What’s Worse-Carbs or Seed Oils? Understanding a High-PUFA Diet

I have been reading some of Tucker Goodrich’s analysis of the role of seed oils in modern diseases and I believe that he presents a compelling case. I provide a link to his title article on this subject below.

My simple takeaway from reading many of the papers is that (a) excess carbs is bad, (b) excess Linoleic Acid (from seed oils) is bad, but (c) together they are much worse and probably toxic, particularly when a person loses blood glucose regulation.

Tucker has also written an older article “Omega-6 fatty acids: the alternative hypothesis for diseases of civilization” that ties a lot of evidence together in an easier to consume format and with less jargon. It is well worth reading.


We have good evidence that consumption of excessive carbohydrates leads to insulin resistance, hyperinsulinemia, T2D and related diseases.

We have Robert Lustig showing that the carbohydrate, sugar, by itself is bad.

We have Tucker and others showing how seed oils are particularly bad for our health.

If you add those two/three ingredients together, you get modern processed food.

While neither a high carb diet nor seed oil consumption is good, they seem to work particularly well together to accelerate your decline into early death.

You don’t need me to tell you what to do.

20 percent of your body fat could be industrial lubricant

Some interesting things about fat that should interest you:

  • Modern ‘vegetable’ oils are basically detoxified industrial lubricants made by chemical reactions in refineries.
  • If like many people, you eat a diet high in packaged, junk or take-away foods, then your own body fat could be 20% omega-6 polyunsaturated vegetable oil (PUF) instead of just a few of percent.
  • The recommended daily intake of omega-3 PUF for an adult is less than 2g.
  • The body best uses omega-3 when balanced with omega-6 – so you should have less than 2g omega-6.
  • The average takeaway consumer eat around 100g of PUF per day – mostly omega-6 – yes that is 50 times what you need/want.
  • PUF can take 4-5 years to cycle out of body fat in a weight stable individual.
  • PUF is preferentially consumed by the body when losing weight – crash dieting can liberate harmful levels of omega-6 PUF.
  • Omega-6 PUF promote inflammation  – so what?  Heart disease, liver and other organ damage, stroke, arthritis, cancer.
  • Omega-6 levels in breast milk reflects the mothers diet.  If a mother is eating a lot of PUF, then she is feeding proportional amounts of PUF to her baby.

Should this be in your diet?

Linoleic acid reduction in recommended diet

We have updated our food guidance to further reduce the amount of Linoleic Acid (LA) consumed through the recommended diet.

What is LA?  LA is a omega-6 polyunsaturated fat (PUF) predominately from grains/seeds such as soybean.  LA is normally low in traditional diets and high in modern manufactured foods.  It is also high in animals fed a diet of grains through intensive farming. Continue reading
