Lycopene from heat-induced cis-isomer-rich tomato sauce is more bioavailable than from all-trans-rich tomato sauce in human subjects - Volume 98 Issue 1 - Nuray Z. Unlu, Torsten Bohn, David M. Francis, Haikady N. Nagaraja, Steven K. Clinton, Steven J. Schwartz The real draw of tomato juice is lycopene—an antioxidant found in ruby and orange foods that may help lower risk of stroke, prostate cancer and metabolic diseases. Mean serum PSA concentrations decreased by 17.5% (P < 0.002) and leukocyte 8OHdG decreased by 21.3% (P < 0.005) after tomato sauce consumption. Lycopene, a powerful antioxidant, is found abundant in tomatoes and tomato products. Eat fresh tomatoes with olive oil, an ideal fat for absorption. four servings of tomato sauce per week was associated with about a 35% risk reduction of total prostate cancer and a 50% reduction of advanced (extraprostatic) prostate cancer.

Whole crushed or stewed tomatoes can be used to make a homemade pasta sauce. Simply cook the pasta according to manufacturer’s instruction. Lycopene is relatively resistant to heat-induced geometrical isomerization in tomato processing.7 Processed tomato products are a better source of lycopene than fresh tomatoes,8 with lycopene more bioavailable.9 In addition, human uptake of lycopene is greater from heat-processed tomato juice than from unprocessed tomato juice.10 Tomato sauce and ketchup contain 33 to 68 mg of lycopene … Tomato products diluted with deionized water and analyzed for lycopene content Product name Company # of lots Tested Concentration (%)a Vegetable juice A 2 33 Spicy hot vegetable juice A 1 33 Tomato juice A 2 33 Tomato soup A 2 33 Tomato sauce B 2 33 Tomato sauce C 1 33 Tomato sauce D 1 33 Tomato paste C 1 25 Diced Tomatoes (peeled) B 1 33 Lycopene, the predominant carotenoid in tomatoes, exhibits the highest antioxidant activity and singlet oxygen quenching ability of all dietary carotenoids.

Want to use it in a meal plan? There is evidence that dietary fat may help increase the absorption of carotenoids, including lycopene. These items include tomato and spaghetti sauce, tomato soup, salsa, ketchup, and tomato paste. Tomato soup, sauce and juice consumption significantly increased plasma lycopene concentration from 66%, 71%, and 59%, respectively, while the controls consuming the lycopene-restricted diet showed a decline in plasma lycopene concentration by 24%. Posted October 11th, 2012 at 12:48 pm Lycopene can be found in every tomato products which are easily available in the market. In fact, research shows that 100 mg of raw tomato has 2,573 mcg of lycopene while 100 mg of tomato sauce has 15,152 mcg. “Lycopene is trapped in the cell wall of the vegetable,” Scherban says. A second study shows that lycopene from tomato paste is better absorbed by the body than lycopene from fresh tomatoes, suggesting that processed tomato products-such as tomato paste, tomato sauce and ketchup-are a better source of this antioxidant. A serving of fresh tomatoes contains between 4 mg and 10 mg of lycopene, while one cup (240 mL) of tomato juice provides about 20 mg. the form of tomato product you consume as your source of lycopene determines whether that lycopene ends up in your blood and plasma. tomato sauce along side with Lycopene supplement might be the best way for Lycopene consumption Processed tomato products such as pasteurized tomato juice, soup, sauce, and ketchup contain a higher concentration of bioavailable lycopene compared to raw tomatoes.

Tomatoes, and in particular processed tomato products like tomato sauce, tomato soup and ketchup, are by far the biggest sources of lycopene in the American diet. High performance liquid chromatography was employed for detecting lycopene and 5-hydroxymethylfurfural (HMF). In vitro and clinical studies of osteoblast cells found the intake of a lycopene-rich tomato sauce (5 mg and 10 mg) in 39 postmenopausal women resulted in no significant bone density loss with the treatment and better bone turnover results compared to those in the non-tomato sauce control group, showing that tomato sauce can be used to lower risk of bone loss and to prevent osteoporosis.

Tip: this sauce merges wonderfully with macaroni or pasta. For instance, in a raw tomato, you may get as little as 8.8 mcg/g of lycopene, whereas in tomato sauce, you may get as much as 131 mcg/g. Four levels of lycopene in the culture medium were investigated (0.1, 0.5, 1, and 5 μM), which correspond to 0.1, 0.5, 1 and 5 nmol/mL, to encompass the average lycopene concentration in the serum of our subjects (1.26 μM) and in prostate tissue (0.82 nmol/g) after tomato sauce intervention. Lycopene in Foods According to Harvard Medical School, one slice of raw tomato contains approximately 515 micrograms lycopene, while 2 tablespoons of tomato paste contains 13,800 micrograms of lycopene. According to MayoClinic.com, most clinical studies have focused on the amount of lycopene-containing foods that participants ate rather than on the specific quantities of lycopene … Xiang-Dong Wang: We demonstrated for the first time that tomato powder rich in lycopene can effectively reduce fatty liver disease, inflammation, and liver cancer development promoted by the high-fat diet the mice were consuming.

Powdering and freeze drying tend to decrease the amount of lycopene and makes it very unstable, whereas freezing and heat processing stabilizes the lycopene. (Don’t try this if you are living with heart failure or need to limit potassium.) Processing of tomatoes increases the biovailability of lycopene. Ripe tomato peels are the richest source of lycopene, but the use of conventional solvent extraction methods without pretreatment of the plant material results in very poor recovery. Adherence to the daily consumption of tomato-based entrees was 81.6% of the intended dose, and serum and prostate lycopene concentrations increased 1.97- and 2.92-fold (P < 0.001), respectively. Salt can be an issue, especially when lycopene comes from prepared products like tomato juice or canned tomato sauce.
