What is edamame?

The harvesting of young soybeans, before they ripen or become hard is termed as Edamame.  These healthy edibles are available shelled, frozen, pod or fresh. They appear green and have a noticeable difference in color when compared to soybean. Soy is, without doubt, a natural source of many essential nutrients. It adds flavor and balances health in a complete meal plan. Soy is present in, soymilk, soy burgers, Edamame, tofu, and soybeans.

edamame beansEdamame is also called as “immature soybean” as they are green, soft and easily edible. The very name Edamame was derived from a Japanese name, meaning “beans on branches”.  Edamame found a place in the food chain when it was first used by a Buddhist saint, Nichiren Shonin. He mentioned Edamame in his book titled, “Nichiren Shonis Gosho Zenshu” which translates into, “The Collected writings of Saint Nichiren”. It is mandatory that they are consumed when they are green because they become inedible when they change to brown or yellow. Edamame is classified as vegetables as they belong to the soy family.

The origins

Before the world got to know about it, Saint Nichiren Shonin wrote a thanking letter to his friend for sending him Edamame, in the year 1275 AD. Long before it could find a place in the biological nomenclature, the Japanese were found surviving on it during the famine. Its health benefits were later discovered and it went on to be served as a pre-cooked meal, and a healthy snack.

It was during 1855 that Edamame found its entrance into the United States of America when a farmer found difficulty in harvesting his soybeans. The word Edamame paved its way into the English dictionary in the year 1951, when it was mentioned in the journal “Folk Studies”. It was then appeared as a new terminology in the Oxford dictionary in the year 2003 and later was added to the Merriam-Webster in 2008.

Edamame harvest

The harvesting of the Edamame is done by hand, to avoid damaging the crops. The pods are grazed from the soybeans and carefully planted. It is essential to pick the soybeans exactly 35 to 40 days from the day it starts flowering. The soybeans are picked even while they are ripe and still remain in the pod. It is mandatory to cross-check the color of the Edamame, as only bright green color soybeans can make a fine Edamame. Edamame is sweet as it contains high levels of sucrose during its harvesting phase. The harvested Edamame is processed further by boiling, steaming or microwaving. The Edamame can be freshly eaten or can even be prepared as a dish with essence of varied flavors.

Edamame: What do health experts have to say

edamame brainThe growth in food allergies and tolerances has seen a rapid increase. With this being the scenario it is mandatory to cross-check allergic reactions for soybeans, Edamame or any soy products. It triggers allergic reactions in children affected by eosinophilic esophagitis (an allergic inflammatory condition that involves eosinophils, a form of white blood cell).

With insufficient studies to prove its benefits there are varied factors that make it difficult to structuralize a specific statement relating to the effects that Edamame causes. This is because most of the experimentation on Edamame was carried out on animals; it is, therefore, difficult to jump to a conclusion as the metabolism in animals and humans differ.

At present, the production of Edamame is prone to genetic modification and can result in the consumption of adulterated Edamame. It is therefore essential to consume organic Edamame which is safer and loaded with substantial nutrients that help maintain our body both physically and mentally. A kick start to being healthy depends on the nutritional ingredients that you put on your plate.

Maintaining your nutritional balance with the necessary amount of Edamame can result in a healthy venture for a better morrow and contribute to maintaining optimal health by avoiding certain chronic ailments. As Hippocrates said, “Let food be thy medicine and medicine be thy food”.
