too much omega-6, not enough omega-3 - making us sick

How too much omega-6 and not enough omega-3 is making us sick

Death by vegetable oil

So what are the consequences to human health of an n-6:n-3 ratio that is up to 25 times higher than it should be?
The short answer is that elevated n-6 intakes are associated with an increase in all inflammatory diseases – which is to say virtually all diseases. The list includes (but isn’t limited to):

• cardiovascular disease
• type 2 diabetes
• obesity
• metabolic syndrome
• irritable bowel syndrome & inflammatory bowel disease
• macular degeneration
• rheumatoid arthritis
• asthma
• cancer
• psychiatric disorders
• autoimmune diseases

The relationship between intake n-6 fats and cardiovascular mortality is particularly striking. The following chart, from an article entitled Eicosanoids and Ischemic Heart Disease by Stephan Guyenet, clearly illustrates the correlation between a rising intake of n-6 and increased mortality from heart disease:

As you can see, the USA is right up there at the top with the highest intake of n-6 fat and the greatest risk of death from heart disease.
