Abstract

Quinoa (Chenopodium quinoa Willd.) is a nutrient-rich grain native to South America and eaten worldwide as a healthy food, sometimes even referred to as a ”superfood”. Like quinoa grains, quinoa greens (green leaves, sprouts, and microgreens) are also rich in nutrients and have health promoting properties such as being antimicrobial, anticancer, antidiabetic, antioxidant, antiobesity, and cardio-beneficial. Quinoa greens are gluten-free and provide an excellent source of protein, amino acids, essential minerals, and omega-3 fatty acids. Quinoa greens represent a promising value-added vegetable that could resolve malnutrition problems and contribute to food and nutritional security. The greens can be grown year-round (in the field, high tunnel, and greenhouse) and have short growth durations. In addition, quinoa is salt-, drought-, and cold-tolerant and requires little fertilizer and water to grow. Nevertheless, consumption of quinoa greens as leafy vegetables is uncommon. To date, only a few researchers have investigated the nutritional properties, phytochemical composition, and human health benefits of quinoa greens. We undertook a comprehensive review of the literature on quinoa greens to explore their nutritional and functional significance to human health and to bring awareness to their use in human diets.

  • Amaranth is often reported with lysine contents of around 5.7-10.1 g/100 g protein and methionine of 3.0-4.7 g/100 g protein, supporting its applications to complementary formulations.

    “Amaranth is often reported with lysine contents of around 5.7-10.1 g/100 g protein and methionine of 3.0-4.7 g/100 g protein, supporting its applications to complementary formulations”

    From Structure-function design of amaranth, buckwheat and quinoa proteins as hydrocolloids for emulsion and gel structuring (2027) · cites this paper as Pathan & Siddiqui, 2022

    Sections 2.1 (Protein) and 2.5 (Essential Amino Acids) give lysine and methionine values for quinoa leaves; section 2.5 mentions amaranth only as a comparison for methionine. Searches for the stated amaranth ranges and complementary formulations found no passage addressing either point. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
