Although omega-6s are important for lowering LDL cholesterol , high amounts or high ratios of omega-6s to omega-3s can increase inflammation.

However, when too many of them are produced, they can increase inflammation and inflammatory disease Although omega-6 fats are essential, the modern Western diet contains far more omega-6 fatty acids than necessary The recommended ratio of omega-6 to omega-3 fatty acids in the diet is or less.

When consumed, much of it is converted to another fatty acid called dihomo-gamma-linolenic acid DGLA. One study showed that taking a high dose of GLA supplements significantly reduced a number of symptoms of rheumatoid arthritis Another interesting study found that taking GLA supplements in addition to a breast cancer drug was more effective at treating breast cancer than the drug alone Conjugated linoleic acid CLA is another form of omega-6 fat that has some health benefits.
For example, one large study found that taking 3.
Omega-9 fatty acids are monounsaturated, meaning they only have one double bond. It is located nine carbons from the omega end of the fatty acid molecule. Oleic acid is the most common omega-9 fatty acid and the most common monounsaturated fatty acid in the diet. In fact, omega-9 fats are the most abundant fats in most cells in the body.
However, consuming foods rich in omega-9 fatty acids instead of other types of fat may have a number of beneficial health effects. Another 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 You can easily obtain omega-3, -6 and -9 fatty acids from your diet.
