In fact, the fungal metabolites produced by the species of Aspergillus, Penicillium (aflatoxins and ochratoxins), Fusarium (trichothecenes, zearalenones and fumonisins) and Alternaria (alternariotoxins) with toxic and/or carcinogenic effects are considered a threat to human and animal health. In this chapter we will discuss the main fungal taxa and related mycotoxins most frequently associated with these materials. In this regard, the first results on the level of contamination by fungi and mycotoxins in samples of almonds and pistachios of different origins will be reported. The main strategies to reduce the risk of contamination will also be recommended.","PeriodicalId":293214,"journal":{"name":"Nuts and Nut Products in Human Health and Nutrition [Working Title]","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125301408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Globally, the most popular edible nuts are groundnuts or peanuts, almond, cashew nut among others. Due to the rich nutritional composition of nuts, they tend to be prone to contamination by toxigenic fungi which could ultimately results in the release of fungal metabolites known as mycotoxins into nuts. In view of the nutritional composition of nut and its high susceptibility to fungal attack, this chapter looks at the nutritional profile, mycotoxigenic fungi and aflatoxins contamination of peanuts, cashew nuts and their products with a central focus on Africa where the effect of aflatoxin contaminations is more prominent.","PeriodicalId":293214,"journal":{"name":"Nuts and Nut Products in Human Health and Nutrition [Working Title]","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131224709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to 2005 “My Pyramid” it has been grouped with the meat and bean group. Bioactive compounds of nuts such as resveratrol, phytosterols, phenolic acids, flavonoids, and carotenoids display synergistic effects on preventing many age related pathologies. Resveratrol has been reported to extend the lifespan in model organisms such as yeast, Drosophila and mouse. Reports propose nuts as the best substitute for red meat to reduce mortality risk. Macadamia nuts with a rich source of monounsaturated fats (oleic and palmitoleic acids) imparts cholesterol lowering effects thereby preventing coronary artery disease. Anacardic acid, a phenolic lipid found in cashew nut shells, is specifically enriched in metastatic melanoma patients in response to immunotherapy. The non-bio-accessible materials of nuts serve as a substrate for human gut microbiota. Regular Walnut enriched diet improves lipid content and enhances probiotic and butyrate producing bacteria composition in healthy individuals. This also reduces cardiovascular risk factors by promoting beneficial bacteria. Gut microbiota diversity studies report an enrichment with genera capable of producing short chain fatty acids (SCFA) following consumption of nuts. The prebiotic effect of nuts can be partly from refining butyrate producing bacteria composition. Hence an optimized diet rich with nuts can be an intervention for promoting a healthy microbiota population and thereby improving overall physiology.","PeriodicalId":293214,"journal":{"name":"Nuts and Nut Products in Human Health and Nutrition [Working Title]","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125945316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nuts are the integral part of the Mediterranean diet and advised to be incorporated in diet for health benefits. Both tree nuts and pea nut are good source of unsaturated fatty acids, soluble and insoluble fibers, good quantity of vitamins, minerals and phytochemicals with recognized benefits to human health. Due to life style disorders many chronic diseases are increasing in human beings. There are many epidemiological studies and research conducted on the relationship between consumption of nuts and chronic disease risks. This book chapter elaborately discusses about the nutritional composition of the nuts and their effect on cardiovascular disease, obesity, diabetes and cancer.","PeriodicalId":293214,"journal":{"name":"Nuts and Nut Products in Human Health and Nutrition [Working Title]","volume":"677 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129781892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
