Processed Foods Aren’t the Enemy: Eating with Facts, Not Fear
Welcome back to the Gentle Gut Guide!
Today we’re breaking down processed & ultra-processed foods in a realistic, no-BS, evidence-based way.
If you’ve ever felt pressure to avoid anything “processed” or worried that eating packaged foods makes you “unhealthy,” this episode is for you. As a dietitian, I see more and more people feeling anxious about processed foods, and it’s seriously increasing stress & taking nuance out of eating.
Here’s the truth: processed doesn’t mean bad. In fact, many processed foods support health, help you meet nutrient needs, and make eating well more accessible, affordable, and sustainable.
In this episode, we’ll explore:-What “processed food” really means (and how many supportive foods fit the definition)
-A breakdown of the NOVA food classification system (& some critiques of it)
-Common additives like emulsifiers and gums, what the evidence actually says about their safety
-How fortification has improved public health
-Why food morality and “good vs bad” labels can impact your health goals long-term
-Practical tips for using processed foods to nourish yourself and simplify meals
Whether you’re juggling a busy schedule, budgeting for groceries, or just want peace of mind about what’s on your plate, this episode will help you think critically and eat with confidence without the fear.
