Soaking nuts can make nuts easier to digest. It helps to remove or break down some of the substances in nuts that can make them difficult to digest, such as phytic acid and tannins. It also helps to improve the texture and taste of nuts, making them softer and more flavorful.
Soaking also helps activate certain enzymes that can improve the absorption of certain nutrients. Some research suggests that soaking nuts may also increase their levels of certain antioxidants, such as phenols and flavonoids.
