Sweet potato (Ipomoea batatas L.) leaves are consumed as vegetables around the world, especially in Southeast Asia. The aim of this study was to investigate the inhibitory effect of sweet potato leaves on low-density lipoprotein oxidation in vitro and in human subjects. We compared the antioxidant activity of 8 kinds of sweet potato leaves. Every sweet potato leaf had high radical scavenging ac...

The study of the structure–activity relationship (SAR) of sweet molecules has been traditionally based on indirect analyses that have led to several models of the receptor active site, consistent with the shape of many conformationally rigid sweeteners—see, for example, Temussi et al. (1991) and the references therein. Most sweeteners are low mol. wt compounds but a few sweet proteins are also ...

OBJECTIVE It has recently been proposed that the peripheral taste organ is one of the targets for leptin. In lean mice, leptin selectively suppresses gustatory neural and behavioral responses to sweet compounds without affecting responses to other taste stimuli, whereas obese diabetic db/db mice with defects in leptin receptor lack this leptin suppression on sweet taste. Here, we further examin...

A single-dose oral toxicity lethal-dose study was conducted to examine the toxicity of capsinoids contained in CH-19 Sweet extract. CH-19 Sweet extract was administered once by gavage to SPF (Crl:CD(SD)) Sprague-Dawley male and female rats at dose levels of 0 (vehicle), 5, 10, or 20 ml/kg of body weight (BW). The concentration of capsinoids in the CH-19 Sweet extract was 71.25 mg/ml; this resul...

Sweet taste transduction involves taste receptor type 1, member 2 (T1R2), taste receptor type 1, member 3 (T1R3), gustducin, and TRPM5. Because knockout (KO) mice lacking T1R3, gustducin's Galpha subunit (Galphagust), or TRPM5 exhibited greatly reduced, but not abolished responses of the chorda tympani (CT) nerve to sweet compounds, it is likely that multiple sweet transduction pathways exist. ...

Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...

We examined the associations of emotional eating and depressive symptoms with the consumption of sweet and non-sweet energy-dense foods and vegetables/fruit, also focusing on the possible interplay between emotional eating and depressive symptoms. The participants were 25-64-year-old Finnish men (n=1679) and women (n=2035) from the FINRISK 2007 Study (DILGOM substudy). The Three-Factor Eating Q...

Sensory properties are greatly involved in the process of satiation. Regarding the nature of sensory signals, an important distinction can be made between sweet and savory taste. It is unclear, however, whether sweet and savory differ in their influence on satiation. Our objective was to investigate the difference between a sweet and savory taste on satiation, independent of palatability, textu...

OBJECTIVES The purpose of this study was to determine the relationship between sweet-liking phenotype and the variation of the gene sequence of the dopaminergic and serotonergic system. METHODS The study recruited 100 probands. The participants were interviewed for addiction (SSAGA-Semi Structured Assessment for the Genetics of Alcoholism) and assessed with the questionnaires: MMSE, Beck Depr...

BACKGROUND Intake of sweet drinks has previously been associated with the development of overweight and obesity among children and adolescents. The present study aimed to assess the consumption pattern of sweet drinks in a population of children and adolescents in Victoria, Australia. METHODS Data on 1,604 children and adolescents (4-18 years) from the comparison groups of two quasi-experimen...
