Popular Health Foods That Are Actually Junk in Disguise

35. Avocado Oil Mayo: Healthier, But Not Free-For-All

Avocado oil mayo is often perceived as a health-forward upgrade from regular mayo—and in some ways, it is. It typically contains heart-healthy monounsaturated fats. But it’s still calorie-dense, and many brands sneak in soybean oil, sugar, or preservatives alongside the avocado oil. Plus, a tablespoon can add up quickly on sandwiches or in salads. It’s a better option in moderation, but not a free pass to slather. Check the ingredient list for purity—avocado oil should be the first or only oil—and use it sparingly, as you would any dressing or condiment with a health halo.

36. Rice-Based Snacks (Crisps, Crackers, Cakes): Not So Innocent

Rice-based snacks like crisps or thin crackers are often seen as light, gluten-free alternatives to wheat-based options. But they’re usually made with refined white rice, offering little fiber or protein—and they often come with a hit of added salt, oils, and sometimes even sugar. Their high glycemic index means they digest quickly and spike blood sugar, leaving you hungry soon after. Flavored varieties can be particularly deceptive, containing MSG, artificial additives, or sweet coatings. Don’t be fooled by their delicate crunch—these snacks are better viewed as occasional treats, not everyday staples.
