Breeders can enhance nutritional value using inexpensive colorimeter method Carotenoids, the family of yellow to red pigments responsible for the striking orange hues of pumpkins and the familiar red color of vine-ripe tomatoes, play an important role in human health by acting as sources of provitamin A or as protective antioxidants. Pumpkins and squash, available in a wide range of white, yellow, and orange colors, are excellent sources of dietary carotenoids, particularly lutein,...

Report by Nutrilite Health Institute is first major analysis of NHANES fruit and vegetable consumption by color While it is a well-known fact that most Americans do not eat enough fruits and vegetables, a new report shows the color of fruits and veggies eaten can be as important as the quantity. Eight in 10 Americans are missing out on the health benefits of a diet rich in colorful fruits and vegetables, resulting in a phytonutrient gap with potential health consequences, according to...

Antioxidant supplements do not appear to increase risk of melanoma, as previously suspected, according to a new report. Findings in a recent randomized trial of antioxidants for cancer prevention seemed to suggest daily supplementation with nutritionally appropriate doses of vitamins C and E, beta-carotene, selenium and zinc increased the risk of melanoma in women four-fold. Because an estimated 48 to 55 percent of U.S. adults use vitamin or mineral supplements regularly, the potential for...

Strigolactones are plant hormones, which were first discovered in crop plants during the infection with the parasitic plant "Striga". Only plants which produce strigolactones were infected with the parasite resulting in a significant reduction of vigor. Moreover, this signaling pathway plays also an important role in plants to initiate symbiotic interactions with mycorrhiza fungi to enhance the absorption of nutrients from the soil. The third hormonal effect known so far is an influence on...

Golden Rice is a variety of Oryza sativa rice produced  through genetic engineering to biosynthesize beta-carotene, a precursor of vitamin A, in the edible parts of the rice. The research was conducted with the goal of producing a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A, a deficiency which is estimated to kill 670,000 children under five years old each year. Golden rice is different from its parental strain by the addition of three...
