It’s not your imagination, brussels sprouts do taste better. How gene editing is changing how we grow and eat food (2024)

As a kid, I refused to eat vegetables. I still have memories of eating casseroles and picking out the tiny green peas for easier access to the yummy noodles.

As a health-conscious mom, I began to try all kinds of nutritious “superfoods” that I wouldn’t have touched as a picky kid.

The first time I tried brussels sprouts, I couldn’t believe how much I enjoyed them. I figured my taste preferences had changed with age, and I had grown to enjoy bitter flavors.

But it turns out, my tastebuds didn’t change. I recently discovered that brussels sprouts truly do taste better now than when I was a kid, thanks to science.

About 30 years ago, a Dutch scientist identified the chemicals that made brussels sprouts bitter. He selected seed varieties with lower levels of the bitter chemicals and bred new high-yielding varieties that tasted less bitter.

And better-tasting brussels sprouts are good, not only for our appetites but also because most of us aren’t eating enough vegetables. The Centers for Disease Control reports that 90% of Americans aren’t eating the daily recommended servings of fruits and vegetables.

We all could use a little motivation – including tastier vegetables - to eat healthier.

What are genetically engineered foods?

The new brussels sprouts varieties were developed through conventional plant breeding. In the near future, we can expect to see more gene edited foods, including foods developed through conventional breeding and through bioengineering.

Throughout history, farmers have bred plants for the best characteristics, like disease resistance and drought tolerance. The lengthy process of observing, selecting and breeding could take years or even decades to complete.

Today, scientists can use gene editing to make small, precise changes to improve plants and provide solutions to a variety of challenges. These changes often mirror what could occur in nature or through traditional genetic selection.

In the field of medicine, scientists are researching how gene editing can treat diseases such as cancer, leukemia, sickle cell anemia and a wide range of genetic disorders.

In agriculture, gene editing can help farmers keep pace with the growing demand for more and better food, while using less water, land, nutrients and other resources.

New gene-edited foods

This summer, the North Carolina-based company Pairwise debuted Conscious Greens, the first bioengineered food introduced in the U.S. developed by CRISPR gene-editing technology.

The Conscious Greens Purple Power Baby Greens Blend is now available in select restaurants and retail stores on the West Coast.

Like the new brussels sprouts, Conscious Greens has a less-bitter taste. The greens also have double the nutritional value of Romaine lettuce and a three-day longer shelf life.

Of course, no one likes the texture of wilted lettuce that has sat in the fridge too long. However, a longer shelf-life also benefits the environment. Food waste in landfills is a major contributor to greenhouse gas emissions, according to the Environmental Protection Agency.

In addition, genetic editing technology could give us tastier, more nutritious and more resilient sweet corn.

Iowa State University researchers are part of a federal study to boost the taste and texture of sweet corn.

The agronomy research also could help improve the genetic diversity of sweet corn, so the crop isn’t as susceptible to drought, disease and pest pressures in changing weather patterns.

Committed to nutrition and sustainability

Scientists, farmers and food producers are committed to doing what’s right for people, animals and the earth.

And farmers understand their obligation to meet the growing demand for healthy, wholesome food while also preserving our natural resources. Gene editing technology can help farmers achieve both.

As a parent and a wellness-minded shopper, I support any effort to take the yuck out of brussels sprouts, or to help plants and animals thrive.

After all, I want to feel confident that I’m providing my family with tasty, nutritious foods that can benefit our health while protecting the environment for my daughter’s generation and beyond.

FAQs

Did they genetically modify brussel sprouts to taste better? ›

He selected seed varieties with lower levels of the bitter chemicals and bred new high-yielding varieties that tasted less bitter. And better-tasting brussels sprouts are good, not only for our appetites but also because most of us aren't eating enough vegetables.

Is there a gene that makes Brussels sprouts taste bad? ›

"People with certain genetic variants in the TAS2R38 gene can detect bitter taste more than others and therefore may be more likely to dislike sprouts,” 23andMe senior product scientist Alisa Lehman recently told the Daily Record. "There are many factors outside genetics that play a part in the foods we like.

Did they change the taste of Brussels sprouts? ›

Soon, plants grown from the old seeds were cross-pollinated with modern, high-yielding varieties, but it took years for any perceptible changes to really take hold. "From then on, the taste was much better. It really improved," Sintenie said. As the flavor has improved, so have sales.

How did they make Brussels sprouts taste good? ›

In the late 1990s scientists identified specific chemicals, called glucosinolates, that made Brussels sprouts taste bitter. Plant breeders started growing old seeds, previously discarded for producing paltry harvests, to identify tastier versions with lower levels of these compounds.

Do brussel sprouts have a chemical taste? ›

The bitter taste of Brussels sprouts comes from compounds called glucosinolates and their degradation products, he explains. These bitter tasting compounds are an important part of the plant's defence mechanism against leaf-eating enemies, such as insects, nematodes, slugs, and herbivores, like pigeons and deer.

Do GMO foods taste better? ›

One of the common misconceptions about GE foods is that the process changes many of the traits of the food crop. Actually, the taste and other characteristics are determined by the variety of the crop that the gene is inserted into.

Are there side effects from brussel sprouts? ›

In addition to having a bitter flavor, raw Brussels sprouts may increase gas in some people. They contain an indigestible fiber called raffinose, which can be tough on the stomach.

Is it OK to eat smelly brussel sprouts? ›

Foul, moldy odor When your brussel sprouts are still fresh and good to eat, they won't have much of an odor or they may smell a little earthy. Brussel sprouts normally only smell after you cook them, so toss out any that have any strong odors while they're still raw.

Is it okay to eat Brussels sprouts raw? ›

It's hard to beat the caramelized crispness of roasted Brussels sprouts (perhaps with a maple-Dijon glaze), but these little green guys can also be eaten raw. They're delicious when shaved in a salad dressed with olive oil and lemon juice, to start.

How to remove bitterness from Brussels sprouts? ›

The sweetness works with the bitterness, and the sugar helps to caramelize the sprouts and bring out their own sweetness. A bit of brown sugar will also work. Acid can be useful as well. A splash of lemon juice, or even apple cider vinegar, works wonders on bitter sprouts.

Are Brussel sprouts natural? ›

As I said earlier, brussels sprouts are a human-engineered strain of a plant called Brassica oleracea, which is also known as wild cabbage. Other strains include broccoli, cabbage, cauliflower, kale, mustard greens, and turnips. Collectively, we refer to this family as cruciferous vegetables.

What is the gene for brussel sprouts taste? ›

This receptor is coded by a gene named TAS2R38, or the PTC gene. Even though PTC is not normally found in our food, it is very similar to chemicals found in cruciferous vegetables such as cabbage, broccoli, kale and Brussel sprouts. The PTC gene comes in 2 common forms – bitter-tasting or non-tasting.

Are Brussels sprouts good or bad for you? ›

Eating a lot of Brussels sprouts and other cruciferous veggies may help protect against cancers of the stomach, lungs, kidney, breast, bladder, and prostate. Crunchy veggies like Brussels sprouts may also help you stave off other health issues, such as high blood pressure, high cholesterol, heart disease, and diabetes.

Why do my Brussels sprouts taste weird? ›

Undercooked sprouts can taste even more bitter than the cooked variety. Overcook them, and they release more sulfur — which amplifies the cabbage smell.

Why aren't Brussels sprouts bitter anymore? ›

Over the last twenty years, farmers have mellowed the "unpleasant" flavor of brussels sprouts by breeding a vegetable that contains fewer bitter compounds or glucosinolates. So, brussels sprouts just taste better than they used to when we were kids. The rub is that glucosinolates help protect sprouts against pests.

Who made Brussels sprouts less bitter? ›

[In] the 1990s a Dutch scientist named Hans Van Doorn identified the chemicals that make Brussels sprouts bitter: sinigrin and progoitrin. After discovering this, the scientist worked to identify Brussels sprouts seeds and varieties with lower levels of these bitter chemicals.
