How can we make our gut healthier

Fibre is your friend

Fibre helps plays a huge role in creating a diverse biome of bacteria in your gut.

Some beneficial gut enhancing foods are sweet potatoes, spinach, beetroot, carrots and fennel. Most fruit and vegetables are a great sources of fibre and vitamins.

You could also try introducing more whole grains if you want to increase your fibre, for example, swap white bread, rice and oats for brown bread, porridge and rice.

Eat probiotic rich foods

Probiotics are thought to help restore the natural balance of bacteria in your gut. Some great sources of probiotics are mainly fermented foods like yogurt, kimchi, sauerkraut and kombucha.

Sleep

Make sure you’re getting a healthy amount of sleep. The average recommendation is 7-8 hours per night. Top tip, take lie ins on the weekend to make up for lost hours from busy weeks.

Less stress

Stress and the gut are directly correlated. The next time you are stressed stop and take a second to notice how your stomach is feeling. Butterflies, ulcers and an unsettled stomach are all examples of how your gut is impacted by stress.

Decrease alcohol

Excessive alcohol consumption is bad for your gut as it causes inflammation and wipes out a lot of the gut biome. Some symptoms of this could be heartburn, consistent discomfort, ulcers and bacterial infections.
