Dr Oz: Vitamin A Increases Men’s Risk For Prostate Cancer
Dr. Oz has always recommended foods with powerful antioxidants because of their ability to prevent cancer and protect the body from other diseases, but new research has put all of that into question. Could the antioxidant supplements you are taking be causing you more harm than good?
Dr Oz: Are You Overdosing On Antioxidant Supplements?
Dr. Russell Greenfield believes it is absolutely possible for antioxidant supplements to cause us more harm than good because we are simply getting too much of them. He admits, like everyone else, he bought into their powerful benefits. Dr. Greenfield said he has taken antioxidant supplements for years and often recommends them to his patients, but those could end up having the reverse effect. He was clear to express that the concern lies in antioxidant supplements, not healthy fruits and vegetables that naturally contain antioxidants. Dr. Greenfield told Dr. Oz that taking too much of something, even antioxidant supplements, can cause harm by getting rid of too many free radicals in the body. The question becomes, how many free radicals are good to have in the body and how much should we be getting rid of?
Dr Oz: Smoker’s Cancer Risk Increases With Beta Carotene
Dr. Russell Greenfield explained that not all antioxidant supplements are created equal. The most common way people are getting antioxidants in supplement form is via a multivitamin. Dr. Greenfield does not suggest avoiding antioxidant supplements entirely, but he did say we need to take a step back and take a closer look. He said it is about reading the labels and understanding how much of each antioxidant you really need because too many people are overdosing on antioxidant supplements.
Vitamin A – Vitamin A provides Beta Carotene, which is found in healthy foods like carrots, so taking it should be good for us, but not in the case of a smoker. If a smoker takes too much Beta Carotene it will actually drive certain cancers, putting those people at greater risk.
Vitamin C – This is another questionable vitamin when taken as a supplement. Dr. Greenfield said there is simply no good data that suggests Vitamin C in supplement form will prevent cancer, so he said it is best to stick to foods as your best sources for Vitamin C.
Vitamin E – Taken in too high a dose in supplement form, Vitamin E has been shown to increase a man’s risk for prostate cancer.
Selenium – In high doses, Selenium has been shown to increase your risk for skin cancer up to 25%!
Dr Oz: Antioxidants “Added” To Processed Foods
Dr. Russell Greenfield is very bothered that we are now seeing antioxidants as an added ingredient in many packaged foods we buy at the grocery store. He said this leads to taking in a larger amount of antioxidants though our diet and if you add that to taking supplements it could be putting your health at risk. Dr. Greenfield added another concern is that these added antioxidants are found in highly processed foods, which are the types of foods we should be avoiding in our diets.
Dr Oz: Vitamin A New Suggested Dose
Dr. Oz offered his personal recommendation if you are taking an antioxidant supplement. He said to purchase a low-dose multivitamin that provides the same amount of nutrients that you would get if you had eaten the right foods. Dr. Oz said taking more than that will end up being a pharmaceutical dose, which you do not want or need in your body. For the first time, he is lowering his recommendations after seeing the results of the powerful new research that Dr. Russell Greenfield has shared today.
Vitamin A – Dr. Oz’s new suggested dose is 2,500 IUs per day
