A snack can seem like a minor break in the day's eating, but nutritionists say the choice made at the moment of a craving can do far more than temporarily curb hunger. According to dietitians, the right snack can feed gut bacteria, help prevent constipation and support the digestive system overall, while also keeping energy levels steady and warding off the familiar afternoon slump.
The key, dietitians say, is choosing foods that satisfy hunger while also looking after the gut. Experts recommend picking a snack that combines protein and fibre, since this combination best supports gut health, helps stabilise blood sugar and prolongs the feeling of fullness.
Dietitians have put together nine suggestions that combine taste with beneficial nutrients, offering simple options for a more balanced gut microbiome.
Yoghurt, hummus and chia pudding
Yoghurt is one of the most popular and convenient probiotic foods that can be added to any meal. As a snack, each spoonful provides gut-friendly bacteria that support a more balanced and diverse gut microbiome. Dietitians suggest pairing it with fruit such as apple slices, berries or pear for extra prebiotic fibre.
A nutritious dip is also an easy way to eat more vegetables. A combination of hummus and edamame provides plant-based protein along with plenty of fibre.
Chia seed pudding, even in a small serving, has high nutritional value. It is a rich source of fibre and omega-3 fatty acids, both of which help support the gut. Dietitians suggest trying it with honey, fruit and nuts for an afternoon boost.
Roasted chickpeas and fermented foods
Roasted chickpeas are a healthy alternative to processed crisps. As well as being tasty and filling, they are also rich in fibre.
Fermented vegetables are an easy way to add probiotics to the diet between meals. Dietitians suggest pairing a fermented vegetable such as pickles with cheese or with lean meat, such as sliced turkey or chicken, for added protein.
Pistachios, prunes and walnuts
Pistachios are said to be particularly beneficial for the gut. A study cited by dietitians found that people with prediabetes showed a positive boost in their gut bacteria after eating pistachios every evening for 12 weeks. Pistachios are also a source of fibre, which helps prevent constipation. They are described as an easy, enjoyable and quick snack that can also be stirred into yoghurt or blended into a smoothie.
Dried prunes have unfairly gained a reputation as an old-fashioned food, dietitians say, even though they are packed with nutrients and particularly beneficial for gut health. They contain both insoluble and soluble fibre, which can support gut bacteria, as well as sorbitol, a natural sugar alcohol that can ease bowel movements.
Dietitians recommend pairing prunes with walnuts, which are rich in omega-3 fatty acids and fibre. Studies show that walnuts, too, can help support gut bacteria.
Dates with dark chocolate and kefir smoothies
For those looking for a sweet snack, dietitians suggest dates. They contain fibre and, according to studies, can contribute to more regular bowel movements. Dietitians recommend pairing them with dark chocolate and a sprinkle of salt for extra flavour.
Kefir contains probiotic cultures that can support a more balanced and diverse gut microbiome, as well as regular digestive function. A smoothie made with kefir, along with fruit and vegetables, makes for a more filling snack option.
What else to watch out for
Experts advise avoiding heavily processed snacks that contain added sugars, artificial sweeteners and emulsifiers, as these can increase the risk of disrupting the gut microbiome.
As with any meal, it is preferable to choose whole or minimally processed foods. Dietitians note that snacks are a good opportunity to fill any nutritional gaps that arise during the day.
Timing also plays an important role. Dietitians recommend leaving three to four hours between eating occasions to support the digestion process.
