Lipid oxidation products (LOPs) are widely present in many lipid- containing foods. They usually enter the gastrointestinal tract from dietary sources and/or are produced in vivo. Part of LOPs were absorbed into the blood and transported into tissues. A growing bulk of evidence suggests that LOPs, mainly reactive aldehydes and oxysterols, are potentially involved in the pathogenesis of many chronic diseases, such as atherosclerosis, Alzheimer’s disease, and inflammatory bowel disease. This review summarizes the current knowledge of the adverse effects, cytotoxicity, and the main mechanisms of LOPs involvement in humans and animals.
脂质氧化产物(LOPs)广泛存在于许多含脂食品中。它们通常从饮食来源进入胃肠道和/或在体内产生。部分LOPs被血液吸收并转运到组织中。越来越多的证据表明,LOPs,主要是活性醛和氧化甾醇,可能参与许多慢性疾病的发病机制,如动脉粥样硬化、阿尔茨海默病和炎症性肠病。本文综述了目前对LOPs在人类和动物中的不良反应、细胞毒性和主要机制的了解。

Eurycoma longifolia Jack is a plant of the genus Eurycoma in Simaroubaceae. Eurycomanone is one of the main quassinoids of E. longifolia. Unfortunately, these quassinoids exhibit low bioavailability . In the present study, a phospholipid complex (TAF2-PC) was prepared to improve the oral bioavailability of TAF2 (Tongkat Ali Fraction 2). The complexation rate of eurycomanone and phospholipid was used as the index of success in the phospholipid complexes. The effects of reaction solvent, reaction temperature, drug concentration, drug-lipid ratio and reaction time on thecomplexation rate were investigated. Response Surface-Box-Behnken Design Method was performed to optimize the preparation technology and the pharmacokinetics of phospholipid complex of TAF2 were studied in rats. Our results showed that the optimum preparation condition of TAF2-phospholipid complex were as follows: reaction solvent, anhydrous ethanol; reaction time, 1 h; the ratio of TAF2 to phospholipid, 2.28; reaction temperature, 40.85 ℃; TAF2 concentration, 32.66 mg/ml; and complexation rate, 95.04 ± 0.4% (n=3).The results of pharmacokinetic study showed that the relative bioavailability was increased to 209.20% in the TAF2-phospholipid complex-treated rats.Thus,this phospholipid-complex-technique shows potential for enhancing oral bioavailability of poorly absorbed quassinoid-rich E. longifolia extract, TAF2.
长叶芡实(Eurycoma longifolia Jack)是菝葜科芡实属植物。Eurycomanone是长叶草中主要的类西芹类植物之一。不幸的是,这些类星体的生物利用度很低。本研究制备了一种磷脂复合物(TAF2- pc),以提高TAF2(东革阿里分数2)的口服生物利用度,并以芡粉总黄酮与磷脂的络合率作为评价磷脂复合物成功与否的指标。考察了反应溶剂、反应温度、药物浓度、药脂比和反应时间对络合速率的影响。采用响应面-盒- behnken设计法优化制备工艺,并研究TAF2磷脂复合物在大鼠体内的药动学。结果表明,taf2 -磷脂复合物的最佳制备条件为:反应溶剂为无水乙醇;反应时间,1 h;TAF2与磷脂的比值为2.28;反应温度:40.85℃;TAF2浓度,32.66 mg/ml;络合率95.04±0.4% (n=3)。药动学研究结果表明,taf2 -磷脂复合物处理大鼠的相对生物利用度提高至209.20%。因此,这种磷脂复合物技术显示了提高吸收不良的富含番石榴素的长叶提取物TAF2的口服生物利用度的潜力。

Cereals are a staple food in the diets of many populations globally. Besides their nutritive function in food, they are also rich in various groups of bioactive compounds, especially polyphenols. Wheat, rice, barley, rye, oat, maize, millet, sorghum, and other cereal grains present a great variety of phenolic acids, flavonoids, proanthocyanidins, alkylresorcinols, and lignans, which can be affected in many ways by the post-harvest treatments and further processing of these feedstocks. This review discusses up-to-date studies about the effects of common cereal processing techniques on their phenolic composition, biological activities, and bioefficiency. Generally, mild thermal and high-pressure treatments enhance cereals’ phenolic composition by releasing the insoluble-bound fraction, which increases their bioaccessibility. On the other hand, processes involving extreme temperature conditions and removal of the grains’ outer layers may drastically reduce the phenolic content. Therefore, it is imperative to optimize the processing conditions of cereals, so their health-promoting benefits are preserved.
谷物是全球许多人口饮食中的主食。除了在食物中的营养作用外,它们还富含多种生物活性化合物,尤其是多酚类化合物。小麦、水稻、大麦、黑麦、燕麦、玉米、小米、高粱和其他谷物中含有多种酚酸、类黄酮、原花青素、烷基间苯二酚和木脂素,这些物质会受到收获后处理和这些原料的进一步加工的影响。本文综述了常用谷物加工技术对其酚类成分、生物活性和生物效率影响的最新研究。一般来说,温和的热和高压处理通过释放不溶性结合部分来提高谷物的酚成分,从而提高其生物可及性。另一方面,涉及极端温度条件和去除颗粒外层的过程可能会大大降低酚含量。因此,必须优化谷物的加工条件,以保持其促进健康的功效。

Is the gluten-free and casein-free diet efficacious in the treatment of childhood autism spectrum disorder? 无麸质和无酪蛋白饮食对儿童自闭症谱系障碍的治疗有效吗?
Pub Date : 2021-09-30 DOI: 10.31665/jfb.2021.15277

Autism spectrum disorder (ASD) is a set of heterogeneous neurodevelopmental conditions, characterized by early-onset difficulties in social communication as well as repetitive and unusually restricted behaviors and interests. The treatment of ASD is based primarily on psychoeducational and behavioral interventions. Since the effectiveness of available treatments for ASD is limited, many families search for alternative therapies, such as the gluten-free and casein-free (GFCF) diet. Despite the popularity of the GFCF diet as a supplementary treatment in children with ASD, several rigorous evaluations have failed to confirm its effectiveness. The majority of the available studies examining the efficacy of the GFCF diet are seriously flawed and allow no firm conclusions. The available evidence regarding the effectiveness of the GFCF diet in the treatment of childhood ASD is very weak and cannot be considered promising. The GFCF diet should be used only if an allergy or intolerance to nutritional gluten or casein has been established. The identification of a hypothetical diet-related ASD phenotype may help in selecting children who could benefit from a GFCF dietary intervention. An important consideration is that potentially ineffective therapies may imply considerable opportunity costs, with other possibly more effective treatment approaches remaining unutilized.
自闭症谱系障碍(Autism spectrum disorder, ASD)是一组异质性的神经发育障碍,其特征是早发性的社会沟通困难,以及重复和异常限制的行为和兴趣。ASD的治疗主要基于心理教育和行为干预。由于现有治疗方法的有效性有限,许多家庭寻找替代疗法,如无麸质和无酪蛋白(GFCF)饮食。尽管GFCF饮食作为ASD儿童的补充治疗很受欢迎,但几项严格的评估未能证实其有效性。大多数检验GFCF饮食功效的现有研究都存在严重缺陷,没有得出确切的结论。关于GFCF饮食治疗儿童ASD的有效性的现有证据非常薄弱,不能被认为是有希望的。GFCF饮食只有在对营养麸质或酪蛋白过敏或不耐受的情况下才应使用。假设饮食相关的ASD表型的识别可能有助于选择可以从GFCF饮食干预中受益的儿童。一个重要的考虑因素是,潜在无效的治疗方法可能意味着相当大的机会成本,而其他可能更有效的治疗方法仍未得到利用。

The use of vitamin D in depression 维生素D在抑郁症中的应用
Pub Date : 2021-09-30 DOI: 10.31665/jfb.2021.15278

Vitamin D has increasingly been associated with the pathophysiology of mental illness and has been suggested to have beneficial effects on depression in adults. Epidemiological studies concerning vitamin D and depression have found inconsistent results and many have significant methodological limitations. The available evidence suggests that depressed individuals show reduced vitamin D concentrations compared to controls without depression. Despite the available findings suggesting that hypovitaminosis D elevates the risk of depressive mood, the evidence of observational and interventional studies is insufficient to establish causality between low vitamin D levels and the occurrence of depression. The question of whether vitamin D sufficiency has protective efficacy against incident depression or recurrence requires future investigation. In order to examine the therapeutic efficacy of vitamin D, further well-designed, large-scale, long-term intervention trials of vitamin D supplementation in people of different age groups with depressive symptoms, diagnosed depression, postpartum depression or other depressive disorders are warranted. In short, current evidence cannot definitively establish whether vitamin D deficiency is a risk factor in the development of depression or whether vitamin D is effective in the treatment of depression.
维生素D越来越多地与精神疾病的病理生理学联系在一起,并被认为对成年人的抑郁症有有益的影响。关于维生素D和抑郁症的流行病学研究发现了不一致的结果,许多研究在方法上有很大的局限性。现有证据表明,与没有抑郁症的对照组相比,抑郁症患者的维生素D浓度降低。尽管现有的研究结果表明,维生素D缺乏症会增加抑郁情绪的风险,但观察性和干预性研究的证据不足以确定低维生素D水平与抑郁症的发生之间的因果关系。维生素D充足是否对抑郁症的发生或复发有保护作用的问题需要进一步的研究。为了检验维生素D的治疗效果,需要进一步精心设计的、大规模的、长期的干预试验,对不同年龄组的抑郁症状、诊断抑郁症、产后抑郁症或其他抑郁症患者补充维生素D。简而言之,目前的证据不能确定维生素D缺乏是否是抑郁症发展的一个危险因素,或者维生素D是否有效治疗抑郁症。

Healthy food choices by consumers are dictated by several factors but most would like healthy and affordable supply. Of course, traditional foods that are familiar to the consumers and have the appropriate sensory characteristics are most desirable to enhance immunity.  Cultural background of the consumers often dictates their food habits and availability of local foods, driven by economic factors, are important considerations.  Food safety, sustainability and traceability along with regulatory issues are to be considered in order to use the opportunities to address various challenges.
消费者对健康食品的选择是由几个因素决定的,但大多数人喜欢健康和负担得起的食品。当然,消费者所熟悉的、具有适当感官特性的传统食品是增强免疫力的最佳选择。消费者的文化背景往往决定了他们的饮食习惯,在经济因素的驱动下,当地食物的可用性是重要的考虑因素。要考虑食品安全、可持续性和可追溯性以及监管问题,以便利用机遇应对各种挑战。

This study aimed to develop a synbiotic fermented milk with 4% carob powder (CB) as a functional ingredient and using Lactobacillus brevis as a new isolated probiotics strain. Physicochemical characteristics, probiotic viability, total phenolic content (TPC) and antioxidant capacity, antibacterial activity as well as the hypoglycemia activity of carob fermented milk were measured during a cold storage and gastro-intestinal digestion. CB addition to fermented milk improved the growth of Lactobacillus brevis and maintained their viability during the storage period (8 log CFU/g) and after digestion (7 log CFU/g). Carob fermented milk displayed higher TPC and higher antioxidant capacity during the storage. The digestion resulted in the release of bioaccessible phenolics where gallic acid (441%) and (+)-catechin (486%) were the most quantified phenolic compounds; thus, the inhibition of α-amylase (52%), α-glucosidase (37%) activity and higher antibacterial potential. These results demonstrate the potentials of carob fermented milk to be an important source of viable probiotics and bioaccessible polyphenols.
本研究旨在以短乳杆菌为分离菌株,以4%角豆粉为功能成分,开发一种新的益生菌合成发酵乳。在冷藏和胃肠道消化过程中,测定了角豆发酵乳的理化特性、益生菌活力、总酚含量(TPC)、抗氧化能力、抗菌活性和降糖活性。发酵乳中添加菌渣促进了短乳杆菌的生长,并在贮存期(8 log CFU/g)和消化后(7 log CFU/g)保持了短乳杆菌的活力。角豆发酵乳在贮藏过程中表现出较高的TPC和抗氧化能力。消化释放出生物可及的酚类化合物,其中没食子酸(441%)和儿茶素(486%)是定量最多的酚类化合物;因此,抑制α-淀粉酶(52%)、α-葡萄糖苷酶(37%)活性,具有较高的抗菌潜力。这些结果表明,角豆发酵乳有潜力成为益生菌和生物可及多酚的重要来源。

The exploration of naturally occurring phytochemicals with antitumor potential has been the focus of many studies. Nobiletin, a polymethoxyflavone (PMF) exclusively derived from citrus peels, has been reported as a promising candidate for the prevention and/or treatment of cancers. Additionally, multiple demethylated derivatives of nobiletin from in vivo biotransformation, including 3′-demethylnobiletin (3′-DMN), 4′-demethylnobiletin (4′-DMN), 3′,4′-didemethylnobiletin (3′,4′-DDMN) and 5-demethylnobiletin (5-DMN), among others, have been found to show anti-cancer activity. In this review, the anticancer activity of nobiletin and its derivatives in cancer prevention are comprehensively described.
探索具有抗肿瘤潜能的天然植物化学物质已成为许多研究的焦点。Nobiletin是一种从柑橘皮中提取的多甲氧基黄酮(PMF),已被报道为预防和/或治疗癌症的有希望的候选者。此外,体内生物转化的多种去甲基化皂素衍生物,包括3 ' -去甲基皂素(3 ' -DMN)、4 ' -去甲基皂素(4 ' -DMN)、3 ',4 ' -二去甲基皂素(3 ',4 ' -DDMN)和5-去甲基皂素(5-DMN)等,已被发现具有抗癌活性。本文就诺皮素及其衍生物在癌症预防中的抗癌作用作一综述。
