Gut Health and Depression: What the New Science Says
Did you know your gut health can affect your mood?
A Harvard Health study confirms it — the gut-brain connection is real. When your gut is out of balance, it may increase feelings of anxiety or even depression.
Your gut is home to over 40 trillion bacteria, most of which live in your digestive tract. These microbes are part of your gut microbiome, and they play a big role in your overall health — not just digestion.
Recent studies link gut health with mental health, immune strength, skin conditions, autoimmune diseases, and even cancer.

What Is the Gut-Brain Connection?
Your gut and brain constantly talk to each other through nerves, hormones and the immune system.
This two-way communication is called the gut-brain axis. When your gut is unhealthy, it can send distress signals to your brain and vice versa.
8 Signs Your Gut May Be Out of Balance
A healthy gut has a balance of good and bad bacteria.
If your gut health is off, you may experience:
- Bloating or stomach pain
- Weight gain or weight loss
- Skin rashes or acne
- Food cravings (especially sugar)
- Sleep issues or fatigue
- Migraines
- Allergies
- Autoimmune flare-ups
If these sound familiar, your gut may be trying to get your attention.
6 Easy Ways to Support Your Gut Health
1. Drink More Water
Hydration supports healthy digestion. Aim for at least 1.5L daily.
2. Eat Gut-Friendly Foods
Your gut bacteria feed on what you eat.
Support them with:
- Fermented foods: kimchi, yoghurt, kefir, tempeh, miso, kombucha, and Black Garlic!
- Fibre-rich foods: legumes, oats, beans, whole grains, and veggies
- Prebiotics: garlic, onion, banana, berries, tomato
Limit sugar and processed foods, and avoid known food triggers where possible.
