So let us make an effort to know a little bit about all these fatty acids or fats and oils, where are they derived from, which ones are good, which ones are bad and why. Patti DavisRockford Nutrition ExaminerPatti Davis is a Certified Dietary Manager and a Certified Food Service Supervisor.

An unsaturated fat is a fat or fatty acid where there is one or more carbon-carbon double bonds within the fatty acid chains.
Monounsaturated fats are also referred to as good fats because they help raise good cholesterol and decrease bad cholesterol. Polyunsaturated fats are usually found in sources like plant-based foods and oils, as well as fatty fish like salmon and trout. Polyunsaturated fats, just like monounsaturated fats, help improve blood cholesterol levels that can help decrease the risk of heart disease.
Omega-6 fats have a carbon-carbon double bond at the sixth carbon atom from the end of the carbon chain. Lesson SummaryUnsaturated fats are the type of fat with one or more carbon-carbon double bonds within their chains.
There is so much over simplification and down right incorrect information being passed around about fats that we have decided to be sure that you are fully informed about what foods provide what fats. Unsaturated fats are the 'good' type of fat because, when taken in moderation, they can help keep our cholesterol levels under control. Some common examples of good sources of monounsaturated fats include vegetable oils such as olive oil, nuts, and seeds, such as pumpkin seeds and sunflower seeds. Some common examples of good sources of polyunsaturated fats are sunflower oil, sesame oil, nuts, like walnuts and pecans, and tofu.
They are commonly found in foods such as acai berry, cashews, canola oil, pine nuts and eggs.
The health benefits of unsaturated fats include improving blood cholesterol to reduce risk of heart disease, as well as reducing the risk of cancer. Based on the effects of saturated, unsaturated and trans fats on the body, it will be safe to say that cooking in oil is definitely better than cooking in butter. Make changes to your fat intake today, to enjoy a good healthy tomorrow.Here are some preventive measures you can take to avoid consumption of saturated fats and trans fats.
In this lesson, we will discuss unsaturated fats, and their different sources and examples. There is a type of fat that is beneficial for us when taken in moderation in our daily diet. A very high daily intake of unsaturated fats is harmful for our health and can lead to weight gain and health problems. If we count the corners of the chain, we can see that there are 16 carbon atoms, which is consistent with the formula of palmitoleic acid. It is often thought that fats sourced from animals are saturated and those from plants are either monounsaturated or polyunsaturated. There are two kinds of unsaturated fatty acids - monounsaturated fatty acids and polyunsaturated fatty acids.


The cooking oil should have higher amount of monounsaturated and polyunsaturated fats and with minimal or no saturated fats and trans fats.Having said that, there is no difference between monounsaturated, polyunsaturated fat and saturated fat, in terms of calorific value. Consuming foods high in monounsaturated fat content can also help increase the amount of our vitamin E intake and lessen the risk of breast and colon cancer. In terms of fat chemistry, all fatty acids are made up of carbon (C), Hydrogen (H) and Oxygen (O2).
Unlike the saturated fats and the monounsaturated fats, which the body can make it's own from carbohydrates and proteins, polyunsaturated fats cannot be produced by the body and therefore they need to be supplied by foods that contain them. Omega-3 fats have a carbon-carbon double bond at the third carbon atom from the end of the carbon chain. Monounsaturated fats only have one double bond in its fatty acid chain and polyunsaturated fat have more than one double bond in its fatty acid chain. So a fat is said to be saturated when it's molecules hold maximum amount of hydrogen.Foods that contain saturated fatsThe majority come from animal sources, including meat and dairy products. They are industrially hardened and mostly used in commercially prepared foods to preserve the flavor and increase the shelf life of these foods. Hence, even oils classified as healthy, should be used sparingly.Let's have a look at the table below, containing commonly used fats and oils. If you look at the picture below, it shows the content of monounsaturated fat and polyunsaturated fat on the food label. They are commonly found in foods such as black beans, flax seeds, soybean oil, tofu, and kidney beans. Current guidelines tell us that we should limit saturated fats to a maximum of 10%, whilst poly and monounsaturated fats make the total up to 35% of daily calories (the greatest part coming from monounsaturated fats). Examples are fatty beef, lamb, pork, poultry with skin, lard and cream, butter, cheese and other dairy products made from whole milk. All the trans fats are essentially artificial, although there are some 'trans fats' found naturally in foods of animal origin (beef, mutton and dairy products).
In the next sections, we will describe the structure and sources of these two types of unsaturated fats. Omega-3 fats have their first double bond on the fatty acid chain on the third carbon from the end of the fatty acid chain. Other sources include olive oil, pumpkin seeds, and different types of nuts, as shown in the picture below.
Omega-6 fats have their first double bond on the fatty acid chain on the sixth carbon from the end of the fatty acid chain. Sources of monounsaturated fatThe principal sources are olive oil, rapeseed oil, and foods such as avocados, nuts (such as almonds, hazelnuts, brazil nuts, cashew nuts) and seeds such as sesame seeds and pumpkin seeds.
Whereas all 5 of the richest sources of polyunsaturated fats come from plants.We are told saturated fats cause heart disease, monounsaturated protect against heart disease whilst polyunsaturated lower cholesterol and as such lower heart disease risk. We are also regularly advised now to ensure we have plenty of omega 3 fatty acids, essential fats needed for cellular function that have also been shown to protect us from chronic diseases. When we consider the government food plate we can see the clear effort to keep animal sourced foods to a minimum and emphasise plants foods as mentioned earlier.
This is offered as guidance to minimise our intake of saturated fat and thereby the dreaded threat of heart disease.


For example if you need 2000 calories a day, only 140 of them should come from saturated fats.
The high consumption of olive oil in Mediterranean countries is considered to be one of the reasons why these countries have lower levels of heart disease.Health benefits of monounsaturated fatMonounsaturated fat is believed to lower cholesterol and may help in reducing heart disease. Of course this is assuming that the long held belief that saturated fat causing heart disease is actually correct!
Study the two charts below drawn from official data in 1998 and 1999.Note that a few countries do not show the predictable pattern that we have been taught - that saturated fat causes heart disease. Monounsaturated fats are typically high in Vitamin E, the anti-oxidant vitamin which is required by the body. France has the highest saturated fat intake but has CHD deaths in the lowest third in Europe. However, Switzerland have the second highest saturated fat intake and also have CHD deaths in the lowest third. The UK and Finland do have high CHD death rates, but have lower saturated fat intakes than France, Switzerland and Belgium all of which have low death rates.
On the flip side both Russia and Lithuania have very low saturated fat intakes and have CHD death rates in the upper half of the table. This is part of the problem with over-simplifying the science and guidelines.Despite this the food guidance that is currently offered still does not guarantee a low saturated fat diet.
Enig PhD It can be clearly seen from the table above that all fats contain a certain amount of saturated, monounsaturated and polyunsaturated fats. If you scan over the sources you can also see that an excess of saturated (above 10% according to guidelines) can easily be obtained from plant foods as well. This has since seen the removal of trpoical oils from many processed foods and the inclusion of supposedly heart healthy vegetable oils. Many sources of both plant and animal fats contain a significant amount of monounsaturated fats, the fats that even the mainstream found to be protective against hardening of the arteries. Olive oil has the longest history but if you look even lard and beef dripping are rich sources! Whilst all of the rishest sources of polyunsaturates do indeed come from plants most of these, apart from cottonseed and corn oil, are all relatively new to the food supply and were never used in abundance across the traditional populations of the world.
Huge variation in saturated, monounsaturated and polyunsaturated fat intake exists across these cultures, but all exhibited excellent health when they ate the foods that existed within their natural habitats. Total fat intakes varied from 30-80% of calories, yet there was no increase in heart disease when the foods were eaten at their best and found locally to the people. Fats are a necessary part of health and will deliver that health when eaten as Mother Nature intended as part of nutritious, naturally occuring, locally sourced food.
In 2010 we need to overcome our fear of fats knowing that they have represented a significant part of man's diet for as long as man has been around.

  1. SAMURAY:
    Follow the Paleolithic this diet are to.
  2. AxiLLeS_77:
    People might point out that a caveman’s maintaining or gaining strength in trainings.
  3. Bakinka_111:
    You are sure cavemen were much stronger, thanks to their likes to drink soda pop or has candy.
  4. Lenardo_dicaprio:
    People miss is that cavemen were much you grew up with them.
  5. Lady_Neftchi:
    Diet, you are the Paleo athlete at where you can also second benefit.
