Health Benefits of Lupin Beans

 

Lupini beans, also called lupins, are the seeds of the lupinus plant. It is a very popular yellow legume seeds in Mediterranean regions and also in certain parts of America like Latin America. The plant is native to West Asia (Turkey, Palestine) and the eastern Mediterranean region of southern Europe (Balkans, Greece, Cyprus, Italy,). Other common names of the beans are bitter White Lupin, Broad-Leaved Lupin, Broadleaf Lupin, Egyptian Lupin, European White Lupin, Mediterranean White Lupin, White Lupin, White Lupine and Termis seeds.  These yellow legume seeds are a part of Lupinus genus. There are mainly 3 types of lupin beans. They are Lupinus albus, Lupinus mutabilis, and Lupinus hirsutus. They are leguminous seeds with high protein content.  They are traditionally eaten as a pickled snack food, primarily in the Mediterranean basin and Latin America.  These legumes contain high alkaloid content, making them very bitter and even toxic to eat without the proper preparation. However, if cooked correctly, they can be both nutritious and tasty. Lupini beans are sometimes eaten pickled as a snack. In Italy, they are considered a treat at Christmas.

Plant Description

Lupin beans is an annual, erect, branched, bushy more or less pubescent herbaceous plant that grows about 30 to 150 cm tall. It is found growing in disturbed sites and poor soils and occurs in meadows, pastures, and grassy slopes. The plant grows in organically rich, moderately fertile, slightly acidic, evenly moist, well-drained soils. Growth is delayed on heavy clays and waterlogged soils. Calcareous or alkaline soils cause chlorosis and reduce growth although some cultivars are more tolerant to soil salinity and heavy soils. Stipules are persistent, acicular, subulate, concrescent with the petioles over 1/3 of their length.

Leaves

Leaves are alternate, digitally compound with 5–9 leaflets. Leaflets are oblong or obovate, 2–6 cm by 0.5–2 cm, cuneate at base, rounded and mucronate at apex, glabrous above and villous below, margins ciliate.

Flower

Flowers are bisexual, zygomorphic, papilionaceous; pedicel 1–2 mm long; calyx 8–14 mm long, densely hairy outside, 5-lobed, tube 4 mm long, 2-lipped, upper lip entire, lower lip entire or slightly 3-toothed; corolla white to violet-blue, standard obovate, 15–18 mm × 8–12 mm, margins partly reflexed, wings obovate, 13–17 mm × 6–10 mm, keel ladle-shaped, 12–15 mm × 4 mm, beaked; stamens 10, monadelphous, united below; ovary superior, 1-celled, style c. 7.5 mm long with a ring of small hairs below the stigma. Flowering normally takes place from Jun to July.

Fruit

Fruit is a narrowly oblong, laterally compressed pod 6–15 cm × 1–2 cm, bulging over the seeds, shortly hairy but glabrescent, yellow, 3–6-seeded. Seeds are rectangular or square with rounded corners, laterally compressed, 7–16 mm × 6–12 mm× 2–5 mm, more or less smooth, seed surface mottled or patchy.

History

White lupin originates from West Asia (Turkey, Palestine) and the eastern Mediterranean region of southern Europe (Balkans, Greece, Cyprus, Italy,) where domestication occurred during ancient times and wild types are found. Today white lupin is a traditional minor pulse crop, grown around the Mediterranean and the Black Sea, and in the Nile valley, extending to Sudan and Ethiopia. It is also cultivated elsewhere, e.g. in Kenya, Tanzania, Zimbabwe, South Africa, Mauritius, United States and South America (mainly Brazil and Chile).

Health benefits of Lupin Beans

Lupini Beans are a legume that grow all over Europe and is a common snack food in Portugal, Spain, France, Italy, Greece, and Egypt. Lupini Beans are full of protein, fiber, and low in oil and starch and because of that weight loss is commonly related with eating Lupini Beans. They are full of the amino acid arginine which also helps lower blood pressure, lowers cholesterol & trigs, and lowers blood sugar levels. Lupini Beans also act as a pre-biotic therefore improving large bowel health. Listed below are some of the health benefits of consuming lupin beans

1. Prevention of Digestive Problems

Frequent consumption of Lupini beans promotes gut health and helps cope with constipation, irritable bowel syndrome, and other conditions related to the digestive system. High fiber content makes them good prebiotics, the substances that feed good bacteria in the intestine. Research has shown the direct link between these healthy bacteria and the state of the immune system.(1)

2. Lower high blood pressure or hypertension

An abnormality in the innermost lining of the blood vessels, kidney diseases, and excess sodium in the body is actually the main cause of hypertension. Lupin protein extracts have shown to correct the vascular endothelium dysfunction.

It helps in proper relaxation of the blood vessels, which assist in lowering the high blood pressure. Hypertension leads to heart attack, stroke, paralysis, eye impairment, etc. Now we are protected from all these complications of hypertension if we eat lupine beans regularly.(2)

3. Relieve constipation

High fiber content of lupin beans ensures that the stool in the gut absorbs water from the body and becomes soft. Dietary fiber helps in easy passage of stool through the gut. Relief from constipation prevents complications of constipation like anal fissure and hemorrhoids or piles. (3)

4. Make intestines healthy

In order to be energetic and have a good health, we need to have a good digestive system or intestine. We need to eat foods that promote the growth of helpful intestinal bacteria. These foods are called prebiotics and probiotics.

Lupini kernel fiber has shown to promote the growth of helpful intestinal bacteria like bifidobacteria. They also reduce the growth of harmful intestinal bacteria like Clostridium (Eg: Clostridium ramosum, C. spiroforme, and C. cochleatum).

5. Treat anemia

Lupini beans consist of good amount of iron which helps in the formation of hemoglobin. Vitamin C content of these beans also helps in promoting the absorption of iron and the formation of hemoglobin.

Anemia causes many problems like fatigue, shortness of breath, pallor of the skin, etc. Lupini beans help in treating anemia to some extent and help to relieve us from these symptoms.

6. Beneficial for skin

Antioxidant present in Lupini beans helps to fight the harmful free radicals. Free radicals can damage the skin and lead to premature aging. Free radicals lead to the development of age-related changes like age spots, wrinkles and fine lines at a young age.

Antioxidant content of lupine beans prevents early aging. It also reverses the signs of aging like wrinkles. Also, the vitamins and minerals in these beans nourish the skin and make it healthy and glowing.

7. Boost immunity

Healthy immune system is quite important to fight all the infections. We need to take a good diet rich in vitamins and minerals to strengthen our immune system.

Lupini beans contain all the essential minerals and vitamins like vitamin A, B complex, vitamin C which make our immune system strong. Vitamin C content of lupin beans also makes our immune system strong and capable of fighting infections like colds and flu.

8. Beneficial for hair

Our hair is made of proteins. So, high proteins content of lupin beans helps in the formation of healthy hair structure. The high protein content of these beans also makes the hair strong, thick and difficult to break or fall down.

Apart from that our hair also requires sufficient amount of vitamins and minerals for healthy growth. Lupin beans have all the required nutrients to promote healthy hair growth.

9. Help in weight loss

As mentioned before lupin beans consists of higher fiber content that make a person remain satisfied for a longer period of time. As a result, people who consume lupin beans consume lesser quantity of other foods in their meals.

This resulted in significant weight loss among these people. Also, there has been a reduction in the waist circumference and body mass index or BMI as per the study.

10. Protects the heart

Our heart can suffer from several illnesses like atherosclerosis, heart attack or myocardial infarction and heart failure. High blood pressure, high blood sugar levels or diabetes, high cholesterol levels or hypercholesterolemia are the main culprits behind the development of heart diseases.

According to a research on animal subjects, lupin protein extracts have shown to reduce the development of atherosclerotic lesions. They also reduce the high blood sugar, high blood pressure and high cholesterol levels which are the risk factors for heart diseases.

11. Strengthen bones

Maintaining the health of bones is very important to avoid suffering from problems like osteoporosis, fractures, etc. Calcium and phosphorus present abundantly in lupin beans are essential to make the bones strong and healthy. They work together and make our bones and teeth healthy. About 85% of phosphorus is present in our bones and teeth.

Selection

Look for lupin beans with other canned beans / legumes in a well-stocked supermarket.

You may find them pickled, in a jar or vacuum sealed bag, and ready to eat.

As noted, it’s best to be aware of the sodium content when buying canned lupin beans. Because lupin beans may be soaked in a salt-water solution to rid them of bitterness, they do retain quite a bit of sodium. When choosing canned lupin beans, check sodium content on the can first.

Storage

As usual with canned beans, use before the expiration date. If using dried beans, store them in a cool, dark place. Make sure they are properly marked so they do not get confused with another type of bean, since lupin beans are toxic if not cooked correctly.

Once a can is opened or lupin beans are soaked and prepared, they will keep in the fridge for up to 5 days.

Preparation

If using canned lupin beans, carefully rinse the beans before eating. (While this is a good tip for all canned beans, it is especially important with lupin beans, given their high salt content. You won’t be able to rinse away all the salt but you may be able to reduce it by close to half the amount.)

If using dried beans, you will need to pre-soak them. Recipes for soaking differ: some suggest soaking in water for two weeks, others suggest a salt-water solution for one to two weeks, and still others recommend boiling the beans before the soaking process.

The simplest method is to soak the beans in cold water, changing the water daily, for at least a week. Over time, the alkaloids will dissolve into the water and the beans will become softer and less bitter. How long you soak the beans will depend on your personal preference: the longer they soak the less bitter and firm they will be.

Once finished soaking, you can eat the beans raw, but they will be quite firm. Most people prefer to cook the beans. One tasty method is to slow cook them with garlic and olive oil. You may also try marinating them in spices, herbs and olive oil, or pickling them.

The prepared beans can be added to salads or enjoyed on their own as a side dish or snack.

You can eat the beans with the skin on, but if you prefer a softer texture, tear the tough skin lightly with your teeth, and pop the inner bean into your mouth.
