You are on the right track if you said they are both orange! Carotenoids are the substances that make carrots and calendula orange. More than 600 varieties of carotenoids are found in plants, which contribute to their yellow, orange, and red tones. These colors are most noticeable in autumn when leaves change to fiery yellow, orange, and red shades.
Why do plants have carotenoids? Carotenoids act as potent antioxidants that shield plants from oxidative stress caused by factors like sunlight, pollution, and radiation. If you've ever seen a plant turn yellow due to excessive sunlight exposure, that color change results from the carotenoids working to safeguard the plant from the sun's rays.
These antioxidant carotenoids function the same way inside the human body. When we ingest foods high in carotenoids, we take in these phytochemicals that help protect us from oxidative stress and free radicals. Humans are subject to oxidative stress from smoking, obesity, and alcohol, as well as from sunlight, pollution, and radiation. Carotenoids accumulate in body tissue, providing antioxidant protection for cell membranes. They also contribute to cell growth and the proper function of the immune and nervous systems. Carotenoids also accumulate in the skin, which helps to protect your skin from damage and sunburn from UV rays.

These powerful antioxidants are known for combating premature aging by neutralizing harmful free radicals that can damage cells and accelerate the aging process. In addition to their anti-aging properties, carotenoids reduce the risk of cardiovascular issues such as heart disease and stroke.
Carotenoids have also been linked to a lower risk of developing diseases like arthritis and cancer. By helping to quell inflammation throughout the body, these compounds can alleviate symptoms associated with inflammatory conditions and promote better overall health and wellness.
One notable example of the benefits of carotenoids is their presence in calendula, a well-known herbal remedy with a wide range of therapeutic properties. Calendula is particularly effective in addressing inflammatory issues such as sunburn, cuts and scrapes, bug bites, slow-healing wounds, and inflammation of the oral mucosa. Clinical studies have even demonstrated that calendula can protect the skin from the damaging effects of radiation therapy, highlighting its potential as a natural treatment option for various skin conditions.
Some of the most well-known carotenoids include lycopene, beta-carotene, and lutein, each offering unique benefits to the body. Lycopene, for instance, is commonly found in tomatoes, giving them their vibrant red color. Beta-carotene is abundant in carrots, sweet potatoes, and yellow, red, and orange bell peppers, providing these vegetables with their characteristic hues. Lutein, on the other hand, can be found in foods like kale, nettles, and spinach, although its yellow color is often masked by the dark green pigments of these leafy greens.
In addition to the above sources, carotenoids can also be found in calendula, squash, citrus fruits, and pumpkins. These compounds are responsible for the bright yellow color of turmeric, known for its anti-inflammatory properties. By incorporating a diverse range of fresh fruits and vegetables into your diet, you can ensure that you are receiving a variety of carotenoids that help protect your body from oxidative stress caused by free radicals. This diverse intake not only safeguards you from potential damage but also reduces the risk of developing inflammatory diseases, making it essential for maintaining optimal health and well-being.
