Table

Table 1. : The chemical composition, especially antioxidants, of Brazil nuts and the health effects related to its regular consumption
 
SubjectKey findingsReferences
Hydrosoluble phenolic compoundsPredominately found in the brown skin that covers the kernel, detected so far are phenolic acids and flavonoid derivatives like gallic acid, gallocatechin, protocatechuic acid, catechin, vanillic acid, taxifolin, myricetin, ellagic acid, sinapic acid and quercetinJohn and Shahidi (2010); Gomes and Torres (2016)
Relevant amounts of ellagic acid derivatives found in aqueous extracts of bark biomass residues of the Brazil nut treeSilva et al. (2019)
TocopherolsBrazil nut has remarkable levels of delta-tocopherol, in comparison with other tree nutsMiraliakbari and Shahidi (2008b)
SeleniumSelenium levels vary significantly depending on the nut origin. Therefore, recommendations of adding Se levels information based on the origin of the seeds in retail labelling should be madeSilva Jr. et al. (2017)
Effects of processing on nutrient levelsSelenium levels decreased up to 73% during water-extraction processSartori et al. (2020)
Alpha-tocopherol losses are higher than gamma-tocopherol losses in Brazil nut oil during storageSartori et al. (2018a)
Health effectsNo selenosis reported in health populations with diets rich in selenium from Brazil nutsMartens et al. (2015); Lemire et al. (2012)
Consumption of Brazil nuts with high Se levels may have a pro-inflammatory effect in obese womenDuarte et al. (2019)
Anti-cancer and antioxidant effects related to a regular Brazil nut consumption was reportedCardoso et al. (2017)
