What's a "Blue Zone"? It's Dan Buettner's name for areas in the world where people live a long time: Ikaria, Greece; Okinawa, Japan; Sardinia, Italy; Loma Linda, CA; and Nicoya Peninsula, Costa Rica. Dan and his team of experts determined that diet and certain activities make these people live longer. There are many similarities and some differences.
Similarities: They eat a lot of homegrown fruits and vegetables. "Organic" isn't some overpriced produce in the grocery stores, it's just the way food is grown and has been grown forever. This was once true in the United States of Big Ag (Chemicals R Us), too. Once. Anyway, they also tend to eat a lot of beans (legumes) and nuts/seeds. What they don't eat much of is meat. Maybe once a week or for celebrations. Eggs are used sparingly, too, as is dairy (the exception being goat and sheep milk/cheese, both more easily digested). Fish? In some cases, yes. In others, no. None of these groups have much use for sugar and salt. They eat whole foods. Bread? OK if whole grain, ixnay on white, sourdough OK, too.
Differences: Many consume lots of coffee, but the Seventh Day Adventists of Loma Linda, CA, shun it. Many consume one or two glasses of red wine with dinner, but again, the Adventists don't drink alcohol. As stated, some do more fish than others. Some (Costa Ricans) more corn and squash than others.
Habits: These people see food as a gift, a blessing. They sit down together -- no electronics ever -- they give thanks, they eat slowly, they enjoy each other's presence and company. They talk, by God! None of them go to gyms or go on diets, but all of them get plenty of exercise from everyday activities, which burn more calories in the long run: herding, gardening, fishing, walking places instead of driving places. Fasts also play a role, whether religiously-based or not. It might be weekly for a day or during special times of the calendar. Not eating some times is a healthy thing.
Many of these cultures eat bigger meals earlier, smaller later. Some eat two meals a day instead of three. In the Adventists' case, a lot of water is consumed (7 glasses a day). All groups get 7 or 8 hours of sleep a night. (Go ahead. Match it. I dare ya.)
So that's Part One of the book. Little magazine-article-like vignettes of the Zones. Part Two talks about trying to "make" blue zones, as is done in a small area of Finland, a town in Minnesota, three beach towns in California, and even a town in the Pig State, Iowa.
Part Three is about food rituals, menus, and everyday living. It's a blueprint for blue zones, a grass roots type playbook. Finally, at the end, we get 77 recipes, each inspired by the five original blue zone areas.
Yes, pretty legit stuff, though it's not exactly a gripping read and the science is off and on. For instance, Buettner still seems to believe the eggs/cholesterol myth, even though most modern studies have dispelled it. Eggs are not scary. He'll dis cow milk by saying it's "a relative newcomer, introduced about 8,000 to 10,000 years ago." Two pages later he celebrates beans, "the consummate superfood," by saying "Humans have eaten beans for at least 8,000 years" (the point being, A LONG TIME, even though the same point meant ONLY RECENTLY in the case of milk). All together now: Huh?
There are lots of little things like that. You'll see a YES for sweet potatoes but a NO for yams. Then, later in the book, in his list of Blue Zone foods, what does he list? You guessed it: Yams. Aye, Dios...
Also, there's more to this than diet and culture. Many of these places are enclaves outside of the super fast lifestyle we live. Little in the way of electronics, technology, cellphones, microwave whatevers zapping bodies 24/7. In short, life before science began simultaneously saving and killing us. Life that's simple enough to make people say, "Stress? What's that?"
But Dan just wants to talk about food and walking, so let's all agree that good food choices, good living habits, good fellowship (rugged individualism, an American staple = bad), and good walking places close enough to walk to will indeed advance our fragile little lives...
Great library loan book. Read, adopt with a friend. And family. Or church group near you.
