Correlation between canned tomatoes and cancer prevention

Correlation between canned tomatoes and cancer prevention

There are a number of health benefits that come from the regular consumption of tomatoes and tomato products. Here’s what science has to say about the correlation between canned tomatoes and cancer prevention.

Cancer is a global health concern, and a leading cause of death worldwide. Billions of dollars are spent annually on cancer research, and a significant number of those studies focus on the effects of certain compounds found in food and their cancer prevention properties. The bioactive compounds of plant based foods have been thoroughly examined, with an emphasis on carotenoids and phenolic compounds.

One of the most potent antioxidants out there is called lycopene, which is the powerful pigment responsible for giving tomatoes their bright red color. It can also neutralize reactive oxidative species, and prevent damage to our cell’s DNA. According to several scientific studies, people who consume more tomato products have a reduced risk of developing prostate cancer, likely due to the powerful combination of lycopene, vitamin A, and vitamin C that occurs naturally in tomatoes. Along with being an antioxidant, lycopene can promote cancer cell apoptosis (ie. death), and interfere with cell signaling pathways to prevent cancerous cells from reproducing.

While fresh tomatoes are relatively high in lycopene, the compound becomes more bioavailable as tomatoes are cooked, meaning your body can absorb more and take advantage of its anti-cancer properties. Why is this? Heat changes the structure of the lycopene molecule, making it easier for the body to take in, and helps break down cell walls, which frees lycopene and allows it to be absorbed.  A recent study found that men who ate cooked tomatoes five to six times per week had a 28% decreased risk of developing prostate cancer versus those who didn’t. Eating tomato products such as tomato sauce, tomato juice, tomato soup, canned tomatoes, tomato paste, and salsa is a great way to ensure you are getting in plenty of cancer-fighting lycopene.

To get the most out of your canned tomato products, try adding a little bit of oil to your tomatoes, as this can boost your ability to absorb lycopene even more. This is because lycopene is a fat-soluble compound, and the fat in oil helps lycopene get broken down to a form usable by the body. A serving of whole wheat pasta with tomato sauce and a side salad with olive oil and vinegar is the perfect prostate-cancer-preventing meal!

Is fresh really best? Here’s why canned tomatoes reign supreme.

Is fresh really best? Here’s why canned tomatoes reign supreme.

Is fresh really best? Despite some common misconceptions, canned goods (like tomatoes) can be a more delicious, nutritious, and a more affordable option compared to their fresh counterparts. Here’s why you should consider adding some canned (or jarred) tomatoes to your grocery list.

Many people may be under the belief that while canned foods are convenient, they are lacking in nutrients. But is this thought process really true? Let’s break down the difference between fresh and canned tomatoes to see which one comes out on top.

Fresh Tomatoes

Tomatoes pack many beneficial health compounds–such as fiber and vitamins A and C–that are important for a healthy heart, as well as eyes, skin, and gums. Tomatoes also contain a powerful antioxidant and pigment called lycopene, which lends tomatoes their bright red color and contributes to heart health and cancer prevention.

While they may be available year-round, fresh tomatoes are often shipped over long distances in the winter or grown in heated greenhouses. It can take up to two weeks from field to fork to get fresh tomatoes when they are out of season, and they certainly won’t taste as good. While fresh tomatoes can add a flavorful bite to many dishes, they are best when they are in season. However, if you don’t have a garden and have to purchase fresh tomatoes, you might want to reserve them for dishes in which this texture really makes a difference (such as salads and sandwiches), as there’s no need to use fresh in dishes that feature cooked tomatoes.

Canned Tomatoes

Canned tomatoes are harvested at their flavor and nutrition peak and canned within just a few hours. Plus, they are quite affordable, meaning that this is a budget-friendly, easy, and convenient option for you and your family.

In addition to the affordability of canned tomatoes, they are rich in vitamins and minerals your body needs to function properly and can help boost energy and reduce the risk of certain diseases. In fact, studies have shown that canned tomatoes are even more nutrient-rich and environmentally-friendly than fresh tomatoes. And, as people continue to cook from the comfort of their own homes, canned tomatoes have grown in popularity thanks to their ease of use, high nutrition content, and a variety of forms (like tomato sauce, tomato paste, marinara sauce, salsa, and diced, stewed and whole tomatoes). Since fresh tomatoes can cost more–especially during the fall/winter/spring–you’re better off using canned/jarred tomato products for dishes in which the texture of fresh isn’t important, such as pasta dishes, pizza, lasagnas, curry, soups, stews, and casseroles and you want that PEAK of season flavor and nutrition.

What’s the verdict?

While fresh tomatoes can be eaten throughout the year, they are at their peak during summer; as such, it can be challenging to enjoy their ripeness during fall, winter, and spring. Conversely, canned tomatoes can be enjoyed all year round as an affordable, nutritious option that consistently delivers those delicious summer flavors whenever you need them.

    Toasted Ravioli with Vodka Dipping Sauce

    Toasted Ravioli with Vodka Dipping Sauce

    Toasted ravioli is a versatile dish that can be enjoyed as an appetizer, side dish, or the main course. Whip up this decadent and creamy Vodka Dipping Sauce, and it will taste just like going to a fancy restaurant, but from the comfort of your own home! 

    As with most Italian sauces, the main flavor comes from tomatoes. Not only do tomatoes offer sweetness and acidity to this recipe, they have important health benefits. Cooked tomato products (found in canned tomato products) contain an ingredient called lycopene, which is a powerful antioxidant that has been proven to protect the body against many chronic diseases. Similar to most nutrients, it’s more natural to obtain lycopene from foods rather than supplements. In order to achieve maximum health benefits associated with lycopene, it is recommended to consume tomato products with a heart healthy fat, such as olive oil or avocado. That’s why we recommend enjoying lycopene and its health benefits through delicious foods such as this recipe. So, what are you waiting for? Enjoy some canned tomato products today with this tasty recipe for Toasted Ravioli!

    Crockpot Chicken Burrito Bowl

    When it comes to weeknights, we are always looking for new quick, easy, and family friendly meals. This Chicken Burrito Bowl checks all of the boxes, and is especially great for those families that have a picky eater or have different dietary restrictions. It’s easily customizable to fit your needs and preferences, while still being nutritious!

    What makes this meal so delicious (and nutritious) is the combination of lean protein and canned tomatoes. The chicken add a heafy dose of protein, while the canned tomatoes provide a plethora of antioxidants (such as lycopene) that play an integral role in the reduction of certain types of diseases and cancers. In fact, numerous studies have linked lycopene consumption with prostate cancer protection. While lycopene is present in other fruits such as watermelon and pink grapefruit, tomatoes, which are the second most consumed vegetable (second to potatoes) in the U.S., account for more than 85% of the lycopene in the American diet. Interestingly, cooked tomato products—as in processed tomatoes, including tomato sauce and canned tomatoes—may hold particular significance. The lycopene from cooked and processed tomatoes is more bioavailable than that of fresh tomatoes. Heating or processing breaks down the tomato cell matrix and promotes isomerization of lycopene from all-trans isomers to the more bioavailable form of cis-isomers. Research shows that single daily servings of processed tomato products produce significant increases of lycopene concentrations in blood and buccal mucosal cells in healthy adults.

    So, what are you waiting for? Try out this Chicken Burrito Bowl for a recipe that’s easy, delicious, and sure to be a family favorite!
