The soya bean traces its origin to China. In 2,853BC, Emperor Sheng-Nung of China named five sacred foods — soya bean, rice, wheat, barley and millet.

Between the 17th and 11th century BC, soya beans were cultivated in eastern China as a food crop. The first soya beans arrived in America in the early 1800s as ballast aboard a ship. It wasn’t until 1879 that farmers began to plant soya beans as fodder for livestock.

Soya beans are one of the crops being genetically modified. There has been a lot of controversy around these GMO (genetically modified) soya beans. Though these haven’t caused people harm, they could have a negative impact on the environment.

Soya beans belong to the legume family and have been an important source of protein for 5,000 years. Soya beans thrive in a variety of soils and a wide range of climates, ranging from tropical to snowy.

As the beans mature in the pod, they become hard and dry. Although most are yellow, there are also the black, brown and green varieties.

Benefits

The main health benefits are due to the protein content:

Improves bone health: Soya isoflavones help reduce the risk of osteoporosis. Soya beans can also indirectly improve bone health — in case of diets high in animal protein, a lot of calcium is lost through urine. Replacing animal protein with soya protein helps prevent calcium loss from bones.

Reduces menopausal symptoms: Menopausal symptoms are caused by low oestrogen levels. Through their oestrogen-like effect, soya isoflavones can control menopausal symptoms.

Reduces risk of heart disease: Soya beans reduce the cholesterol level and prevent plaque build-up in the arteries, which could lead to a stroke or a heart attack.
 
Prevents certain cancers: Regular intake of soya foods may help prevent hormone-related cancers such as breast cancer, prostate cancer and colon cancer.

Nutritional benefits: Soya products are rich in protein, which is of high quality because it contains all the essential amino acids.

Soya is also a good source of lecithin and vitamin E — natural antioxidants that prevent the oxidation of LDL cholesterol. Soya is also rich in magnesium, important in keeping bones, heart and arteries in good shape.

How to cook

Soya beans are generally taken in the form of other foods, such as tempeh, tofu, miso, shoyu and soya milk. But cooked soya beans are also used as an ingredient in soups, sauces and stews.

To prepare two cups of soya beans for cooking, soak them in six cups of water for eight hours. This shortens cooking time, improves the texture and appearance of the beans and removes some of the indigestible sugars the beans contain.

Drain, rinse and cook the soaked soya beans in six cups of water. Do not add salt at this point or it will delay the softening of the beans. Pressure-cook the soaked soya beans for about 40 minutes.

Storing

Fresh soya beans, or edamame, should be refrigerated and used within two days. Frozen edamame can be stored in the freezer for many months. Dried soya beans can be kept in an airtight container.

Soya bean and pasta

  • 300g rice pasta
  • 250g soya beans, frozen
  • 250g green beans, trimmed and halved
  • 1 tsp sesame oil
  • 1 tbs soya sauce
  • 1 small knob ginger, grated
  • Juice of 1 lime
  • 50g alfalfa
  • 2 carrots, grated

Boil the pasta, adding the soya beans and green beans three minutes before cooking is over. Drain, tip into a colander, then cool under running water.

Whisk the oil, soya sauce, ginger and lime juice in a large bowl; then tip in the pasta, cooked beans, sprouts, carrots and coriander. Toss; serve.

Soya bean and herb risotto

  • 2 tbs olive oil

Heat the oil in a large pan. Add the onion and fry over medium heat for 8 to 10 minutes until soft and lightly golden. Stir in the soya beans, sage, lemon zest and rice, then fry for another two to three minutes.

Simmer. Add the hot stock, a ladleful at a time, letting it be absorbed before adding more. Keep stirring and adding the stock until the rice is just cooked and all the stock has been used.

This will take about 18 to 20 minutes. Stir the cheese into the risotto and season. Pile the risotto into warm bowls and top with sage leaves.
