Fat is back. Everything from rice bran to coconut oil line grocery store shelves, all spouting various health claims. Should you switch? We help you decide.

Coconut Oil
Refined or hydrogenated coconut oil is often used in processed foods like baked goods, nondairy creamers and movie theater popcorn because of its neutral flavor and relatively long shelf life. Since it’s a whopping 91 percent saturated fat, its best use may be outside the kitchen—as a skin moisturizer!

Peanut Oil
Slightly higher in saturated fat than canola and olive oils, refined peanut oil adds a mild nutty flavor to fried foods and is safe for people with peanut allergies. It’s a good choice for frying because it can stand up to high heat. More intensely flavored roasted peanut oil is best used to add flavor to Southeast Asian dishes or drizzled over grilled seafood and vegetables.

Sesame Oil
Traditionally used in Asian and Indian cuisines, sesame oils are low in saturated fat. Nutty in flavor, light sesame oil is used primarily for stir-frying. Dark sesame oil has a rich, bold taste so it’s used in smaller quantities to add classic Chinese take-out flavor to your dishes.

Rice Bran Oil
This neutral-flavored oil has a fairly even ratio of poly- and monounsaturated and saturated fats, and has been used in some restaurants in place of trans fat-loaded partially hydrogenated oils to fry foods. Rice bran oil contains a higher level of the antioxidant tocotrienol, a form of vitamin E claimed (but not proven) to prevent some cancers and lower cholesterol.

Vegetable Oil
Usually a blend of corn, soybean and/or sunflower oils, this neutral-flavored oil is a rich source of polyunsaturated fats. A good multitasker in the kitchen, vegetable oil is a decent backup choice to omega-3-rich canola oil.

Canola Oil
Also a great source of monounsaturated fats and among the lowest in saturated fat, canola oil is your best choice for a multipurpose oil for frying, sautéing, baking and marinades. Both canola and light olive oils have indistinct flavors, but canola is higher in omega-3 fats, which protect against heart disease and autoimmune diseases.

Olive Oil
Rich in cholesterol-lowering monounsaturated fats, extra virgin olive oil is fruity and tangy—save it for drizzling over soups, pastas, salads and toasted bread. “Light” olive oil is lighter in flavor and color (not in calories or fat); “pure” is typically a blend of refined olive oil and virgin. Use these milder versions for grilling, roasting and sautéing.
