Walnuts & Satiety: A Tale of Two Perspectives

Here is a study on walnuts and satiety. You can read the full text here...

Here is one way it is being interpreted and presented...

"An elegant study is presented testing the appetite-suppressing effects of walnuts."

Here is another way the exact same study is being interpreted and presented...

"Here's a study on walnuts which some people are touting as "an elegant study presenting testing of the appetite-suppressing effects of walnuts." Really? You can read the methods yourself, but bottom line for this walnut-industry funded study: they took 15 people and for 4 days gave them a breakfast shake. Either they got a fruit shake made with walnuts, or a fruit shake made with safflower oil. Guess what, the people who had the walnut shake said they felt a little "fuller" just before lunch. They didn't lose any weight, because the researchers made it so that everyone in the study ate identical amount of calories. It was a 4 day study, done twice, with just 15 people, and the people whose breakfast shake was made with walnuts rather than oil, reported feeling a little fuller just before sitting down for lunch.

The walnut industry had hoped to show that walnut consumption helped protect against diabetes, but that didn't happen.

So this is a total BS study that simply shows that walnuts are more satiating than safflower oil. That's all it shows. Drink ground up walnuts rather than safflower oil, if you like liquid breakfasts, and you may feel satisfied a little bot longer. Whoop de do. This doesn't apply to anyone I know.

But the fact that this study is being touted as some great breakthrough study about walnuts...shows some people have a penchant for passing off silly "science" as "important" to their audience... If the dairy industry had put out a phony study like this, vegans would all be up in arms debunking it as the industry-funded trash science it is. But since the walnut industry did it, some vegans get all excited and call it "elegant." Bottom line: beware where you get your info. :)"


This is why the points I make in the following discussions, and the concepts described by Dr Campbell in his new book, Whole, are so vitally important.
