were associated with non-significant increase in IHD mortality. I wonder whether refined grain products, potatoes or some other high glycemic foods would have been associated with significant increase in IHD mortality, if they had been researched. However, for some strange reason they were not investigated.

Eating cheese didn't seem to affect very unfavorably the participants of the Lyon Diet Heart Study: despite eating cheese their CHD event and mortality was reduced 70% in relation to control group.
