What does the last sentence mean? Our teacher, Mrs Walker, once said that if she finished the school year without strangling one of us it would be a miracle. At the end of Year Six all my class were still alive…at least I think they were still alive. Dylan Katano disappeared midway through the autumn term, but I heard he went back to Japan. Anyway, my point is that Mrs Walker was wrong. Not strangling one of 6W is not a miracle – even if we were a handful.

What does 'banging' here mean? This is a recipe from my friend Mary Shenouda, aka @PaleoChef on Instagram. I’d never tasted chicken liver before trying Mary’s dish, but it made me an instant convert. It is both delicious and a “banging” source of nutrients including choline, vitamin B12, folate, and vitamin A.

What does the first sentence mean? Cue the opening chords of “Eye of the Tiger.” (Prefer “The Final Countdown”? That works too.) You’re about to take an inventory of your kitchen and clear out the foods that are no longer serving you. Grab a garbage bag and get ready to load it up—this’ll be fun!

Is "Trader Joe' here the supermarket? Let us think back to a time before food delivery apps and diet gurus, when “Trader Joe”was the guy guarding the only salt lick in a hundred-mile radius and “biohacking” was something you did to a fresh kill with a sharpened stone. Government diet recommendations (or governments, for that matter) wouldn’t arrive on the scene for millennia, so you’d have to make do, as your ancestors did, with intuition and availability. As a forager, your diet would consist of a diverse array of land animals, fish, vegetables, and wild fruits. The chief calorie contributor would by and large be fat, followed by protein. 1 You might consume a limited amount of starch, in the form of fiber-rich tubers, nuts, and seeds, but concentrated sources of digestible carbohydrate were highly limited, if you had access to them at all. Q: Trador Joe IS the name of a supermarket. But in this context, as "a sharpened stone' is mentioned, I assume that "Trador Joe" might be a trador named Joe? Am I right? If so, why the trador is called Joe instead of other names?

What is 'nonstick coating' here? Remember those delicate, chemically reactive polyunsaturated fats from chapter 2? They are great for creating that nonstick coating on your skillet because they oxidize and bond to the iron so easily—the exact process that happens in your blood! It’s almost impossible to get a nonstick coating with olive oil or saturated fats because they are more chemically stable and not easily oxidized.

What does the last sentence mean? Last but not least, good-quality sleep is a precondition for optimal brain function and health. It gives you the ability to make dietary and lifestyle changes by making sure your hormones are working for you, not against you. And it purifies your brain and backs up your memories. Costco-size gains for dollar store effort, and yet our collective sleep debt is rising.

What does the last sentence mean? Still, many remain in the dark about this vast and rapidly growing body of research. A study performed by AARP found that while over 90 percent of Americans believe brain health to be very important, few know how to maintain or improve it. Even our own well- meaning physicians, to whom we turn when we’re scared and confused, are seemingly behind the times. The Journal of the American Medical Association itself reported that it takes seventeen years on average for scientific discoveries to be put into day- to- day clinical practice. 3 And so, we move through the motions as the old narrative continues— but it doesn’t have to be this way.

What does 'develop whiplash' mean here? Flash forward just a couple of decades to today and you could almost develop whiplash from the progress being made toward the understanding of our brains—both how we can protect them and how we can enhance them. Take the developments in the field of Alzheimer’s disease research. Alzheimer’s is a devastating neurodegenerative condition affecting more than five million people in the United States (with numbers expected to triple in the coming years); it is only recently that diet was thought to have any impact on the disease at all. In fact, though the disease was first described in 1906 by German physician Alois Alzheimer, 90 percent of what we know about the condition has been discovered in just the last fifteen years.
