Forty Years of Dietary Advice Down the Drain – Buh-Bye!

Dr. Axel Sigurdsson is a cardiologist who focuses his blogging on cardiovascular disease and lipid disorders. I bet he agrees with me that dietary saturated fat is not the malevolent force we were taught in medical school.

From his blog:

“The [PURE study] suggests that placing carbohydrates at the bottom of the food pyramid based on their effect on blood cholesterol was a mistake. In fact, the data show that replacing dietary carbohydrates with different types of fat may improve lipid profile.

In an interview on Medscape, Dr. Mahshid Dehghan, the principal author of the abstract said: “To summarize our findings, the most adverse effect on blood lipids is from carbohydrates; the most benefit is from consumption of monounsaturated fatty acids; and the effect of saturated and polyunsaturated fatty acids are mixed. I believe this is a big message that we can give because we are confusing people with a low-fat diet and all the complications of total fat consumption, and WHO and AHA all suggest 55% to 60% of energy from carbohydrates.”

Today, most experts agree that diets high in saturated fatty acids or refined carbohydrates are not be recommended for the prevention of heart disease. However, it appears that carbohydrates are likely to cause a greater metabolic damage than saturated fatty acids in the rapidly growing population of people with metabolic abnormalities associated with obesity and insulin resistance.”

PS: A diet naturally high in monounsaturated fat is one you may have heard of: the Mediterranean diet. A low-carb Mediterranean diet is the cornerstone of Conquer Diabetes and Prediabetes.

  1. None of this matters. The literature has no requirement that you cite relevant and exculpatory evidence or if it does, it doesn’t enforce it. Who’s going to cite this. Not anybody who publishes in Circulation which is owned by AHA. IMHO

    I have eaten a well balanced diet (all food groups) and lived a healthy active life style for the past 40 years I have had type1 diabetes. I have perfect weight and perfect heath with zero complications.

    Your comment should read that “carbohydrates are likely to cause a greater metabolic damage than saturated and polyunsaturated fatty acids”, if you are basing it on the PURE study. And given that most of the PUFA consumed comes packaged with highly refined processed foods and tend to be easily oxidized and thus rancid, the emphasis should probably be on reducing PUFA from these sources.

    Ok, I was a complete vegitarian for many years -lots of real exercise long distance bicycle riding. Weight low. Now T2 Diab. A1c 8.2 On Low carb- high fat diet 1 year . A1c=5.1 Bs range 87 -114. All numbers ratios, Prticle size etc. very good EXCEPT total Cholesterol. Weight loss 6 lbs. Concerned about China Study and animal Pr+. 10 brussel sprouts, broccoli etc. puts my BS up in the 130+ range 4 hrs after. What is going on here?

  5. I love it when a patient asks me what I think about their cardiologist’s dietary advice (usually AHA based). There’s usually a long, silent pause before I answer……
