A healthy ideal omega-6 to omega-3 ratio for your body is 1:1.  It can range from 1:1 to 5:1 and still be healthy. 

The ratio in peanuts is 12,000:1   ,   cashews 125:1  ,   almonds 5,000:1.

Walnuts 9,000:36,000. A 4:1 ratio in favor of Omega 3.

If you eat peanuts or other foods that are high in omega-6, larger amounts of omega-3's need to be added to the diet to even out the ratio. Some excellent sources include flax seed, walnuts, hemp seeds and beans. 

So what are the consequences to human health of an n-6:n-3 ratio that is up to 25 times higher or more than it should be?

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

Vegetable oils like corn, soybean, safflower, sunflower, and cottonseed oil have very high levels of omega-6 and do not contain any omega-3.
