Amaranth flour is a type of flour that is made from the amaranth plant, which is a gluten-free pseudocereal. It has a nutty and earthy flavor and is a good source of protein, fiber, and micronutrients such as iron, magnesium, and calcium.
In protein powders, amaranth flour is often added as a source of plant-based protein and to enhance the overall nutritional profile of the product.
In terms of safety, amaranth flour is generally considered safe for consumption by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, individuals with celiac disease or gluten sensitivity should avoid amaranth flour or any other grains that contain gluten-like proteins, as they can trigger an immune response and cause symptoms such as bloating, diarrhea, and abdominal pain.
