Let’s talk about food.
Not just any food — the kind that keeps your brain sharp, your mood steady, and your energy up all day. Because what you eat? It matters. A lot.
Ever notice how skipping meals, loading up on sugar, or surviving on caffeine leaves you feeling exhausted, cranky, or totally unfocused? That’s because your brain needs the right fuel to function at its best. When you eat well, you think clearer, feel better, and have more energy to get through the day without counting down to your next nap.
Research backs this up. The British Dietetic Association (BDA) says the food you eat directly affects your mood, brainpower, and energy levels. So if you’re constantly running on coffee and convenience snacks, it’s no surprise when brain fog and afternoon slumps hit hard.
But here’s the good news: making smarter food choices doesn’t have to be complicated. A few simple swaps can keep you feeling more focused, productive, and just plain better.
So what should you eat when you need:
- A little mood boost to shake off a stressful morning
- Better focus so you can actually get things done
- Energy that lasts longer than your coffee buzz
- Calm when anxiety kicks in
The right foods can make a big difference in how you feel. Let’s dive into the best options for every mood.
What to Eat to Feel Your Best
Food isn’t just fuel — it affects how you feel! Some foods can boost your mood, help you relax, or give you energy. When you choose the right foods, you can feel better from the inside out.
Let’s explore the best foods to eat for every mood!
Feeling Down? Eat Mood-Boosting Foods
A long day at work can take a toll on your mood. But the right foods? They can help keep you calm, balanced, and maybe even a little happier.
Feeling blah? Try these:
🍌 Bananas – Packed with vitamin B6, bananas help your brain make serotonin, a feel-good chemical.
🐟 Salmon – Full of omega-3s, this fish helps fight stress and anxiety.
🍫 Dark chocolate – Just a small piece can trigger the release of endorphins, which make you feel happy.
🥜 Nuts & seeds – These are rich in magnesium, which can help reduce stress and boost your mood.
Try this: Snack on a banana with almond butter for a happy, stress-free boost!
When employees are stressed or anxious, their productivity suffers. The BDA notes that omega-3 fatty acids (found in salmon, walnuts, and flaxseeds) can help reduce depression and stress, while magnesium-rich foods (like nuts and seeds) help regulate stress hormones.
Wellness Idea: Offer healthy snack stations stocked with nuts, seeds, and fruit to encourage employees to reach for mood-boosting options instead of sugary treats.
Feeling Drained? Eat Energy-Boosting Foods
That mid-day slump is real, but you don’t need another cup of coffee to power through. Try these energizing foods instead!
🥑 Avocados – Packed with healthy fats and fiber, they keep your energy steady all day.
🍊 Oranges – A great source of vitamin C, oranges fight fatigue and keep you feeling refreshed.
🥦 Leafy greens – Spinach and kale are full of iron, which helps prevent tiredness.
🥜 Almonds – With protein and healthy fats, almonds help keep your energy levels stable.
Try this: Add avocado slices to your toast or throw some spinach into your smoothie for a natural energy boost!
Low energy means low productivity. And when employees are dragging, it shows. The BDA explains that foods with a low glycemic index (GI) — like whole grains, nuts, and fiber-packed veggies — help keep energy levels stable, so you’re not crashing an hour after lunch.
Wellness Idea: Stock the breakroom with energy-boosting snacks like trail mix, whole fruit, and protein-rich options like Greek yogurt.
Feeling Foggy? Eat Brain-Power Foods
Ever sit down to work and feel like your brain just... won’t? These foods can help keep you sharp and dialed in.
🫐 Blueberries – These tiny berries protect your brain and improve memory.
🥚 Eggs – Full of choline, eggs support brain function and focus.
🍵 Green tea – The caffeine and amino acids in green tea help you stay focused without the jitters.
🥜 Walnuts – Shaped like a little brain, walnuts are full of brain-boosting omega-3s!
Try this: Grab a handful of walnuts and blueberries for a brain-power snack!
Clear thinking leads to better decision-making, stronger problem-solving skills, and more productive workdays. The BDA highlights the importance of antioxidants, B vitamins, and omega-3s for brain health, noting that foods like blueberries, eggs, and walnuts help improve memory and concentration.
Wellness Idea: Add brain-boosting snacks to workplace wellness initiatives — think green tea, nuts, and fresh fruit at meetings instead of sugary pastries.
Feeling Anxious? Eat Comforting Foods
Work stress piling up? Feeling jittery? The right foods can help calm your mind and body.
🍞 Whole grains – Brown rice, quinoa, and whole-wheat bread keep blood sugar steady, preventing mood crashes.
🦃 Turkey – Packed with tryptophan, which helps your body make serotonin, the "feel-good" hormone.
🥜 Almonds – Rich in magnesium, these nuts support relaxation and stress relief.
🥛 Warm milk – A classic bedtime drink that can help you unwind.
Try this: Sip on warm milk with a sprinkle of cinnamon for a cozy, stress-soothing treat.
When employees feel anxious, their focus and productivity dip. Research shows that magnesium-rich foods (like almonds and leafy greens) can help regulate stress, while complex carbs (like whole grains) support steady energy and mood.
Wellness Idea: Stock the break room with stress-busting snacks like nuts, whole-grain crackers, and herbal teas to promote calm and focus.
