Stay away from all vegetable oils. Cook everything in either coconut oil or butter. Take a tablespoon or two of coconut oil straight up - it supports your thyroid and also saturated fat protects against PUFAs.
Opt for root vegetables over above ground veggies when possible. Exceptions are tomatoes and peppers, which are actually fruit, as well as cucumbers, zucchini, summer squash and other gourds (pumpkin, squashes, etc.) Make sure you eat them with lots of butter.
Try to get raw milk because it's got a better balance of omega 3:6. Same with grass-fed beef/lamb/bison. Same with free-range eggs. Reduce consumption of chicken, and if you do eat it, try to eat free-range chicken. (Grain-fed animals are higher in PUFA)
Make lots of bone broth (the kind our grandparents/great-grandparents would make from leftover bones). You can get beef soup bones at the supermarket or use leftover chicken/fish bones. Simmer overnight in a pot of water with a little vinegar.
Also see if you can get some gelatin (powdered collagen) - you can find it at greatlakesgelatin.com. It's a super-healing, anti-inflammatory protein. If you get the hydrolized one, you can add it to cold liquids (eg. OJ, milk, etc.) as well as hot. If you get the regular, you can even make your own marshmallows, jello, and gummy worms with it.
Stay away from farmed fish - they feed them soy and other crap. Go for the wild-caught fish, preferably warm water fish, which are lower in PUFA.
Stay away from pork as much as possible, they are mostly grain fed and high-PUFA.
