Try all you want to avoid pesticides, sugar, and GMOs, you're still getting duped by confusing claims, hidden chemicals, and faux "healthy" labels.

Below, check out the cleanest (and dirtiest!) versions of your favorite foods. (Take back control of your eating—and lose weight in the process—with our 21-Day Challenge!)

Eggs
Hard-boiled eggs add protein and healthy fat to your salad and can help you absorb eight times more carotenoid antioxidants from veggies. But eggs produced by grain-fed chickens raised in cramped indoor cages aren't nearly as humane, nutritious, or safe as eggs produced by happy hens that roam freely in the sunshine and nosh on a natural diet. Here's how to make sense of the confusing labels.

Nuts
Adding the cleanest versions of these pint-size superfoods to your salad delivers up to 6 g of protein and 3 g of fiber per serving—way more than carb-heavy croutons or sugar-packed raisins. Nuts have even been shown to keep you so full that you eat less at your next meal, a phenomenon known as the second-meal effect. But keep it simple—the wrong choice can result in excess salt, sugar, and sketchy oils.

Dressing
Don't let a drizzle derail your dinner. You wouldn't put a bumper sticker on a Bentley, would you? Then why would you pour an unhealthy dressing on a first-class designer salad?

Protein
Lean, low-calorie protein that doesn't need to be cooked? That's one reason we love the cleanest canned fish, along with its heart-healthy omega-3 fatty acids. But some canned fish can be big on toxins like mercury, so choose your species wisely. Then opt for one that hasn't been packed in a can with BPA, a synthetic chemical linked to weight gain, heart arrhythmias, certain cancers, asthma, and other health problems. Look for "BPA-free" on the label.
