kiwicha

What is kiwicha?

Kiwicha is a tiny Andean grain eaten as food. It comes from the plant Amaranthus caudatus, one of the amaranths. Cooks use it much like quinoa, rice or oats.

It is not a true cereal. Botanists call it a pseudocereal, which just means a seed used like grain. It contains no gluten, the protein found in wheat, barley and rye.

The seeds are rich in protein, fibre and minerals. The young leaves are also eaten as a green vegetable. Some shops sell amaranth seed oil or flour as a supplement.

Here is the honest verdict. Kiwicha is a sound, nourishing food with a very long record in the Andes. As a treatment for high cholesterol or high blood sugar, the human evidence is small, mixed and far from settled.

Long use in a tradition is not proof that something works. It is also not proof that it is safe. This page says once what is known and once what is not.

How does kiwicha work?

Most of what kiwicha does is simply what good food does. It supplies protein, fibre, iron, magnesium and calcium. That part is not in doubt.

Its protein is unusually rich in lysine, an amino acid that most grains lack. This makes it a useful protein source in plant-based diets. That nutritional point is well established.

The grain also holds squalene and plant sterols, which are fat-like compounds. In animal studies, amaranth oil and these compounds lowered blood fats. Whether this happens in people at normal food amounts is not established.

Soluble fibre may slow how fast sugar enters the blood after a meal. Small human studies hint at a modest effect. The results are not consistent, and the trials are short.

In laboratory tests, peptides made from amaranth protein block an enzyme linked to blood pressure. This is test-tube work only. It does not show that eating kiwicha lowers blood pressure.

What forms does kiwicha come in?

Kiwicha is sold mainly as a food, not a pill.

- Whole dry grain, boiled into porridge or added to soups - Popped or puffed grain, used in cereal and snack bars - Flour, blended into bread, pancakes and gluten-free baking - Flakes, used like oat flakes - Fresh leaves, cooked as a green vegetable - Amaranth seed oil, sold in bottles or capsules - Protein powders that list amaranth among the sources

The popped grain mixed with syrup is a classic sweet in Peru, Bolivia and Mexico. In Mexico these bars are called alegrías. Labels may say amaranth, kiwicha or kiwikicha; they refer to the same plant group.

Where it comes from:

Kiwicha fed the Andes for thousands of years. Archaeologists have found amaranth seeds in Andean sites dating back several millennia. It was a staple grain alongside quinoa, maize and potatoes.

The Inca grew it widely before the Spanish conquest. Amaranth also had a ritual role in Mesoamerica, where seeds were mixed with syrup and shaped into figures. Spanish authorities discouraged the crop, and planting shrank sharply.

Andean households kept growing it in small plots. Traditional healers and mothers gave the cooked grain to children, nursing mothers and people recovering from illness. Leaf poultices were applied to the skin in some areas.

From the 1970s onward, agronomists promoted kiwicha again as a hardy, protein-rich crop. It is now exported widely as a health food. These are records of past practice, not advice to treat yourself with it.

What does kiwicha help with?

• General nourishment and protein in plant-based diets: This is the clearest use, and it is a food use. Kiwicha supplies good protein with plenty of lysine, an amino acid most grains lack. That makes it a helpful partner to beans, rice and maize. Food composition data support this plainly. It is nutrition, not treatment.
• Gluten-free eating for coeliac disease: Kiwicha contains no gluten, so it suits coeliac disease (a gut illness triggered by gluten). Studies of coeliac diets list it among safe grains. The catch is cross-contamination. Grain handled near wheat can pick up gluten. Buy packs tested and labelled gluten-free.
• Feeding children and people recovering from illness: Andean tradition gave cooked kiwicha to children, new mothers and people getting over illness. It is dense in protein and minerals, which fits that use. A few small feeding studies in children found it a useful addition to the diet. It is not a treatment for malnutrition on its own. Serious weight loss or poor growth needs medical care.
• High cholesterol (unproven in people): Tradition did not claim this; modern marketing does. In animal studies, amaranth oil and squalene lowered blood fats. Human trials are few, small and mixed. Some showed small drops in LDL (the harmful cholesterol), others showed none. Do not drop a prescribed statin for it.
• Blood sugar control (unproven in people): Fibre-rich whole grains are linked with steadier blood sugar in general. Some small studies of amaranth meals showed a smaller sugar rise after eating. The trials are short and few. Nothing here shows it treats type 2 diabetes. It may fit a diabetes diet as a whole grain, which is different.
• Constipation and low fibre intake: Kiwicha is a good fibre source, and fibre helps keep stools soft and regular. That effect of fibre as a whole is well established. No trial has tested kiwicha itself for constipation. Treat it as one more fibre-rich food, not a laxative.
• Low iron intake: The grain is relatively high in iron, which matters in diets with little meat. But phytic acid in the seed cuts how much iron you absorb. Soaking, sprouting and cooking reduce that effect. Vitamin C in the same meal helps absorption. Kiwicha alone will not correct diagnosed iron deficiency anaemia (low iron in the blood).

Which foods are rich in kiwicha?

1. Boiled kiwicha porridge
2. Popped or puffed amaranth
3. Alegría bars (popped amaranth with honey or syrup)
4. Amaranth flour breads and pancakes
5. Gluten-free pasta made with amaranth
6. Cooked amaranth leaves, eaten as a green vegetable
7. Andean soups and stews thickened with the grain

Practical Tips:

Kiwicha is easiest to get as plain food. Whole grain, flour and popped amaranth are sold in supermarkets and Latin American shops.

Cook the grain in water or milk until soft, as you would porridge. Popped amaranth needs no cooking and suits snacks and toppings.

One point of confusion is worth clearing up. The red food dye called amaranth (E123) is a synthetic colour. It has nothing to do with this plant.

What are the side effects of kiwicha?

• Bloating and wind, especially when you add a lot of fibre quickly
• Loose stools or stomach cramps
• Reduced absorption of iron and zinc from the same meal, due to phytic acid
• Higher oxalate intake from the leaves, which matters for stone formers
• Rare allergic reaction, with rash, itching or swelling
• Rare hay-fever-type symptoms from amaranth pollen in people who grow it

Good to know:

Side effects are mild and uncommon. Most people eat kiwicha with no trouble at all.

The usual complaint is gas or loose stools when fibre jumps suddenly. Raising the amount slowly over a week or two usually settles it.

True allergy to amaranth is rare but has been reported. Stop eating it and get medical help if you get swelling, hives or trouble breathing.

How much kiwicha should you take?

• Recommended daily: Kiwicha is a food, so there is no set dose. A typical cooked serving starts from about 40 to 60 grams of dry grain, which is what recipes and packs tend to suggest. Amaranth seed oil products usually carry label amounts of a teaspoon or two a day. Those are label figures, not advice for you. If you have diabetes, kidney stones or coeliac disease, talk to your doctor or dietitian about how it fits your diet.
• Best time of day: Timing does not matter much. Porridge at breakfast and grain at dinner are both common. If you take iron or zinc tablets, it is sensible to space them a couple of hours from large fibre-rich meals.
• With or without food: It is food, so it is eaten as part of meals. Cook the grain or buy it popped. Do not eat the raw dry seed in quantity. Raw amaranth is hard to digest and holds more saponins and phytic acid.
• Time to effect: As food, it nourishes you from the first meal. There is no waiting period for that. For cholesterol or blood sugar, any change would take weeks of regular eating. It may also do nothing at all. The human evidence is too thin to promise a result.
• How long to take it: As a grain, it can stay in the diet long term, like rice or oats. Andean households have eaten it daily for generations. Concentrated oils and supplements are different. Trials of them ran weeks to a few months, so longer safety is not well studied.
