"This study, published in the American College of Cardiology Journal, compared 80 people with an average age of 55 on low-carb/ high-protein and fat diets with 80 people enrolled in a Miami heart study and not on a special diet.

“They had the same level of disease risk,” Fialkow said. “The study found no increased progression in either group.”

Researchers concluded there was no association between cholesterol levels and plaque burden in either group. So, as long as people do not consume lots of sugar and carbohydrates, they may not be at risk for heart disease, even if they have high cholesterol."
