Seaweeds have been an important part of the diet of coastal populations in Asia possibly for millennia but only a few scattered coastal communities in Europe and the Americas have maintained these traditions. Our studies have investigated the potential of two tropical seaweeds grown commercially in Asia, Sarconema and Caulerpa spp., as functional foods for the reversal of metabolic syndrome and possible mechanisms. Sarconema spp. are a source of carrageenans used as thickening and gelling agents in foods, while Caulerpa spp. are consumed in Southeast Asia as low-energy foods with high contents of vitamins and minerals. For our studies, male Wistar rats were divided into groups in a 16-week protocol: corn starch diet-fed rats (C); C rats supplemented with 5% dried seaweed for the last 8 weeks; high-carbohydrate, high-fat diet-fed rats (H); and H rats supplemented with 5% dried seaweed for the last 8 weeks. H rats developed obesity, hypertension, dyslipidaemia, glucose intolerance, fatty liver and increased left ventricular collagen deposition, infiltration of inflammatory cells and plasma liver enzyme activities. Seaweed supplementation decreased body weight, abdominal and liver fat, systolic blood pressure, plasma lipid concentrations, plasma activities of liver enzymes and collagen deposition. Furthermore, seaweed supplementation modulated gut microbiota. Possible mechanisms for improved cardiovascular and metabolic health include a reduced infiltration of inflammatory cells into organs as well as an increased intake of fibre modulating gut microbiota composition.

“…But what are the obstacles? Obviously, tradition, culture, and availability are key factors (Mouritsen and Styrbæk, 2018 ; Pérez-Lloréns et al, 2020 ) and often also taste and texture are limiting factors. Our opinion is that by addressing precisely these two sensory aspects of impacting eating behavior we may have a chance of stimulating changes.…”

“…The number of countries that consume macroalgae as food has been increased, such as Japan, China, Hong Kong, Taiwan, Philippines, France, Scotland, Peru, Chile, Jamaica (Pérez-Lloréns et al, 2020). Nowadays it is possible to find Ulva snacks being sold in Portugal, Ireland, Germany, Brazil, among others.…”

Caracterização química, potencial antioxidante e atividade biológica de macroalgas arribadas do litoral brasileiro

A wide variety of metabolites extracted from macroalgae is currently used as functional food ingredients, natural nutraceuticals, biomedical materials, cosmetic formulations, as well as in other products that promote human health. One of the major limitations in the search for new extracts or natural products with biological action is the lack of available biomass for studies and even for their bioprospection. In this context, the availability of beach-cast marine algae is a sustainable and highly productive alternative. The main objective of this study was to evaluate the chemical and bioactive potential of extracts from 15 materials of beach-cast marine algae collected from the Brazilian coast to provide subsidies that allow identifying the potentialities and its uses as functional product. The findings showed that the highest antioxidant activities were found in extracts from brown beach-cast algae followed by the extracts of red beach-cast algae, and the lowest activities were detected in the green beach-cast species. The most efficient extracts of beach-cast species with antioxidant properties were from Dictyopteris jolyana, Zonaria tournefortii, and Osmundaria obtusiloba. Regarding antiviral activity, the aqueous extract of Codium isthmocladum and methanolic extracts from D. jolyana, Z. tournefortii Alsidium seaforthii, Spiridia clavata and O. obtusiloba were highly promising, reaching inhibition percentage above 90%. The extracts of Z. tournefortii, A, seaforthii and C. isthmocladum showed high cytotoxicity activity against the tumoral cells strains HL60 (leukemia) and HTC116 (colon) and did not show any cytotoxicity activity against non-tumoral human cells (HGF1). Currently, the large amount of beach-cast seaweeds deposited on the beaches of Brazil is collected and treated as trash, being incinerated or disposed in landfills by the government. Instead of using public resources and making efforts for the removal of this biomass, it is possible to propose different uses for the Brazilian beach-cast seaweeds and transform it into applications for several sectors. Due to the antioxidant, antiviral, nutritional, photoprotective and cytotoxic properties reported for macroalgae, such applied features bring environmental benefits by mitigating coastal pollution generating a usable resource, in addition to ensuring sustainable social and economic development. The review data shown in the literature of Brazilian beach-cast algae shows the relevance and innovation of this study. This is the first report evaluating chemical composition, antioxidant potential, antiviral activity, cytotoxicity potential and photoprotection of extracts from beach-cast algae from the Brazilian coast. The potential of beach-cast seaweeds provides raw-material for several applications, combined with the large amount available on the beaches of certain regions at the Brazilian coast can be better exploited. The present study significantly contributes to increasing knowledge of Brazilian beach-cast algae and their potential uses as well as t...
