New study: High-fat food is good for people with diabetes

High Fat

There is no reason to fear fat anymore. High fat food is even good for people with diabetes, according to a new high-quality Swedish study of 61 patients:

  • Diabetes patients randomized to a high fat (20% carb) diet improved their blood sugar, cholesterol and could reduce their diabetes medications.
  • Patients randomized to conventional (obsolete) low fat advice did not improve anything.

No surprises. Previous trials have shown similar results: Fat is good for the health of people with diabetes. So why do most people with diabetes still get the failed old low fat advice? By now it should be borderline criminal.

The study

    Thank you for this- emailing it to my (diabetic) father now! :)

    Nothing to do with diet but I'm going to miss the last episode of "The Bridge" next weekend as I'm away. I just want to say darn you Swedes (and Danes) and your cop shows, I'm totally hooked on this. I can't help looking at what people are eating though. In one episode Saga microwaved a pizza. So much for LCHF Sweden! ;)

    (A TV show full of murders, corruption and unhappy families, and all I can think about is low carb diets...oh dear...)

    What were the respective protein and fat percentages of the two diets?

    "The patients were randomised to either an LCD or a
    traditional LFD, both with an energy content of 6,694 kJ/day
    (1,600 kcal/day) for women or 7,531 kJ/day (1,800 kcal/day)
    for men. Randomisation was not stratified and was based on
    drawing blinded ballots. The LCD had an energy content
    where 50 energy per cent (E%) was from fat, 20 E% was from
    carbohydrate and 30 E% was from protein. The LFD had a
    nutrient compo sit ion that was similar to that tradition ally
    recommended for the treatment of type 2 diabetes in Sweden,
    with 30 E% from fat (less than 10 E% from saturated fat), 55–
    60 E% from carbohydrate and 10–15 E% from protein."

    Well, duh!

    There is another news in Medical express:

    Reading further, I now wonder how much better the subjects would have done on a higher-fat, lower-carb ketogenic diet. The carb content was still much higher than I consume to prevent the "Type II Diabetes" that has plagued my family.

    I've been looking for a report on this study in my local newspaper and on Huffpo - nothing so far. But my local paper reported that high HDL levels are not associated with any health improvements and that coffee drinkers live longer - both reports based on epidemiological "Studies." Sigh.

    Seriously, 'high quality study' and '61 patients' in the same sentence? They should really be repeating the study with a much larger population sample before recommending this diet to anyone. Especially taking into consideration that diabetes in itself is a huge risk factor for cardiovascular disease, and a high-fat diet will only increase that risk.
  9. Jack
    Sue, you are right about the study being too small but very wrong about high fat diet increasing the risk for cardiovascular disease. Start reading, it's carbs which increase that risk not fat. That theory is dead and buried.
