Lycopene is known to decrease cardiovascular risks. The objective of this study was to investigate the molecular mechanisms of tomato paste containing approximately 0.1% lycopene in regulating lipid metabolism and oxidation. Hamsters fed 3% or 9% tomato paste containing 0.2% cholesterol were subjected to total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), and ...

Lycopene bioavailability from a single dose of fresh tomatoes or tomato paste (23 mg lycopene) ingested together with 15 g corn oil was compared by analyzing carotenoid concentrations in the chylomicron fraction. The lycopene isomer pattern was the same in both fresh tomatoes and tomato paste. The triacylglycerol response in chylomicrons was not significantly different after both treatments. In...

Prior investigations on the beneficial effect of dietary processed tomato products and lycopene on prostate cancer risk suggested that lycopene may require the presence of other constituents to exert its chemopreventive potential. We investigated whether ketosamines, a group of carbohydrate derivatives present in dehydrated tomato products, may interact with lycopene against prostate tumorigene...

conclusions decreases of tc, ldl and tg may be related to tomato antioxidant effect. this course in human required more investigations. results results showed that in chol group, all lipids increased significantly (p < 0.05) except hdl compared to the control group. tomato and tomato paste supplementation decreased tc, ldl and tg concentration significantly (p < 0.05) compared to chol group. to...

The consumption of tomatoes and tomato products has been associated with a reduced risk of prostate cancer. We observed a decrease of 10.77% in prostate-specific antigen (PSA) levels in patients with benign prostate hyperplasia who were submitted to daily ingestion of tomato paste. This was an experimental rather than a controlled study with a sample of 43 men ranging in age from 45 to 75 years...

BACKGROUND Hypercholesterolemia is one of the risk factors of cardiovascular diseases. Increased blood cholesterol affects general health and increases mortality due to cardiovascular disease. Poor nutrition increases LDL cholesterol and decreases LDL receptor activities in the liver. Scientists have shown that consumption of antioxidants can reduce hypercholesterolemia and proved benefits of f...

agriculture (mechanization), food industry and environment are the concepts that cannot be surveyed separately (because of their interaction). present research aimed to study tomato paste production by applying life cycle assessment. two functional unit of kg co2-eq/ kg tomato and kg co2-eq / kg paste was used. data were collected from one paste factory in alborz province and open-field tomato ...
