Lycopene

Summer reason is also known as the BBQ season for many people, especially in Canada. We love to have tomatoes on the burgers, salad and use them for appetizers as well. However, did you know that tomatoes are a good source of lycopene, which is a bone-protective antioxident.

Studies show that 30mg of lycopene a day significantly reduced both oxidative damage and bone breakdown. Other studies showed that as little as 12.64 mg lycopene a day lowered fracture risk. So you can double or even triple the tomato slices on your sandwich next time.

Tomato products and lycopene content

Tomato product               Serving Size          Lycopene content

Tomato paste                          1cup                             75.4 mg

Tomato puree, canned          1 cup                            54.38 mg

Tomato sauce, canned           1 cup                           34.25 mg

Pasta sauce, canned               1 cup                           31.66 mg

Vegetable juice cocktail         1 cup                           23.38 mg

Tomato juice                            1 cup                          21.91 mg

Tomato soup                            1 cup                          13.05 to 22 mg

Tomato, raw                             1 cup                          4.6 mg

The chart shows that a cup of tomato paste contains much more lycopene than a cup of raw tomato. Studies show that the lycopene content and its antioxident level increase substantially when the tomatoes are cooked. The take home point is to eat as much varieties of food as possible, some raw, some lightly steamed and some cooked. You will get all the benefits you need from food.

If you are sensitive to tomatoes, you can also enjoy other red fruits and vegetables such as watermelon, gac (a Vietnamese fruit) or pink grapefruit.
