How Sugar Affects Gut Health

We know sugar can leave us feeling tired, sluggish and moody, but did you know it can cause long-lasting damage to your gut microbiome? Inflammation, poor digestion and constipation are the trifecta of signs something’s amiss – we’ll be unpacking how sugar affects gut health and what you can do to prevent or reduce the severity of symptoms.

Sugar and the gut microbiome

The gut microbiome is a structure of trillions of bacteria, all of which influence our gut health, we’ve even got studies showing our gut bacteria can influence the kinds of cravings we have. Luckily, we have some control over the balance of these bacteria and what eat plays a massive role in promoting the growth of good bacteria.

How sugar promotes the growth of bad bacteria

The research shows that sugar promotes the growth of a number of bad bacteria and reduces the ability of the good guys to thrive. It also reduces the diversity of gut bacteria, causing the scale to tip in favour of gut-damaging bacteria. Studies show higher levels of Proteobacteria exist in those with high-sugar diets, and this is a known indication of dysbiosis – an unbalanced microbiome. On top of affecting gut health, this can also lead to mental health issues and autoimmune conditions.

How sugar causes bloating and constipation

A whopping 50% of Aussies deal with disruptive gut issues like bloating, wind and constipation, with 1 in 7 of us battling more severe cases – so it’s no wonder so many are keen to hack their microbiome to find some relief. Bloating describes an excessively full or stretched feeling in the stomach that may also be accompanied by cramping, burping, wind, diarrhoea and constipation. The reason behind this common ailment comes down to the organs of the digestive system being stretched themselves, often as a result of gas, liquids or solids building up in the gut. But there are a few other internal workings that can cause this uncomfortable feeling, including a slow movement of food through the digestive system.

You’re more likely to experience bloating if you’ve eaten a sugary or fatty meal, along with eating too fast – this can lead to swallowing air, resulting in gas and bloating. We know sugar affects the gut microbiome, and in turn, this dysregulation can also be to blame for long-term bloating. Diarrhoea and indigestion are also commonly experienced for those with a haywire microbiome.

What you can do to improve gut health

The first thing you’ll want to do is limit or cut out inflammatory foods like added sugars, deep-fried foods and alcohol – but it’s also important to replace these foods with nourishing ingredients too:

  • Whole foods: Fruits, veggies and grains in their whole form are loaded with fibre for bowel movement regularity and good digestion, helping to prevent constipation and bloating. They also slow the metabolisation of sugar, reducing the risk for blood-sugar spikes that come with ultra-processed foods. Around 83% of Aussies aren’t meeting their fibre intake needs, with research showing we need to boost our intake by 30% to meet the daily target of 28 grams.
  • Healthy fats: These fats not only promote gut health, they also help us process nutrients like vitamins A, D and E, along with maintaining healthy blood-sugar levels and healthy digestion. Avocados, olive oil and walnuts are your friends here!
  • Probiotics: It’s all about gut bacteria! Probiotics are a great way to introduce healthy bacteria to your gut, but remember the whole grains and veggies are also essential to ensure those probiotics thrive. It’s a group effort! Tempeh, yoghurt and sauerkraut are all great options. 

  • Protein: Getting enough protein is important to keep us feeling satiated and to reduce those sugar cravings that are sure to crop up when we go cold turkey on the sweet stuff. Foods like egg, tofu, natto and legumes are all great choices to keep your protein intake up.
