More by Jeff on That CVD Study


Jeff Novick does a follow-up on the study I mentioned in that previous post, and promises even more about it in the future. As it turns out, once you read the entire study you see what was really concluded.

I suggest you read  the entire thread, but here's a snippet from one of his posts:

I agree 100% with most all of it including... 
no to - - juicing- - (most) supplements- - coconut oil- - eggs- - hi fat diets
and 
yes to..- -veggies, - - protein from plant foods- - (fruits)/berries.  

The question is on nuts, which we do allow in moderation but they are not recommended for weight loss, which is exactly what the paper recommends, limiting intake to one ounce a day (30 gm) and that "Moderate quantities are required to prevent caloric excess." No argument there. 
The real question is liquid vegetable oils like corn, olive & canola oils which I have addressed in this forum in detail and in my talk. I would recommend reading the paper on this issue. It says they found that when substituting these vegetable oils for saturated fat, there was a decrease in the numbers but no evidence on better CVD outcomes.That is exactly what I say in the fats talk and in this forum.  

It says olive has some more evidence from some MED studies and PREDIMED Trial, which I discuss in this forum and in my talk. They also say there are no studies comparing the MED to the Okinawan which uses virtually no nuts or oils and has great outcomes too. 
Most of what they are discussing is the impact of these oils on those on the SAD moving in our direction or on a current unhealthy MED diet. They are not discussing what happens when someone is on our diet and lifestyle and then adds the oil to them. These are all the same points I make in my writing/talks. Olive oil may be shown to decrease LDL or LDL oxidation when someone is not on a very healthy diet, but it is not going to decrease LDL or LDL oxidation even more when someone is strictly adhering to our recommendations.  

It's like the example I use on the nuts studies that show that adding nuts to a typical diet may lower TC 4.5% and LDL 6.5%. Yet, changing ones whole diet to the one we recommend without the use of nuts, lowered TC and LDL 25-30%, Will adding nuts now to that diet lower TC and LDL even more?
