Worst foods for high Omega-6 and low Omega-3. This does not mean that these foods are not healthy, but rather it means you need to eat a lot more high Omega-3 foods to help balance it out.
For my own diet, I eat almost none of the high O-6 foods, although carrots, sweet potatoes and some of the fruits are often included on my diet, especially fruits in the summer time. I succumb to grits (shrimp and grits) occasionally, and I love hummus (which is made with chick peas) although I eat a lot less of it anymore.
Beets, and Beet greens
Brown rice, brown rice flour
Hard red winter wheat
Chickpeas (garbanzo beans)
Dry roasted peanuts
factory grain-fed meats
Bread (whole grain is 3X higher in O-6 than white bread, go figure!)
Portabella mushrooms, raw
Spaghetti (WW is worse than white)
