Abstract

Quinoa (Chenopodium quinoa Willd.) and amaranth (Amaranthus cruentus L.) are pseudocereal grains rich in both macronutrients and micronutrients including vitamins and minerals. The proteins are particularly of high nutritional quality due to the outstanding balance of essential amino acids. However, recent research strongly suggests that nonessential nutrients such as phytochemicals of quinoa and amaranth may also have potential health beneficial effects. This review focuses on the phytochemical composition of quinoa and amaranth seeds, the antioxidant and anti-inflammatory activities of hydrophilic (e.g. phenolics, betacyanins) and lipophilic (e.g. fatty acids, tocopherols, and carotenoids) nutrients, and how these contribute to the potential health benefits, especially in lowering the risk of the oxidative stress related diseases e.g. cancer, cardiovascular disease, diabetes, and obesity. The gap between current knowledge and future research needs have also been identified.

Quinoa - a Review

Quinoa is a nutritious pseudocereal with high nutritional value, providing essential amino acids, vitamins, and minerals for a healthy diet.

Pharmacokinetic study of amaranth extract in healthy humans: A randomized trial.

A single oral dose of amaranth extract significantly increases nitric oxide (NO) levels in the body for at least 8 hours, potentially improving performance in vigorous physical activities or sports.

Distribution of phenolic antioxidants in whole and milled fractions of quinoa and their inhibitory effects on α-amylase and α-glucosidase activities.

Whole grain quinoa and its milled fractions contain phenolic antioxidants, which can promote health and serve as functional food ingredients in gluten-free foods.

A comparison of the bioactivity and phytochemical profile of three different cultivars of globe amaranth: red, white, and pink.

Globe amaranth cultivars red, white, and pink show high antioxidant and anti-inflammatory properties, with no liver cell toxicity observed.

Bound Phenolics of Quinoa Seeds Released by Acid, Alkaline, and Enzymatic Treatments and Their Antioxidant and α-Glucosidase and Pancreatic Lipase Inhibitory Effects.

Hydrolysis of quinoa seeds releases bound phenolics, which show stronger antioxidant and anti-inflammatory effects, with black quinoa having the highest concentration.
