Citrus bioflavonoids are beneficial compounds found in citrus fruits. Unlike the vitamin C in citrus fruits, citrus bioflavonoids are not essential for health. However, they do have many health promoting properties. In fact, citrus bioflavonoids are so beneficial that they are widely used in Europe to treat diseases of the blood vessels and lymph system. There are several different citrus bioflavonoids, and each of them has its own distinct health benefiting properties.
Hesperidin is one of the most widely studied citrus bioflavonoids. Researchers have found that it can help many different problems, including allergies, high blood pressure, menopause symptoms, premenstrual syndrome symptoms, osteoporosis, and inflammation. One of the biggest benefits from hesperidin is its ability to help blood vessels. It can be particularly useful for circulation problems and varicose veins.
If you like grapefruit, you are in luck because naringin is a very healthy citrus bioflavonoid found primarily in grapefruit. Naringin has been demonstrated to lower cholesterol levels. It can also help with retinal diseases that are linked to diabetes, and it even works to prevent cancer! If this has you wanting to add grapefruit to your diet, just make sure you aren’t on any medications that are affected by grapefruit. Grapefruit is notorious for interfering with medication.
Rutin is a citrus bioflavonoid that is also found in other plants, fruits, and vegetables. Rutin is a strong antioxidant, meaning it is great at getting rid of harmful free radicals in the body. In addition to acting as an antioxidant, rutin also stabilizes vitamin C, making it more available to the body. Of even more interest is rutin’s ability to fight cancer. Early studies indicate that rutin can inhibit precancerous and cancerous growths!
Quercetin is another citrus bioflavonoid that is abundant in many plants. Perhaps due to its abundance, quercetin has been studied quite a bit, and it has been found to have many health benefits. Quercetin is an excellent anti-inflammatory compound. It inhibits inflammatory enzymes, which cause systemic inflammation. It also inhibits the release of histamine, which is good news for people with allergies. Histamine is what causes allergic reactions!
Tangeretin has a very bitter flavor, and it is found mostly in the peel of citrus fruits. However, you do not have to eat the peel to get tangeretin because it is found in smaller quantities in the whole fruit. You can even get small amounts in orange juice. Tangeretin has not been widely studied, but the few studies that have been done demonstrate it has neuroprotective benefits, and may help protect against decline in neurological function.
Nobiletin is also found in the peels of citrus fruits, and it is also very bitter. Like other citrus bioflavonoids, nobiletin has anti-inflammatory and anti-cancer benefits. Nobiletin also has the unique ability to help prevent memory loss, and it may even be useful for treating acne.
Beginning in the 1960s, diosmin was used therapeutically for vein disorders. Specifically, diosmin is very helpful for treating chronic venous insufficiency, which occurs when veins have difficulty returning blood from the legs to the heart. Taking diosmin has been shown to have significant improvement in chronic venous insufficiency. It has also demonstrated the ability to decrease high blood pressure and regulate blood sugar.
Citrus bioflavonoids have many health benefits, and they are just one more reason to include citrus fruits in your diet. To get the most benefit from the citrus you eat, be sure to consume the white pith. It may be a little bitter, but it has a high concentration of citrus bioflavonoids. Are you going to start eating more citrus fruit to get the benefit of citrus bioflavonoids?
