Blood-pressure reading of 140/90 mmHg (systolic/diastolic pressure) are typically regarded as having high blood pressure as defined in the most recent guidelines. From a physiological perspective, the regulation of blood pressure is a complicated process involving different biological systems and a number of feedback systems, including the nervous system, hormones, control of body fluid and … Continued
Our previous double-blinded, placebo-controlled cross-over study indicated that a nutritional supplement named lycopene-rich tomato nutrient complex (TNC) can protect from UVA1-induced (340–400 nm) and UVA- (320–400 nm)/UVB-induced (280–320 nm) upregulation of molecular markers associated with oxidative stress, inflammation, and ageing.
Oral carotenoids and polyphenols have been suggested to induce photo-protective effects. The aim of the study was to test whether the combination of carotenoids and polyphenols produce greater protective effects from UV-induced damage to skin cells. Such damage is characterized by inflammation and oxidative stress; thus, the photo-protective effect can be partially explained by modulating … Continued
Carotenoids are suitable photoprotectants, and beta-carotene supplements are used for protection against ultraviolet (UV) light-induced erythema. Protective effects are also observed when carotenoids are provided with the diet. Here, we investigated the photoprotective effects of synthetic lycopene in comparison with a tomato extract (Lyc-o-Mato) and a drink containing solubilized Lyc-o-Mato (Lyc-o-Guard-Drink). With these different sources, … Continued
Increasing evidence suggests photoprotection by oral supplementation with β-carotene and lycopene.
Epidemiological studies have established that a low serum concentration of carotenoids was associated with risk of Age-Related Macular Degeneration (ARMD). The aim of this study was to determine carotenoid levels in serum and in different lipoprotein fractions in patients diagnosed for ARMD and in matched control group.
