Jackfruit, lend me your genes

The ABCs of Biotech for Christians - Eleventh in a series - J is for Jackfruit

Biotech has disappointed some people by engineering changes in crops, animals and vegetation, but it has impressed us with insights about food that guide us to eat intelligently. We are what we eat!

The jackfruit grows in the tropical zone and is commonly found in the land and markets of India, Sri Lanka, Bangladesh, parts of Africa, Brazil, the Philippines, and other areas of year-round humid, warm climate. According to the California Rare Fruit website some Jackfruit trees are in southern Florida but they are for sightseeing rather a food source. Some fruit may be found in ethnic markets in the US.

You can learn a lot about jackfruit and recipes for it on YouTube videos or websites. Its benefits are very well delineated here. From a wrinkle treatment to promoting hair growth to fortifying your immune system to healing ulcers, it is an incredible food.

And it has the distinction of being the largest tree-borne fruit in the world. One can weigh as much as 100 pounds and grow to 36 inches in length and 20 inches in diameter! You could order one on Amazon for about $90, expensive no doubt because of its weight and shipping. So, most who eat it live in parts of the world that have many poor people, and it is God’s gift to them with 10 or 12 pods providing one-half day of food.


Jackfruit is among the foods that offer prebiotic help for “gut” health. An article on ScienceDirect.com describes a biotech goal of taking the prebiotic elements from certain foods to introduce them into others through genetic modification to give them the prebiotic “edge”:

Prebiotics are non-digestible complex carbohydrates that are fermented in the colon, yielding energy and short chain fatty acids, and selectively promote the growth of Bifidobacteria and Lactobacillae in the gastro-intestinal tract. Fructans and inulin are the best-characterized plant prebiotics…
Transgenic maize, potato and sugarcane with high fructan, with no adverse effects on plant development, have been bred, which suggests that it is feasible to introduce fructan biosynthesis pathways in crops to produce health-imparting prebiotics.
Developing prebiotic-rich and super nutritious crops will alleviate the widespread malnutrition and promote human health…

This excerpt explains to us that biotechnology is working on genetically engineering certain crops with the genes of prebiotic plants so that they too can provide prebiotic benefits. The jackfruit is one potential source of prebiotic carbohydrates.

Maize, potato and sugarcane are foods or sugar eaten in quantity by obese and overweight people, who have been discovered to have a different gut microbiotic profile than lean people. So, by modifying those crops to have a prebiotic profile, one with complex carbs that are not digested but rather promote good bacteria in the gut, overeaters will enjoy better health.

But maybe some foods are not meant to be prebiotic. ?

...and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind ... the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind ...the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind: and God saw that it was good. -Genesis 1


A SistersSite eBook

Flesh and Bone and The Protestant Conscience is an e-book on Amazon.com. It is 99¢ and in the Amazon lending library as well. It is also available here in PDF format. The book description follows.

Would you let your conscience be your guide?

Does God care if the skin and bone of the dead are passed along to the living for medical uses? Is organ donation OK with God? Should you sign a Living Will?

Did you know that dead organ donors are often anesthetized before their organs are removed? Do you know the current definition of death? The conscience cannot function without facts.

As we ponder the ethics of in vitro fertilization, stem cell research and man-made chimeras, our thoughts trail off. How then should we live? (Ez 33:10)

How should a Christian think about euthanasia by starvation when doctors and the state attorney general all agree it is time to withhold feeding from a brain injured patient? Some things are family matters, but someday it may be our family.

Here is a small book to help you think about whether you want to sign your driver's license, donate a kidney, cremate your loved one, and many other practical questions that may arise in the course of your healthcare decisions or watch over others.

It offers a special focus on the doctrine of the Resurrection that is related to such decisions. Sunday School classes and Bible Study groups could use this book to facilitate discussion about the issues covered.
