Discover Good Gut

The bestselling M&S Good Gut range now includes drinks, yogurts and shots made with an exclusive new M&S TriMarks blend of fibre, live cultures and Plenibiotic. Plus, if you want to introduce more plant foods into your diet, there are various fibre-rich cereals and breakfast toppers made with oats, barley and seeds.

These are just some of the latest products you can choose from.

How can fibre help?

“Fibre is a hidden hero in our diets, found in plant-based foods,” explains M&S Senior Nutritionist Louisa Brunt. “There are different types of fibre, each offering unique health benefits.”

For instance, beta-glucans, a type of fibre found in oats, help to maintain normal blood cholesterol levels and support regulating glucose after a meal. Meanwhile, fibre from oat grain and wheat bran helps add bulk to stools, and rye fibre contributes to normal bowel function.

“This January, fibre takes centre stage in our new Nutrient Dense range, as 96% of UK adults aren’t getting the recommended 30g per day*,” says Louisa. “So, we’re making it easier to increase your fibre intake with delicious options across the range.”

Introducing Nutrient Dense

The M&S Nutrient Dense range was created by in-house nutritionists and chefs, using nutrition guidelines developed in consultation with the British Nutrition Foundation. From speedy meals and salads to snacks and drinks, these products are made with whole foods and perfectly portioned to offer high amounts of nutrients – such as fibre, vitamins and minerals – per calorie.

Here’s a selection of top picks to help you hit your fibre goals.
