Speaker Q&A

1. Question:

If GM soybean oil contains low linoleic acid, but still causes obesity and insulin resistance (one of which they claim is not the case), what is the mechanism behind this?

​

​

Answer:

As they noted in the original paper, there are several different factors at play. One of them was that they thought coconut fats may be protective.

 

They also found negative effects from olive oil with a similar fat composition to Plenish (GM soybean oil), which further suggests that linoleic and oleic may lack some protective element.

 

The study that motivated this one, Alvheim 2012, found DHA was protective, so there are definitely interplays between different fats that need to be explored.

2. Question:

Can vitamin E supplementation reduce the weight gain effects of linoleic acid consumption by reducing oxidation within the mitochondria[*]?

 

Answer:

It doesn’t appear likely. In the Plenish GM soybean oil paper, the most fattening diet (soybean oil) had the highest levels of vitamin E.

 

Vitamin E doesn’t enter the inner mitochondrial membrane where damaging oxidation occurs in the mitochondria. Some studies find that vitamin E worsens things, as it can accelerate the oxidation of LA.

3. Question:

What’s the best way to get rid of PUFA in fat stores?

 

Answer:

Cut consumption, intermittent fast, and exercise aerobically when fasted to burn fat stores. Even walking daily before breakfast can have a huge impact.
