It used to come in winters of Delhi, place where I grew up and always hated it. It turns out its seed are gluten less and more nutritious than wheat.
Read on more about this wonder grain-Amaranth or Rajageera
Amaranth has a "sticky" texture that contrasts with the fluffier texture of most grains and care should be taken not to overcook it as it can become "gummy." Amaranth flavor is mild, sweet, nutty, and malt like, with a variance in flavor according to the variety being used.
Amaranth keeps best if stored in a tightly sealed container, such as a glass jar, in the refrigerator. This will protect the fatty acids it contains from becoming rancid. The seeds should be used within 3 to 6 months.
The leaves of the amaranth plant taste much like spinach and are used in the same manner that spinach is used. They are best if consumed when the plant is young and tender.
Amaranth seed is high in protein (15-18%) and contains respectable amounts of lysine and methionine, two essential amino acids that are not frequently found in grains. It is high in fiber and contains calcium, iron, potassium, phosphorus, and vitamins A and C.
The fiber content of amaranth is three times that of wheat and its iron content, five times more than wheat. It contains two times more calcium than milk. Using amaranth in combination with wheat, corn or brown rice results in a complete protein as high in food value as fish, red meat or poultry.
Amaranth also contains tocotrienols (a form of vitamin E) which have cholesterol-lowering activity in humans. Cooked amaranth is 90% digestible and because of this ease of digestion, it has traditionally been given to those recovering from an illness or ending a fasting period. Amaranth consists of 6-10% oil, which is found mostly within the germ. The oil is predominantly unsaturated and is high in linoleic acid, which is important in human nutrition.
The amaranth seeds have a unique quality in that the nutrients are concentrated in a natural "nutrient ring" that surrounds the center, which is the starch section. For this reason the nutrients are protected during processing. The amaranth leaf is nutritious as well containing higher calcium, iron, and phosphorus levels than spinach.
