In addition, we will also discover some delicious ways to incorporate it into your daily meals.

What Is Amaranth?

Amaranth (Amaranthus) isn’t technically a grain but a pseudocereal – a plant that produces fruits or seeds consumed as grains, though botanically they are neither grasses nor true cereal grains. This ancient crop has been cultivated for thousands of years, originating in Mesoamerica, where it was a staple food for the Aztecs and Incas.

The plant itself is impressive, growing up to 6-8 feet tall with vibrant flowers ranging from deep red to gold. There are over 60 species of amaranth, but only three are commonly cultivated for their edible seeds: Amaranthus caudatus, Amaranthus cruentus, and Amaranthus hypochondriacus.

What makes amaranth particularly special is its remarkable resilience. It thrives in poor soil conditions, requires little water, and can withstand extreme temperatures. This adaptability has made it an increasingly important crop in the face of climate change and food security challenges.

In 2025, amaranth has gained significant popularity in Western diets as more people seek nutrient-dense, sustainable food options. Its tiny seeds (about the size of poppy seeds) pack an impressive nutritional punch that rivals – and in many cases exceeds – conventional grains.

Nutritional Profile of Amaranth

Amaranth’s exceptional nutritional content is what truly sets it apart from other grains and pseudocereals. Let’s break down what makes this ancient food so valuable:

Macronutrients (per 1 cup cooked/246g)

*Based on a 2,000-calorie diet

Micronutrients (per 1 cup cooked/246g)

*Based on a 2,000-calorie diet

Protein Quality

What makes amaranth’s protein content particularly impressive is its amino acid profile. Unlike most plant proteins, amaranth contains all nine essential amino acids, including lysine, which is typically lacking in most grains. This makes it a complete protein source – a rare quality in plant foods.

The protein digestibility-corrected amino acid score (PDCAAS) for amaranth is approximately 0.75, which is higher than most plant proteins and comparable to some animal proteins.

Unique Compounds

Beyond standard nutrients, amaranth contains several bioactive compounds that contribute to its health benefits:

• Squalene: A compound typically found in olive oil and shark liver oil, with potential antioxidant and cancer-fighting properties
• Phytosterols: Plant compounds that can help lower cholesterol levels
• Amaranthine: A pigment with potent antioxidant properties

18 Amazing Health Benefits of Amaranth

Let’s explore the most significant ways amaranth can contribute to your well-being:

1. Supports Heart Health

Amaranth contains several compounds that may benefit cardiovascular health. Its phytosterols can help lower LDL (bad) cholesterol levels by reducing cholesterol absorption in the intestines. Additionally, amaranth oil contains squalene, which studies suggest may help reduce cholesterol production in the liver.

A study found that consuming amaranth regularly was associated with reduced total cholesterol and triglyceride levels. The fiber content in amaranth also contributes to heart health by helping to remove excess cholesterol from the body.

2. Provides Complete Protein

Amaranth stands out from most plant foods by offering a complete protein containing all nine essential amino acids. It’s particularly rich in lysine, an amino acid often limited in cereal grains. This makes amaranth an excellent protein source for those following plant-based diets.

With approximately 9g of protein per cup of cooked amaranth (compared to about 5g in rice), it provides significant protein without the saturated fat found in many animal sources. The quality of amaranth protein is comparable to casein (milk protein) in its ability to support growth and tissue repair.

3. Supports Digestive Health

With nearly 5g of fiber per cup of cooked amaranth, this grain supports digestive health in multiple ways. Its insoluble fiber promotes regular bowel movements and helps prevent constipation, while its soluble fiber acts as a prebiotic, feeding beneficial gut bacteria.

Research suggests that the resistant starch in amaranth ferments in the colon, producing short-chain fatty acids that nourish colon cells and may help prevent colorectal cancer. Regular consumption of amaranth has been associated with improved gut microbiome diversity, a key factor in digestive and overall health.

4. Rich in Antioxidants

Amaranth contains several potent antioxidants, including rutin, gallic acid, and vanillic acid. These compounds help neutralize free radicals in the body, potentially reducing oxidative stress and cellular damage linked to chronic diseases and aging.

The rutin in amaranth has been shown to strengthen blood vessels and may help with conditions like varicose veins and hemorrhoids. Its antioxidant profile exceeds that of many common grains, helping to protect cells from oxidative damage.

5. Supports Bone Health

Amaranth is an excellent source of calcium, magnesium, and phosphorus – minerals essential for building and maintaining strong bones. One cup of cooked amaranth provides about 116mg of calcium (12% of the daily recommended intake), making it a good plant-based calcium source.

Additionally, amaranth contains lysine, which helps enhance calcium absorption and reduce calcium excretion. The balanced mineral profile in amaranth may help prevent osteoporosis and support overall bone density. This is particularly important for women, who face higher risks of bone density loss with age.

6. Helps Manage Diabetes

The complex carbohydrates and fiber in amaranth result in a lower glycemic index compared to many refined grains. This means amaranth causes a slower, steadier rise in blood sugar rather than the spikes that can be problematic for people with diabetes.

Research suggests that amaranth consumption may improve insulin sensitivity and help regulate blood glucose levels. A study found that incorporating amaranth into the diet improved glycemic control in participants with type 2 diabetes.

7. Supports Weight Management

Despite being nutrient-dense, amaranth can support weight management goals through several mechanisms. Its high protein and fiber content promote satiety, potentially reducing overall calorie intake by helping you feel fuller longer.

The resistant starch in amaranth may also support weight management by improving insulin sensitivity and promoting fat oxidation. Additionally, amaranth provides sustained energy without the blood sugar crashes that can lead to cravings and overeating.

8. Reduces Inflammation

Chronic inflammation underlies many modern diseases, from arthritis to heart disease and cancer. Amaranth contains several anti-inflammatory compounds, including peptides, phytosterols, and antioxidants, that may help reduce inflammatory markers in the body.

Research found that amaranth peptides exhibited significant anti-inflammatory activity in laboratory studies. Regular consumption may help manage inflammatory conditions and support overall immune balance.

9. Supports Immune Function

The impressive mineral content of amaranth, particularly its zinc, iron, and selenium, plays a crucial role in supporting immune function. These minerals help the body create and maintain immune cells and produce antibodies.

Additionally, amaranth contains lysine, which is essential for antibody production and supports the body’s ability to fight infections. Its vitamin C content, though modest, also contributes to immune defense and antioxidant protection.

10. Gluten-Free Alternative

For those with celiac disease, non-celiac gluten sensitivity, or wheat allergies, amaranth provides a nutritious, gluten-free alternative to wheat and other gluten-containing grains. Unlike many processed gluten-free products, amaranth offers superior nutritional value.

Its high protein, fiber, and micronutrient content make it an ideal choice for those on restricted diets who want to ensure adequate nutrition. Amaranth can be used to enhance the nutritional profile of gluten-free baked goods and other preparations.

11. Supports Brain Health

The iron and B vitamins in amaranth are essential for cognitive function and brain health. Iron helps transport oxygen to the brain, while B vitamins support neurological function and help produce neurotransmitters.

Regular consumption of iron-rich foods like amaranth may help prevent cognitive decline and support overall brain function, especially in those at risk for iron deficiency. Its complete amino acid profile also provides the building blocks needed for neurotransmitter production.

12. Enhances Athletic Performance

The complete protein profile of amaranth makes it an excellent food for athletes and those with active lifestyles. Its lysine content supports calcium absorption and tissue repair, while its carbohydrate content provides sustained energy.

The minerals in amaranth, including magnesium and potassium, support muscle function and help prevent cramping during physical activity. Many athletes incorporate amaranth into their pre-workout meals for sustained energy without digestive discomfort.

The phospholipids and antioxidants in amaranth may help support liver function and protect against liver damage. Some research suggests that amaranth consumption may help reduce fatty liver disease risk by improving lipid metabolism.

Its choline content also supports liver health by helping transport fats away from the liver, potentially preventing fatty liver disease. The fiber in amaranth aids the liver’s detoxification processes by ensuring toxins are efficiently removed through the digestive system.

14. Improves Skin Health

The vitamin E and essential fatty acids in amaranth support skin health by maintaining cell membrane integrity and protecting against UV damage. Its protein content provides the building blocks for collagen, essential for skin elasticity and youthful appearance.

The zinc in amaranth helps with tissue repair and may aid in managing skin conditions like acne. Some traditional cultures have used amaranth topically to treat inflammation and as a component in natural skincare formulations.

15. Supports Healthy Pregnancy

The folate content in amaranth is valuable for pregnant women, as this B vitamin helps prevent neural tube defects in developing fetuses. Its iron content also helps prevent anemia, a common concern during pregnancy.

With approximately 54 micrograms of folate per cup of cooked amaranth, it can contribute significantly to meeting the increased folate needs during pregnancy. Its complete protein profile also supports the rapid tissue development occurring during pregnancy.

16. Helps Lower Blood Pressure

The potassium in amaranth helps counterbalance sodium’s effects on blood pressure by relaxing blood vessel walls and increasing sodium excretion. Several studies have shown that diets rich in potassium can help reduce blood pressure in people with hypertension.

Additionally, certain peptides in amaranth may have ACE-inhibitory effects similar to certain blood pressure medications, though in a milder form. Regular consumption may contribute to maintaining healthy blood pressure levels as part of a balanced diet.

17. Supports Hormone Balance

The vitamin E and essential fatty acids in amaranth support hormone production and balance. Its magnesium content helps regulate cortisol levels, potentially reducing stress and its negative impacts on hormonal health.

For women, the iron in amaranth can help replenish stores lost during menstruation, supporting overall hormonal balance and energy levels. Its nutrient density makes it particularly valuable during hormonal transitions like puberty, pregnancy, and menopause.
