For years, certain “health food” products have been promoted as miracle solutions for weight loss, better digestion, and overall wellness. Shoppers stocked their pantries with these items, trusting bold packaging claims and viral endorsements. But behind the scenes, the FDA has quietly shifted its stance on some of these trends—removing approvals, issuing warnings, or cracking down on misleading labels. The change isn’t always widely publicized, meaning many people are still buying these products, believing they carry the same credibility they once did. Here are five health food trends that have lost FDA backing, and why you might want to think twice before adding them to your cart.
1. Alkaline Water for Disease Prevention
Alkaline water was heavily marketed as a way to balance the body’s pH, fight disease, and even slow aging. While it’s still safe to drink in moderation, the FDA has never approved these health claims and has warned companies against marketing it as a medical treatment. Scientific evidence shows that your body naturally regulates its pH regardless of what you drink. The FDA has issued letters to several alkaline water brands for promoting unsubstantiated disease prevention claims. At the end of the day, staying hydrated is beneficial—but plain filtered water works just as well for most people.
2. CBD-Infused Food and Drinks
The explosion of CBD-infused products—everything from sparkling water to protein bars—hit shelves before regulations caught up. Initially, many believed CBD could be freely added to foods and beverages, but the FDA has since clarified that CBD is not approved as a food additive. Companies making health claims about CBD’s ability to treat anxiety, pain, or sleep disorders have received warning letters for misleading consumers. While research on CBD’s potential benefits continues, current FDA rules prohibit selling it in interstate commerce as a dietary supplement or adding it to food. If you’re buying CBD products, be aware that the legality and safety claims can vary widely.
3. Activated Charcoal as a Detox Ingredient
Activated charcoal once gained a reputation as a powerful detox agent, showing up in juices, smoothies, and even ice cream. But the FDA has pushed back on its use in foods, particularly in states like New York, where it’s banned in eateries due to safety and labeling concerns. While charcoal can bind to certain toxins in medical settings, it can also block the absorption of essential nutrients and medications. The FDA has cautioned against marketing it as a general detox solution, citing a lack of scientific evidence for these benefits in healthy individuals. What started as a trendy health boost is now off-limits in many regulated food settings.
4. Raw Milk for Health Benefits
Raw milk advocates have long claimed it’s more nutritious and beneficial than pasteurized milk. However, the FDA strongly advises against drinking raw milk, citing the risk of serious illnesses caused by bacteria like E. coli, Salmonella, and Listeria. While it’s legal in some states, interstate sale of raw milk is prohibited under federal law. The FDA has doubled down on warnings after several outbreaks were linked to raw dairy products in recent years. Despite its niche popularity, raw milk remains one of the most heavily discouraged “natural” health foods on the market.
5. Colloidal Silver Supplements
Colloidal silver products were once sold with claims of boosting immunity, fighting infections, and even treating chronic diseases. The FDA has taken a hard stance against these claims, warning that colloidal silver is not safe or effective for any health condition. Ingesting it can cause serious side effects, including argyria—a permanent bluish-gray discoloration of the skin. The agency has sent multiple warning letters to companies marketing silver as a dietary supplement or medical cure. Despite being available online, colloidal silver is no longer recognized as a safe health product by the FDA.
Shifting Science Means Shifting Guidelines
Health food trends often rise on the back of promising early studies, celebrity endorsements, and aggressive marketing. But as more research comes in, the FDA’s stance can change—sometimes quietly, sometimes with strong public warnings. For consumers, the takeaway is clear: just because something was once hyped as healthy doesn’t mean it still carries regulatory support. Staying informed about FDA updates can help you avoid wasting money or risking your health. When in doubt, focus on well-established, evidence-based nutrition choices over fleeting trends.
