“Dr Oz: Antioxidants”. Fighting The War On Cancer With Prevention.

What are Antioxidants?The Dr. Oz Show has featured what Dr. Oz called his “three most important cancer fighting All Star Antioxidants”.  He said antioxidants found in fruits and vegetables can be our body’s weapon against cancer.  Together with guest, Dr. William Li, MD Cancer Researcher, President of The Angiogenesis Foundation, they explained “what are antioxidants and why are they good for you?”

Dr. Li says antioxidants are natural protective molecules that mother nature has laced into a large number of foods that protect our DNA in our healthy cells from damage. That damage involves the formation of chemicals called Free Radicals, toxic byproducts of cell metabolism. Many antioxidants stop the free radicals from forming, thus stopping damage to our cells and reducing our risk of developing cancer. Many have anti-angiogenic properties which mean they can starve cancers by preventing the blood vessels which feed cancer tumors. No blood vessel, no cancer!

Dr. Oz had once explained that if you cut an apple in half it will turn brown because of the oxidation in the air. That browning represents the damage that goes on in our bodies through our oxidation processes. But if you dip the cut apple in orange juice, it doesn’t turn brown. The anti-oxidants in the food we eat protects the DNA in our cells like the orange juice protects the apple from browning.

Dr. Oz explained that when DNA reproduces itself it makes a perfect copy. If our DNA is damaged, it makes a perfect copy of our damaged DNA.  It continues making copies of the damaged DNA until eventually they develop into rogue cancer cells. The chemical  pollutants in our environment such as pesticides, cigarette smoke, and chemicals produced by fried foods, do damage to our DNA and the antioxidants in our foods is what mother nature gave us to help protect our cells from that damage.

Dr. Oz said his top three were carotenoids, isothiocyanates, flavonoids but as Dr. Li said there are literally thousands of different types of antioxidants, several of which have been the subject of many Dr. Oz Show segments.  The chart below presents a few.

Without having to remember or pronounce any of the names, take a look at the “Sources” and “Benefits” and you will see why Dr. Oz keeps saying over and over again “eat 5 or more servings of fruits and vegetables a day and eat a rainbow variety of colors.

The USDA has a list of foods reported to contain the highest amounts of antioxidants. TheRightTrak.com has that list by Food Group and a list by Highest Content.

As a nutrient calculator The RightTrak.com can also calculate your BMI and your Recommended Daily Allowances(RDA) for over 30 nutrients. You can select a variety of foods and The RightTrak will add up the nutrient values of your selected foods such as vitamin A, vitamin C, vitamin E, vitamin K, folate, beta carotene…and more.  The RightTrak will turn Green if those allowances are met or Red if those allowances are not met.

How can we be sure that we are getting enough of these protective compounds?

  1. I PRAY FOR MORE DOCTORS AND SCIENTISTS TO LOOK INTO FOOD FOR CURES OF VARIOUS TYPES OF CANCER. TO SEE ADULTS AND MORE THAN THAT CHILDREN BEING EATEN UP BY CANCER IS A LACK OF FOCUS ON GOD FOR THE ANSWERS TO OUR PROBLEMS. IT SEEMS THAT MOST AVENUES OF SO CALLED CURES ARE HOOKED UP WITH MAN MADE DRUGS (CHEMO) THAT GO AGAINST NATURE, AND DESTROY THE LIFE IN US, GOD GIVEN ABILITIES FOR THE HEALING OF THE BODY THROUGH THE VARIOUS ORAGANS AND CELLS IN OUR BLOOD AND IMMUNE SYSTEM. PRAYER HELPS MORE THAN ANYTHING AND LISTENING TO GOD WILL HELP US FIND THE CURES. THESE ARTICLES ARE MOST ENCOURAGING TO ME..BLESSINGS, NANCY
