Best sources: Oily fish like herring, salmon, sardines, lake trout and albacore tuna. You can also get smaller amounts from flaxseed, chia seeds, walnuts and canola oil.

Watch out for this sneaky clogger. There's a reason you should avoid trans fats: They raise total and LDL cholesterol while lowering good HDL. Thanks to updated labeling laws, they're easier to spot on many products, but the bad news is, they still lurk (unlabeled) in margarine, shortening, frozen baked goods, doughnuts and fast-food french fries. Many people still consume nearly a gram and a half per day. Since no amount is safe, steer clear of these foods completely.
