From the citron, other hybrid citrus species began springing up such as oranges, lemons, limes, pomelos, mandarins and others. Spanish travelers introduced the sweet orange to the American continent, while it is believed that Christopher Columbus brought citrus seeds to be planted on the island of Haiti on his second voyage in the year of Wherever they were found, precious citrus fruits were used as a fragrance and as a flavor added to sweets and tea.

Citrus fruits were well known for their medicinal properties and were used to combat sickness, intestinal ailments, skin conditions, gout, scurvy and even used as an antidote to poison and as an antiseptic during times of plague. Today, we know much more about what gives citrus its superior standing.

I would like to highlight some nutrients and phytochemicals that give those fruits their remedy qualities:. Vitamin C ascorbic acid is one of the most popular vitamins in the world.

Citrus fruits are notably rich in vitamin C. This vitamin is needed to form and maintain healthy skin, bones, blood vessels and connective tissues.

Vitamin C plays an important role in supporting the immune system and also acts as an antioxidant that might help protect your cells against the effects of free radicals and fight inflammation.

By reducing inflammation, vitamin C may prevent or delay heart disease conditions like arthritis and some types of cancer. Vitamin C helps the body to absorb iron from plant foods the non-heme iron.

Therefore, eating a citrus fruit alongside plant foods like leafy green vegetables, nuts, seeds and legumes will help the body better absorb iron. Citrus fruits are rich in vitamin C that is essential for building healthy body tissues. But the protective benefits of citrus fruits are not limited to only one nutrient, they expand to numerous nutrients, among them a large plant compound family called the Flavonoids.

Flavonoids are plant-based nutrients phytonutrients responsible for the plant qualities such as its bright color and the familiar aroma. Citrus fruits represent an important source of dietary flavonoids including hesperidin, hesperetin, naringin, naringenin, diosmin, quercetin, rutin, nobiletin, tangeretin and others.

Flavonoids also have multiple therapeutic benefits. Studies indicate that citrus flavonoids protect the cells against the damage of free radicals. Through a direct scavenging of free radicals, citrus flavonoids can reduce inflammation.

Consequently, those anti-inflammatory pathways provide therapeutic benefits against cancer, neurodegenerative disorders, atherosclerosis, cardiovascular disease CVD and against diabetes.

Citrus flavonoids can protect against diabetes by improving glucose tolerance, increasing insulin secretion and sensitivity, and decreasing insulin resistance and also may play a significant role in the development of antiobesity agents, reducing obesity and adipose tissue inflammation.

Last but not least, citrus flavonoids have the ability to modulate gut bacteria microbiome composition and activity and exert beneficial effects on intestinal barrier function and gastrointestinal GI inflammation.

This effect on GI microbiome suggests that intake of citrus flavonoids can contribute to improved GI functioning and health. With all the health promoting qualities mentioned above, we cannot ignore the beneficial effects of a well-known macronutrient, the Dietary Fiber.

Dietary Fiber is a type of complex carbohydrate found in plant foods. It is made of many sugar molecules linked together in a way that cannot be entirely digested in the small intestine.

Citrus fruit rinds, or peels, contain limonene. There are potential health benefits of limonene, but more research is needed. Limonene is the oil extracted from the peels of oranges and other citrus fruits 1. People have been extracting essential oils like limonene from citrus fruits for centuries.

Today, limonene is often used as a natural treatment for a variety of health issues and is a popular ingredient in household items. Limonene is a chemical found in the rind of citrus fruits, such as lemons , limes, and oranges.

Limonene belongs to a group of compounds known as terpenes, whose strong aromas protect plants by deterring predators 3. Limonene is one of the most common terpenes found in nature and may offer several health benefits.

It has been shown to possess anti-inflammatory, antioxidant, anti-stress, and possibly disease-preventing properties. Limonene is an essential oil found in citrus fruit peels. It belongs to a class of compounds called terpenes. Limonene is a popular additive in foods, cosmetics, cleaning products, and natural insect repellants.

Limonene is extracted through hydrodistillation, a process in which fruit peels are soaked in water and heated until the volatile molecules are released via steam, condensed, and separated 4.

Due to its strong aroma, limonene is utilized as a botanical insecticide. Other household products containing this compound include soaps, shampoos, lotions, perfumes, laundry detergents, and air fresheners. Additionally, limonene is available in concentrated supplements in capsule and liquid form.

These are often marketed for their supposed health benefits. This citrus compound is also used as an aromatic oil for its calming and therapeutic properties. Limonene is used in a range of products, including food, cosmetics, and eco-friendly pesticides.

It can also be found in supplement form, as it may boost health and fight certain diseases. Limonene has been studied for its potential anti-inflammatory, antioxidant, anticancer, and heart-disease-fighting properties.

However, most research has been conducted in test tubes or on animals, making it difficult to fully understand the role of limonene in human health and disease prevention. Limonene has been shown to reduce inflammation in some studies 6 , 7.

Limonene has been shown to reduce inflammatory markers that relate to osteoarthritis, a condition characterized by chronic inflammation. A test-tube study in human cartilage cells noted that limonene reduced nitric oxide production. Nitric oxide is a signaling molecule that plays a key role in inflammatory pathways 9.

In a study in rats with ulcerative colitis — another disease characterized by inflammation — treatment with limonene significantly decreased inflammation and colon damage, as well as common inflammatory markers Limonene has demonstrated antioxidant effects as well.

Antioxidants help reduce cell damage caused by unstable molecules called free radicals. Free radical accumulation can lead to oxidative stress, which may trigger inflammation and disease One test-tube study revealed that limonene may inhibit free radicals in leukemia cells, suggesting a decrease in inflammation and cellular damage that would normally contribute to disease Limonene may have anticancer effects.

In a population study, those who consumed citrus fruit peel, the major source of dietary limonene, had a reduced risk of developing skin cancer compared to those who only consumed citrus fruits or their juices Additionally, research in rodents found that supplementing with limonene inhibited the growth of skin tumors by preventing inflammation and oxidative stress Other rodent studies indicate that limonene may fight other types of cancer, including breast cancer Heart disease remains the leading cause of death in the United States, accounting for nearly one in four deaths Limonene may lower your risk of heart disease by reducing certain risk factors, such as elevated cholesterol, blood sugar, and triglyceride levels.

In one study, mice given 0. In particular, it showed the citrus bioflavonoid naringin displayed strong anti-inflammatory and antioxidant activities.

They are ideal for applications targeting support for the immune system, respiratory health, cognitive health, vascular integrity, metabolism, cholesterol, joint health, and systemic antioxidant support. Citrus bioflavonoids are versatile, making them excellent ingredients for food, beverage, and dietary supplement applications.

They may be used in a variety of beverages, as they are suspendable in liquids. Citrus bioflavonoids also act as natural preservatives, another benefit for food and beverage products; they also provide bitter and sour taste notes for some specialty beverages, including beer.

Drawing from a larger selection of citrus provides more opportunity for customization. Bioflavonoids sourced from orange, lemon, lime, tangerine, and grapefruit provide the broadest bioflavonoid profiles. Each one provides its own unique profile, creating more opportunities for customized formulations.

The ability to extract very specific bioflavonoids in their purest form is made possible through advanced production methods and extraction technologies. Standardization of extracts is also important.

Standardized bioflavonoid ingredients ensure consistency and quality in every batch. Today, there are options for customer-specific formulations, made possible through advances in the variety of citrus complexes and purified extracts available.

Brewster pioneered advances in citrus bioflavonoids and concentrated citrus extracts. With over 80 years of experience, Brewster Nutrition and its marketing arm, IBN, now produce over botanical ingredients of quality and value-added solutions for condition-specific formula applications.

From plant proteins and adaptogens to sugar reduction and blood sugar management, the range of weight wellness formulation options is expanding. Best sources: Extra virgin olive oil goes through less refining and processing, so it retains more nutrients than standard varieties.

Avocado and safflower oils have shown cholesterol-lowering properties, while walnut oil has 10 times the omega-3s that olive oil has. Beans How much: About one cup, twice a week or more. Why: Beans are loaded with fiber and phytonutrients, which help lower CRP, an indicator of inflammation found in the blood.

At high levels, CRP could indicate anything from an infection to RA. In a study scientists analyzed the nutrient content of 10 common bean varieties and identified a host of antioxidant and anti-inflammatory compounds. Beans are also an excellent and inexpensive source of protein and have about 15 grams per cup, which is important for muscle health.

Best sources: Small red beans, red kidney beans and pinto beans rank among the U. Whole Grains How much: Eat a total of six ounces of grains per day; at least three of which should come from whole grains. One ounce of whole grain would be equal to ½ cup cooked brown rice or one slice of whole-wheat bread.

Why: Whole grains contain plenty of filling fiber — which can help you maintain a healthy weight. Some studies have also shown that fiber and fiber-rich foods can lower blood levels of CRP, an inflammatory marker. Best sources: Eat foods made with the entire grain kernel, like whole-wheat flour, oatmeal, bulgur, brown rice and quinoa.

Some people may need to be careful about which whole grains they eat. Gluten — a protein found in wheat and other grains — has been linked to inflammation for people with celiac disease CD or gluten sensitivity.

Nightshade Vegetables Why: Nightshade vegetables , including eggplant, tomatoes, red bell peppers and potatoes, are disease-fighting powerhouses that boast maximum nutrition for minimal calories.

Why not: They also contain solanine, a chemical that has been branded the culprit in arthritis pain. Test it: Some experts believe these vegetables contain a potent nutrient mix that helps inhibit arthritis pain.

However, many people do report symptom relief when they avoid nightshade vegetables. So, if you notice that your arthritis pain flares after eating them, consider eliminating all nightshade vegetables from your diet for a few weeks to see if it makes a difference.

Then slowly add them back into your diet to see if symptoms worsen or stay the same. Today, 1 in 4 adults in America live with arthritis Nearly 60 million adults and children in America are diagnosed with arthritis, and most have pain that interferes with their daily lives.
