Antioxidants: Too much of a good thing?

Evidence continues to accumulate, little bit by little bit, that fat-soluble antioxidants and antioxidant vitamins–in this case, lycopenes, lutein, and beta-carotene vs. vitamin E–interfere with each other’s absorption. Here’s the short description and here’s the original paper so you can see how the little bits accumulate. For me, the take-home lesson is easy: eat food, not supplements.

  • Does this mean that all the fresh ‘super’ juices like Odwalla’s may not deliver as well on the promise as they might indicate?

    Such as the:
    ” Mo’ Beta®” which is promoted on their website as:
    • Antioxidant Vitamins C, E, and Beta-carotene •Fruit Juice Drink
    Here’s a smooth, fruity blend of orange juice and peach, mango, and plum purees, plus pineapple juice, graced with a touch of honey and antioxidants vitamins C, E, and Beta-carotene. This bright blend offers real nutrition from nature’s best, with a special array of green tea extract, and loads of antioxidants in every bottle. You may not live forever but you’ll feel “mo’ beta”!
    * Orange Juice
    * Peach Puree
    * Mango Puree
    * Plum Puree
    * Pure Filtered Water
    * Pineapple Juice
    * Evaporated Cane Juice
    * Vitamin C (Ascorbic Acid)
    * Vitamin E (d-alpha Tocopherol Acetate)
    * Lemon Bioflavonoids
    * Beta Carotene
    * Zinc Gluconate
    * Green Tea Extract ”

    This is a pretty expensive way to get your servings of fruit–in a sugar sweetened juice. I’d rather go with the WHOLE fruit, or even an UNSWEETENED juice. If you like this drink it as a food–don’t consider it a medicine.
