Abstract(s)
Com o passar do tempo, os padrões alimentares sofreram processos de ramificação de
modo a adequarem-se a diferentes necessidades, surgindo abordagens dietéticas díspares.
Como tal, o objetivo desta investigação é identificar consequências metabólicas de duas
destas vertentes: a dieta paleolítica e a dieta vegetariana/vegan.
Assim, foi feita uma pesquisa bibliográfica com as expressões “paleolithic diet AND
metabolism” e “vegetarian diet AND metabolism” na base de dados PubMed e Scielo.
Por um lado, a dieta paleolítica tenta reproduzir um padrão alimentar mais próximo do
dos nossos ancestrais, preferindo alimentos provenientes da terra, da caça e da pesca.
Alguns estudos levantam a hipótese desta dieta apresentar benefícios na síndrome
metabólica. No entanto, pode promover um aumento do risco de deficiências vitamínicas
e minerais devido às restrições específicas inerentes a esta dieta.
Por outro lado, o vegetarianismo é um termo bastante vasto pois inclui diferentes
vertentes dependendo dos alimentos de origem animal que exclui sendo, de uma forma
geral, uma dieta à base de alimentos de origem vegetal. É estudada por diversos
investigadores que admitem a possibilidade da mesma diminuir o risco de
desenvolvimento de doenças cardiovasculares. Contudo, a adoção de uma dieta
vegetariana/vegan desequilibrada acarreta um aumento do risco de carências de alguns
micronutrientes derivadas da exclusão de grupos alimentares.
Assim, apesar de serem necessários mais estudos que clarifiquem os possíveis benefícios
e riscos de cada dieta, é possível concluir que qualquer uma delas deve ser devidamente
acompanhada nutricionalmente para permitir um aporte adequado de todos os nutrientes
necessários para a saúde.
Over time, the dietary patterns undergone branching process to adapt to dissimilar needs, hence arising different dietary approaches. As such, the purpose of this investigation is to identify the metabolic consequences of two of said strands: the Paleolithic diet and the vegetarian/ vegan diet. On this account, a literature research was made applying the expressions “paleolithic diet AND metabolism” and “vegetarian diet AND metabolism” in the PubMed and Scielo database. On one hand, the Paleolithic diet tries to reproduce a dietary pattern closer to those of our ancestors, mainly adopting foods from the land, hunting and fishing. Some studies suggest that the metabolic syndrome benefits from this diet, however, it can also promote an increased risk of vitamin and mineral deficiencies due to its specific dietary restrictions. On the other hand, vegetarianism is an extremely broad term, as it includes different regards depending on which animal products are being excluded, however being, in general, a plant-based diet. Researchers admit the possibility of it decreasing the risk of developing cardiovascular diseases; nevertheless, embracing an unbalanced vegetarian/ vegan diet leads to an increased risk of some micronutrient’s deficiencies due to the exclusion of certain food groups. As follows, granting more studies should be carried out to elucidate the possible benefits and downsides of each diet, embracing any of these should go along with a well considered plan that includes all nutrients indispensable for one’s health.
