Scientifically known as radicchio C. intivus L.Group Rubifoliumis a type of chicory (Varieties of Cichorium L.) Popular in northeastern Italy, central Europe, and North America. Like other chicory species, radicchio traces its origins to the Mediterranean region, but it can be grown in temperate and semi-arid regions around the world.
Radicchio is a leafy vegetable with a bitter taste that is highly valued for its attractive color, texture, and nutritional value. It is often mistaken for red cabbage or red lettuce. It typically has a more pronounced bitterness and a rich, crunchy texture compared to the soft, leafy texture of lettuce or the crunchy, waxy texture of cabbage.
Radicchio comes in two color groups: red and variegated. Red radicchio has red leaf blades with white veins in the center, while variegated radicchio has yellow-green leaf blades with green, red, and whitish spots and lines. Both types offer potential health benefits and rich nutrition.
Chicory contains beneficial plant compounds, including phenolic compounds such as hydroxycinnamic acid and hydroxybenzoic acid. Red varieties also contain anthocyanins. These healthy plant compounds exhibit antioxidant properties.
Antioxidants fight oxidative stress caused by free radicals that are naturally formed in the body and caused by exposure to environmental factors such as pollution and sunlight. This stress is associated with diseases such as cancer, cardiovascular disease, diabetes, eye disease, and neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease. Although these diseases are usually thought to be caused by chronic oxidative stress, it is only one of the factors that can influence the disease.
Beneficial plant compounds found in radicchio and other chicory varieties show promise in combating oxidative stress. However, it is essential to recognize the current limitations of research, which is primarily conducted in test tubes and animals. These studies are looking at its antioxidant properties, ability to reduce inflammation, fight microorganisms, protect the stomach, and potentially inhibit tumor growth. Further research is needed to fully understand the therapeutic effects of chicory and establish more solid conclusions.
Leafy vegetables such as radicchio are rich in vitamin K, an important nutrient for proper blood clotting. One cup of shredded raw radicchio contains 102 micrograms of vitamin K, covering 85% of the recommended intake or daily value (DV) for this nutrient.
Vitamin K is essential for healthy bones, and human studies have shown that low vitamin K intake and low vitamin K in the bloodstream are associated with an increased risk of bone fractures. It has been.
Furthermore, vitamin K’s antioxidant and anti-inflammatory properties may not only reduce the risk of bone fractures, but may also help prevent age-related diseases such as neurodegenerative diseases, cardiovascular disease, cancer, and diabetes. suggests.
Radicchio is a source of lutein and zeaxanthin, which are carotenoids (pigments) that are also found in foods such as kale, Brussels sprouts, corn, and egg yolks.
Lutein and zeaxanthin are unique in that they are the only carotenoids present in the retina. They play an important role in promoting eye health and protecting against eye diseases such as age-related macular degeneration and cataracts.
One cup of shredded raw radicchio contains a total of 3,530 micrograms (or 3.53 milligrams) of these beneficial compounds. 100 grams (3.5 ounces) of shredded raw radicchio contains 8.83 milligrams (mg) of lutein and zeaxanthin. To put this into perspective, Brussels sprouts contain 1.59 milligrams per 100 grams, while other foods such as kale contain 39.55 milligrams.
Although there is no set daily intake amount for lutein and zeaxanthin, researchers recommend aiming for about 10 milligrams of lutein and about 2 milligrams of zeaxanthin per day to maintain optimal eye health. doing.
1 cup of shredded raw radicchio contains:
- calorie: 9.2 calories
- protein: 0.572 grams (g)
- fat: 0.1g
- carbohydrates: 1.79g
- fiber: 0.36g
In addition to its rich vitamin K content, radicchio is an excellent source of copper, with 0.136 milligrams (15% of your daily value) in 1 cup. Copper plays an important role in our bodies, helping produce energy, building connective tissue, and maintaining healthy blood vessels. It is also important for brain development, gene activation, and support for the nervous and immune systems.
Radicchio also contains 0.904 milligrams of vitamin E, which is 6% of your daily value. Vitamin E acts as an antioxidant, protecting cells from free radical damage. Additionally, it supports the immune system and dilates blood vessels to prevent internal clotting.
Radicchio is generally safe to consume. However, this is a type of chicory, and rare cases of chicory allergy have been recorded. In most cases, adults come into contact with chicory in the course of their occupation. Reported allergic reactions include rhinoconjunctivitis, asthma, anaphylactic reactions, and contact dermatitis.
People with allergies to Asteraceae (including lettuce), birch pollen allergies, and people with atopic dermatitis commonly ingest or come into contact with inulin (a type of fiber found in chicory) or chicory. We recommend that you be careful when doing so. – Foods containing.
If you suspect you have a food allergy, especially if you’re not sure if you’re allergic to radicchio or any other type of food, it’s important to see your health care provider for a proper diagnosis.
To get the most out of radicchio in your diet, we recommend first learning how to store it properly. The Centers for Disease Control and Prevention (CDC) recommends that leafy greens, like many other produce, be stored in a clean refrigerator at temperatures below 40 degrees Fahrenheit.
Storing leafy greens such as radicchio in the crisper drawer provides a slightly higher humidity level, which helps maintain freshness, prevents wilting, and extends shelf life. Whether you wash your produce before storing it or just before eating it, it’s important to make sure your produce is completely dry before storing it.
The CDC recommends washing leafy greens that have not been prewashed thoroughly under running water before eating, cutting, or cooking them. Do not soak leafy vegetables in water. Soaking can transfer bacteria from leaf to leaf.
