Associations Between Polyphenol Intake, Cardiometabolic Risk Factors and Metabolic Syndrome in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Background: Fruit- and vegetable-rich diets may protect against metabolic syndrome (MetS), partly due to their high polyphenol content.

Objectives: This study examined the association between dietary polyphenol intake, MetS risk, and cardiometabolic factors in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods: A total of 6387 participants (mean age 49.

Changes in flavonoid and carotenoid profiles alter volatile organic compounds in purple and orange cherry tomatoes obtained by allele introgression.

Background: Tomatoes are an important source of human health-promoting compounds, and efforts have been made to enhance their nutritional quality through conventional plant breeding or biotechnology. This study assessed the composition of volatile compounds, phenolics and carotenoids in two allele-introgressed tomato lines, an anthocyanin-rich purple tomato and a β-carotene-rich orange tomato, as well as a red tomato.

Results: The purple tomato peel accumulated a high amount of anthocyanins, mainly petunidin 3-(p-coumaroyl)-rutinoside-5-glucoside, responsible for the purple color, and other flavonoids such as rutin and kaempferol.

Antioxidant status in rats after long-term intake of anthocyanins and ellagitannins from blackberries.

Background: This study reported the effects of the daily intake of anthocyanins and ellagitannins (ET) extracted from blackberries on the markers for oxidative status in healthy rats.

Results: The phenolic compounds were administered from three different extracts: an aqueous extract of blackberry (BJ) and its two derived fractions: anthocyanin-enriched (AF) and ET-enriched (EF) fractions. After 35 days’ administration, the AF and EF extracts significantly reduced thiobarbituric acid reactive substance levels and increased glutathione levels in the liver,kidney and brain.
