Wellness Wisdom Episode 5: Dealing with Stress and Anxiety
Jonathan: Hi, I'm Jonathan Tessier, and we're here back with one of our health tip videos with our nutritionist, Rebecca. How are you doing, Rebecca?
Rebecca: I'm good today. How are you, Jonathan?
Jonathan: I'm doing pretty good. Have you been stressed or anything like that lately?
Rebecca: Well, I mean, the elections, the power outage, all of that. I try to keep it under control for the most part, but I think we were all feeling it the past few weeks a little bit, yeah. It's hard to avoid sometimes with everything going on in the world.
Jonathan: Yeah. That's why we're going to do a little bit of a video right now about dealing with stress and anxiety. So let's just dive right into it. How can the food we eat contribute to our stress and anxiety? Are there foods we should avoid? And are there foods we should prioritize?
Rebecca: Yeah, that's a really good question. Three things come up when I think about this. One is blood sugar, which I know we've talked about in a previous video, but we'll talk a little bit about that today. The other is the microbiome, which we'll get into a little further later, but that's an important factor. And the third thing is nutrient deficiencies.
Blood sugar can have a really huge impact on stress and anxiety if we're not fueling ourselves properly so that we can sustain ourselves for a few hours after a meal. Our blood sugar can rise and then fall, and that can contribute to a lot of anxiety.
So one factor is making sure that your meals include fat, fiber, and protein. Generally, the carbs will sneak themselves in there. But if you can make sure that all those things are included and you're getting a sufficient amount of especially protein in your meals, you'll be satiated longer and your blood sugar will be more stable.
It's often that hypoglycemic response that can lead to anxiety. I know we can all relate to being a little bit “hangry.” That’s what that is.
The other thing is nutrient deficiencies. It’s really important that we’re eating a variety of different foods — different types and colors of foods — so we’re getting a range of nutrients in our diet, because different deficiencies can add to stress.
Then the last thing is that gut-brain connection. If we're eating a lot of high-sugar foods and really processed foods, that can wreak havoc on our gut — our second brain. There’s a very strong connection between our gut and our brain. When that’s off balance — too much of one bacteria and not enough of another — that can lead to stress and anxiety as well.
So kind of those three things:
- Eat diverse foods.
- Keep your blood sugar stable with fat, fiber, and protein.
- Avoid too many non–gut-healthy foods.
Gut-healthy foods include fermented foods, diverse fiber (both soluble and insoluble), and a variety of colorful foods.
Jonathan: Can timing of meals impact how we cope with stress throughout the day?
Rebecca: Absolutely. That goes back to the blood sugar picture. Eating meals in a way that avoids your blood sugar dropping too low helps prevent that hangry feeling.
The other thing is your circadian rhythm. Your body loves to operate on rhythms, and that’s how we tell our bodies we’re safe — by timing our meals consistently.
For example, every morning when I wake up, I make sure I have a good healthy breakfast, then eat again at lunch, maybe a snack in between, and then dinner at a consistent time. That’s a great way to tell your body you’re safe and to anchor your day, especially during stressful times.
Jonathan: What role does gut health play in influencing stress and anxiety?
Rebecca: Gut health is a really important factor to consider when stress and anxiety are something you’re trying to manage. For example, most serotonin is actually made in our gut. We often think of neurotransmitters as coming from the brain, but many are produced in the gut.
So gut health is key. You’ve probably heard about probiotics, prebiotics, and postbiotics — all of that helps keep the gut in balance. We don’t want too much or too little of any type of bacteria. I’m trying to move away from calling them “good” or “bad” bacteria — it’s more like a fine symphony happening in your gut.
Jonathan: Beyond diet, what are some lifestyle changes that people can make to help with their stress and anxiety?
Rebecca: There are a million different things you could implement to help manage stress and anxiety. The first question I would ask myself is: am I taking time for myself in a day? We’re all so busy, but that’s really the first step — slowing down enough to take time for yourself. I think of kind of that... avatar of a busy mom that's busy taking care of her family. Maybe she has elderly parents she's taking care of and then her kids, and she gets lost in the mix.
That would be the first thing I would ask—is do I even, am I taking any time for myself in a day and then carving out even if it's just 15 minutes to do something?
Maybe that’s reading a book, sitting down in a quiet room with a tea, or going for a walk. It could be as simple as that—just carving out that time to get your body out of that fight-or-flight state and into that rest-and-digest state.
But yeah, there are lots of different avenues that you can take. I think it's whatever kind of piques your interest—whether it's movement and you need to get your one hour at the gym every four or five days a week, or whatever it is that's going to be helpful.
Maybe it's just a meditation practice in the morning, as simple as five minutes in the morning or whenever you can fit it in during the day. It can be that simple. Maybe it’s breathwork that you’re participating in.
So many different avenues that you can take. But the first thing I would think is: okay, have I taken 15 minutes to get in that parasympathetic or rest-and-digest state today? That can look so many different ways for so many different people.
Jonathan: Absolutely. Those are all great suggestions. I know when some people are stressed, they consume caffeine. How does that affect anxiety and stress, and are there good substitutes for it?
Rebecca: Yeah, that’s a great question. Everyone responds to caffeine differently. I’m sure you’ve heard of people who can, at midnight, have a cup of coffee and go to bed. I’m not in that camp—I should stop drinking coffee around noon or I find it impacts my sleep.
It’s said to often come down to liver function—different pathways in your liver and how they respond. Everyone responds to caffeine a little bit differently, and you probably know where you land on that spectrum. So just mindfully consuming caffeine is important.
For those of us who know it’s not great after noon but still like a cup, there are so many alternatives. One example is matcha. Matcha has caffeine, but it also has L-theanine, so instead of getting that big, jittery spike, it gives a more focused, balanced energy.
Another option is Inka coffee substitute—often made with chicory, barley, and dandelion. We’ve also got lots of Teeccino options, which are herbal blends that taste like coffee.
So there are many options on the shelf for caffeine substitutes. Caffeine can really impact anxiety—especially if we’re drinking it without food or not staying hydrated. It’s worth asking: is it another coffee I need, or do I need water, food, or just five minutes to pause and breathe?
Jonathan: Exactly. There are a lot of substitutes here that taste like coffee but are better for you and your anxiety.
What you mentioned about cortisol earlier—could we talk about that? What role does cortisol play in stress and anxiety?
Rebecca: Yes, cortisol is one of our main stress hormones. It’s often villainized, but it’s actually really important. We want a bit of cortisol when we’ve got a deadline or need a little boost—it helps us get things done. But chronically high cortisol can be problematic. When it stays high long-term, you’re not responding to things as well. Think of when someone cuts you off in traffic—your heart rate and blood pressure rise, you get that rush. That’s cortisol. Short-term, it’s useful. Long-term, it can suppress calming hormones like dopamine and serotonin, leading to anxiety and poor sleep—which in turn worsens anxiety.
So managing cortisol is key. Practices like breathwork, yoga, and regular movement all help regulate that response.
Jonathan: Are there any supplements that can help with stress and anxiety?
Rebecca: Yes, absolutely—many options. A few nutrients get depleted quickly under chronic stress, like magnesium, vitamin C, and B vitamins. Magnesium, for instance, is great to take before bed to help promote deeper sleep and lower cortisol.
Another great product is “Strest” by St. Francis, a blend of adaptogenic herbs that help your body adapt to stress—neither overreacting nor underreacting. It includes rhodiola, ashwagandha, and calming herbs like oat straw.
Adaptogens can be taken individually too, like ashwagandha from Living Alchemy.
For quick relief, I like chewable L-theanine from Natural Factors. It works within about 15 minutes to promote calm and focus.
Another option is Rescue Remedy—a homeopathic blend available as drops or candies—for quick, in-the-moment calm. Adaptogens work best over time, while things like L-theanine or Rescue Remedy can help right away.
Those are just a few of the many options we carry at Jo Anne’s Place to help customers manage stress and find what works best for them.
Jonathan: Yeah, so honestly, we have so many products that we have so many supplements for you to try out here on Joanne's place that will help with your stress and anxiety. And we have tons of people. Here who will give you expert advice, like our nutritionist Rebecca, who will guide you on your journey through figuring all this out. So that'll do it for today, but we'll be back with another health tip video very soon. Have a good one.
