Lentils
Benefit for Your Body: Bite for bite, lentils are the best source of vegetarian protein you can find, boasting more of the muscle-building nutrient than 3 ounces of salmon. Plus, they’ll satisfy more than 60 percent of your daily fiber requirement.
Planetary Perk: Ditch a beef burger just one day a week in favor of a filling veggie dinner where lentils are the stars, and it’s like taking your car off the road for 320 miles, according to the nonprofit Environmental Working Group. Lentils are the most planet-friendly source of protein, the group says, because they pack so much nutrition into a tiny package that doesn’t require nearly the amount of land, water, and other precious natural resources that are pumped into concentrated animal farms.
