So, saw this advertised the other day. It’s Kellogg’s Raisin Bran® Omega-3 from Flaxseed cereal. Both the ingredients list and the picture make it clear you’re getting whole flaxseed:
Well, at the risk of being indelicate, the only thing getting 250mg of ALA (an omega 3 fatty acid) from flaxseed is your poop. Whole flaxseeds are not digestible! Boy, they should put this picture in the dictionary next to “healthwashing.”
So if a product includes whole flaxseeds, you might as well consider that an insoluble fiber.
BTW, you don’t really want to buy ground flaxseed either, since the fatty acids can oxidize quickly (not a good thing!). If you want to add flaxseed to your diet, my suggestion is to buy whole flaxseeds and grind them yourself with a nice ceramic spice grinder.
But unless you are vegetarian or vegan, you’re better off with animal sources of omega 3 like salmon.
