Today I’m sharing studies on how diet affects depression, specifically looking at fast food, pastries / baked goods, and processed foods. Only some of these categories actually seem to contribute to depression, whereas others don’t! I also talk about findings showing exercise plays a big role in how these foods contribute to depression.

Today I’m sharing studies on how diet affects your mood, through tryptophan and serotonin. Specifically, I’m talking about how eating a high protein vs high carb diet affects your serotonin levels, and therefore mood, depression, and anxiety! (This is a follow up to my last video on dietary tryptophan & mood)
Today I’m sharing something a little closer to my personal research interests (given that I’m getting my PhD in psychology/neuroscience): how your diet can affect your mood! In the video I quickly cover tryptophan, the amino acid that has antidepressant-like effects, and go over a study directly looking at how people’s symptoms of depression, anxiety, and overall mood are affected by being put on a high vs low tryptophan diet.
And the list of high-tryptophan foods from the study is below!
Hey friends! Today I have advice & a super cool study for you on how to stop negative emotions from making you overeat or binge eat. This study also has useful advice for how to feel fewer negative emotions generally!
For the highlights, check out the video:
And now, the details & how to use the strategy into your own life:
Emotions are a MAJOR cause of overeating–in fact many scientists think it’s THE cause of binge eating disorder (BED).
So in this study, they tested whether a simple psychological trick could prevent people from overeating when feeling sad.
They had two groups: a group of 39 overweight women with BED, and a control group of 42 overweight women (weight-matched) without binge eating. Their average BMI in both groups was 34. The BED group was bingeing 4x a week on average, for at least the last 6 months.
They had the participants watch a really sad movie, had them use one of two emotional regulation strategies, then looked at how much they ate afterwards from bowls of biscuits and chocolate M&Ms.
They split the BED and control groups into two strategy groups: suppression and reappraisal. For the people in the suppression group, they told them to suppress their emotions:
Try to hide your feelings. Try to behave in a way that someone watching you would think that you don’t feel anything at all. Try to hold a neutral expression so no one can read your feelings from your face. You can feel whatever you feel, but try your best not to show it.
For the people in the reappraisal group, they told them to try to change how they felt about the movie by focusing on different aspects:
Try to distance yourself from the movie and see it objectively. Whenever you sense a change in your feelings while watching, try to internally step back. For example, think of how the photographer and actors succeeded in presenting the scene.”
(Instructions in studies tend to be REALLY repetitive to make sure participants get it, so I paraphrased 😉 )
Suppression means doing nothing to actually help you stop feeling the feelings, but just hiding or ignoring them. Reappraisal means trying to be less involved in the negative emotion–focusing on other aspects of the situation, distancing yourself from the situation, or looking at it as sort of a scientist. Reappraisal is actually a big reason why some people cope better with negative emotions than others: they naturally do more reappraising. (More specific advice on this below!)
So the participants watched a movie scene about the loss of a loved one, and other studies have shown that the movie scene makes people really sad. After the movie, both groups of participants rated themselves as feeling more sad than before the movie. But, the group that had done reappraisal during the movie felt less sad.
Then, they gave each participant a bowl of biscuits and a bowl of M&Ms, and told them they were doing a taste test to see how the movie affected their ratings of how good the food tasted. They had 15 minutes to eat & fill out questionnaires about how good the food tasted. They had all been told to eat a regular meal 2 hours earlier, so they weren’t coming in hungry.
Participants in the suppression group ate 40% morethan the reappraisal group. And this applied to both people who binge ate, and those who didn’t. Over 15 minutes this amounted to 30 extra calories, but imagine…
If you would usually have eaten 1100 calories in a binge, this strategy could make that an 800 calorie binge instead.
And, more importantly, learning reappraisal can help you deal with negative emotions better over time (tons of other research has shown this) and break the bingeing cycle completely.
Interestingly, the group with BED tended to use suppression in daily life much more than the control group, and used reappraisal a lot less. So that may explain how binge eating arises in the first place.
So, how can YOU start reappraising?
Reappraisal means changing the way you think about a situation. Most of the time, we only feel negative emotions because we decide that a situation is bad: for example, for one person starting a new job might be exciting; for another, it might be terrifying. Same situation, different perspectives.
So how do you reappraise a situation?
Let’s say your significant other breaks up with you. A natural reaction may be to feel worthless, self-loathing, etc. A reappraisal strategy here would be to focus on how maybe the situation isn’t the worst thing ever. Focus on the ways in which it might be a good thing: maybe he wasn’t a great match for you anyway, maybe he prevented you from seeing friends or pursuing your hobbies, and there’s definitely someone better out there for you.
Suppression, on the other hand, would be to “put on your brave face” and make it seem like the breakup didn’t affect you.
With reappraisal, challenges become opportunities for growth.
Try asking yourself questions like these:
What did you learn from the situation?
Can you find something positive that might come out of it?
Are you grateful for any part of it?
Are you better off in any way than when you started?
Could it have helped you grow or develop as a person?
So, next time you’re feeling overwhelmed with emotions, try reappraisal. It may help you feel better instead of leading to a binge.
