Yacon – Scientific name: Polymnia sanchifolia

Advertisements

English: Yacon
Tagalog: Yakon

There is now a new root crop that goes by the unusual name yacon. Recognized as a health food, it is also known as the apple of the earth because although it is grown underground like any other root crop, its fruit resembles an apple or a pear. Also, unlike regular root crops whose carbohydrate content eventually turns to starch, then sugar, when ingested, the yacon stores carbohydrates in the form of inulin and not starch. High in inulin, it serves as a sucrose-free food for diabetics.

The yacon is also low in calories, thus making it a good, nutritious diet food. While a sweet potato contains 125 calories, a potato 77 calories and a taro 60 calories per 100grams, the yacon has only 54 calories. It contains carbohydrates (oligo-fuctans),which pass through the digestive tract unmetabolized, so that it is perfect for those who suffer from obesity. Add to this the fact that the yacon purifies the blood and whose high-fiber content assists in digestion.

ORIGINS…

The yacon is believed to be a lost crop of the Incas. A little known plant of the Andes, it grows wild in Colombia, Ecuador and Peru. It also grows at medium altitudes in South America. In the warm, temperate Andian Valleys, it can be found at altitudes up to 3,200 meters. It can be cultivated worldwide, and in the Philippines, it is grown 100% organically.

The absence of harmful chemicals and insecticides makes it even healthier. A herbaceous plant with dark green celery like leaves, it has hairy aerial stems that reach up to 2 meters in height as well as small, daisy-like yellow or orange flowers that a repacked close together at the top of the plants. Yacon tubers are irregularly spindle to round and can vary considerably in shape, size and sweetness.

NUTRITIOUS FOOD

The yacon, which is a member of the sunflower family, is grown primarily for its edible roots. While it looks like sweet potatoes or yam on the outside with its brownish, sandy skin, inside, the yacon looks more like a juicy fruit such as the apple and the pear. Just peel off the skin, wash it, slice it up into pieces, and eat it raw. It feels just like a pear or an apple to the bite, with a crunch accompanying small bursts of juice.

The yacon can also be boiled or sauteed in oil. Having all the characteristics of a health food that aids in the maintenance of good health, the yacon contains potassium, magnesium, calcium, Vitamins A, B1, B2 and C, phosphorus, niacin, iron, carotene, protein, lipids, cellulose, glucide and fiber.

MEDICINAL VALUES

More than just being a valuable health food, the yacon has also been discovered to have medicinal values. The tuber can be used as medicine. Simply preserve it for 10 days so that it reaches its full level of sweetness, and then peel it, slice into thin cuts and eat it raw. Its leaves also have medicinal properties. Do the leaves naturally in the shade, then cut into suitable sizes and boil in water to make a cleansing tea. The recommended daily intake of the yacon tea is 2 cups daily. Because the inulin content of the yacon is 60 to 70%, it helps control the blood glucose and keep it at a normal level. So those who are eating the tuber will notice initial results within 7 to 10 days, while those who drink its tea can expect initial health benefits in as short as 4 to 5 days. Above all else, the yacon is delicious!

    i want to buy yakon or yacon tablet.i heard its good for diabetic people.i also want other herbal medicine for diabetis & also for prostate problem

    I am eating Yacon now. I started intake 4 days ago because somebody told me it reduces high blood pressure. I have no question about it’s taste because I find it sweet and delicious like pear or apple. There is no question either of price because I can buy it cheap from our supplier (who bought it from Davao – 12 hours ride by bus to our place in Surigao del Sur).

    My questions are:

    1) Can this root crop be safe for paralytics like me? Of course, I have tendency to have high blood pressure though I have maintained my blood pressure to normal.
    2) If safe, how much intake could I be allowed to eat a day?
    3) Aside from diabetes, what other sicknesses would benefit from this root crop?
    4) Are there known side effects? If there are, kindly inform us (my friends and I), sir.
    5) Like any other root crops that we can plant using the “root” tubers, can I also plant it in my backyard so that I won’t have to buy anymore? Aside from this, I could also enjoy the benefit of the lives for tea. If so, please tell us how to do it.

    Thank you very much for taking time to read this comment.

    Sincerely,
    Luisa

    yes it is safe, It is safe to eat, just remember in everything moderation is the rule, everything in excess is not good. Aside from diabetics, indigestion or constipation may be relieved, hemorrhoidal diseases may also adress as well because it is high in fiber. Medically speaking, if your diabetes will be controlled, hypertension also will be controlled, incidence of stroke or cerebral bleed will also decrease.God bless us all

    hello everyone! hope you can help me with this as soon as possible.

    There is a project given by our teacher in entrepreneurship and it’s about making new products for spread (“palaman” in tagalog). Then I proposed YACON SPREAD but then she disapproved it. According to her, there was a time when some people were hospitalized due to yacon. But when I read articles and researches on yacon, there were no bad side effects I’ve seen. I am really disappointed with what she said because I’m thinking that yacon as spread is really a good idea..

    So this is my query: can you help me prove her there are no bad effects of eating yacon? Or can you give me some advices regarding this.. Thanks! I’m looking forward for any reply. ­čÖé

    Hanggang ngayon hindi pa nasasagot ang tanong ko.

    Hindi ba ito makasama sa goiter ko? Almost 2 weeks na ako kumakain ng yacon. Pls. repl my question.

    @Minda
    Hindi naman po siguro kasi wala namang sulphur content ang yacon at kung meron man ay konti lang siguro. Ang sulphur kasi ang nag-ba-block sa iodine intake natin. Kumain din kayo ng mga pagkain na mayaman sa iodine at gumamit ng iodized salt.

    Yes, yacon is very good for those who have arthritis. My cousin told me about it because he had a worker who could not walk because of his gout, he was given yacon and was able to walk back again just after two days. I have high blood sugar and is fighting it with healthy diet and exercise, I take Yacon, ampalaya and guyabano…but amongst all yacon is the yummiest. I simply get it from the grocery…SM hypermart has it.
