I know many of you are much earlier than I am, to the realization that meat is not bad, and low-fat is not good. And to be fair, I've been pretty skeptical of those claims for a while. But the book "The Big Fat Surprise: Why Butter, Meat, and Cheese belong in a healthy diet" by Nina Teicholtz has been a complete mind blower. I highly recommend it.
I had no idea that the evidence behind so many of these hypotheses (saturated fat is bad for you, a low-fat is good for you, a vegan or near-vegan diet is the best, etc) have almost no good evidence. And it's not just that. In many cases, the studies designed to prove these hypotheses sometimes show the opposite, with the low-fat diet leading to overall higher mortality.
This is especially meaningful because people who follow low-fat health guidelines tend to follow other, more sensible health guidelines. For instance, people who are vegetarians are often non-smokers, and also exercise - both of which are associated with better health.
And despite this, these guidelines have been promoted and propagandized to the point that expressing skepticism about them is looked on as similar to devil-worship. For instance, in schools in the US, you cannot offer children whole-fat milk. It has to be either skim milk, or chocolate milk (skim milk with chocolate syrup).
The pushing of the pro-vegan agenda is visible everywhere. On YouTube, despite not ever clicking on any of them, I'm constantly seeing videos with titles like "These lentil patties are better than meat!" There must be some algorithm pushing them down our throats.
It's been a winding road for me, but the covid insanity has gone a long way in showing me just how corrupt and misguided "science" can be. I'm now starting to bulk purchase all the good stuff - meat, butter, etc, and of course am cooking up more meat-oriented recipes, and de-emphasizing salads and veggies.
FYI - I was introduced to Nina Teicholtz through an interview on the Bitcoin Standard podcast by Saifedean Ammous (https://saifedean.com/podcast/71-fiat-nutrition-with-nina-teicholz). That interview, also with some information on why she was inspired to do the research to write the book, intrigued me and made me dig up the book. But if you're looking to save time, I highly recommend listening to the interview, it was outstanding.
