We’ve all heard the phrase, “You are what you eat,” but let’s be honest—most of us have rolled our eyes at it at least once. (Me, after a particularly indulgent pizza night: Sure, I’m mozzarella and carbs now. What of it?) But here’s the thing: it’s true.
Food doesn’t just fuel your body—it also has a direct line to your brain. The connection between what’s on your plate and how you feel is so strong, it’s like your gut and brain are texting each other all day long. Let’s dive into the science of how food affects your mood, energy, and overall vibe—and maybe have a laugh or two along the way.
Your Gut: The Overachiever You Didn’t Know You Had
If you think your gut’s job stops at digestion, think again. Your gut is basically a genius multitasker—digesting food, absorbing nutrients, and producing neurotransmitters (the chemical messengers that tell your brain how to feel).
In fact, about 90% of your body’s serotonin—a key player in mood regulation—is made in your gut. Yep, your “happy hormone” isn’t just a brain thing; it’s a gut thing. So, if your gut’s out of balance, your mood can take a nosedive faster than a sugar high wears off.
How to Support Your Gut:
Fiber-Rich Foods: Think veggies, fruits, and whole grains. Fiber feeds your gut bacteria, and a happy gut = a happier you.
Fermented Foods: Yogurt, sauerkraut, kimchi—these probiotic-packed goodies help maintain a healthy gut microbiome.
Ditch the Junk: Highly processed foods and excess sugar can throw your gut bacteria into chaos, leaving you feeling sluggish and moody.
Blood Sugar: The Frenemy You Need to Tame
Ever felt like you could conquer the world right after a sugary snack, only to crash and burn an hour later? That’s your blood sugar playing games with your energy and mood.
When you eat something sugary or refined, your blood sugar spikes, giving you that temporary boost. But what goes up must come down, and the crash can leave you feeling tired, irritable, and wondering why everyone suddenly seems so annoying.
How to Keep Your Blood Sugar Steady:
Pair Your Carbs: Always pair carbs with protein or healthy fats. For example, swap a plain slice of toast for one topped with avocado or nut butter.
Go Low-Glycemic: Choose foods like sweet potatoes, lentils, and quinoa, which release energy slowly and steadily.
Snack Smart: Instead of reaching for candy, try a handful of almonds or an apple with some cheese.
Micronutrients: The Unsung Heroes of Mood and Energy
Let’s talk about vitamins and minerals for a second. These little guys don’t get the spotlight they deserve, but they’re essential for keeping your brain and body running smoothly.
Key Micronutrients for Mood and Energy:
Magnesium: Known as “nature’s chill pill,” magnesium helps reduce stress and supports energy production. (Find it in spinach, almonds, and dark chocolate—yes, chocolate can be medicine!)
Omega-3 Fatty Acids: These healthy fats are like a hug for your brain, supporting mood and cognitive function. Salmon, walnuts, and flaxseeds are your best friends here.
B Vitamins: Vital for converting food into energy and supporting mental clarity. You’ll find these in whole grains, eggs, and leafy greens.
Caffeine: Friend or Foe?
Ah, caffeine—the fuel of modern civilization. It’s great for a morning energy boost, but too much can send you spiralling into jittery anxiety territory. And let’s not forget the dreaded afternoon crash when your coffee buzz wears off.
How to Use Caffeine Wisely:
Stick to 1–2 cups of coffee a day, and avoid it after 2 p.m. unless you enjoy staring at the ceiling at 3 a.m.
Opt for green tea if you want a gentler, sustained energy boost with a dose of antioxidants.
Try to go for organic, toxin free coffee as it often contains aflatoxins produced by certain moulds that grow on crop of coffee and peanuts and some people are extremally sensitive to it
The Big Picture: Food Is Fuel and Medicine
Here’s the bottom line: what you eat doesn’t just affect your waistline—it affects your brain, your mood, and how much energy you have to take on the world (or just make it through Monday).
If you’re constantly tired, cranky, or feeling off, take a look at your diet. Start by adding more whole, nutrient-dense foods to your plate and cutting back on the processed stuff. Small changes can lead to big shifts in how you feel.
And remember, it’s not about being perfect (because let’s face it, life without pizza isn’t living). It’s about making choices that support your body and mind so you can feel your best—most of the time.
