(And What to Do About It)

Let’s be honest about what we’re actually eating
If you’re over 40, you’ve probably noticed that the foods that used to satisfy you just don’t hit the same way anymore. Life gets busy, we grab what’s convenient, and somewhere along the way, our energy crashes and our mood follows.
Here’s the thing: it might not be stress, hormones, or lack of willpower. It could be what’s actually in your food.
What is an “Ultra-Processed Food” (and why does it matter)?
Ultra-processed foods aren’t just the obvious suspects like chips and candy. They’re the sneaky ones hiding in plain sight—that “healthy” granola bar, the flavored yogurt you thought was a good choice, even some plant-based meat alternatives.
The difference isn’t about being “processed” (hello, cheese and bread have been processed for centuries). It’s about foods that have been completely deconstructed and rebuilt with ingredients you wouldn’t find in your grandmother’s kitchen. Think emulsifiers, artificial colors, flavor enhancers—the stuff that makes food last forever on shelves and taste irresistible.
Dr. Carlos Monteiro, who created the system we use to classify these foods, calls them “industrial formulations.” Basically, if the ingredient list reads like a chemistry experiment, you’re probably looking at an ultra-processed food.
The mood connection is real (and it’s not just in your head)
I know, I know—another study telling us our favorite foods are bad. But hear me out.
A massive study published in 2024 looked at data from millions of people across different countries and found the same pattern everywhere: people who ate more ultra-processed foods were more likely to struggle with depression, anxiety, and other mood issues.
One study followed over 31,000 American women in their 40s and 50s for years. Those who ate the most ultra-processed foods—especially the artificially sweetened ones—had higher rates of depression. But here’s the encouraging part: when women cut back on these foods, their depression risk actually dropped.
Now, before you panic about that diet soda addiction, remember this doesn’t prove that ultra-processed foods cause depression. But the pattern is consistent enough that it’s worth paying attention to.
Why your favorite snacks might be working against you

There are three ways ultra-processed foods might be messing with your mood, and honestly, none of them are your fault:
Your brain gets hijacked by the food itself
Scientists at the National Institutes of Health did something brilliant—they fed people two different diets for two weeks each. Both diets had the same calories, protein, fat, carbs, sugar, and fiber. The only difference? One was made of ultra-processed foods, the other wasn’t.
On the ultra-processed diet, people ate about 500 extra calories a day without even trying. They gained weight. Same people, same willpower—different food.
The researchers concluded that ultra-processed foods literally “cause excess calorie intake.” It’s not about self-control; it’s about food that’s designed to override your natural satiety signals.
Your gut bacteria revolt
This one sounds weird, but stick with me. Your gut is home to trillions of bacteria that help digest food and communicate with your brain. When researchers fed people common food additives like carboxymethylcellulose (found in many “low-fat” and “sugar-free” products), the good bacteria decreased and inflammation markers went up.
Less good bacteria means fewer of the compounds that help regulate mood and brain function. It’s like your gut-brain connection gets static interference.
Your hunger signals get confused
When your gut bacteria are unhappy, they produce fewer short-chain fatty acids—compounds that help regulate everything from immune function to neurotransmitter balance. When these are low, your body’s internal communication system gets wonky, affecting everything from appetite to mood.
What the experts are saying (in plain English)
The scientists studying this stuff are being pretty clear:
- Dr. Kevin Hall from the NIH: Ultra-processed foods make people overeat and gain weight even when calories are matched. The form of the food matters, not just what’s in it.
- The BMJ review authors: Greater exposure to ultra-processed foods is linked to worse health outcomes, including mental health problems. This isn’t just about individual choices anymore—it’s a public health issue.
- The depression study researchers: Cutting back on ultra-processed foods, especially artificially sweetened ones, was associated with lower depression risk in midlife women.
A realistic plan that won’t make you miserable
Look, I’m not going to tell you to throw out everything in your pantry and start fermenting your own vegetables (unless that’s your thing). Life is complicated enough. Instead, let’s make some swaps that actually stick:
Start with your biggest hits
Pick the two ultra-processed foods you eat most often and find simple swaps:
- Flavored yogurt → Plain Greek yogurt with berries (add honey if you need it)
- Granola bars → A handful of nuts with a few squares of dark chocolate
- Diet soda → Sparkling water with a splash of real fruit juice
Feed your good gut bacteria
Aim for what I call the “fiber trio” most days: leafy greens, beans or lentils, and berries. These feed the bacteria that make those mood-regulating compounds your brain needs.
Play detective with labels
Spend 30 seconds checking ingredient lists. If you see things like carboxymethylcellulose, polysorbate-80, or a bunch of numbers and letters, that’s your cue that this is a “sometimes” food, not an “every day” food.
Build better dinners without the fuss
Here’s a template that works: good fat (olive oil) + aromatics (onion, garlic) + lots of vegetables + protein (fish, beans, tofu) + fresh herbs. Finish with fruit and plain yogurt for dessert. It sounds fancy but takes 20 minutes.
Track what matters to you
For a week, just notice: How’s your energy in the afternoon? How strong are your evening cravings? How do you feel when you wake up? If small changes help these things, you’re onto something.

The bottom line: progress, not perfection
You don’t need to become a food purist. The goal isn’t to never eat anything that comes in a package again. It’s about shifting the balance—eating fewer foods that mess with your hunger signals and more foods that work with your body instead of against it.
Many people find that when they reduce ultra-processed foods, the constant “food noise” in their head quiets down. Cravings become less intense. Energy becomes more stable. Mood follows suit.
The research is still evolving, but your experience is what matters. If eating closer to whole foods makes you feel better, that’s all the evidence you need.
A gentle reminder
If you’re dealing with depression, anxiety, or taking medications for mental health, definitely talk to your healthcare provider before making big dietary changes. Food can be powerful medicine, but it works best as part of a complete approach to your wellbeing.
