Like so many other works I have read in the last couple of years, this book challenged my thinking and debunked a whole host of "truths" to which I had subscribed for the last three decades.
Here are some of my biggest takeaways from this book (though not an exhaustive list, by any means):
- Modern grains are silently destroying our brains.
- Our food actually regulates our genetic expression.
- Alzheimers and dementia (as well as other diseases of the brain) are predominantly dietary in genesis.
- High carbohydrate and high gluten diets set our brains "on fire" through inflammation, which causes oxidation (i.e. "rusting").
- Gluten is the equivalent of tobacco for our generation.
- Fat - not carbohydrates - is the preferred and fundamental fuel for the human brain (and always has been).
- Fat is good. Cholesterol is good. Statins are bad. Sugars are bad. Carbohydrates are bad. Gluten is bad. For the brain.
- The brain thrives and grows as an effect of physical exercise.
- The fatter the human, the smaller the brain.
- A tremendous amount of neural activity occurs in our intestines (our "second brain").
- Our brains do, in fact, behave like muscles - they grow, they strengthen, they become more nimble, they have better endurance, when challenged.
There's a ton more I learned from this book, but I'll stop here, in the interest of being relatively succinct. If you read it, get ready to have many assumptions and myths about health/nutrition challenged and debunked.
A very good read.
