Soybeans are an extremely important source of protein. When you have enough proteins in your body, your metabolic functioning and the overall system will get a major boost, thus helping maintain your health better.

As per research published in the American Journal of Clinical Nutrition, isoflavones in soybeans help protect against spinal bone loss. Another study showed how soy isoflavones also help in preventing osteoporosis and improving overall bone strength, thereby reducing the risk of fracture.

Soybeans help in reducing sleep disorders and the occurrence of insomnia. They also have a high content of magnesium, as highlighted by researchers from the University of Kentucky in their study published in the journal Plant Physiology. Magnesium is directly linked to increasing the quality, duration, and restfulness of your sleep.
