Note: It is technically more accurate to call saturated and unsaturated fats types of fatty acids, as it is specifically the fatty acid found in a fat that is either saturated or unsaturated. Unsaturated fats increase High-Density Lipoprotein (HDL or good cholesterol) and decrease Low Density Lipoproteins (LDL or bad cholesterol). There are many different kinds of saturated and unsaturated fatty acids, and science is still trying to understand how they all function in the body. Food industries around the world have been phasing out trans fats since the mid-2000s, often due to public demand or government regulation, but even food products that claim to have "0g of trans fat" may usually contain up to 0.5g legally.
In general, monounsaturated and polyunsaturated fats are believed to promote good cholesterol (HDL) by helping move bad cholesterol to the liver, where it can be metabolized. Understanding how carbohydrates, saturated fats, and unsaturated fats operate in the body is a topic of ongoing scientific research.
A small collection of notable studies from recent years regarding the relationship between saturated fats and cardiovascular disease. While most studies have focused on the alleged connection between saturated fats and cardiovascular disease, others have looked at possible links between these fats and cancer. It is important to know, though, that many foods have a combination of saturated and unsaturated fats. Doctors and dietitians usually follow what is presently mainstream science by telling their patients to limit the amount of saturated fats they eat in a day.
Because many studies have found low-carb, low-saturated fat diets to be beneficial, some experts now recommend vegetarianism or at least less meat consumption. These different chemical structures result in different physical properties for saturated and unsaturated triglycerides.
Less than 10% of your total recommended calorific intake should be sourced from saturated fats.
Too much consumption of either unsaturated or saturated products can cause you harm so Anthony is not ENTIRELY incorrect as too much of unsaturated fat can cause you as much harm as saturated fat can at a high intake rate.
I'm sure most of us have heard that saturated fats are solid at room temperature, and unsaturated fats are liquid at room temperature. A typical fat or oil will of course be a mixture of different triacylglycerols, but the underlying principle is the same.

Most dietary recommendations suggest that, of the daily intake of fat, a higher proportion should be from unsaturated fats, as they are thought to promote good cholesterol and help prevent cardiovascular disease, whereas an overabundance of saturated fats is thought to promote bad cholesterol. Sources of HDL include onions and Omega-3 fatty acids like flax oil, fish, foods rich in fiber like grains. Polyunsaturated fats are where omega fatty acids, such as omega-3s and omega-6s, are found. Trans fats are actually a kind of unsaturated fat, but they stand out from other types of fat because they very rarely occur in foods naturally.
Hydrogenation extends the shelf-life of foods, but it also solidifies fats that would otherwise be liquids.
Too many saturated fats, too often, may increase bad cholesterol (LDL), clog arteries, and increase the risk of cardiovascular disease and events, such as heart attacks and strokes. While numerous studies since the 1960s have found links between saturated fats, diseases, and cancers, several other large studies in recent years have found no significant correlation. Various studies have found links between saturated fatty acids and breast cancer[3], colorectal cancer[4], ovarian cancer[5], pancreatic cancer[6], and prostate cancer[7]; and at least one study found saturated fats contributed to the failure of prostate cancer treatments. Most experts recommend that no more than 25-35% of one's daily calories come from any fat, and that only 7-10% specifically come from saturated fats. Saturated fats, like butter or bacon grease, solidify at room temperature, while unsaturated fatty acids, like olive oil, tend to be liquid at room temperature. However, if in the pursuit of this goal, you replace saturated fat with carbs or partially hydrogenated oils, the effect on your health may be just as bad, if not worse. Saturated fats cause a build up of LDL cholesterol in the blood stream, which blocks the arteries and leads to an INCREASED chance of developing atherosclerosis and other coronary heart diseases.
I'm wondering how this relates to their chemical structure -- saturated fats contain only single bonds between carbons, yet to qualify as an unsaturated fat a C=C double bond must exist.
However, a few studies have found that little evidence for a strong link between the consumption of saturated fat and cardiovascular disease. Manufacturers created this process partly because saturated fats, which had been used previously, had grown very unpopular; however, there was still a need to create foods that would last. It is possible that saturated and unsaturated fatty acids are much more complex and nuanced than previously thought.

This roughly equals 60 to 65 grams of fat (and specifically 16 to 20 grams of saturated fat) in a daily diet of 2,000 calories. Saturated fatty acids contain carbon atoms that connect with each other in a chain of single bonds. Unsaturated fatty acid molecules are not tightly packed, which makes it easier for them to pass more fluidly through the body. The body often needs the things it cannot make itself (such as essential fatty acids), but often needs little of the things it contains in high amounts (it produces it with other compounds, and therefore doesn't need as much). Unsaturated fats increase the amount of HDL cholesterol, which DECREASES the amount of LDL cholesterol in the bloodstream, therefore DECREASING the likelihood of blocked arteries and thus coronary heart diseases. The amount of energy needed to disrupt these interactions (which determines the melting point of the fat or oil) is determined by the energy associated with all of these bonds added together. Unfortunately, these solid trans fats have the same effects that saturated fats have: they clog the arteries.
They are being replaced with interesterified saturated fats and sometimes with traditional saturated fats, such as lard or palm oil. Further research is required to know if there is an actual link between saturated fat and these illnesses.
Just because saturated fats are within our body doesn't mean high consumption of them is good for you. In a saturated fat the acyl chains are able to align perfectly right along their length, maximising intermolecular interactions.
Unsaturated fatty acids contain some carbon atoms that bond with each other using double bonds.
So these carbon atoms can only bond with one hydrogen atom instead of two, and are said to be "unsaturated".A fatty acid with a single double bond is a monounsaturated fatty acid, while a fatty acid with two or more double bonds is known as a polyunsaturated fat. And those thousands of studies by main stream and alternative researcher showing the negatives of saturated fats are usually pretty good.
