To make this information easier to digest, the review is divided over two parts; the first, the current article, explains the Basics of dietary fats. It clarifies what dietary fats are, how fats differ from a molecular perspective, which roles they play in the human body briefly , and the importance of fats in food technology. The second part is a review of the scientific literature on Dietary fats and health. It explains the most recent advances in nutrition science on the consumption of dietary fats and how this impacts health.
It also covers dietary recommendations from international authoritative bodies and the different Member States, and current consumption levels throughout Europe. Dietary fats are naturally occurring molecules that are part of our diet. They belong to a larger group of compounds named lipids that also include waxes, sterols e.
However, this distinction is not always clear, and sometimes the term fats also include other lipids, such as cholesterol. Dietary fats molecules originate from plants and animals. In plants, they are found in seeds e. Common animal fat sources are meat, oily fish e. Both plant, or, as often called, vegetable fats, and animal fats can be consumed as they naturally occur, but also indirectly, for example in pastry and sauces, where they are used to improve texture and taste.
Milk yields many popular animal fat products, such as cheese, butter, and cream. Apart from milk, animal fat is extracted primarily from rendered tissue fats obtained from livestock animals. Dietary fats, together with carbohydrates and proteins, are the main source of energy in the diet, and have a number of other important biological functions.
Besides being structural components of cells and membranes in our bodies e. Fat metabolites are involved in processes such as neural development and inflammatory reactions. When stored, body fat provides energy when the body requires, it cushions and protects vital organs, and helps to insulate the body. The lipid cholesterol, found in products like cheese, eggs, meat, and shell fish, is essential for the fluidity and permeability of the membranes of body cells.
It is also the precursor of vitamin D, some hormones, and bile salts, which enhance the absorption of fats in the intestine. The importance of dietary fats and cholesterol for human health is further explained in the second part of Facts on fats: Dietary fats and health. Understanding the basic chemistry of fats will help to understand the role that fats play in our health and in food technology.
Fatty acids have a backbone made of carbon atoms. They vary in the number of carbon atoms, and in the number of double bonds between them. For example, butyric acid C , palmitic acid C and arachidic acid C , contain 4, 16 or 20 carbon atoms in their chain, respectively. The majority of naturally occurring fatty acids, both in the diet and in the body, contain carbon atoms. Annex 1 provides a list of the most common fatty acids, their number of carbon atoms, the numbers and positions of double bonds, and in which products these fatty acids can be found.
Fatty acids are classified according to the presence and number of double bonds in their carbon chain. Both length and saturation of fatty acids affect the arrangement of the membrane in our body cells and thereby its fluidity.
Shorter chain fatty acids and ones with greater unsaturation are less stiff and less viscous, making the membranes more flexible. This influences a range of important biological functions see Facts on fats: Dietary fats and health.
Unsaturated fatty acids can also be classified as " cis " bent form or " trans " straight form , depending on whether hydrogen is bound on the same, or on the opposite side of the molecule.
Most naturally occurring unsaturated fatty acids are found in cis form. A range of TFA isomers varieties exist and are structurally different in the position of the double bond along the fatty acid molecule. Both ruminant and industrial TFA contain the same isomers, with a wider range of structures in industrial TFA, but in different proportions. PUFA can be further categorised into three main families according to the position of the first double bond starting from the methyl-end the opposite side of the glycerol molecule of the fatty acid chain:.
In addition to their formal name, fatty acids are often represented by a shortened numerical name based on the length number of carbon atoms , the number of double bonds and the omega class to which they belong see Annex 1.
Examples of nomenclature are; Linoleic acid LA , which is also referred to as C n-6, indicating that it has 18 carbon atoms, 2 double bonds and belongs to the omega-6 fatty acid family. Alpha linolenic acid ALA , or C n-3, has 18 carbon atoms, 3 double bonds and belongs to the omega-3 fatty acid family. They are important in the formation of cell membranes and are involved in many physiological processes such as blood clotting, wound healing and inflammation.
A source for AA is peanut oil. Fats can make a food more pleasant by enhancing its texture and mouth feel, its appearance, and by carrying fat-soluble flavours. Fats also have physical characteristics that are important in food manufacturing and cooking. This section addresses these food-technological aspects and will discuss some of the issues related to the reformulation of foods.
Fats are used in a wide range of applications, and have many functional properties that contribute to a final product see Table 1. The suitability of a fat for food manufacturing depends on its physical properties, such as the melting temperature and thermal stability. Fats are made up of a combination of different fatty acids, but one type generally predominates, which determines the physical characteristics.
Fats that contain a high proportion of SFA, such as butter or lard, are solid at room temperature and have a relatively high melting temperature. The higher the level of unsaturation of the fatty acids the more unstable they are; MUFA-rich oils, such as olive oil or peanut oil, are more stable and can be re-used to a greater extent than PUFA-rich oils like corn oil or soybean oil.
When deep-frying foods, it is important not to overheat the oil and to change it frequently. Exposure to air and moisture will affect the quality of the oil by the formation of free fatty acids or their degradation.
Sunlight can break down the vitamin E and n-3 fatty acids in vegetable oils. Vegetable oils are obtained by washing and crushing the seeds, fruits or nuts, and using heat to separate the oil. The oil is then refined to remove any unwanted taste, smell or colour. The latter is a small fraction of the total quantity of produced vegetable oils. The fatty acid composition varies widely among different vegetable oils, and technical processes, like hydrogenation and interesterification, are used to obtain preferred characteristics.
These processes have been debated from a human health perspective and are discussed below. Other technical solutions to modify the properties of oil include blending and fractionation. Hydrogenation is a process that converts liquid vegetable oils, depending on the level of hydrogenation from partial to full hydrogenation into semi-solid or solid fats to make them suitable for food manufacturing purposes.
Hydrogenated vegetable oils are usually cheaper than animal fat with the same physical properties, they are more heat-stable, and have increased shelf life. Partial hydrogenation reduces most but not all, of the double bonds and modifies the properties of the oil without increasing the SFA content to a great extent.
The level of saturation of the fatty acids can be controlled, so that a range of consistencies, with increasing viscosity and melting temperature, can be realised. Full hydrogenation, on the other hand, does not result in TFA, as all of the fatty acid molecules have been saturated.
Thus, oil that has not undergone the full hydrogenation process contains TFA, which has been linked to adverse health effects see Facts on fats - Dietary fats and health. For this reason the food industry is reformulating their products by reducing the use of partially hydrogenated fats. Fats can be interesterified, as an alternative to the hydrogenation process, without the formation of TFA. In this chemical process, the fatty acid chains are rearranged within or between the triglyceride molecules, creating new triglycerides.
SFA in most vegetable fats are located in the outer positions of the triglyceride molecule the sn-1 and sn-3 positions. Interesterification leads to the generation of fats with a higher proportion of SFA in the sn-2 middle position, similar to that of animal fats such as lard.
The process is carried out by blending different oils e. With the help of chemical catalysts or enzymes, the fatty acids are redistributed, without modifying the actual fatty acid molecules. These oils, produced from seeds with novel fatty acid composition, have a high content of unsaturated fatty acids.
They can replace the trans fats while maintaining food product quality. However, limited market supplies of these substitute oils may be a bottleneck. To this end, the most widely used replacers are fully hydrogenated vegetable oils with interesterified stearic acid explained above and palm oil, both high in SFA. These properties allow for a range of applications, and it has been widely used to replace partially hydrogenated vegetable oils.
From a nutritional point of view, as with all saturated fats, moderating its intake is advisable. Palm oil has become a topic of debate due to the environmental and social concerns related to its production. The Roundtable on Sustainable Palm Oil RSPO therefore issues a certification, a seal of approval, if the palm oil was produced without undue harm to the environment or society, and if the product is traceable through the supply chain.
Beyond energy, they are indispensable for a number of important biological functions including growth and development. This first part of the EUFIC review Facts on Fats - the Basics , explains what dietary fats actually are, where they can be found, what is their molecular structure, and what technological properties they have to improve taste, texture, and appearance of foods. The second part of the review, Dietary fats and health , addresses the consumption of dietary fats and how it relates to human health.
For more information please see our Dietary fats infographic which is available to download, print and share. The n- omega designation gives the position of the first double bond counting from the methyl end of the fatty acid molecule. Saturated fat may not be associated with a greater health risk whilst trans fat could have a role. Algal oil as a possible source of omega-3 fatty acid DHA to improve blood lipids in people without heart disease.
View All. What are dietary fats? Zooming in on the molecular structure, how are dietary fats built? Fatty acids Fatty acids have a backbone made of carbon atoms. Classification of unsaturated fatty acids cis and trans Unsaturated fatty acids can also be classified as " cis " bent form or " trans " straight form , depending on whether hydrogen is bound on the same, or on the opposite side of the molecule.
Classification of PUFA omega fatty acids PUFA can be further categorised into three main families according to the position of the first double bond starting from the methyl-end the opposite side of the glycerol molecule of the fatty acid chain: Omega-3 or n-3 fatty acids have the first double bond at the third carbon atom and include mainly alpha linolenic acid ALA and its derivatives eicosapentaenoic acid EPA and docosahexaenoic acid DHA.
Omega-6 or n-6 fatty acids have the first double bond at the sixth carbon atom and include mainly linoleic acid LA and its derivative arachidonic acid AA. Omega-9 or n-9 fatty acids have the first double bond at the ninth carbon atom and include mainly oleic acid.
Fatty acid terminology In addition to their formal name, fatty acids are often represented by a shortened numerical name based on the length number of carbon atoms , the number of double bonds and the omega class to which they belong see Annex 1.

Butter is a dairy product with high butterfat content which is solid when chilled and at room temperature in some regions, and liquid when warmed. It is made by churning fresh or fermented cream or milk to separate the butterfat from the buttermilk. It is generally used as a spread on plain or toasted bread products and a condiment on cooked vegetables, as well as in cooking, such as baking , sauce making, and pan frying. Butter consists of butterfat , milk proteins and water, and often added salt. Most frequently made from cow's milk, butter can also be manufactured from the milk of other mammals , including sheep , goats , buffalo , and yaks. Salt such as dairy salt , flavorings such as garlic and preservatives are sometimes added to butter.
A wide variety of products based on edible fats and oils is available to consumers. Shortenings, salad and cooking oils, butter, margarines and tablespreads, mayonnaise, spoonable and pourable salad dressings, and confections are some of the widely available products that are based entirely on fats and oils or contain fat or oil as a principal ingredient. Many of these products also are sold in commercial quantities to food processors, snack food manufacturers, bakeries, restaurants, and institutions. They account for more than half of dietary fat, the majority of which is derived from vegetable sources soybean, canola, cottonseed, corn, palm, etc. In recent years, a number of trait-enhanced vegetable oils have been commercialized. Their fatty acid compositions have been modified via either traditional selective hybridization or gene insertion techniques. These oils generally tend to be lower in polyunsaturates e. Trait enhanced oils are designed to deliver two primary objectives: 1 improved nutritional profile and 2 improved oxidative and flavor stability thereby precluding the need for partial hydrogenation.

BUTTER AND DAIRY SPREADS
Butter is made from the butterfat of milk, whereas modern margarine is made mainly of refined vegetable oil and water. In some places in the United States, it is colloquially referred to as oleo , short for oleomargarine. Due to its versatility, margarine can be used as an ingredient in other food products, such as pastries, doughnuts, cakes and cookies. In , the German structural chemist Wilhelm Heinrich Heintz analyzed margaric acid as simply a combination of stearic acid and the previously unknown palmitic acid. Emperor Napoleon III of France offered a prize to anyone who could make a satisfactory butter alternative, suitable for use by the armed forces and the lower classes. In , he sold the patent to the Dutch company Jurgens , now part of Unilever. John Steele wrote in his California gold miner's journal: "I became acquainted with Mr. Daniels, from Baltimore, who

On July 11, , trans fat labeling became law with a major key provision stipulating that trans fat was to be listed as a separate line on nutrition labels, but foods containing less than 0. On January 1, the new law stipulated that saturated and trans fats were to be included as one line on nutrition labels. In the number of zero trans foods was essentially non-existent. A recent report indicates that over the period the trans fat content of baked goods had decreased from 0.
