Essential fatty acids -
They mainly provide energy. The most common omega-6 fat is linoleic acid, which the body can convert to longer omega-6 fats such as arachidonic acid AA Like EPA, AA produces eicosanoids.
However, the eicosanoids that AA produces are more pro-inflammatory 27 , Pro-inflammatory eicosanoids play a key role in the immune system. However, when the body produces too many, they can increase the risk of inflammation and inflammatory disease A healthy ratio of omega-6 to omega-3 fatty acids appears to be between 1-to-1 and 4-to-1 30 , 31 , but studies suggest that people who follow a typical Western diet may consume a ratio of between to-1 and almost to-1 When consumed, much of it is converted to another fatty acid called dihomo-gamma-linolenic acid DGLA.
Research suggests that GLA and DGLA may have some health benefits. For example, GLA may help reduce symptoms of inflammatory conditions. However, more research is needed The authors of one study concluded that taking supplements of another form of omega-6 — conjugated linoleic acid CLA — may help reduce fat mass in humans Omega-6 fats are essential fats that provide energy for the body.
However, people should eat more omega-3s than omega-6s. Oleic acid is the most common omega-9 fatty acid and the most common monounsaturated fatty acid in the diet However, consuming foods rich in omega-9 fatty acids instead of other types of fat may have health benefits.
A study found that feeding mice diets high in monounsaturated fat improved insulin sensitivity and decreased inflammation The same study found that humans who ate high monounsaturated fat diets had less inflammation and better insulin sensitivity than those who ate diets high in saturated fat.
Omega-9 fats are nonessential fats that the body can produce. Replacing some saturated fats with omega-9 fats may benefit your health. You can easily obtain omega-3, -6, and -9 fatty acids from your diet, but you need the right balance of each.
The typical Western diet contains more omega-6 fats than necessary and not enough omega-3 fats. Oily fish is the best source of omega-3s EPA and DHA. Other marine sources include algal oils. ALA mainly comes from nuts and seeds. There are no official standards for daily omega-3 intake , but various organizations offer guidelines.
Most experts recommend an intake of — milligrams per day According to the Food and Nutrition Board of the U. Institute of Medicine, the adequate intake of ALA omega-3s per day is 1.
High levels of omega-6 fats are present in refined vegetable oils and foods cooked in vegetable oils. Institute of Medicine, the adequate intake of omega-6s per day is 17 grams for males and 12 grams for females ages 19—50 years The best sources of omega-3s are oily fish, whereas omega-6s and omega-9s are present in plant oils, nuts, and seeds.
Combined omega supplements usually provide each of these fatty acids in suitable proportions, such as 2-toto-1 for omega Such oils can help increase your intake of omega-3 fats and enhance your balance of fatty acids so that the ratio of omega-6 to omega-3 is less than 4-to However, most people already get enough omega-6 from their diet, and the body produces omega For this reason, most people do not need to supplement with these fats.
Ways of doing this include eating at least two portions of oily fish per week and using olive oil for cooking and in salad dressings. In addition, try to limit omega-6 intake by limiting your consumption of other vegetable oils and fried foods that have been cooked in refined vegetable oils.

These are supplied to the body either as the free fatty acid, or more commonly as some glyceride derivative. These fatty acids are essential because they are precursors to vitamins, cofactorsand derivatives, including prostaglandinsleukotrienesthromboxaneslipoxinsand others.
