According to a review of 14 studies, conducted by the Joanna Briggs Institute, Australia, high-dose sustained release vitamin C may reduce anxiety and mitigate increased blood pressure in response to stress (2).

The bioflavonoids present in mung sprouts also help protect against stress. During another 2016 study, scientists discovered that kidney bean sprouts could be a good source of dietary melatonin and other bioactive compounds that are known to have health benefits (3).

3. Packed with antioxidants

All bean sprouts contain impressive amounts of antioxidants. Antioxidants help neutralize the effects of disease-causing free radicals. Damage caused by free radicals has been linked to chronic inflammation, cancer, heart ailments, and other diseases.
