Is a low-fat diet better for your heart?

You can bet your ticker it's not – but you won't learn the truth by reading the latest study to hit the mainstream media.

The study, funded by the National Institutes of Health and published in the Journal of the American Dietetic Association, compared the maintenance phases of three diets: the low-carb, high-fat Atkins diet, the more moderate South Beach Diet, and the low-fat Ornish vegetarian diet. 

It found the Atkins diet to be least heart-friendly.

You might think they followed hundreds or even thousands of people on these diets for years at a time. But it turns out they looked at 18 people, each of whom tried each diet for four weeks, with a four-week "washout" period in between each one.

That's it – just 18 people for four-week periods. Do you feel cheated yet? I know I do. 

What's more, they based their findings on cholesterol levels and blood vessel dilation measurements in the arm.

The trouble is that those changes in blood vessel dilation can be caused by any number of things, such as a problem in the adrenal glands. In a group as small as 18 people, all it takes is one person experiencing one of those causes to skew the results one way or another.

Dr. Atkins was in many ways a visionary. He had the right idea when the declared that carbohydrates, not fat, are the enemy. Especially those refined carbs in all our processed foods. And he was bold enough to speak out against low-fat madness at a time when it was very unpopular to do so.

But there is still so much more to a diet than just fats versus carbs, just like there's more to a diet than caloric intake. Nutrients and minerals play a crucial role in our bodies, yet few dieters consider that when planning their meals.

For example, our potassium to sodium ratio should be at 7 to 1. But most people take in far less potassium because our processed foods are packed with sodium. And a potassium deficiency can have a direct impact on your heart, no matter what kind of diet you stick to.

Correcting this potassium deficiency can also help you put a permanent end chronic fatigue. I've outlined a simple, 90-day cure for fatigue in the June issue of Health Revelations.
