Episode FAQs
Are all ultra-processed foods unhealthy?
Not necessarily. Dr. Christopher Gardner explains that not all UPFs are equally harmful. Some foods labeled “ultra processed”, like certain tomato sauces or whole wheat breads, can still be part of a healthy diet in moderation.
What ingredients or additives should I avoid?
Look out for long ingredient lists filled with unpronounceable items, artificial dyes, flavorings, and industrial additives. The American Heart Association published a list of 150 ingredients to watch out for.
How can I make better choices at the grocery store?
Read ingredient labels carefully. Choose foods with shorter ingredient lists, recognize the first few ingredients, and be mindful of cosmetic additives.
