A Study of Tomato Products and Disease Risk

This study will take three weeks at most, and require one initial screening visit lasting approximately 45 minutes and two study visits each lasting approximately 6 - 8 hours. The investigators are looking for healthy, non-smoking male and female volunteers between the ages of 18 - 65, with no medical history of diabetics, heart, lung, kidney, stomach, or liver disease. The initial screening visit will determine subject' eligibility through height, weight and waist circumference measurements, blood glucose (finger prick) test and a fasting screening blood draw. There will be no compensation for the screening visit, other than transportation costs. If subject qualify, subject will continue to the two study visits. Each visit will require subject to have blood drawn several times during subject' study visit (total amount of blood equal to approximately 1 ½ tablespoons). To make this process more tolerable, a registered nurse will place a catheter (similar to what happens when you give blood) into subject's vein for ease in drawing blood. After the catheter placement and the first blood draw, subject will be asked to eat the test meal (tomato or non-tomato meal) and then subject will continue to have blood taken at specific time points for the next 6 hours. The investigators will also do an ultrasound on subject's arm to measure blood flow both before eating and midway through the 6 - hour study visit. The investigators will ask that subject not consume tomatoes or tomato products during the course of the study and record all food and beverages consumed on certain days.
