A síndrome metabólica (SM) aumenta o risco de eventos cardiovasculares e o consumo adequado de frutas, verduras e legumes (FVL) está relacionado a sua prevenção. Objetivo: Identificar o consumo de FVL e sua relação com a SM e seus componentes em amostra populacional adulta. Estudo prospectivo de corte transversal com 636 indivíduos adultos, no período de 2004 a 2008. Foram realizadas avaliações antropométrica, clínica, dietética e bioquímica com todos participantes. A SM foi classificada pelo NCEP ATP-III, modificada para a glicose >100mg/dl. A regressão logística foi utilizada para verificar a razão de chance entre o consumo de FVL com a SM e seus componentes, e o nível de significância adotado foi de 5%. O consumo de frutas adequado se mostrou protetor para obesidade abdominal (OR: 0,77; IC: 0,38-0,93), hipertrigliceridemia (OR: 0,76; IC: 0,35-0,96) e presença de SM (OR: 0,78; IC: 0,39-0,96), e o consumo adequado de FVL apresentou efeito protetor para a presença de SM (OR: 0,79; IC: 0,41-0,95). A análise isolada do consumo adequado de verduras e legumes não mostrou efeitos de proteção/risco para a presença de SM e de seus componentes. O consumo adequado de FVL apresentou efeito protetor para a presença de SM e o consumo adequado de frutas exerceu efeito protetor tanto para a presença de SM e como de seus componentes.

This article reviews the metabolism of fructose and sorbitol, their main clinical indications and the consequences of inadequate use. Fructose, an important carbohydrate in the diet, is present mostly in fruits and vegetables; it can also be synthesized from glucose in the organism, through the sorbitol. Fructose is known for its metabolism's inherent errors, whose clinical manifestations are potentially serious, as well as for its use as a glucose substitute in the diabetic patients' diet, due to its metabolism not being dependent from insulin. In the last years, especially in developed countries, the consumption of fructose has increased considerably, due to its use as a sweetener in industrialized foods. However, adverse side-effects may occur with the excessive ingestion of fructose, such as the increase in blood's triglycerides and cholesterol. Therefore, to know which are the patients' normal blood levels is quite important for establishing the safe amount of fructose to be prescribed, as well as for allowing the screening of metabolism diseases associated with fructose.

The grape is considered a major source of phenolic compounds when compared to other fruits and vegetables, however, there are many cultivars with distinct characteristics directly linked to phenolic profile. Thus, the present study aimed to identify and quantify, for the first time and in detail, the phenolic compounds present in the skin, flesh and seeds of BRS Violeta grape berry using combination of SPE methodologies and analytical HPLC-DAD-ESI-MS/MS. The study was extended to the different berry parts and the most important grape and wine phenolic families, and has revealed interesting features. Violeta grape has a very thick skin (46% of grape weight) that accumulated the most of grape phenolic compounds: great amount of anthocyanins (3930. mg/kg, as malvidin 3,5-diglucoside), together with also important amounts of flavonols (150. mg/kg, as quercetin 3-glucoside), hydroxycinnamic acid derivatives (HCAD; 120. mg/kg, as caftaric acid), and proanthocyanidins (670. mg/kg, as (+)-catechin); in contrast, it seems to be a low resveratrol producer. Violeta grape seeds accounted for similar proportions of low molecular weight flavan-3-ols (mainly monomers; 345. mg/kg, as (+)-catechin) and proanthocyanidins (480. mg/kg, as (+)-catechin). Violeta grape is a teinturier cultivar, but it only contained traces of anthocyanins and low amounts of all the other phenolic types in its red-colored flesh. The anthocyanin composition of Violeta grape was dominated by anthocyanidin 3,5-diglucosides (90%). Within flavonols, myricetin-type predominated and kaempferol-type was missing. In addition to expected hydroxycinnamoyl-tartaric acids, several isomeric esters of caffeic and p-coumaric acids with hexoses were tentatively identified, accounting for relevant proportions within the pool of HCAD. Although pending of further confirmation over successive vintages, the aforementioned results suggest that BRS Violeta grape cultivar could be considered an interesting candidate for the elaboration of highly colored and antioxidant-rich grape juices and wines. © 2013 Elsevier Ltd.
