Some of us (guilty!) are capable of putting away an entire batch of gooey, chocolatey brownies in one sitting. Hey, it happens. Present me with a tray boasting bittersweet chocolate, sugar, and butter, and I’ll show up with the oven mitts, ready to dig in.

Research has shown that compared to wheat, rye triggers a lower insulin response, boosts post-meal fullness, and can result in naturally eating less at the following meal, she adds. (Just remember that rye is not gluten-free. “If you have celiac disease or gluten sensitivity, rye is off the menu,” says Sass.)RELATED: 13 Sugar-Free Dessert Recipes That Will Actually Satisfy Your Sweet ToothUnfortunately, even the addition of rye flour doesn’t exactly transform brownies into a health food.
