Dr. Fuhrman's nutrient-packed "Skinny Shake" as seen on The Dr. Oz Show

In preparation for my recent appearance on The Dr. Oz Show (you can watch online here), I was asked to share a recipe for a healthful drink that would support weight loss efforts and promote detoxification – something satisfying and delicious while low in calories; most important to me was that this drink would be packed with disease-fighting nutrients.

I chose a simple blended frozen drink of whole strawberries and pomegranate juice with ice plus a squeeze of lemon for a tangy flavor. Why strawberries and pomegranate juice? I did not make those choices arbitrarily – these are powerful foods with several human studies to substantiate their profound benefits.

Antioxidant phytochemicals:

  • Anthocyanins (the most abundant antioxidants in berries) provide antioxidant protection on their own, plus they increase the production of cells’ own antioxidant enzymes.1 A 1.5 cup serving of strawberries increased antioxidant capacity in the blood of human subjects, building protection against oxidative damage.2
  • Pomegranate contains a unique antioxidant called punicalagin; it is the most abundant antioxidant in pomegranate, responsible for more than half of the antioxidant activity of pomegranate juice.3 Pomegranate juice has been found to reduce oxidative stress markers in healthy humans.4

Detoxification:

  • Ellagic acid, an antioxidant derived from berries and pomegranate interacts with a protein called Nrf-2 to increase expression of the body’s natural detoxification enzymes.5

Anti-cancer effects:

  • Strawberry and pomegranate extracts slowed cell growth and induced cell death in human cancer cells from several cancer types.6-9
  • Pomegranate and strawberries are both anti-angiogenic – strawberry extracts help to prevent growing tumors from acquiring a blood supply – preventing those tumors from receiving the nutrients that would allow them to grow larger.10-13
  • Pomegranate is one of the few foods (mushrooms are another) that contain natural aromatase inhibitors – this means that they inhibit the production of estrogen, which can reduce breast cancer risk.14
  • Strawberries and pomegranate have anti-inflammatory effects that may protect against cancer and other chronic diseases.5,15,16
  • Patients with precancerous esophageal lesions ate strawberries each day for six months.  The results were amazing – 29 out of the 36 patients in the study experienced a decrease in the histological grade of their lesion – this means that the progression toward cancer began to reverse, and the risk of the lesions becoming cancerous had decreased.17 

 

Cardioprotective effects:

  • Higher strawberry intake is associated with reduced risk of death from cardiovascular disease.18
  • Human trials have found that daily consumption of strawberries decreases total and LDL cholesterol, and pomegranate phytochemicals reduce LDL oxidation (a contributor to atherosclerotic plaque development).19-22
  • Strawberry and pomegranate phytochemicals have blood pressure-reducing properties.23-25
  • In a study of patients with severe carotid artery blockages, after one ounce of pomegranate juice daily for one year, there was a 30 percent reduction in atherosclerotic plaque. In striking contrast, in the participants who did not take the pomegranate juice atherosclerotic plaque increased by 9 percent.22

Anti-diabetes effects:

  • Strawberry and pomegranate phytochemicals have actions on certain digestive enzymes that can result in reduced glucose levels following a meal.26
  • Ellagic acid, which can be derived from berries or pomegranate, reduced secretion by fat cells of an inflammatory molecule that is thought to contribute to insulin resistance.27
  • Adding strawberries to a meal was shown to reduce the insulin response in overweight adults.15

Looking at these effects all together, it is astounding what these foods can do for our health. The “Skinny Shake” has much more to offer than taste and satisfaction with minimal calories. Berries (and pomegranate) make up the second ‘B’ in G-BOMBS, my list of super foods with good reason!
