New study reveals that carbs, not fats, result in diabetes and heart diseases

A new study conducted on 16 middle-aged, obese adults for 21 weeks and now published in the Nov. 21 journal PLOS ONE has revealed that the ancient concept that fats cause diabetes and heart disease can be thrown out of the window.
The study was funded by a grant from the Dairy Research Institute, the National Cattlemen's Beef Association, the Egg Nutrition Center, and the Robert C. and Veronica Atkins Foundation and the researchers have confirmed that the funders did not have any role in the design of the study or the decision to publish the findings.
The study has apparently shown that doubling the saturated fat in a person's diet does not drive up the levels of saturated fat in the blood but the carbohydrates does. As per the study, it was the carbohydrates that were to blame for increased levels of a type of fatty acid linked to heart disease and type-2 diabetes.
The general belief till now was that saturated fats from meat and dairy products were the main culprit in promoting heart disease and most health authorities never doubted this but maintained this stance.
But, in recent years, scientists have observed the ill effects of totally replacing saturated fat with carbohydrates, particularly the simple carbs that are found so commonly in processed foods.
Based on a 2009 analysis that was published in the American Journal of Clinical Nutrition it was found that replacing saturated fats with carbs had no benefit towards reducing heart diseases. However, replacing the bad fats with polyunsaturated fats found in fish, olives and nuts did.
