Omega-3 are essential to good health. They help your body burn fat more efficiently! They raise your metabolism & lower your triglyceride levels. Sources include ground flaxseed, flaxseed oil, fish oil, tuna, salmon, sardines, walnuts & leafy greens. I keep a jar of flax seeds in my pantry & add them in my recipes, mix them with my Greek yogurt, protein drinks, toss on a salad, and in my steel cut oats. Flaxseed is are an excellent source of fiber.
