Broccoli is a very popular vegetable that has been around for over 500 years. It’s considered to be one of the most important vegetables in our diets, and it helps keep us healthy. The question we want to answer here is whether or not broccoli is genetically modified (GM).
Where Does Broccoli Come From?
The original source of the Broccoli plant was China, where it grew wild. In 1868, Dr. William Shasta discovered the first broccoli plants growing in California. The plant got its name because it had green flower buds resembling broccoli florets. Today, there are hundreds of different types of broccoli, including purple, orange, white and black varieties. These colors are determined by their genetic makeup.
In 1989, scientists at Plant Genetic Resources Unit created an intergeneric cross between Brassica oleracea (the cabbage family) and B. rapa (which includes turnips, collard greens and broccolis), creating what they called “broccolini.” They found that these new hybrids were more resistant than either parent species to certain herbivores like aphids and caterpillars. This led them to create the World Broccoflower Project, which produced new broccolis with even better pest-resistance qualities.
Since then, many other GM foods have been introduced into the food supply, such as potatoes [Source: BBC News]. So now you’re wondering if this means that all broccoli is genetically modified. Let’s find out!
Is Broccoli Genetically Modified?
No. There are no GMOs in broccoli.
This may seem hard to believe, but the reason why is because of how genes work. When a scientist says something is genetically modified, he or she really means that the DNA in the organism has undergone some sort of change due to genetic engineering. For example, when scientists insert a gene from another organism into an egg cell, they get a GMO. But that doesn’t mean that every part of the resulting organism is genetically modified.
For instance, let’s say someone wanted to grow a tomato that would produce flowers instead of fruits. If they used traditional breeding techniques, they could take a tomato plant and cut off the stem just below the fruit so that only leaves remained. Then they could fertilize those stems with pollen from a flowering tomato plant and hope that seeds would form. Afterward, those flowers might start to develop into tomatoes. And voila — you’ve grown your own beautiful pink cherry tomato flowers!
Now, let’s suppose that person decided to go ahead and take a cutting from the stem above the flowers and put it under his desk lamp. He’d continue to fertilize the stem with pollen from a normal tomato plant, hoping that some seedlings would sprout. Instead of cherry tomatoes, however, you’d end up with regular old tomatoes. You didn’t do any genetic engineering on the stem itself – you simply took a cutting from a non-modified plant. That means that the flowers weren’t genetically modified; neither were the tomatoes.
So if you see a picture of broccoli labeled “genetically modified,” don’t panic. Just know that the broccoli you eat hasn’t been altered via genetic engineering.
But wait… isn’t broccoli a hybrid anyway? Isn’t that genetic modification too? Not necessarily. A hybrid is exactly what it sounds like – a cross between two separate organisms. But a true GMO is an organism whose DNA was changed through genetic engineering. As previously mentioned, inserting a gene from one organism into an egg cell produces a GMO, but that doesn’t make every single organism in the offspring genetically modified.
There are also cases where people can breed plants without altering their genetics. One way is to use tissue culture propagation, which involves taking cells from a plant and using chemicals to divide them into millions of clones. Another method is grafting, which involves attaching branches from one plant to another. With both methods, the plants aren’t affected by changes in their environment. Because of this, scientists sometimes refer to tissue culture propagated plants as “Clonals” and grafted plants as “grafts.”
Another thing to note is that while scientists often talk about crossing species, technically they’re talking about interbreeding. Interbreeding usually requires a lab setting, whereas crossing species happens naturally.
Is Broccoli Man made?
Absolutely not. Broccoli is definitely natural.
Some people think that anything produced in laboratories must therefore be unnatural because science is involved, but that’s not always true. We’ve already discussed how scientists can alter genomes without affecting organisms via cloning or grafting. Other ways include changing environmental conditions, rather than altering the organisms themselves. Take yeast, for example. Yeast reproduce sexually, meaning that each daughter cell receives half of her parents’ chromosomes. Scientists can also manipulate yeast by introducing foreign genes into the genome. Since yeast are eukaryotes, they contain lots of complex structures like mitochondria, ribosomes and chloroplasts. By manipulating these parts, they can control yeast growth and behavior, making them useful tools for research. However, since yeast cells still follow sexual reproduction, they’re not genetically modified.
What Are the Health Benefits of Broccoli?
Broccoli contains high amounts of fiber, vitamin C, K and folate, and low amounts of fat. Eating broccoli will help fight cancer, heart disease, diabetes and obesity. Researchers are studying whether consuming broccoli may prevent birth defects and osteoporosis.
What are the Uses of Broccoli?
Most people probably know that broccoli is best eaten cooked, Boiled broccoli makes a great side dish. Steamed broccoli tastes delicious when prepared with butter, salt and pepper. Toasted bread crumbs and Parmesan cheese are good toppings for steamed broccoli. Sauteed broccoli is tasty when paired with brown sugar and soy sauce.
You can also try roasting broccoli in olive oil until tender. Or you can sauté it in a little bit of water with garlic and onions. Roasting brings out the flavor of broccoli, giving it a distinct taste. Sautéing gives the vegetable an extra kick. Finally, you can boil broccoli in salted water to give it a unique texture. Although boiling can soften the fibers, it allows the nutrients within to retain their antioxidant properties.
