Potato chips are one of my guilty pleasures. When I started the low omega 6 diet, I realized that most of the chips have a ton of omega 6 fats.
The omega 6 content is much lower than other chips because these chips are baked with less oil.
To figure out the omega 6 content, I look at the Polyunsaturated Fats, which consists of omega 3 and omega 6.
Then I look at the oils used for these chips. Sunflower, safflower and canola have negligible amounts of omega 3 compared to omega 6 (Nutrition Facts for Low Omega 6 Diet). So I assume all of the Polyunsaturated Fats are Omega 6 oils.
For comparison -
18 slices Lay’s Potato chips (1oz) = 8.5g Omega 6
20 slices Kettle brand Real Sliced Potatoes (1oz) = 0.5g Omega 6
