Dr. Oz says he makes a breakfast drink for himself many mornings that he calls his green drink.

What's in Dr. Oz's green drink?
2 cups spinach
2 cups cucumber
1 head of celery
1/2 inch or teaspoon ginger root
1 bunch parsley
2 apples
Juice of 1 lime
Juice of 1/2 lemon
After everything is combined in a blender, this recipe makes 28 to 30 ounces¿about three to four servings. Oprah takes a sip and is pleasantly surprised. "It's a glass of fresh," she says.

Dr. Oz's second drink might not be as pleasant, but it's still important¿a shot of cod liver oil. "First of all, cod liver oil has the right kind of vitamin D in itvitamin D3. That's why people who live in the north lands who don't get any sun at all can still survive. It's got the healthy fats that you want in it," Dr. Oz says.
