Because everything in The Origin Diet is based on a thorough review of the research, it remains correct and stands the test of time (only info based on a few studies changes from year to year). The only change I would make in the supplement section is to further emphasize the need for the omega-3 fats, especially EPA and DHA. If you can’t get 2+ servings of fatty fish into your weekly diet routine, then make sure to take a supplement that contains at least 200 milligrams of DHA or at least 1 gram of a combination of EPA and DHA. If you choose to take more than that, be sure to tell your physician, since the omega-3s can be blood thinners at high doses.
