Bad Advice

http://cholesterol.about.com/od/lipoproteins/a/smalldenseldl.htm

Wanted to share with you all this interesting example of the twisting and spinning that goes on with nutritionists giving advise. The above article is talking about the small dense LDL which appears to be the issue with cholesterol. She lists the things that cause small dense LDL as:

  • High Carb intake
  • Trans fat intake
  • Uncontrolled diabetes
  • High Triglycerides, low HDL
  • Metabolic syndrome

So what's the advice to reduce? Two of the items on


  • 'Lower your carbohydrate intake in addition to your saturated fat and trans fat intake' Why saturated fat? It's been showed to increase HDL and lower triglycerides and raise the level of large fluffy LDL so that should reduce the small dense LDL according to her own list of causes.
  • 'Lose weight... by following a diet low in fat and carbohydrates'? Why low fat? The causes would indicate yes, low trans fat, so avoiding vegetable based oils and hydrogenated oils, sure, but do you really need to avoid the other fats?

We are SO intrenched in this idea that fats are bad that even when the science shows that saturated fat is actually beneficial, we continue to advise low fat diets.

Weird.

  2. So true. It amazes me that people stick to the 'saturated fat is bad' line no matter how much evidence there is to the contrary!

    Thanks for reading!
