Tomatoes
Description:
In the area of food and phytonutrient research, nothing has been hotter in the last several years than studies on the lycopene in tomatoes. This carotenoid found in tomatoes (and everything made from them) has been extensively studied for its antioxidant and cancer-preventing properties. The antioxidant function of lycopene-its ability to help protect cells and other structures in the body from oxygen damage-has been linked in human research to the protection of DNA (our genetic material) inside of white blood cells.
Prevention of heart disease has been shown to be another antioxidant role played by lycopene. In contrast to many other food phytonutrients, whose effects have only been studied in animals, lycopene from tomatoes has been repeatedly studied in humans and found to be protective against a growing list of cancers. These cancers now include colorectal, prostate, breast, endometrial, lung, and pancreatic cancers.
While lycopene may play an important role in tomatoes' health benefits, it seems that it is not the only nutritional star integral for giving this food a red-hot reputation for health promotion; recent research discussed below in the section "Protection Due to Synergy of Tomato's Nutrients, Not Just Lycopene" describes how scientists are finding out that it is the array of nutrients included in tomatoes, including, but not limited to lycopene, that confers it with so much health value. All the while, it's still important to understand the many benefits that lycopene provides.
Turkey
Description:
Turkey is a very good source of protein. A four ounce serving provides 65.1% of the daily value for protein, along with 11.9% of the daily value for saturated fat, about half the amount of saturated fat found in red meat. The structure of the human body is built on protein. We use animal and plant sources of protein for our amino acids and rearrange the nitrogen to make the pattern of amino acids we require.
Turkey is a very good source of the trace mineral, selenium. Selenium is of fundamental importance to human health. It is an essential component of several major metabolic pathways, including thyroid hormone metabolism, antioxidant defense systems, and immune function. Accumulated evidence from prospective studies, intervention trials and studies on animal models of cancer have suggested a strong inverse correlation between selenium intake and cancer incidence.
