Health Risk: Beans can interfere with vitamin absorption

Some beans, like soybeans, contain substances that interfere with the absorption of beta carotene and vitamins B12 and D, according to an older study from the U.S. Department of Agriculture. The heat from cooking inactivates most of these substances, making vitamin absorption more likely. However, it’s still smart to compensate for potential vitamin loss by consuming plenty of fresh fruits and yellow or dark green veggies (to up your beta carotene) and lean meat (for vitamin B12).
