The Skinny on Fat: Bad Fats How fats fit into your healthy diet. Would all of our weight loss problems be solved if we just eliminated fat from our diets? Fats are an important part of a healthy diet:
The authors concluded we have been concentrating on reducing one type of fat in our diet when instead we should be promoting a Mediterranean dietexercise and reducing stress to reduce our chances of heart disease.
Or, as the editorial suggests, have we really got it all wrong? Science and medicine have never suggested saturated fat itself, for instance from a diet rich in fatty meat or processed foods, blocks your arteries vessels that carries blood from the heart to other organs.
LDL and related particles enter the artery wall where they are chemically modified, triggering a vicious cycle of inflammation and cholesterol accumulation. It is this cycle of inflammation and cholesterol accumulation that leads to heart disease and stroke.
So doctors look beyond simple measures of LDL cholesterol to measure your risk. This gives you an idea of the level of damaging particles or non-HDL cholesterol.
If we understand that raised blood cholesterol levels in particular, raised LDL increase your risk of heart disease and stroke, then it stands to reason that reducing their levels might decrease your chances.

This is exactly what two recent studies showed. These provided the highest form of evidence in over 40, patients; they looked at how two cholesterol-lowering drugs significantly reduced cardiovascular events, like heart attacks and stroke.
Neither drug has anti-inflammatory effects. Instead, their success is attributed to reduced levels of harmful cholesterol-carrying particles, including LDL cholesterol. In one study, participants swapped butter for polyunsaturated margarine as a way of reducing their saturated fat intake.
Two landmark studies in people who ate Mediterranean-style diets show what happens when you eat less saturated fat.
Replacing saturated fat in the diet with foods containing healthier unsaturated fat, like the fats in nuts, extra virgin olive oil, polyunsaturated margarine — but not processed carbohydrates — reduced levels of heart attacks and premature death.
Downplaying the role of dietary saturated fat in heart disease prevents health care workers from managing cardiovascular risk using diet. Any recommendation to not be so focused on saturated fat will therefore increase population levels of blood cholesterol, increasing the need for statins and other cholesterol-lowering drugs.
The implication, that one of the most thoroughly researched areas of medical science — that excess saturated fat puts you at risk of heart disease and stroke — is a hoax, misrepresents the evidence. But currently available evidence does not support these common beliefs. In a surprise finding, one study in women who had been through the menopause found a diet richer in saturated fat was linked with less, not moreprogression of coronary atherosclerosis.
Second, whether eating saturated fat increases your chances of dying from heart disease. When researchers combined the results from 41 research papers published from toeating saturated fat was not linked with dying from heart related diseases, like heart attack, stroke or type 2 diabetes.
Many of us think saturated fat is bad for us because it increases levels of low-density lipoprotein cholesterol or LDL in our blood. But is LDL-cholesterol really that bad? When researchers studied all the research papers written in English that investigated the effects of LDL-cholesterol on the deaths in people over 60, they had some surprising results.
While LDL is largely responsible for delivering cholesterol to cells around the body, HDL cholesterol transports extra cholesterol back to the liver for recycling. Eating three eggs a day increased levels of HDL cholesterol in the short term.
So, eating normal amounts of saturated fat will not tip the balance. We need saturated fat in our diet to form the building blocks for the cells in our body and to help our cells communicate with each other.
The long-term effect of eating too much cholesterol on the ratio of total against HDL cholesterol is not clear.
Prediabetes and type 2 diabetes are caused by a drop in insulin sensitivity blamed on “intramyocellular lipid,” the buildup of fat inside our muscle cells.

A short-term study suggests eating moderately high levels of cholesterol may not be bad. Researchers found that eating three eggs a day containing mg cholesterol for 12 weeks did not increase LDL-cholesterol.
Rather, we should enjoy our meals containing moderate amounts of saturated fat and be physically active. That will be more effective in keeping us healthy.
The author mentions the study of progression of artery disease in women who have gone through the menopause. This shows women with the highest saturated fat intake had the lowest LDL cholesterol levels despite taking less lipid-lowering treatment.
This might be explained, as some researchers suggestby genetic factors that allow some people to tolerate saturated fat better, leading to a lower LDL and a reduced risk of heart disease.
And rather than eating moderate amounts of saturated fat, as the author suggests, there is ample evidence for avoiding saturated and trans fats, replacing them with healthier ones and reserving saturated fats as treats.
We also differ in our opinions of the best marker of heart-disease risk that your doctor might consider when analysing blood test results. Use of the total cholesterol to HDL ratio, as the author proposes, has declined because levels of HDL cholesterol itself may not be a marker of heart disease protection.
And raising HDL has not reduced the risk of heart disease.Like monounsaturated fats, these good fats help fight bad cholesterol. Polyunsaturated fats stay liquid even in the cold because their melting point is lower than that of monounsaturated fats.
You can find polyunsaturated fats in foods like salmon, fish oil, sunflower oil, and seeds. Saturated fats and unsaturated fats are found in a variety of foods.
The types of fats to consume if you are following a lipid-lowering diet has been the subject of some controversy. Some studies suggest that these fats are not created equal.

The fattier the fish, the better. Oily fish such as salmon, tuna, sardines, mackerel, and trout are full of omega-3 fatty acids. According to the American Heart Association, people should eat at least two servings of fatty fish per week to help balance out their fatty acid ratio of omega-6 to omega-3 fats.
