How to Pick the Right Bean for You

Choosing the right bean involves considering your specific dietary priorities. If you are a vegetarian or vegan focused on maximizing complete protein intake, soybeans (including edamame) are the clear winner. For those prioritizing digestive health, navy beans offer an exceptional fiber punch that promotes regularity and gut biome health. Athletes needing iron and a slow-release carbohydrate source may benefit most from lentils. For general cardiovascular health and blood sugar control, black beans and chickpeas are excellent choices due to their high fiber and antioxidant content.

Cooking with Your Chosen Bean

  • Soybeans: Often used in Asian cuisine, soybeans can be steamed and eaten as edamame, processed into tofu, or added to stir-fries.
  • Lentils: These cook quickly and are perfect for thickening soups, stews, and curries. Red lentils break down easily, while green or brown lentils hold their shape better.
  • Navy Beans: Their small size and creamy texture make them ideal for baked beans, dips, and hearty soups.
