Amaranth is argued to have diversely healthful effects, particularly regarding bone development, vision, varicose veins, digestion and weight loss. It is also thought to increase antioxidant activity that can lower inflammation and combat free radicals, the molecules that often instigate the development of cancer cells.
Amaranth is rich in minerals that promote bone health and development, particularly calcium, making it a potentially ideal supplement for those suffering from osteoporosis or other demineralizing conditions. Amaranth also contains abundances of fiber and vitamin K, substances known to either help with the reduction of bad cholesterol or to boost cardiovascular health more broadly. This high fiber content also makes amaranth a potential supplement for digestive health.
Amaranth is a significant source of protein, and offers an alternative to animal-based protein sources that may also be higher in fat. Additionally, amaranth contains high levels of both vitamin A and carotenoids, substances known to enhance eye health and stave off visual impairments such as cataracts and macular degeneration. Some researchers also believe amaranth can prevent certain birth defects, especially folate deficiency, due to its ample store of minerals.
Regarding weight loss, amaranth's high protein delivery arms it to help release "sated" in the body, a protein scientists suspect may suppress appetite, a tool some dieters consider. Of course, the addition of amaranth to anyone's diet for any medical or otherwise health-oriented reason should always be effected in coordination with a physician.
