OBESIDADE E A SUBSTITUIÇÃO DE MACRONUTRIENTES DA DIETA
Palavras-chave:
composição de macronutrientes, dieta, obesidadeResumo
Os fatores envolvidos na gênese da obesidade não são conclusivos, incluindo o papel dos macronutrientes da dieta na suscetibilidade ao ganho de peso. O carboidrato pode ser considerado um componente importante na saciedade. Sua substituição pelo adoçante, reduz o valor energético da dieta, reduzindo a massa corporal. Os efeitos dos adoçantes sobre o apetite dependem da natureza e da densidade dos nutrientes consumidos simultaneamente. Não existem evidencias suficientes que mostrem que os adoçantes causam ganho de peso, mas seu uso pode resultar em compensação energética com alimentos ricos em lipídios. Os lipídios tendem a aumentar a densidade energética da dieta promovendo o superconsumo passivo de energia, além de apresentar baixa prioridade oxidativa, estando associado à baixa saciedade. Sua substituição tem sido relacionada à compensação da ingestão energética, principalmente por carboidratos. Um plano alimentar disciplinado deve incluir alimentos que reduzam a densidade energética da dieta, sem promoção do consumo alimentar.
