For more than half a century, the conventional wisdom among nutritionists and public health officials was that fat is dietary enemy number one – the leading cause of obesity and heart disease.
It appears the wisdom was off. And not just off. Almost entirely backward.
According to a new study from the National Institutes of Health, a diet that reduces carbohydrates in favor of fat – including the saturated fat in meat and butter – improves nearly every health measurement, from reducing our waistlines to keeping our arteries clear, more than the low-fat diets that have been recommended for generations. "The medical establishment got it wrong," says cardiologist Dennis Goodman, director of Integrative Medicine at New York Medical Associates. "The belief system didn't pan out."
