Amaranth flour is obtained by grinding the grains of the plant of the same name, belonging to the Amaranthaceae botanical family. This ancient grain has become increasingly valued for its nutritional qualities, which are comparable to those of quinoa. One of its main advantages is that it is gluten-free, making it an excellent option for people with celiac disease or gluten sensitivity. In addition, it is rich in essential amino acids, such as lysine, which plays a key role in calcium absorption, muscle mass formation, and energy production. Amaranth also contains natural oils and phytosterols that help reduce blood cholesterol levels, especially LDL cholesterol and triglycerides. Additionally, its peptides and essential oils possess anti-inflammatory and analgesic properties, which can help reduce pain and inflammatory processes in the body. This food stands out for its antioxidant power, which protects cells from damage caused by free radicals. At a mineral level, it is a rich source of calcium, magnesium, copper, zinc, potassium, and phosphorus, essential nutrients for strengthening bones, proper muscle function, hydration, and maintaining body energy. Finally, its high fiber content promotes healthy digestion, contributes to intestinal balance, and helps maintain adequate cholesterol levels. Overall, amaranth flour is a nutritious, functional food suitable for a balanced diet.
