Effects of Pesticides Carried by Foods on Human Gut Microbiota
The human gut microbiota is part of a delicate ecosystem that also involves the individual in which it is hosted and the environment. Humans and their gut microbiota depend on each other to maintain good health but many external factors can contribute to the disruption of this balance and lead to diseases. Pesticides are a good example of environmental pollutants to which humans are exposed on a daily basis mainly through diet. As a result the composition and functionality of the gut microbiota can be compromised as the gastrointestinal tract is the first physical and biological barrier with which they interact. Finally through multiple and complex mechanisms all this has repercussions on the health status of the host and the adverse effects of this gut microbiota–pesticide interaction can manifest themselves in various ways such as alteration of the diversity and abundance of the different bacteria both beneficial and pathogenic that colonize the gastrointestinal tract metabolic and endocrine disorders inflammation dysregulation of the immune system and neurological disorders among many others. Therefore this work aims to summarize the latest scientific evidence on the effects of pesticides on the gut microbiota and the possible implications for human health as well as animal models and in vitro cultures on which the different tests are carried out.
Pulses as Sustainable Protein Sources: Benefits, Drawbacks, and Gaps
Pulses have redeemed the interest in terms of a sustainable and healthy diet due to their high protein content. Furthermore the vitamins minerals and phytochemicals they contain also make them more valuable nutritionally. A sustainable diet should improve public health and food security and has a low environmental footprint. Pulses have been considered one of the emerging plant food proteins. Although they have beneficial components such as vitamins minerals phytochemicals and antioxidants many drawbacks limit their use to consumers and the food industry. One of the drawbacks is their incomplete proteins due to the lack of sulfur-containing amino acids in their protein profile. Furthermore the protein digestibility of pulses is low due to the antinutritional compounds they contain. The other drawback of pulses is their beany flavor and bitter taste that limits the acceptability of consumers. From the consumer's point of view the other disadvantage is the laborious and time-consuming preparation period.
This article provides a concise overview of the current state of knowledge on pulses as sustainable protein sources underlining the gaps that limit their extensive application in the food industry. Based on the available scientific facts on pulses finding an efficient method for removing beany flavor and overall sensorial acceptability and antinutritional factors thus increasing protein digestibility is crucial. The most promising option to increase pulse protein digestibility seems to combine conventional and novel technologies that can modulate digestibility by different mechanisms such as the removal of antinutritional factors protein denaturation and the design of the food matrix.
Effect of Prebiotic Supplementation on Probiotic Viability and Physicochemical Characteristics of Fermented Coconut Water with Bifidobacterium longum
Probiotics and prebiotics are functional ingredients that provide health benefits to consumers but they are mainly incorporated in dairy products. Designing a non-dairy product in which probiotics and prebiotics would be incorporated would allow more consumers to benefit from their advantages.
This study investigated the effect of supplementation of two different prebiotics fructooligosaccharide (FOS) and inulin on the viability of Bifidobacterium longum ATCC BAA-999 in coconut water.
Two concentrations of prebiotics used were 1% and 2%. The physicochemical characteristics of fermented coconut water with B. longum for 9 h at 37°C and during refrigerated storage at 4°C for 2 weeks were analyzed. The viability of B. longum in fermented coconut water was maintained above the recommended therapeutic level (7 log CFU/mL) with or without supplementation with prebiotics.
Most distinct changes in colour (∆E > 3) occurred in fermented coconut water compared to unfermented coconut water. An increase in the total soluble solids was also observed in fermented coconut water with the increase in the concentration of prebiotics. There were no significant changes in the clarity pH and concentrations of shikimic and malic acids in the fermented coconut water with or without supplementation with prebiotics over the 2 weeks of storage. Acetic acid production was observed in the fermented coconut water with the highest acetic acid production in the fermented coconut water supplemented with 1% FOS after 2 weeks of storage.
This study demonstrated the potential use of coconut water as a medium to produce a probiotic drink.
Fruits of Emblica officinalis Linn. and its Phytochemicals in the Prevention of Ethanol-induced Hepatotoxicity: A Mini-Review
Excessive alcohol consumption over time is one of the primary causes of liver disease and death globally. Because there is no effective treatment the situation has become more complicated and the emphasis has shifted to the use of alternative and complementary medicine to treat liver problems. Herbs with dietary use have played an important part in the treatment of liver diseases since antiquity. Amla or Indian gooseberry scientifically known as Phyllanthus emblica or Emblica officinalis is a fruiting plant of the Phyllanthaceae family that is used in a variety of traditional and folk medical systems. The fruits have both dietary and medicinal value and are used to prevent chemical-induced hepatocarcinogenesis and reduce experimentally induced hyperlipidemia and metabolic syndrome in laboratory animals. They also have hepatoprotective effects against a variety of hepatotoxins such as heavy metals iron overload ochratoxins hexachlorocyclohexane carbon tetrachloride therapeutic drugs such as paracetamol and antitubercular.
