Background: A reduction in dietary saturated fat has generally been thought to improve cardiovascular health.
Objective: The objective of this meta-analysis was to summarize the evidence related to the association of dietary saturated fat with risk of coronary heart disease (CHD), stroke, and cardiovascular disease (CVD; CHD inclusive of stroke) in prospective epidemiologic studies.
Design: Twenty-one studies identified by searching MEDLINE and EMBASE databases and secondary referencing qualified for inclusion in this study. A random-effects model was used to derive composite relative risk estimates for CHD, stroke, and CVD.
Results: During 523 y of follow-up of 347,747 subjects, 11,006 developed CHD or stroke. Intake of saturated fat was not associated with an increased risk of CHD, stroke, or CVD. The pooled relative risk estimates that compared extreme quantiles of saturated fat intake were 1.07 (95% CI: 0.96, 1.19; P = 0.22) for CHD, 0.81 (95% CI: 0.62, 1.05; P = 0.11) for stroke, and 1.00 (95% CI: 0.89, 1.11; P = 0.95) for CVD. Consideration of age, sex, and study quality did not change the results.
Conclusions: A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

I just recently went back to real butter and I season with bacon grease, if I die sooner, I’ll be happier before I die.
No surprise to me.
I’ve always thought that previous studies that showed a risk were rendered useless by lumping artificial trans fatty acids in the same category with natural saturated fats.
You’re better off just eliminating white flour and all sugar from your diet.
Once you do that it is amazing how much better other foods taste, and how much better you physically feel.
Carbs are converted to fat. That is why consuming a lot of sugar will make people fat.
In other words, all those “FAT FREE” label markings on sugary foods, are meaningless, and misleading.
why aren’t more cows dropping dead of heart attacks?
because they are dropping dead because we want to eat them
Butter not only tastes better than margarine, it melts at a lower temperature, is easier to digest, and one can use less to the same effect....yeah, less...HA!
Bacon fat and lard also melt at a lower temperature and taste better.
Real or not, like this study. Fits the “eat ‘right’ (some dispute here), stay fit, die anyway” paradigm.
Animal protein, butter, veg, fiber, some complex carbs....BGL looking pretty good. Your mileage may vary.
“There are many other causes including genetics, inflamation, bacteria, old age, etc. “
not getting enough omega 3’s may be part of it.
Why does it seem that my vegetarian friends seem to crave sugary things so bad? Could it be that too low of a fat or protein diet causes sugar cravings?
two words: Gertrude Baines
bacon and eggs !
Have a good french meal and - even with the small portions - you won’t be hungry until tomorrow.
Actually, the beef that we eat is mostly fed a mixture of corn and high carbohydrate grains. You can buy range-fed beef (cattle that eat grass only) and it is very lean; scarcely any fat at all. The last time I looked, range-fed ground beef was selling for about $6 a pound.
It is the high intake of cheap carbohydrates - refined sugar, potatoes, corn, most grains including rice; anything white and is sold in a cardboard box - that is responsible for causing fat in the animal or person eating it.
I do know that your body needs fat in the diet to perform certain processes at the cellular level that keep us healthy. And, I'm convinced that removing fat from your diet causes malfunctions in the brain (Alzheimer) because the synapses require fat to function properly.
The most obese people around always say that they are on low fat diets which generally means that they are consuming vast amounts of simple carbhodrates; refined sugar, potatoes, grains including rice; anything in the grocery store that is sold in a cardboard box and soft drinks.
I don’t know.
I eat a lot of meat - beef and chicken - at minimum, half a pound each day.
I also crave sugar.
Right now, in my personal confection cabinet, is a bag of Kit-Kat, five large Cadbury chocolate bars, a box of butter mints, a bag of Island (coconut-chocolate candy) and a bag of Snickers, all of which were purchased a week ago. I don’t expect any of this remaining, by the end of next week, and I’m the only one consuming it.
Am I a sugar addict?
because they are dropping dead because we want to eat them
Thank you, I needed that this morning...
“why arent more cows dropping dead of heart attacks?

LOL! Made my day. Also made me hungry for a hunk of protein. Will now forage for food.
Cholesterol is a patch material your body manufactures when red bloodcells get damaged by cracked blood vessel walls.
Reduction of dietary Cholesterol actually stresses the body more because it will salvage it from tissue in order to patch those cracks.(Mr. Fit)
Now a real scientist would wonder what causes those cracks in the first place. IOW, what keeps blood vessels flexible and smooth, or what makes them harden and crack?
If the docs in Korea working on those l8-22 year old soldiers had asked that question instead of, "what is this stuff clogging these young arteries?", we wouldn't be asking it now. You see, those l8-22 year olds grew up in the lean years of the great depression. They didn't get something they needed.
What could it be? Think about it for a while I bet you can guess.
I have read that the healthiest cooking oil is coconut oil. It is also very expensive.
Now I feel a bit better about the deep fryer I bought last week.
It is, but you want to make sure it isn’t hydrogenated. There is no need to process it like seed or vegetable oils, it is good right out of the pulp, no toxins to cook off, no racidity to perfume and color away, etc.
I eat almost no meat except venison and feral hogs. Last year I even added a roast beaver to the menu (the kind that build dams and eat trees, not the other kind that is normally for desert).
I have to add a bit of beef or pork fat to the Bambi-Burger and pork sausage to improve taste, but it is still a low fat product.
yes, “metabolic syndrome” and we can also say, “syndrome-x”, “hperinsulinism”, “triglycerides”, and that processed sugars, carbohydrates, concentrated fruit sugar and those “natural foods inculding some fruit and vegetables” that are high on the glycemic index should be avoided.
Agreed. I would say the government is culpable for this. There never was a scientific basis for a carbohydrate based diet. This is one of the continued nightmares of government “medicine” as adopted in the food pyramid during the Carter administration. This is also the time that the war on dietary fat began.
