    Protein & Satiety

    Edamame
    Corn · 20Edamame · 95

    Edamame delivers a massive protein punch that keeps you full, while corn offers mostly starch with minimal protein.

    Tradeoff

    Choosing corn means relying on other foods to hit your protein targets, whereas edamame practically handles it on its own.

    Why it matters

    Protein is essential for staying full between meals and maintaining muscle, making edamame far more satisfying.

    Real-world impact

    A bowl of edamame will easily tide you over until your next meal, but a corn cob might leave you hunting for a snack an hour later.
