The Mediterranean Diet: What Is It Good For?
More to the point: what isn’t it good for?
- It’s been found to reduce all-cause mortality, which is about the best thing one can say of any diet.
- It’s especially good for heart health and against cancer.
- It’s particularly recommended for the prevention or management of diabetes.
- It’s also been found, societally, to reduce general healthcare costs—basically, people get sick less and so have fewer healthcare costs.
What brought it to the attention of the world’s scientific community?
Back in the 1950s, physiologist Ancel Keys wondered why poor people in Italian villages were healthier than wealthy New Yorkers. Upon undertaking studies, he narrowed it down to the Mediterranean diet—something he’d then take on as a public health cause for the rest of his career.
Keys himself lived to the ripe old age of 100, by the way.
When we say “Mediterranean Diet”, what image comes to mind?
We’re willing to bet that tomatoes feature (great source of lycopene, by the way), but what else?
- Salads, perhaps? Vegetables, olives? Olive oil, yea or nay?
- Bread? Pasta? Prosciutto, salami? Cheese?
- Pizza but only if it’s Romana style, not Chicago?
- Sautéed liver, with some fava beans and a nice Chianti?
In reality, the diet is based on what was historically eaten specifically by Italian peasants. If the word “peasants” conjures an image of medieval paupers in smocks and cowls, and that’s not necessarily wrong, further back historically… but the relevant part here is that they were people who lived and worked in the countryside.
They didn’t have money for meat, which was expensive, nor the industrial setting for refined grain products to be affordable. They didn’t have big monocrops either, which meant no canola oil, for example… Olives produce much more easily extractable oil per plant, so olive oil was easier to get. Nor, of course, did they have the money (or infrastructure) for much in the way of imports.
So what foods are part of “the” Mediterranean Diet?
- Fruits. These would be fruits grown locally, but no need to sweat that, dietwise. It’s hard to go wrong with fruit.
- Tomatoes yes. So many tomatoes. (Knowledge is knowing tomato is a fruit. Wisdom is not putting it in a fruit salad)
- Non-starchy vegetables (e.g. eggplant yes, potatoes no)
- Greens (spinach, kale, lettuce, all those sorts of things)
- Beans and other legumes (whatever was grown nearby)
- Whole grain products in moderation (wholegrain bread, wholewheat pasta)
- Olives and olive oil. Special category, single largest source of fat in the Mediterranean diet, but don’t overdo it.
- Dairy products in moderation (usually hard cheeses, as these keep well)
- Fish, in moderation. Typically grilled, baked, steamed even. Not fried.
- Other meats as a rarer luxury in considerable moderation. There’s more than one reason prosciutto is so thinly sliced!
