Yes, with important considerations
Yes, you can eat young, tender amaranth leaves raw, and many cultures have incorporated them into their cuisine this way. In fact, some varieties like young redroot pigweed are specifically mentioned as being safe for raw consumption in salads and smoothies. However, as with other foods that contain antinutrients, moderation is key.
Unlike amaranth seeds, which are generally not digestible raw, the leaves are less of a concern, but still require careful handling. Mature amaranth leaves, particularly those of wild varieties, can become more fibrous and develop a bitter taste, making them less palatable for raw preparations. For the safest and most nutritionally beneficial consumption, a better understanding of the plant's compounds is necessary.
Understanding the risks of raw amaranth
While amaranth leaves are generally safe when consumed in moderation, especially when young, they contain certain antinutrients that can pose risks, especially if eaten in large quantities. These compounds are the primary reason many sources recommend cooking the leaves.
Oxalates and mineral absorption
Amaranth leaves are naturally rich in oxalates, also known as oxalic acid. The oxalate content is significantly higher in some species compared to others. When consumed, oxalates can bind with minerals like calcium and iron in the body, which can inhibit their absorption. For most healthy individuals, this isn't a major concern with a balanced diet, but for people with a history of kidney stones or kidney problems, a high intake of oxalate-rich foods could be problematic. Cooking the leaves dramatically reduces their oxalate content, making the minerals more bioavailable.
Nitrates and overall safety
In addition to oxalates, raw amaranth leaves can contain nitrates. While present in many vegetables, the level in raw amaranth can be irritating to some sensitive individuals. Similar to oxalates, cooking the leaves helps to eliminate a large portion of these nitrates, further enhancing the food's safety profile.
The benefits of cooked vs. raw amaranth
| Feature | Raw Amaranth Leaves | Cooked Amaranth Leaves | 
|---|---|---|
| Nutrient Content | Higher levels of heat-sensitive vitamins like Vitamin C. | Reduced Vitamin C, but improved bioavailability of minerals like iron and calcium due to lower antinutrient content. | 
| Digestibility | Potential for digestive discomfort (bloating, gas) due to high fiber and antinutrient content, especially in larger quantities. | Easier to digest, with a softer texture. | 
| Oxalate Content | Higher levels of oxalates, which can interfere with mineral absorption. | Significantly reduced oxalate content through boiling or sautéing. | 
| Flavor Profile | Slightly astringent and nutty, potentially becoming more bitter with maturity. | Milder, more mellow flavor, similar to spinach. | 
| Best Uses | Small, tender leaves in salads or smoothies. | Sautéed side dishes, stews, soups, and curries. | 
How to safely prepare amaranth leaves
For those who prefer a cooked preparation, the process is straightforward and helps to minimize potential health risks associated with antinutrients.
To prepare cooked amaranth:
- Wash thoroughly: Just like any leafy green, wash the leaves thoroughly under running water to remove any dirt or residue.
- Trim if needed: While young stems are edible, tougher, older parts should be removed. Some prefer to trim at the point where the leaves begin.
- Boil and drain: A common method is to briefly boil the leaves (2-4 minutes) and then drain and rinse them in cold water. This significantly reduces oxalate levels.
- Sauté: Sautéing is another popular method. After washing, simply sauté the leaves with ingredients like onions and garlic until wilted.
- Add to dishes: Cooked amaranth can be added to soups, stews, curries, and rice dishes.
For those who insist on raw consumption, here are a few tips:
- Only consume very young, tender leaves. Mature leaves are more fibrous and bitter.
- Use a small amount. Don't overdo it in a single sitting.
- Always practice moderation, especially if you are new to the green.
- If you have a history of kidney stones or other related health issues, it is best to avoid raw consumption entirely and stick to cooked preparations.
Amaranth varieties and their uses
The genus Amaranthus includes over 70 species, and while many are edible, some are more commonly cultivated for their leaves or seeds.
Green amaranth
Often called Chinese spinach, varieties like Amaranthus dubius are widely used in Asian and African cuisine. Young leaves are mild and tender, while mature leaves can be slightly fibrous. Cooking helps to bring out a mellow flavor that is similar to spinach but with a slightly deeper taste.
Red amaranth
Known for its striking reddish-purple leaves and stems, red amaranth (Amaranthus cruentus) is both an edible and ornamental plant. When cooked, it can impart a pleasant pinkish tint to dishes like soups and tomato sauces. Young red amaranth leaves can be used raw, but like its green counterpart, cooking is recommended to reduce antinutrients.
Pigweed amaranth
Some wild varieties, often referred to as 'pigweeds', are also edible. For example, redroot pigweed is mentioned as a plant where young leaves can be added to salads and smoothies. However, because it's a weed, harvesting should be done with care, ensuring it's from a clean, unsprayed area.
Conclusion: Informed consumption is best
Ultimately, the decision of whether to eat amaranth leaves raw depends on individual preference and health considerations. While young, tender leaves can be safely consumed raw in moderation, the presence of antinutrients like oxalates and nitrates means cooking is the safer and more nutritionally efficient choice for most people. Cooking not only reduces these compounds but also enhances nutrient bioavailability, particularly for minerals like calcium and iron. By understanding the risks and benefits, and choosing the right preparation method for your needs, you can enjoy this versatile and nutritious green in a safe and delicious way.
