Nutritional powerhouse and complete protein
Amaranth is often celebrated as a "superfood" due to its dense nutritional profile, which includes a high concentration of plant-based protein. A single cup of cooked amaranth contains over 9 grams of protein, a significant amount for a plant-based food. What makes this protein exceptional is its completeness; unlike most other plant proteins, amaranth contains all nine essential amino acids, including a high level of lysine, which is crucial for building muscle mass and boosting the immune system. For those with gluten intolerance or celiac disease, amaranth offers a naturally gluten-free alternative to traditional grains like wheat, barley, and rye, providing a safe and nutritious option.
Essential vitamins and minerals
Beyond its protein content, amaranth is an excellent source of essential vitamins and minerals. It is particularly rich in manganese, which plays a vital role in brain function and metabolism. A single serving can meet a substantial portion of your daily manganese needs. It is also high in magnesium, which is involved in muscle contraction and DNA synthesis, as well as phosphorus, which is essential for strong bones. For those with anemia, amaranth's significant iron content can help increase hemoglobin and red blood cell counts. The leaves are also a good source of vitamins A, C, and K, contributing to vision, immunity, and bone health.
Anti-inflammatory and antioxidant properties
Chronic inflammation is a leading cause of many diseases, including heart disease, cancer, and diabetes. Research indicates that amaranth possesses potent anti-inflammatory properties that can help mitigate this risk.
Polyphenolic Antioxidants
The seeds and leaves of amaranth are packed with phenolic acids like gallic acid and vanillic acid, which act as powerful antioxidants. These compounds combat harmful free radicals, protecting cells from damage that can lead to chronic illness. Raw amaranth contains the highest level of antioxidants, though processing can slightly reduce their activity.
Bioactive Peptides
Amaranth protein contains bioactive peptides, including a lunasin-like peptide, which was first identified in soybeans and is believed to have anti-inflammatory and cancer-preventive benefits. These peptides work by reducing the body's production of pro-inflammatory markers.
Squalene
Amaranth oil is a unique plant-based source of squalene, a potent antioxidant that supports immune function and may protect against inflammation-related issues.
Benefits for heart and digestive health
Including amaranth in your diet can offer significant advantages for cardiovascular and digestive systems. Its rich fiber, healthy fats, and unique peptides work together to support overall well-being.
Cardiovascular support
- Cholesterol Reduction: Animal studies have demonstrated amaranth's cholesterol-lowering effects. It has been shown to reduce total and 'bad' LDL cholesterol, while potentially increasing 'good' HDL cholesterol. This is attributed to its fiber content and phytosterols, which interfere with cholesterol absorption.
- Blood Pressure Regulation: Amaranth peptides can help lower blood pressure by promoting relaxation of blood vessels. Its high potassium content further aids in regulating blood pressure, reducing strain on the cardiovascular system.
Digestive wellness
- Rich in Fiber: Amaranth is high in both soluble and insoluble fiber, which is essential for a healthy digestive system. This fiber helps prevent constipation and keeps bowel movements regular.
- Prebiotic Effects: The fiber acts as a prebiotic, feeding the beneficial bacteria in your gut. This fosters a healthy gut microbiome, which is linked to better immune function and overall health.
- Supports Gut Lining: By providing a good source of fiber, amaranth can help support the growth of beneficial gut bacteria, which in turn helps treat conditions like leaky gut syndrome by reinforcing the intestinal lining.

Conclusion: A versatile and healthful ancient grain
The medicinal benefits of amaranth are numerous and well-supported by nutritional science, making it a valuable addition to a modern diet. This versatile ancient grain and its components—including the seeds, leaves, and oil—offer a wealth of health-promoting properties. From its high-quality, complete protein for muscle and tissue repair to its fiber-rich content for digestive health, amaranth delivers substantial nutritional value. The presence of powerful antioxidants and anti-inflammatory peptides further helps protect the body against chronic diseases like heart disease and cancer. While animal studies show promising results for cholesterol reduction, more human research is needed. Easily incorporated into various dishes, amaranth's gluten-free nature also makes it a safe and nutritious choice for those with sensitivities. As interest in ancient grains grows, amaranth is reclaiming its rightful place as a staple for robust health. For further reading, consult the comprehensive review on amaranth's properties.
A list of amaranth's medicinal properties
Amaranth possesses numerous health benefits, including reducing inflammation and potentially lowering cholesterol, though more human studies are needed on the latter. It supports heart health due to its fiber, healthy fats, and potassium content. High in fiber, it aids digestion and fosters a healthy gut microbiome. Amaranth's protein and fiber content may also help with weight management. Rich in calcium, magnesium, and phosphorus, it contributes to bone strength. As a good source of iron, it can help combat anemia. Amaranth is naturally gluten-free and offers a complete protein source, containing all essential amino acids. It also acts as an antioxidant, protecting against free radical damage. Preliminary research suggests anti-cancer potential from compounds like lunasin.
What are the medicinal benefits of amaranth: Frequently Asked Questions
Is amaranth truly a "complete protein"?
Yes, amaranth is considered a complete protein because it contains all nine of the essential amino acids that the human body cannot produce on its own. It is particularly noted for its high concentration of lysine, an amino acid often lacking in other grains.
Can amaranth help with weight loss?
Yes, amaranth can aid in weight management due to its high fiber and protein content. Both nutrients promote a feeling of fullness, which can help reduce appetite and overall calorie consumption.
Is amaranth beneficial for heart health?
Numerous studies, particularly in animals, suggest amaranth supports heart health by helping to lower total and LDL ('bad') cholesterol levels. Its fiber, healthy fats, and peptides also contribute to cardiovascular wellness and blood pressure regulation.
Does amaranth have anti-inflammatory properties?
Yes, research shows amaranth contains bioactive peptides and antioxidants that can help reduce inflammation. Chronic inflammation is a factor in many diseases, making amaranth a valuable addition to an anti-inflammatory diet.
Is amaranth safe for people with celiac disease?
Yes, amaranth is naturally gluten-free and is a safe and nutritious grain alternative for individuals with celiac disease or gluten sensitivity.
