Amaranths are branching broad-leaved plants with egg-shaped or rhombic leaves which may be smooth or covered in tiny hairs. The leaves have prominent veins, can be green or red in color and have long petioles. The plants produce single flowers on terminal spikes which typically red to purple in color.Amaranth plants typically are annuals or short-lived perennials. The stems often are reddish in colour and sometimes are armed with spines; they bear simple alternately arranged leaves and often feature a pinkish taproot.Amaranth is a nutritious, gluten-free grain that provides plenty of fiber, protein and micronutrients. It has also been associated with a number of health benefits, including reduced inflammation, lower cholesterol levels and increased weight loss.Although amaranth is categorized as a grain, it's really a seed (just like quinoa). The tiny seeds are about the size of sesame seeds and have a yellowish color. The seeds can be used whole or ground into flour. They have a sweet and nutty flavor and are a bit crunchy when cooked.
