Yes, cauliflower is considered a "clean" vegetable because it consistently ranks on the Environmental Working Group (EWG)'s 'Clean Fifteen' list, meaning it has low pesticide residues when conventionally grown, making it a good choice for those looking to minimize pesticide intake without always buying organic. It's a low-pesticide produce item, often appearing with items like avocados, pineapples, and onions.
(Same for the accompanying “Clean 15” list of produce with the lowest pesticide levels.) This year, EWG adjusted its methods to consider the toxicity of the substances. Under this methodology, blackberries and potatoes joined the 2025 Dirty Dozen list, while cauliflower and bananas were new additions to the Clean 15.
Gas and bloating: cauliflower is high in raffinose and fiber; fermentation by gut bacteria produces gas, causing bloating, flatus, cramping. Diarrhea or loose stools: excessive insoluble fiber can accelerate transit and irritate the gut, especially if intake jumps suddenly.
With very low or no discernible pesticide residue, conventionally-grown cauliflower is safe to buy. Low in fat and carbohydrates, cauliflower is high in dietary fiber, folate, potassium and vitamin C. This cousin of broccoli also contains glucosinolates, sulfur-containing compounds that help the body detoxify.
When it comes to nutrition, cauliflower is a superstar. It's high in vitamins C and K, and is also a good source of folate, which supports cell growth and is essential during pregnancy.
Experts Agree: This Is The Healthiest Vegetable In The World
Key Takeaways. Broccoli has slightly higher levels of vitamins C and K as well as calcium, iron, and protein. Cauliflower is slightly lower in calories and carbohydrates than broccoli, making it a popular choice for those following a low-carb diet.
No, cauliflower is not genetically engineered or artificially created in a lab. It's the result of centuries of selective breeding from wild cabbage (Brassica oleracea), making it "man-made" only in the agricultural sense that humans guided its development through traditional farming practices.
Cauliflower can cause gas and bloating due to its fiber and sulfur-based compounds that ferment in the gut. If you take the blood thinner warfarin, consuming large amounts of cauliflower can interfere with the medication's effectiveness due to its vitamin K content. Keeping vitamin K intake stable is essential.
Cauliflower is high in fiber, with two grams of fiber in every cup. 9 Getting enough fiber in your diet helps reduce inflammation and improve digestive health.
Supports liver function
Cauliflower is a great source of choline — a nutrient many of us don't get enough of. Your body needs choline to move fat out of your liver and keep it healthy. It also supports memory, mood and muscle control.
Cruciferous vegetables (broccoli, kale, Brussels sprouts, cauliflower, cabbage, etc.) have a very unique compound of phytonutrients that can help decrease stomach fat.
As with other cruciferous vegetables, Messer says that cauliflower can cause digestive issues such as bloating or gas in some people. "This can be uncomfortable and even embarrassing," she says, adding that such people can improve this by eating smaller amounts.
Starchy vegetables (e.g. potatoes, corn) and acidic vegetables (e.g. tomatoes, bell peppers): this combination is believed to lead to digestive discomfort and potential acid reflux.
The Dirty Dozen
For the EWG listing, strawberries are at the top of the “Dirty Dozen” category. They are followed by apples, nectarines, peaches, celery, and grapes. Making up the 2nd half of that list are cherries, spinach, tomatoes, sweet red peppers, cherry tomatoes, and cucumbers.
In this article, we look at 19 of the healthiest vegetables and suggest ways to enjoy them as part of a balanced diet.
Cruciferous vegetables, including broccoli, cabbage, kale, and cauliflower have been found to lower blood pressure, in comparison to root and squash vegetables, in middle-aged and older Australian adults with elevated blood pressure.
Vegetables that get a bad rap
The countries with the highest volumes of cauliflower and broccoli consumption in 2019 were China (11M tonnes), India (9.2M tonnes) and the U.S. (1.2M tonnes), with a combined 78% share of global consumption. These countries were followed by Mexico, which accounted for a further 1.9%.
And now, for the Don't Worry list, the Clean 15 with the lowest pesticide load. This is courtesy of Dr, Andrew Weil: avocados, sweet corn, pineapples, cabbage , sweet peas (frozen), onions, asparagus, mangoes, papayas, kiwi, eggplant, grapefruit, cantaloupe (domestic), cauliflower, sweet potatoes.
What GMO crops are in the United States?
Besides offering a lower-starch option, cauliflower also packs a lot more nutrition than a simple white potato or white rice, especially the latter.
Whether you prefer them fresh or frozen, raw or cooked, below are vegetables that can help with your weight loss goals.
“Cauliflower, like cabbage, is considered a high-FODMAP cruciferous veggie,” Volpe explains. “It is naturally high in raffinose (a poorly digested carbohydrate constituent) as well as in glucosinolates.” A less-gassy substitute for cauliflower, believe it or not, is broccoli.
