This post is just for fun, and light on science. So if you’re looking for something firm to hang your hat on, skip it. On the other hand, if you want to be bored by my personal thoughts, read on. 

Regular readers of this blog will have picked up on the fact that two of my biggest interests are 1) preventative medicine, and 2) history, and that these are two topics that I sometimes intermingle. For example, some time back I created a short post on ancient Roman military training and what it can teach us about exercise today. I also gave a lecture a few years ago in which I touched on ancient Roman lifestyle habits and how many of these weave nicely with what modern science has to teach us about good health. 

Today, I’d like to briefly return to this topic by discussing how the ancient Romans ate. But before doing so, I want to make two points:

1. The ancient Romans lived, on average, much shorter lives than we do. So it’s not that we should copy their world completely.
   
   But as the old saying goes, there are “lies, damned lies, and statistics,” and in point of fact a major reason that average life expectancy in Rome is estimated to have been about 30 years is that roughly half of all people in the Roman empire died in childhood. Of those who did survive to adulthood, many young women died in childbirth, and many young men died of traumatic injuries (being a Roman soldier, or building aqueducts by hand, turns out to have been dangerous work). As a result, an enormous percentage of the population died at a very young age, which brought the average life expectancy down considerably. But of those who didn’t die young, many went on to live a fairly full life, and in point of fact quite a few Romans lived into their 60s, 70s, and 80s. And while we have no way of knowing exactly what happened to these folks, there are many lines of evidence to suggest that they suffered less than we do from obesity, diabetes, cancer, heart disease, or dementia. The point being, there might be some things these ancient folks can teach us about how to age well, despite the fact that the majority of them never got the chance to.
   
2. Secondly, I am using Rome only because it is such a cultural touchstone of ours, but there’s nothing unique to Rome in what I am discussing. Substitute in any other pre-modern civilization – the Persians, the Ottomans, feudal Japan, or whomever you choose – and you could likely draw a lot of the same insights. 

With that out of the way, what did the Romans eat, exactly? We do have a fair amount of historical evidence on this front (several cookbooks from ancient Rome survive to this day, for example, and amongst the well preserved archeological remains at Pompei are included many restaurants). Therefore, historians are reasonably confident that a “typical” Roman (which is to say a citizen who was part of what we might now call the middle class, i.e. somebody who was neither extravagantly wealthy nor desperately poor) would have frequently consumed the following foods:

1. Whole grain sourdough bread
2. Porridges made of whole wheat or barley
3. Olive oil and olives
4. Red wine
5. Cheese
6. Fresh fruit
7. Vegetables
8. Beans
9. Eggs
10. Fish

If we think about this pattern, we’ll note a few things. Firstly, that it contains no processed or packaged foods (duh). Secondly, the diet is high in fiber and plant matter. Third, it is low in sugar (in fact the Romans didn’t have table sugar the way we do, though they did eat fresh fruit and honey to satisfy their sweet tooth). Fourth, it contains a fair amount of fermented foods (sourdough bread, cheese, wine), which we now know helps to nurture a diverse and healthy gut microbiome. Fifth, it is not per se low fat, but it is low in saturated fats and, of course, is completely devoid of the industrial and processed oils that are common in the modern western diet. 

In fact, if we examine the above diet, we’ll note that it is pretty consistent with the dietary pattern that modern nutritionists call the “mediterranean diet,” still followed in many parts of Greece, Italy, Spain, and other mediterranean countries, and which numerous studies have shown is a healthy eating pattern for reducing the risks for obesity, diabetes, and cardiovascular disease.  

Therefore, one way to look at healthy eating patterns is that they are something to be discovered by modern scientists. But another is that they are something to be re-discovered from our pre-modern ancestors who by a mixture of intuition and limited options (Burger King, sodas, and packaged chips just weren’t available to anybody living prior to a few decades ago) tended to follow, at least in some regards, a healthier eating pattern than we do.

One suggestion I often give my patients is to forget for a moment about fat, calories, protein, etc, and simply try never to eat a food that didn’t exist a century ago. If you follow no rule other than that, you will likely have a healthier diet than about 90% of modern Americans.

Please be aware that the office will be closed during the weeks of August 11th and August 18th for summer vacation. We will be re-opening on Monday August 25th.

If you are a current patient and have an urgent medical concern, please go to the nearest emergency room or urgent care center. You can reach out to me afterwards with a text message, voicemail, or email to update me on things so that I can follow up with you upon my return.

By contrast, if you are a current patient and need to reach me for a non-urgent issue such as getting a refill or discussing a minor medical problem, you can text or email me and I will get back to you, but there may be a delay of 24 hours or so as we will be traveling abroad.

Thank you for your understanding, and I hope you are having a nice summer.

A recently published study has gotten some press coverage suggesting that olive oil consumption can make you fat. For example, the (supposedly) respectable BBC ran a story under the headline “Too much of this ‘healthy fat’ could be adding to your waistline, study finds.”

This is yet another example of what I have termed the “Academic-Media Complex,” in which bad studies are given hyped up reviews by the media, leading to more funding for research universities and more sales/clicks for news organizations, but poor information for the public. 

If you read the original study (which you can by clicking here) the results are – shocking, I know – hardly what they are hyped to be. 

What in fact did the study show?
