If you watch Fox News very often like I do, you probably know which companies pay the most for advertising. It's the drug companies. The network runs one drug ad after another. And it's become quite obvious over the years that Fox News is anything but "fair and balanced" when it comes to medicine. The network rarely talks about nutrients in a positive light. And it almost never targets a drug with negative news. I understand: They don't want to irritate their sponsors. As a result, when it comes to reporting on nutrients, I always look at their stories with some skepticism.
Take resveratrol, for instance. This nutrient is one of Fox News' favorite targets. It has done a few positive segments on the nutrient through the years. But most of these stories have a doctor that rebuts the claim or gives a lot of caveats. Then they report every negative story about the nutrient that comes along – without any rebuttal. One of those came out recently. This report said that resveratrol may hinder the effects of high-intensity interval exercise.
According to Fox News, the study followed "16 people who exercised less than three hours per week at the beginning of the study who began performing high-intensity interval training (HIIT) three times per week for four weeks. HIIT consists of quick, intense bursts of activity followed by short, low-intensity recovery periods. This type of exercise reportedly increases heart rate and burns more fat in a shorter amount of time, compared to steady-state workouts.
"While the participants engaged in HIIT, they took daily doses of either resveratrol or a placebo.
"Scientists observed that the placebo group showed an increase in some of the benefits associated with physical activity, while the group taking resveratrol did not see their physical fitness improve."

This was a very small study and covered a very short period of time. In fact, 16 people split into two groups followed for four weeks is laughable. That's way too small a sample and too short a period to conclude anything. Plus, what did they conclude? The news report says the "scientists observed … an increase in some of the benefits." But what were they and how much? So it's not a great study to begin with. But the news report discussed none of this.
With that said, let's give the study the benefit of the doubt and say the results are accurate. They could be. Would this create a problem for resveratrol? Other than the negative media attention, the answer is no. Let me explain.
We know that resveratrol mimics naturally occurring amino acids. These amino acids protect our cells from genetic damage. In fact, a recent study found that resveratrol mimics the amino acid tyrosine. Tyrosine is one of these naturally occurring amino acids that bind to enzymes. When resveratrol binds to the enzyme TyrRS, it activates the enzyme and causes it to move to the cell nucleus. Once it's in the cell nucleus, it helps protect chromosomes' DNA from genetic damage.
So what does this have to do with the exercise study? A lot. First, tyrosine is a very popular supplement among athletes. It helps them exercise longer and harder. Why? Because it helps keep the cells from breaking down during exercise. They don't become strained as quickly. Since resveratrol has a similar impact, this exercise study shows that those taking the nutrient could have gone longer and harder than the placebo group, but were hindered from doing so by the parameters of the study.
Let me explain it another way. High-intensity interval exercise works because it breaks down the body faster and forces it to rebuild muscle and burn fat faster. It's a great form of exercise. It's very possible, even likely, that the resveratrol was protecting these participants from the extremes of this particular exercise routine. Had the study or the exercise regimen gone on longer, the researchers would have seen that the resveratrol was providing a major benefit for the exercisers. And they would have come to a different conclusion.
So if you're looking for fantastic protection against cell damage (which can lead to aging, cancer, and other illnesses), then make sure you're taking resveratrol every day. I recommend Advanced Resveratrol Formula. And if you want the inside truth about nutrients, stay connected with your Nutrient Insider. Fox News certainly won't give it to you.
