#4 What Sugar-Free Labels Don’t Tell Your Gut

Sugar-free, high protein, low calorie: those are marketing claims, not gut health claims. Dr. Remina breaks down what ultra-processed foods are associated with in your gut microbiome, which additives researchers are watching (including a new preprint that is promising, not proven), and why a gut under pressure can show up as bloating, low mood and brain fog. No food guilt, just what to look for on the label. Want a closer look at your symptoms?

The additives quietly working against your gut

A 2025 review found ultra-processed foods, and their emulsifiers and sweeteners specifically, are associated with reduced gut microbial diversity and a weakened gut barrier.
