Herbs for the service of man and why Pairwise's new gene altered mustard green is not wise.

Numbers 9:11 "The fourteenth day of the second month at even they shall keep it, and eat it with unleavened bread and bitter herbs."
Psalms 104:14 “He causeth the grass to grow for the cattle, and herb for the service of man: that he may bring forth food out of the earth.”
Recent advancements in gene editing have made it possible to alter crops for specific traits. For instance, the gene edited mustard greens developed by Pairwise, funded by Monsanto, aim to reduce bitterness. While this may seem appealing, it will lead to disastrous outcomes and reflects a significant regulatory failure.
Bitterness and Health in Mustard Greens
Bitterness in mustard greens, like in other leafy vegetables, stems from health-promoting compounds known as glucosinolates. These sulfur based chemicals, found in cruciferous veggies, are celebrated for their antioxidant properties. Why are antioxidants essential? Because they help neutralize harmful free radicals and support overall health.
Antioxidants: A Health Imperative
Antioxidants protect cells, reduce inflammation, and lower the risk of chronic diseases such as heart disease, cancer, and diabetes. Shouldn't we perceive bitterness as a sign of these crucial compounds rather than a flavor to be eliminated?
Risks of Reducing Bitterness
Could the gene editing aimed at reducing bitterness compromise the health benefits of mustard greens?
-
Loss of Glucosinolates: Diminishing bitterness will decrease glucosinolates, thereby reducing the antioxidant capacity of the greens. Is the trade off worth sacrificing health benefits?
-
Nutritional Disruption: What are the implications of altering the natural composition of mustard greens? Could this disrupt the nutrient balance and diminish their health advantages? I strongly believe it would.
Broader Implications to Consider
Beyond immediate health concerns, what are the broader effects of gene editing in agriculture?
-
Biodiversity Risks: Could the preference for gene edited crops threaten biodiversity? Might traditional mustard greens be neglected, risking genetic diversity that is crucial for resilience against pests and diseases?
-
Ethical and Environmental Concerns: What ethical questions arise from modifying natural organisms? What environmental consequences might emerge, such as impacts on soil health and ecosystems?
Conclusion
Is it truly wise to eliminate bitterness from mustard greens? The potential decrease in antioxidant benefits, alongside the broader implications of gene editing, prompts us to reflect on the true purpose of altering these naturally nutritious plants. Embracing their inherent bitterness, along with its health benefits, is a wiser choice for both personal and ecological well being.
