Antioxidant and Antidepressant Benefits of Proteins from Egg and Bean Extracts and Their Toxicity Insights: A Journey Through Nutrition and Pharmacognosy
Exploring the Antioxidant and Antidepressant Properties of Protein Extracts from Eggs and Beans
Recent research has shed light on the potential health benefits of dietary proteins derived from natural sources such as eggs and beans. This study, published in IgMin Research (Full Text, PDF), delves into the antioxidant and antidepressant properties of these protein extracts, offering a fresh perspective on how nutrition can impact mental health.
The Role of Dietary Proteins in Mental Health
Proteins are essential nutrients that play a crucial role in various physiological processes, including mood regulation and neurotransmitter synthesis. In recent years, studies have focused on the potential of dietary proteins to influence mental health, particularly in mitigating symptoms of depression. The current research takes this exploration further by examining protein extracts from eggs and beans, both in their denatured and non-denatured forms.
Antioxidant Activity: DPPH and Hydrogen Peroxide Tests
The study utilized two key assays to evaluate the antioxidant potential of egg and bean protein extracts: the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay and the hydrogen peroxide (H2O2) scavenging test. The results indicated that both egg and bean extracts possess significant antioxidant properties, particularly when denatured. For instance, denatured bean protein extracts at 80% saturation exhibited a lower IC50 value in the H2O2 test, suggesting stronger antioxidant capabilities compared to other extracts.
However, the DPPH assay results were inconclusive due to the precipitation of proteins in the ethanol-based reaction medium, which affected the accuracy of the readings. Despite this limitation, the H2O2 test confirmed the extracts’ potential to neutralize free radicals, highlighting their role in combating oxidative stress.
Antidepressant Properties: Acute and Chronic Depression Tests
The research also focused on the antidepressant effects of these protein extracts using mouse models. Two main tests were employed: the forced swim test (FST) to assess acute antidepressant effects and the sucrose preference test for evaluating the extracts’ impact on chronic mild depression.
In both tests, protein extracts at higher saturation levels (80%) demonstrated significant reductions in depression-like behaviors. Notably, the denatured extracts showed a more pronounced effect, suggesting that processing these proteins enhances their bioactivity. Mice treated with these extracts exhibited increased activity levels and a higher preference for sucrose, indicative of reduced depressive symptoms.
Safety and Toxicity Findings
The safety of these protein extracts was also a critical aspect of the study. The acute toxicity tests revealed that egg protein extracts at both 40% and 80% saturation levels are non-toxic, with no adverse effects observed even at high doses. Conversely, bean protein extracts at 80% saturation displayed mild toxicity at higher doses, with a calculated LD50 value of 2.5 g/kg body weight. This highlights the importance of dosage considerations when using such extracts for therapeutic purposes.

Potential Implications for Mental Health Treatments
The findings from this study suggest that protein extracts from common dietary sources like eggs and beans could serve as natural agents for supporting mental well-being. Their ability to act as antioxidants and influence depression-related behaviors makes them promising candidates for further research in nutraceuticals and pharmacognosy. By leveraging the natural properties of these extracts, researchers hope to develop new, safer alternatives to traditional antidepressants.

Conclusion
The study of antioxidant and antidepressant properties in dietary proteins offers a new perspective on the intersection of nutrition and mental health. While more research is needed to translate these findings into clinical applications, the potential of natural protein extracts to support mental well-being is both exciting and promising. As science continues to explore these connections, natural remedies derived from everyday foods could become key players in the treatment of mental health conditions.
