Antioxidants Don't Prevent Cardiac Disease

Tip to EverythingHealth readers: Quit wasting your money on "antioxidants". The evidence is clear that Vitamin E, B-vitamins and Folic Acid do not prevent heart attack or stroke.

It's easy to see why there was a buzz about these antioxidants and why millions of people have spent $billions of dollars on these vitamins. The LDL (bad) particle of cholesterol needs to be "oxidized" to be taken up into the artery wall. People got interested in Vitamin E, which circulates in the LDL particle and thought it might be protective against oxidation. Beta Carotene also circulates so people thought it might prevent cancer and heart disease.

That lead to numerous prospective, randomized trials in both men and women in high risk and low risk populations. They took Vitamin E, Vitamin C, and beta carotene alone and in combination. There were huge trials over 5 years that showed NO BENEFIT.

We also got interested in homocysteine because high levels in the blood were associated with vascular disease. We thought that lowering homocysteine would prevent disease. B vitamins lower homocysteine so people started taking B vitamins and folic acid as a way to prevent disease. There have been at least 7 good trials that show NO BENEFIT whatsoever from taking these vitamins compared to placebo.

We can put this issue to rest now. Get vitamins from a healthy diet of fruits and vegetables. Go to farmers markets and buy organic when possible. Aim for 5 fruits and vegies a day. Save your money that you would spend on supplements. Use that money for organic foods.

Antioxidants fight free radicals and have nothing to do with cardiac. I wonder where the ideal of cardiac came about.

Personally, I think people who purchase supplements are wasting their money. The FDA doesn't monitor them, so there is no telling just how accurate the potency is or what is exactly are in these supplements.

The FDA recently found Sibutramine, Rimonabant, Phenytoin,Phenolphthalein, and Bumetanide in some weight loss supplements. It makes you wonder...

I remember when advertising was saying that Margarine was better than butter ....wrong , very, very wrong . Also about oil . Olive oil ...very good for you as well as coconut oil ...just look at the longevity in the Pacific and the Mediterranean countries .
Our food are completely full of pesticide and whatever taking vitamins is not bad it as a "placebo " effect that is very good .....all those trials that are mentioned in the blog are most likely done or PAID by the pharmaceutical CO.

Everything is on this hearth to makes us healthy...but money , greed Leeds us to go along with the "fairy tales" that the pharmaceuticals are feeding us . said...

I agree. Get your vitamins, minerals, antioxidants and whatever else you need for good health from food.

These studies highlighted in your post show that synthetic supplements are essentially worthless and in fact, may do you more harm than good.

The key is to take vitamins made only from food. There are no negative side effects and your body knows exactly what to do with the nutrients.

The person who believes they get everything they need for good health, strictly from their diet, is rare indeed. A whole-food multi is a nice option for those who are busy and need the convenience.

According to the American Heart Association, heart disease is the nation's single leading cause of death for both men and women. At least 58.8 million people in this country suffer from some form of heart disease.
And on the whole, cardiovascular diseases (the combination of heart disease and stroke) kill some 950,000 Americans every year.
Still, there are many misconceptions about heart disease: "The biggest misconception is that heart disease only happens to the elderly," said Elizabeth Schilling, CRNP with the Center for Preventive Cardiology Program at the University of Maryland Medical Center.
In fact, according to the American Heart Association, almost 150,00 Americans killed by cardiovascular disease each year are under the age of 65. And one out of every 20 people below the age of 40 has heart disease.
So, it is now a wise decision to keep a constant monitoring of your health. Why to take a chance if we have the option. I was in the similar misconception that heart disease are far away waiting for me to get aged. But to my surprise, I was found to be having a calcium deposit in my coronary arteries. I need to have my advance diagnostic scans due reassure whether something really deadly is waiting for me. Though it was some dreadful going on in my life, but I never felt any kind of discomfort in advanced diagnostic facility. They were having some of the latest diagnostic equipments and non invasive techniques which made me feel safe.
