Time of Eating & Health!

13 Jun

I made my first science communication video! It took me only ~ 15 hours, no big deal 🙂

It won’t be as time consuming from now on..but there is a lot of work involved nevertheless: writing a good concise script, sketching all the images that could go along with it, setting up the recording (can be so tricky!), recording yourself draw (and redraw.. and redraw) every frame.. Then editing all those videos, recording the audio (and re-recording..and re-recording again), and finally matching video to audio (as well as finding some free background tunes to go along!). Check it out: 


I chose this topic because i’ve been craving to cover it for some time now. Since my dissertation work focused on lay models of healthy eating across cultures (so: people’s beliefs about what it means to eat well), I did not address the scientific accuracy of any perceptions. But oh I wanted to! And that is because one of the most fascinating findings from my interviews was that eastern European (EE) participants considered “how you eat” (i call these “eating styles”) to be more important for health than American respondents.

Eastern Europeans (EE) judged statements about EATING STYLES (such as time of eating) as more important for health…

Specifically, EE participants rated the statement “it is important to avoid eating late in the day” significantly higher than Americans (and this was true from my past survey-based studies!).

This is what the image below shows, but let me explain the method behind it: I conducted >70 interviews in the U.S., Romania, and Ukraine where I asked people to look at 42 different statements about “healthy eating”. Among other activities, they had to indicate how much they personally agreed with each statement (from “4” agree completely to “-4” disagree completely; I used Q Methodology for this, by the way ).

So, between Americans and eastern Europeans, 1 statement about eating styles (or “context” as I referred to it in this chart) that was more important for the latter: not eating late. 

So, out of ALL 42 cards, only “avoid eating late in the day” got a statistically significantly higher agreement score from eastern Europeans. AND when prompted to explain their views, my respondents gave an explanation that was amazingly close to the actual science of circadian rhythms!!

Why did EE folks seem to know about circadian rhythms way more than Americans?

I didn’t analyze why EE folks seem to know about circadian rhythms way more than Americans, but this knowledge is something they knew from childhood.. It was part of general recommendations and “common sense” while growing up in the USSR. It fact, importance of eating styles is prominent in traditional beliefs about health (like in Japan and China).. perhaps all the focus on nutrients that’s possible with modern science is taking our attention away from this old wisdom?

Now that nutrition science is paying increasingly more attention to eating styles as well (CHRONO-NUTRITION!), I assume American folks will begin incorporating beliefs about importance of food timing also!
