What are Carotenoids?

Carrots and other brightly coloured fruits and vegetables owe their pigmentation, in part, to a group of fat-soluble phytonutrients called carotenoids, which are loaded with antioxidants. Carrots, tomatoes, dark green leafy vegetables, sweet potatoes, and many other natural foods wouldn’t be as colourful or as nutritious without them.
​
Carotenoids are essential nutrients that help protect against oxidative stress and benefit our health in many ways, but since our bodies don’t produce them, the only way to get carotenoids is through the foods we eat and from carotenoid supplements. So, let’s talk about the benefits of carotenoids and how to get more of them in your diet.

Researchers believe that many of the benefits of carotenoids are due to their free-radical fighting potential. Carotenoids act as antioxidants to help combat damage from oxidative stress. They are among the most robust antioxidants nature has to offer, and different carotenoids have an affinity for different areas of the body. The carotenoids that have been most studied for their health benefits include beta-carotene, lycopene, lutein and zeaxanthin.
Carotenoid Health Benefits:

• Antioxidant Support
  When you consume carrots or other carotenoid-rich foods, you are consuming antioxidants that help fight oxidative stress, which is believed to be a major contributor to aging and age-related health concerns. Also, antioxidants may be one of the best ways to support cardiovascular health.
• Vision Health
  Both lutein and zeaxanthin, two well-studied carotenoids, have been shown in multiple clinical studies to help promote vision health and protect your eyes from the harmful effects of blue light exposure.Age-related vision concerns are common in older Americans, so many doctors and nutritionists recommend eating plenty of carotenoid-rich fruits and vegetables.
• Skin Health
  While not strong enough on their own to protect you from the damaging effects of too much sun exposure, carotenoids may work to help your body protect itself from ultraviolet rays.Once converted from source carotenoids, active vitamin A may help reduce oxidative damage caused by the sun. Studies have shown that some carotenoids may also help protect skin tissue and cells from environmental toxins.
• Immune Health
  A higher intake of carotenoids is associated with a natural boost in immune health.8 Along with antioxidants, carotenoids are also known to contain acetylenics, a group of metabolites that have been studied for their potential role in promoting wellbeing and boosting immune function.

While beta-carotene, lycopene, lutein and zeaxanthin might be the most studied carotenoids, you may not know a lot about them. Let’s take a closer look.
Common Carotenoids

• Beta-Carotene
  Your body converts beta-carotene to vitamin A, an essential nutrient that has antioxidant activity and helps protect your cells from damage. Beta-carotene is found in fruits, vegetables and some whole grains.
• Lycopene
  Lycopene is responsible for giving many fruits and vegetables (especially tomatoes) their red color. While not considered an essential nutrient, its potential benefits include everything from promoting skin health to cardiovascular support. Lycopene has also been studied for supporting prostate health10 and is a popular ingredient in many men’s health supplements.
• Lutein
  There is abundant evidence that shows lutein may help support vision health and generally provides a protective effect for the eyes.
• Zeaxanthin
  Together, zeaxanthin and lutein are the predominant carotenoids in the macula and retina6 and both help absorb blue light, a particularly harmful type of light from electronic devices and other light sources. These two carotenoids are among the most well-studied and well-documented natural vision protectors.
• Astaxanthin
  Astaxanthin is a high-powered antioxidant with a molecular structure that makes it very effective at neutralizing free radicals. Like most carotenoids, its benefits include support for vision, skin, joint and immune health.11

Foods Rich in CarotenoidsLook for vibrant color in the produce section as your guide for choosing foods rich in carotenoids. According to Dr. Michael Roizen, “You can spot carotenoids by the red, orange, green, and yellow color they impart to foods such as tomatoes, carrots, and apricots—basically, any fruit or vegetable with these hues. Also, carotenoids are plentiful in dark leafy green vegetables: spinach, broccoli and kale. Carotenoids are one of the reasons eating a diet rich in fruits and vegetables can help keep you young.”
Fruits and vegetables are the most common sources, but egg yolks and red- or orange-pigmented seafood are also sources of carotenoids. Here’s a list of carotenoid superfoods you can get at the grocery store:
