Antioxidant and Free Radical Defence:

Quinoa is rich in antioxidants like phenolic acids and betalains, which help neutralize free radicals, reduce oxidative stress, and protect brain cells from damage. Its strong antioxidant activity supports its role in brain health and combating neurodegenerative diseases.

Neuroprotection:

Quinoa extracts, particularly from the Titicaca and Moqu Arochilla varieties, have demonstrated the ability to inhibit enzymes like acetylcholinesterase and butyrylcholinesterase, which are involved in neurodegeneration. This neuroprotective effect makes quinoa a promising food for supporting cognitive function and potentially preventing Alzheimer's disease.

Anti-Diabetic Properties and Glycemic Control:

Quinoa is beneficial for blood sugar regulation, showing significant α-glucosidase and α-amylase inhibition. This, along with its low glycemic index, helps manage blood sugar levels, making quinoa a valuable food for diabetes management.

Nutrient-Rich, Gluten-Free:

As a gluten-free pseudocereal, quinoa is packed with protein, fiber, essential amino acids, vitamins, and minerals. It also contains saponins and phytochemicals that support cardiovascular health, digestive function, and immune strength.
