Systematic Review Finds No Grounds for Current Guidelines on Fat
Sugar, Not Fat, Drives Heart Disease
In the 1960s, British physician John Yudkin was among the first to challenge Ancel Keys' hypothesis that saturated fat caused heart disease by raising cholesterol, stating that SUGAR is the culprit in heart disease—not saturated fat.
In more recent years, Yudkin's work has been proven prophetic—and far more accurate than Keys' ever was. For example, a 2010 study published in
theAmericanJournal of Clinical Nutrition found that when you replace saturated fat with a higher carbohydrate intake, particularly refined carbohydrate, you exacerbate insulin resistance and obesity, increase triglycerides and small LDL particles, and reduce beneficial HDL cholesterol.The authors state that dietary efforts to improve your cardiovascular disease risk should primarily emphasize the limitation of refined carbohydrate intake and weight reduction.
Courtesy of the low-fat myth taking firm hold, this is the polar opposite of what actually occurred over the past half century. While saturated fat consumption was dramatically reduced in most people's
diet, refined carbohydrate intake dramatically increased. Today, refined fructose is added to virtually every kind of processed food and beverage on the US market.One of the reasons for all this added sugar is because when you remove fat, you lose flavor. So sugar is used to add flavor back in. Consumption of harmful trans fat (which for decades was touted as a healthier alternative to saturated animal fat) also radically increased, starting in the mid-1950s.
Replacing Saturated Fats with Carbohydrates Has Led to Elevated Disease Risks Across the Board
In the final analysis, it seems clear that one seriously flawed hypothesis gaining foothold in the minds of the medical establishment
has ledto a decades-long snowball effect of dietary recommendations that have both altered the food supply for the worse, and led to an avalanche of otherwise avoidable chronic diseases.Evidence of this was recently highlighted in an excellent editorial in the Heart. In it, research scientist and doctor of pharmacy James J. journalOpen DiNicolantonioreviews the cardiometabolicconsequences of replacing saturated fats with carbohydrates, which includes the following:
Shift tooverall atherogenic lipid profile (lower HDL, increased triglycerides and increased ApoB/ApoA-1 ratio) Increased risk of coronary heart disease, cardiovascular events, and death from heart disease and increased overall mortality (all causes) Increased thrombogenicmarkers Increased oxidized LDL Increased inflammation Reduced HDL Impaired glucose tolerance, higher body fat, weight gain, obesity, and diabetes Increased small, high-density LDL particles Increased risk for cancer
