Chia seeds (CS) and sprouts are rich in bioactive compounds. This study aimed to assess the effects of germination and chemical elicitation (salicylic acid [SA]; hydrogen peroxide [H O ]) on proximate chemical, total phenolics compounds (TPC), non-extractable proanthocyanidins (NEPA), and carotenoids content of chia sprouts; besides, the effects of their supplementation on obesity-associated complications in rats fed with high-fat and fructose diet (HFFD) were evaluated. Protein, carbohydrate, TPC, NEPA, and carotenoids content were higher in sprouts than CS; elicitation enhanced TPC and carotenoids compared to non-elicited (NE) sprouts. CS, NE, and elicited chia sprouts ameliorated insulin resistance and dyslipidemia at the same level in HFFD-fed rats. NE and SA-chia sprouts exerted the biggest reduction in hepatic triglycerides, which could be partially related to inhibition of pancreatic lipase activity. In addition, SA elicitation induced the greatest effect on insulin levels and corporal weight. CS and their sprouts decreased obesity and its complication, mainly SA-elicited sprouts. PRACTICAL APPLICATIONS: The growing epidemic of non-communicable diseases such as diabetes and obesity has led to the search for prevention and treatment through lifestyle changes, including the consumption of foods rich in bioactive compounds, such as seeds and their sprouts. Since sprouts contain higher concentrations of bioactive compounds and nutrients than seed, germination is a natural alternative to produce ready-to-eat functional foods. Chemical elicitation is a strategy to increase even more the bioactivity of sprouts. CS has been recognized for its beneficial health effects ameliorating dyslipidemia and insulin resistance. This study demonstrates that elicitation, with SA and H O , during germination of CS, increases the nutrient and phytochemical content of sprouts, with beneficial effects on body weight gain, insulin resistance, dyslipidemia, and prevention of NAFLD progression in diet-induced obese rats. Therefore, chia sprouts, natural and elicited, may be used as potential nutraceutical foods for the prevention and treatment of obesity and its complications.
奇亚籽(CS)和芽菜富含生物活性化合物。本研究旨在评估发芽和化学诱导(水杨酸[SA];过氧化氢[H₂O₂])对奇亚芽菜的近似化学、总酚化合物(TPC)、非提取原花青素(NEPA)和类胡萝卜素含量的影响;此外,还评估了它们对高脂肪和果糖饮食(HFFD)喂养大鼠肥胖相关并发症的补充作用。芽菜中的蛋白质、碳水化合物、TPC、NEPA 和类胡萝卜素含量高于 CS;与未诱导(NE)芽菜相比,诱导提高了 TPC 和类胡萝卜素含量。CS、NE 和诱导的奇亚芽菜在 HFFD 喂养的大鼠中改善了胰岛素抵抗和血脂异常。NE 和 SA-奇亚芽菜对肝甘油三酯的降低作用最大,这可能与抑制胰脂肪酶活性有关。此外,SA 诱导对胰岛素水平和体重的影响最大。CS 及其芽菜降低了肥胖及其并发症,主要是 SA 诱导的芽菜。实际应用:糖尿病和肥胖等非传染性疾病的流行不断增加,导致人们通过生活方式的改变来寻找预防和治疗方法,包括食用富含生物活性化合物的食物,如种子及其芽菜。由于芽菜比种子含有更高浓度的生物活性化合物和营养物质,因此发芽是生产即食功能性食品的自然选择。化学诱导是增加芽菜生物活性的一种策略。CS 因其改善血脂异常和胰岛素抵抗的有益健康作用而受到认可。本研究表明,在 CS 的发芽过程中,用 SA 和 H₂O₂ 进行诱导,增加了芽菜的营养和植物化学物质含量,对体重增加、胰岛素抵抗、血脂异常和预防饮食诱导肥胖大鼠的非酒精性脂肪性肝病(NAFLD)进展有有益作用。因此,天然和诱导的奇亚芽菜可作为预防和治疗肥胖及其并发症的潜在营养食品。
