[Nutrient content in vegetable species from the Argentine Chaco]

Area of Science:

• Agricultural Science
• Nutritional Science
• Botany

Context:

• The Argentine Chaco region harbors diverse wild edible plants.
• Traditional knowledge of wild edibles is often underutilized in modern diets.
• Understanding the nutritional profile of wild edibles is crucial for food security and health.

Purpose:

• To conduct a comprehensive nutrient analysis of selected wild edible species from the Argentine Chaco.
• To compare the nutritional value of these wild species against commercially cultivated counterparts.
• To identify potential sources of essential macro- and micronutrients.

Summary:

• Nutrient composition (protein, lipids, fiber, ash, sugars, pectin, energy) and mineral content (Ca, Na, K, Mg, Fe, P) were determined for wild leaves (Rumex sp., Amaranthus quitensis, Taraxacum officinale), fruits (Morrenia odorata, Passiflora sp., Eugenia myrciantes), and pollen (Typha domingensis).
• Wild leaves demonstrated higher macronutrient concentrations and energy values (33–60 Kcal/100 g) than cultivated varieties like Swiss chard and spinach (14–30 Kcal/100 g).
• Amaranthus quitensis showed exceptionally high calcium, iron, and magnesium levels, while Rumex sp. was rich in ascorbic acid. Wild fruits generally surpassed cultivated apples in macronutrients and energy. Typha domingensis pollen exhibited a high energy value (287.7 Kcal/100 g) and rich nutrient profile.

Impact:

• Highlights the significant nutritional advantages of wild edible plants over cultivated options.
• Identifies specific wild species (e.g., Amaranthus quitensis, Rumex sp., T. domingensis pollen) as potent sources of essential nutrients.
• Provides valuable data for promoting the incorporation of wild edibles into diets for improved nutrition and potential food security in the region.
