Scientists at the University of Southampton have gained new insight into the health benefits of zeaxanthin, a nutrient found in green leafy vegetables such as kale and spinach. According to their research, zeaxanthin may have anti-inflammatory properties that may improve cardiovascular health.

The study in mice found that a diet rich in zeaxanthin prevented white blood cells from building up in the arteries. This buildup, known as leukocyte adhesion, is a major factor in the development of atherosclerosis, a disease in which plaque builds up in arteries and restricts blood flow.

Lead researcher Professor John Mayer said the findings could have important implications for human health. “If we can show that zeaxanthin has the same effect in humans, it may provide a new way to prevent and treat cardiovascular disease,” he said.

Zeaxanthin is known for its eye health benefits, as it has been shown to prevent age-related macular degeneration, the leading cause of blindness in older adults. However, this new study suggests that its health benefits may extend beyond eye health.

Many people do not get enough zeaxanthin in their diet. According to the USDA, the average daily allowance for zeaxanthin is only about 0.5 milligrams, well below the recommended daily allowance of 2 milligrams.

However, including more green leafy vegetables in your diet may be an easy way to increase your zeaxanthin intake, says registered dietitian Jessica Levinson. “Adding kale or spinach to smoothies, salads or stir-fries is a great way to boost your zeaxanthin intake,” she says.

Additionally, supplements containing zeaxanthin are readily available. However, it is important to speak with a healthcare provider before taking any supplements, as they may interact with certain medications or medical conditions.

While more research is needed to confirm these findings in humans, this research provides new insights into the potential health benefits of zeaxanthin. Including more green leafy vegetables in your diet or taking zeaxanthin supplements may help promote cardiovascular health and prevent disease.
