Is Radicchio Acidic? Radicchio and Acid Reflux
Radicchio, the vibrant red and white leafy vegetable often used in salads and Italian dishes, is not only known for its slightly bitter taste but also for its numerous health benefits. For individuals managing acid reflux or GERD (gastroesophageal reflux disease), questions often arise about the acidity of certain foods. So, “Is radicchio acidic, and is it safe for people with acid reflux?”
The good news is that radicchio is not highly acidic and is generally considered a low-acid food. Its pH level, along with its high nutrient and water content, makes it a safe and even beneficial choice for most people with acid reflux. In fact, its natural bitterness can stimulate digestion and improve overall gut health when consumed in moderation.
In this article, we’ll explore radicchio’s acidity, its effects on acid reflux, and how to incorporate it into a reflux-friendly diet.
Is Radicchio Acidic or Alkaline?
Radicchio is considered a low-acid to mildly alkaline food, with a pH level ranging from 5.5 to 6.5. This makes it less acidic than trigger foods like citrus fruits, tomatoes, or coffee, which are known to exacerbate acid reflux symptoms.
In addition to its relatively neutral pH, radicchio’s high water content and fiber make it easier to digest and less likely to irritate the esophagus or stomach lining. For these reasons, radicchio is generally safe for individuals with acid reflux or GERD.

Nutritional Profile of Radicchio
Radicchio is more than just a colorful addition to your plate—Health expert suggest that it’s packed with essential nutrients and antioxidants that promote overall health and support digestion. Here’s what makes radicchio a great choice:
1. High Water Content
- Radicchio is composed of nearly 93% water, making it hydrating and gentle on the digestive system. This can help dilute stomach acid and reduce reflux episodes.
2. Rich in Fiber
- One cup of radicchio contains about 2 grams of fiber, which supports healthy digestion, regulates bowel movements, and prevents overeating—one of the most common triggers for acid reflux.
3. Loaded with Antioxidants
- Radicchio contains powerful antioxidants such as anthocyanins, which give it its red-purple color and help reduce inflammation in the digestive tract.
- It’s also rich in vitamin C, which strengthens the immune system and protects cells from damage.
4. Source of Essential Minerals
- Potassium: Supports muscle function, including the lower esophageal sphincter (LES), which helps prevent acid reflux.
- Magnesium: Relaxes the muscles in the digestive system and reduces reflux episodes.
5. Low in Calories
- With only 9 calories per cup, radicchio is a light and easily digestible option for those managing reflux.
Benefits of Radicchio for Acid Reflux
Radicchio’s nutrient profile makes it a good choice for managing acid reflux symptoms. Here are some of its key benefits:
1. Soothes the Stomach
- Radicchio’s high water content helps dilute stomach acid and soothes the digestive tract, reducing the risk of irritation to the esophagus.
2. Improves Digestion
- The fiber in radicchio promotes healthy digestion, prevents constipation, and reduces bloating—common issues that can exacerbate reflux.
3. Supports the Lower Esophageal Sphincter (LES)
- Minerals like potassium and magnesium in radicchio support the LES, preventing stomach acid from traveling back into the esophagus.
4. Reduces Inflammation
- The antioxidants in radicchio, particularly anthocyanins, help reduce inflammation in the esophagus caused by acid reflux.
5. Stimulates Bile Production
- Radicchio’s natural bitterness stimulates bile production, aiding in the digestion of fats and promoting smoother digestion.
Tips for Including Radicchio in a GERD-Friendly Diet
Radicchio can be a delicious and versatile addition to your meals, but it’s important to prepare it in a way that won’t trigger reflux symptoms. Follow these tips:
1. Avoid Acidic Dressings
- Pair radicchio with non-acidic dressings like olive oil or yogurt-based dressings instead of vinegar or citrus-based options.
2. Cook Lightly
- Cooking radicchio by steaming, grilling, or roasting can reduce its bitterness and make it easier to digest, especially for those with sensitive stomachs.
3. Combine with Alkaline Foods
- Pair radicchio with other reflux-friendly ingredients like cucumbers, zucchini, or lean proteins to create a balanced, low-acid meal.
4. Avoid Overeating
- Even low-acid foods can cause reflux if consumed in large quantities. Stick to moderate portions to prevent stomach discomfort.
5. Test Your Tolerance
- Everyone’s digestive system is different. If you’re trying radicchio for the first time, start with a small serving to see how your body reacts.

Tomato Soup
Yesterday, I was working at Starbucks (Freelancers Central) when a lady standing by the doors tipped over into a drug-induced trance.
The baristas immediately called 9-1-1, but the woman sitting next to me, the one who’d seen the whole incident go down because she’d been standing outside making a phone call when it happened, just shook her head and informed me that the lady was ‘as high as a kite.’
Now that’s a feeling I can relate to. That world-weariness. After all, I had gone to school in the most psychedelic college town in the country (Berkeley), and lived in what is probably the most homeless-friendly big city in the WORLD (San Francisco). I’ve seen it all—so what if I’m only 26?—all the different variations of drug-induced catatonia and rants and everything in between.
This old man with white hair, he’s a regular who just hangs out in the cafe all day chatting with other regulars (except me, because I avoid eye contact with strangers, much in the style of Amelie Poulain), leapt up from his seat and raced outside, wanting to take charge of the situation. He reminded me of one of those alert guard dogs, the kind that’s been bred to inspect signs of disorder, and cleared aside the small crowd that had gathered around the woman to get a closer look.
He re-entered the cafe a few minutes later. “She’s on drugs,” he said disgustedly.
A few minutes later, the lady dizzily pushed herself up and teetered away. “She’s only on drugs,” Mr. Regular repeated, shaking his head.
This was when the firemen rushed onto the scene. They pulled up in their shiny truck with their sirens blaring, and parked gracefully into the empty space in front of the building that just happened to be big enough for one regular-sized fire truck.
“Did they need to bring so many men?” the woman beside me asked. Sure enough, five firemen stepped out, clad in their heavy protective gear. Men who meant business. Men who looked like they were ready to put out a fire.
“She doesn’t need firemen,” said Regular Man. “She needs to be slapped in the face and drenched with tomato soup!”
Tomato soup, now that’s an idea.

Did he mean what he said sadistically? Was he implying that the lady should be burned with a hot, acidic liquid as a sort of punishment? Or maybe he thought it would revivify her, the equivalent of pushing her into a molten pool. Or maybe he just wanted tomato soup for dinner and had made a Freudian slip.
Whatever the case, guessing does not change the fact: these are the kinds of moments that can inspire meals. I’m very easily persuaded, and I happen to really like tomato soup.

This recipe is one I’ve been making since my student days, so you can be sure that it’s low-maintenance. And it came in handy during my time in San Francisco, a city whose 365-days-per-year fog and gloom is enough to drive a person mad. You see, you need a soup as heartening as this to keep your spirits up, lest you succumb to drastic measures. Like quitting your job and chasing summer in the Southern Hemisphere. Well, that latter part was unintentional.
I don’t remember how I came upon this recipe anymore. I copied it long ago into a little pocket notebook that I have on me at all times—we all have one of these, I suspect—and have been faithfully following the same set of directions for a long time. I’m sure its source is not as obscure as I make it seem, but I prefer to keep it a mystery, for the sake of having a “family recipe” that I can pass down for generations. Or not. I don’t think that far ahead. (But it would be cool nonetheless.)
