Tomato Products – Preserved and Precious

This post is sponsored by the Tomato Products Wellness Council and was written by Sharon Palmer, RD.

When you’re scouring the supermarket for healthy fruits and vegetables, you usually start in the produce section.  Sure enough, it’s the best place to find healthy, whole fruits and vegetables, packed with vitamins, minerals, fiber and phytochemicals, plant compounds packed with health protective compounds.  But it’s not the only place to find nutritious, delicious vegetables—don’t forget to check out the canned food aisle for canned tomato products, such as canned tomatoes, tomato sauce, and tomato paste.  These vegetables are every bit as nutritious—and maybe even more so—than their fresh brethren.

Unlike fresh tomatoes, which are often picked before they’re ripe and shipped for long distances, preserved tomatoes are harvested ripe and delicious, and canned within hours of picking.  That’s why they are so good in some of your favorite American dishes, such as spaghetti, lasagna, tacos, chili, and tomato soup.  Canned tomato products are so easy; just open the can and pour—no chopping required.  And that’s not all.  Lycopene, the powerful antioxidant found in tomatoes, is even more bioavailable to your body in cooked tomato products, such as in canned tomatoes.  Canned tomatoes provide 11.8 milligram of lycopene per half cup, compared with 3.7 milligrams found in one medium fresh tomato.

Preserved tomato products are also a great bargain.  A recent study presented at the Experimental Biology 2012 annual meeting put the common misconception that canned products are often inferior to their fresh counterparts to rest.  Researchers examined the nutrient properties of canned and fresh varieties of common foods, and the findings were very interesting, especially in regards to tomatoes.  When it comes to getting your dietary fiber, it’s 60% more expensive to get the same amount from fresh tomatoes as opposed to canned.

Nearly 650 studies have been conducted on the health benefits of consuming more tomato products.  Here are some of the main reasons you should include these in your diet at least a few times per week.

  • A Nutritional Powerhouse. Tomato products are loaded with essential vitamins, minerals, and fiber—all in a neat low-fat, low-calorie package. One cup of canned tomatoes contains 41 calories, 0 grams fat, 2.4 grams fiber, 2 grams protein, 37% Daily Value (DV) vitamin C, 8% DV vitamin A, 9% DV vitamin K, 13% DV vitamin B6, 13% DV iron, 13% DV potassium, and 9% DV manganese.
  • Lycopene Bonus.  Tomato products are rich in the powerful antioxidant group, carotenoids (including lycopene), which have been shown to inactivate free radicals, protect against cancer, and slow development of atherosclerosis. Tomato products are responsible for more than 80% of the lycopene in the U.S. diet, and research suggests that lycopene may be a big factor behind the health-protective effects of tomato products.
  • Fighting Inflammation.  Tomato products may help cool down inflammation, which is becoming more widely understood as a root in many chronic diseases.  In two studies funded by TPWC, scientists discovered that people who eat a high-tomato diet have lower levels of inflammatory markers.
  • Protect Against Oxidative Stress.  Eating foods rich in antioxidant vitamins and carotenoids, such as tomato products, is linked with reducing oxidative stress—key in the development of cardiovascular disease.
  • Prostate Cancer Defense.  Growing evidence links consumption of tomato products with protection against prostate cancer.  The NIH recently funded a groundbreaking study to trace how tomato lycopene works in the human body to protect against this disease.
  • Heart-health Benefits.  Regular intake of tomato products has been consistently associated with lower rates of cardiovascular disease.  In a study of nearly 40,000 middle-aged and older women, scientists discovered that higher levels of tomato-based products in the diet were linked with lower rates of cardiovascular disease.

    I’ve also read that canned tomatoes are rich in BPAs, so it is better to find tomatoes packaged in boxes or glass. Some BPA-free commercial brands are available in the USA, but the easiest way to find tomatoes canned in glass is to can them yourself — they are easy to can. Maybe consumer awareness and pressure will persuade food companies to stop putting tomatoes into BPA-lined packages.

    Sharon – low-sodium tomatoes, and skip the added salt. 610 mg of Na in a 130 kcal serving? Ugh.
    Fooducators — what the $%#& is a “sponsored” post? Are we reading an ad? Tomatoes are fine, but where will you draw the line?

      610 mg of sodium is for the entire recipe. I recommend looking for unsalted tomato products.

  • Heather

    Simply delicious! I try and can my own fresh garden tomatoes to avoid chemicals and salt.

    Even cans that claim they are BPA free contain some BPAs. Also even if they are legitimately BPA free, watch out for BPS. It is more toxic than BPA, and is not reported. The acids in tomatoes cause BPA cans to leach into the tomatoes, regardless of the type of tomato product you are getting I.e. paste, sauce, stewed, etc. Another note, if the tomatoes are not organic, there is a good chance it is GMO tomatoes.

    • Fooducate

      GMO tomatoes have not been approved for sale in the US.

        The first GMO food to hit our dinner tables was the flavr savr tomato. Please disclose where it says it is not approved for sale in the US? Tomatoes are among the top 10 GMO produced foods, approved by the FDA in 1994. Although production of the flavr savr tomato stopped in 1997, it is still on the FDA approved list
