Most of us have received an e-mail or seen an advertisement endorsing the Dr. Oz or Oprah diet using acai (ah-sigh-ee) or resveratrol. When I see their faces, I so want to believe that there is a magic juice to make me thinner, younger looking and more energetic. Now if it was that easy, it would be on my shelf already. I still want to believe.
Is there such thing as an Oprah or Dr. Oz diet or secret weapon?
No, Both Dr. Oz an Oprah are pursuing legal action against the companies that use their name and likeness to dupe people into ordering products that they do not specifically endorse. See Oprah: http://www.oprah.com/article/health/nutrition/20090105_orig_acai.
The companies seem to primarily originate in China and will often try to get your credit card so they can charge you on a monthly basis. Even if it says “free trial” and just pay for shipping. Don’t do it! It is all a scam to get your credit card, and they will continue to charge your card monthly.
What about other juices sold in the United States by individuals or in stores?
There are many products sold by individuals, most notoriously MonaVie, that are part of a multilevel marketing strategy. They rely on many distributors with only a very few at the top making lots of money, as these bottles are very expensive. Their product claims to contain acai and other juices, but they do not release in what amounts, as that is considered proprietary information. I am very wary of these products because there is so much financial incentive in their pyramid system. You can look at their income discloser statement: http://74.125.47.132/search?q=cache:VKOAObEHkKQJ:media.monavie.com/pdf/corporate/income_disclosure_statement.pdf+monavie+disclosure&cd=1&hl=en&ct=clnk&gl=us&client=firefox-a.
Many people claim to get tremendous benefit, which could be from the juice or even placebo, but it is important to know how these things work financially. Please check with the Better Business Bureau (http://www.bbb.org/) before buying any of these products from individual companies. It is very difficult to even research, as you will find so many sites that claim to be giving information but are actually pushing their own product. I would like to see some randomized double blind trials to support their claims.
These products are grouped as antioxidants. What is an antioxidant and how do they help us?
Our body produces something called free radicals, which are bouncing reactive oxygen particles that can damage our DNA, proteins or fat. This can lead to cancer, heart disease and aging.
We use antioxidants to suck up the free radicals and prevent the damage that could be caused to our organs. Antioxidants are mostly found in nature in fruits, vegetables and nuts. Dark cocoa is also a great source for antioxidants. Antioxidants are very important, and we really don’t know the full extent of their potential benefits.
Tell us about the specific antioxidants that these Web sites are targeting: acai and resveratrol.
These are both very good antioxidants. ORAC is the Oxygen Radical Absorbance Capacity (ORAC) and is a method of measuring antioxidant capacities of different foods. This is a relatively new term, and you can compare different antioxidant properties here: http://www.ars.usda.gov/is/pr/2007/071106.htm. An apple with skin has a very high amount of ORAC.
Resveratrol comes from grapeskin and does appear to have some cardiac benefit, and perhaps some anti-aging properties. Click here to learn more: http://www.mayoclinic.com/health/red-wine/HB00089. Researchers think that it is one of the ingredients in red wine that makes it so heart healthy. However, we need more studies in humans.
Acai berry come from Brazil and is rich in antioxidants as well as healthy fats. We don’t have a lot of data to support drastic health change from it, but it does look promising. Again, not enough studies in humans yet.
However, there was a recent study comparing the amount of antioxidants in acai to other juices. Pomegranate juice, red wine and concord grape juice all scored higher in antioxidants than the acai juice. Study link: http://www.ncbi.nlm.nih.gov/pubmed/18220345?ordinalpos=11&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum.
Interestingly, in another study, cocoa scored higher than red wine! Study link: http://www.ncbi.nlm.nih.gov/pubmed/14640573?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DiscoveryPanel.Pubmed_Discovery_RA&linkpos=2&log$=relatedarticles&logdbfrom=pubmed.
The bottom line is to eat more fruit and vegetables, and consider one of these supplements to help you increase your antioxidants. Americans eat way too many empty calories, meaning food with little nutritional value. Super juices like acai and resveratrol won’t likely hurt you, they may really help you, but don’t break the bank doing it.
Thanks for checking in,
