Nuts are fairly high in Linoleic Acid, an Omega-6 inflammatory precursor, with a few exceptions like macadamia nuts which are lower. A diet high in nuts, would presumably skew the Omega-3 : Omega-6 ratio toward pro-inflammatory processes.
But nuts should not make up the bulk of our diet. On the spectrum of inflammation and Omega-6, a small handful of raw or lightly roasted nuts is nothing compare to stir-frying or baking with corn, grapeseed, margarine or soybean oil.
Nuts are much more than Linoleic Acid. In fact, they are pretty complete nutritional source. They have a good balance of fat/carbohydrate + fiber/protein, have a low impact on blood sugar, are a great source of antioxidants like Vitamin E and important minerals like selenium and magnesium. Actually, one of my favorite snack or dessert is a dozen of macadamia nuts, a square of dark chocolate and a green tea with a squeeze of lemon or coffee with a dash of cinnamon.

There are definitely better choices in every food categories, but over-analyzing our food intake is a good way to stress ourselves and make every little dietary decision an internal struggle. We have to stay informed and vigilant, but we have to pick our battles. Using healthier options like good quality olive or coconut oil preparing our food or passing on the box of donuts at the office is worth the effort; stressing over the Omega-6 content of 10 almonds is not.
