Just two teaspoons of this rich spice and you get a little over three grams of fiber. And fiber should be part of your healthy eating plan if you’re considering losing weight. Cardamom also serves as a diuretic, removing toxins, waste, and anything in excess from your body. It also improves digestion and controls blood pressure. Combine this aromatic spice with beans, soups and veggies, or add it to your chai tea.
