POOR gut health is linked to autoimmune diseases, mental health disorders and even cancer.
It’s also said to increase your risk of , as well as , , and skin conditions like .

Almost half of us have indicating our â from to â but what can we do about it?
Much like with , there is no quick fix â no cleanse or detox is going to bring about instant radical changes.
But you can make a real difference in as little as seven days.
OK, a week of won’t prevent serious diseases, but you should feel considerably better.
After that, it’s about adopting sustainable lifestyle habits to support you long term.
Caff Rabess, a registered dietitian and clinical lead for an NHS nutrition and dietetic service, who works with Yakult, tells Sun Health: “Imagine having a friend who always looks out for you â helps you stay well, supports your mood and understands exactly how you tick.
“Now, what if that friend already exists within you?
“Your gut, along with its nervous system (often called the ‘second brain’), plays a crucial role in your overall wellbeing.
“It communicates with your brain, influences your immune system and even affects your mood.
“Just like a good friend, your gut thrives on care, attention and love.
“When you nourish it, treat it well and listen to it, it works in harmony with the rest of your body.
“But neglect it and you may feel the effects â low energy, digestive discomfort and even shifts in your mood.”;
The gut refers to the gastrointestinal tract â the long tube extending from the mouth to the anus â and encompasses the stomach and intestines.
It’s primarily responsible for digesting , absorbing nutrients, and eliminating waste.
The gut microbiome is the ecosystem of more than 100 trillion microorganisms â including bacteria, fungi and viruses â that live in your intestines.
But we often don’t give them much thought. Research by YouGov shows people are more likely to think about their weight, , and ahead of their digestion.
That’s despite almost half (43 per cent) of the UK population experiencing some form of â whether that’s , or extra gas.
And those of us that do might reach for instead of fresh produce.
Well that’s unnecessary, according to Farzanah Nasser, gut health nutritionist at Biotiful.
She says: “In a world obsessed with supplements and quick fixes, we’ve lost sight of the simplest, most effective way to support, or ‘reset’, our gut â through natural foods that have been enjoyed for centuries.
“It’s time to go back to basics. Supporting your gut health does not need to be complicated.
“Including more fermented foods for seven to 14 days, alongside 30 different plants, could significantly improve the abundance of healthy bacteria in your gut.
“Plant foods include everything from fruits, vegetables, nuts, seeds, herbs, legumes, grains, teas and spices â so there is a lot to choose from.
“Fibre is also crucial â we should all be aiming for 30g a day â as it promotes a healthy microbiome, and helps to keep us fuller for longer and support balanced blood sugar.”;
Good gut health is linked to better sleep, improved fitness, better memory and focus, and even healthier skin

She adds: “Be sure to go outdoors and get some fresh air.
“The gut and brain are in constant communication, meaning a happy gut can help support a happy mind, and vice versa.
“Sunlight can also influence gut health and help improve your mood and energy levels.
“But also prioritise sleep, which is important to help maintain gut health, plus a lack of sleep makes us crave more sugar and feel too tired to cook.
“You want to aim for seven to nine hours of sleep each night to keep your gut â and your mind â satisfied.”;


Do all this, and you’ll be happier and healthier.
“Maintaining a healthy gut is not just about digestion â it has a positive impact on almost every system in the body,”; Farzanah says.
“The benefits vary from person to person, but they range from stronger immunity and weight management to increased energy levels.
“You might also be less bloated, have lower stress levels and have boosted your mood.
“And it doesn’t stop there â good gut health is linked to better sleep, improved fitness, better memory and focus, and even healthier skin!”;
