What Is Tomato Lycopene and What Are Its Benefits?

Lycopene is a natural compound found in certain plant-based foods, most notably in tomatoes. This pigment is responsible for the vibrant red color of many fruits and vegetables. Beyond its role in nature, lycopene has garnered significant attention for its interaction with human health. This article will explore the specifics of what tomato lycopene is, its association with health, and how its uptake by the body can be improved through simple preparation methods.

Defining Lycopene and Its Tomato Connection

Lycopene is a carotenoid, a type of natural pigment produced by plants that creates bright red, yellow, and orange hues. Its specific chemical structure allows it to absorb most visible light, reflecting the deep red wavelengths that we see. This property makes it a principal pigment in ripe tomatoes.

Tomatoes and processed tomato products are the most significant source of lycopene in the average diet. The name “lycopene” itself is derived from the tomato’s former genus name, Lycopersicon, highlighting this connection. While other foods like watermelon and pink grapefruit also contain this compound, tomatoes are particularly abundant in it. The concentration of lycopene increases as the fruit ripens, transforming from green to a rich red.

The specific variety of the tomato also influences its lycopene content. Smaller, more concentrated types like cherry and Roma tomatoes contain higher levels of the compound compared to larger varieties. The way tomatoes are grown can also have an impact, as some research suggests that homegrown tomatoes may contain more lycopene than some commercially produced ones.

Health Aspects Associated with Tomato Lycopene

Lycopene’s health benefits are largely tied to its function as an antioxidant. Antioxidants are molecules that neutralize unstable molecules in the body called free radicals. When free radicals accumulate, they can cause a state of oxidative stress, which is linked to cellular damage. Lycopene’s structure makes it effective at quenching these molecules, helping to protect cells from damage.

Research has explored the link between diets rich in tomato lycopene and cardiovascular health. Some studies suggest that regular intake of lycopene is associated with improved cholesterol levels and a reduced risk of developing heart disease. Observational studies have noted that individuals with higher blood levels of lycopene may have a lower risk of stroke.

Lycopene is also connected to skin health, as its antioxidant properties may offer a degree of protection against sun-induced damage. While it is not a substitute for sunscreen, studies have indicated that dietary lycopene can help shield the skin from UV radiation at a cellular level.

Enhancing Lycopene Bioavailability from Tomatoes

The amount of lycopene your body can absorb and use, a concept known as bioavailability, is not always highest in raw tomatoes. The lycopene in raw tomatoes is tightly bound within the plant’s cell walls. This structure makes it more difficult for the body to access and absorb the compound after consumption.

Processing and cooking tomatoes can significantly increase lycopene’s bioavailability. The heat from cooking helps break down the tomato’s tough cell walls, releasing the lycopene and making it more accessible. This process also helps convert it into a form that is more easily absorbed by the body. As a result, products like tomato paste, sauce, and juice can offer a more bioavailable source of lycopene than fresh tomatoes.

Consuming tomatoes with a source of dietary fat is another effective strategy for boosting lycopene absorption. Lycopene is a fat-soluble compound, meaning it dissolves in fats. When you eat tomatoes with a healthy fat like olive oil, the fat acts as a carrier molecule, helping to transport the lycopene into the bloodstream. This is why a dish like pasta with tomato sauce and olive oil can be an effective way to get this nutrient.
